			<content:encoded><![CDATA[<p><strong>If cleanliness is next to godliness, then fish must be downright saintly.<br />
By Suzanne Gerber ~ Photos and Captions By Barbara Shively</strong></p>
<p><em>Doesn’t living 24/7 in the ocean keep fish clean, you ask? Not exactly. While they don’t need to hit the showers like we do after two sets of tennis, they still need to have their dead skin and scales removed, as well as tiny parasites that live on their bodies and inside their mouths. Left unattended, the parasites will multiply and eventually kill the fish.</em></p>
<p>Without the benefit of hands (or Waterpiks), getting rid of parasites can be a bit challenging, to say the least. But fish have worked out an effective system that’s mutually beneficial to themselves and their designated hygienists: cleaning stations! These distinct areas can be located right on a coral reef head, under it (especially with shrimps), between outcroppings, underneath clumps of floating seaweed or right out in public, in the water column. The “client” fish receives a first-rate spit-and-polish job, while the cleaner gets a free meal. It’s a beautiful thing — and it’s a classic example of symbiosis, or mutualism, an ecological interaction that benefits both the party of the first part and the party of the second part.</p>
<div id="attachment_2196" class="wp-caption alignleft" style="width: 250px"><a href="http://www.timespub.tc/wp-content/uploads/2012/01/B-Tiger-grouper-open-mouth-.jpg"><img class="size-medium wp-image-2196" title="B-Tiger-grouper-open-mouth-" src="http://www.timespub.tc/wp-content/uploads/2012/01/B-Tiger-grouper-open-mouth--240x300.jpg" alt="" width="240" height="300" /></a><p class="wp-caption-text">Tiger Grouper at a cleaning station.</p></div>
<p>Snorkelers and new divers are always amazed when they realize they’ve stumbled upon such a set-up. (And trust us, it’s a sight to behold: large groupers saying “ahh!” as tiny dentists dart in and out of their gaping gobs; parrotfish hovering statue-still on a 45º angle while slender yellow fish work their magic like Tinkerbell.) Fish great and small, turtles and even sharks come in for regular cleanings, and the specific attractive behaviors will vary depending on the species. The most common cleaning fish in these parts are wrasses and gobies, but shrimps are also experts at removing parasites, bacteria and dead skin, and occasionally catfish have been known to perform ablutions. (But beware the saber-toothed blenny, who mimics cleaner fish but in fact feeds on healthy scales and mucus.)</p>
<p>You may wonder how the groomers find their clients without the benefit of social networking. Actually, there are a few different ways, and they involve some complex behaviors that we usually associate with humans and primates (kind of like the fish equivalent of a secret handshake). Sometimes the cleaner advertises his services, typically by sporting a “uniform” that serves as a signal to potential customers (which is doubly clever, says a new study, as it also helps the fish avoid being eaten by their clients, which is never a good business model).</p>
<p>When a potential “host” approaches a cleaning station, he will open its mouth wide or position himself in a way that indicated he needs cleaning. Sometimes hosts congregate and perform specific movements together to attract the attention of the cleaner fish. Apparently those moves save their lives, as somehow this further signals to the potential predator that these small fry are off the menu.</p>
<p>Scientists have long wondered about this interaction, so an Australian researcher, Karen Cheney, and her colleagues recently decided to test the “uniform” theory, which holds that colors and body patterns are what set cleaners apart. And with some creative testing methods, including painting fake fish and attempting to lure clients, they discovered that the color theory holds water, so to speak, and that cleaner fish are more likely to sport a dark side stripe accentuated by patches of blue and yellow.</p>
<div id="attachment_2197" class="wp-caption alignright" style="width: 310px"><a href="http://www.timespub.tc/wp-content/uploads/2012/01/A-2-AnemoneWithPedersons-.jpg"><img class="size-medium wp-image-2197" title="A-2-AnemoneWithPedersons---" src="http://www.timespub.tc/wp-content/uploads/2012/01/A-2-AnemoneWithPedersons--300x198.jpg" alt="" width="300" height="198" /></a><p class="wp-caption-text">Giant anemones are a favorite home to several kinds of cleaners.</p></div>
<p>Shrimp are a whole other matter. Take the Banded Coral Shrimp, for instance. None of this “flashing some tacky blue and yellow costume and waiting around in the open water for just anyone to come in and ask for a clean-up job” for him. This highly specialized cleaner of larger fishes sleeps by day, and then as the sun goes down, begins his patient wait until his discerning clientele come swimming by under the cover of night. And his way of attracting business is stage-worthy: this crafty cleaner performs a discreet dance in which he shakes his white antennae and banded body — while hanging upside-down under a small coral head.</p>
<p>Divers love to get in on the cleaning action. You’ve heard of a French manicure. Well, Barbara and I have both gotten what’s known in the biz as a Pederson Manicure. And you, too, can get a professional nail job while snorkeling or whiling away the last three minutes of your dive doing your shallow-water safety stop. Search out an anemone (Barbara looks for corkscrew anemones like the ones in these photos) then gently place your hand in front of it and wait. (You’ve got at least three minutes of bubble time before you come up, so why not?) In pretty short order, one or possibly several Pederson cleaner shrimp will show up, climb onto your fingers and get busy clearing out the dead skin around the fingernails — and whatever else may be on your fingers. Sometimes cleaner gobies will join in and clean up and down your entire hand. And while we have never done this, we’ve seen other, more adventurous (or dirtier) divers who’ve found a cleaning station remove the regulator from their mouth, open wide and invite cleaner shrimp to come in and clean their teeth!</p>

<p>Once you know what you’re looking for, you’ll not only never miss a cleaning station again, but you’ll no doubt seek them out. And yet, as common as they are, trying to find and photograph the creatures for this article presented Barbara with a couple of serious challenges. First, she said, coming upon fish being cleaned without disturbing them is a lot tricky than you’d think. And then she confronted the added difficulty of finding those teeny, tiny cleaner shrimps as they hid in various anemones. We’re talking about creatures ranging in length from an inch or two down to less than a quarter-inch! Barbara claims she needs bifocals in her dive mask, but I think she did a pretty amazing job with these photos. And you should see her nails: divine!</p>

			<content:encoded><![CDATA[<p>By Dr. Peter Sinelli and Dr. William Keegan ~ Original Artwork by Theodore Morris</p>
<p><em>For every complex problem there is an answer that is clear, simple and wrong.</em><br />
H. L. Mencken</p>
<p>	During our travels virtually everyone we meet has heard of the Arawaks and the Caribs. James Michener’s hugely popular novel established these as the Caribbean’s native peoples and forged the dichotomy of peaceful Indian and fierce cannibal. In doing so he followed a literary tradition that traces its roots to the 16th century. Indeed, the story of the “nice Indians versus the mean Indians” has been repeated so many times that it must be correct, right?<br />
	The next question always seems to be “Where did they come from?” Because most of the Bahama islands are off the east coast of Florida, people often assume that the native peoples must have come from there. They are surprised to learn that the native peoples of the Caribbean Islands (including Bahamas and Turks &#038; Caicos) can trace their ancestry all the way to mainland South America, thousands of kilometers distant. There is virtually no evidence for any migrations from Florida into the islands. Our audiences liked the idea that the native peoples came from “Amazonia,” as it gave the islands a more exotic ambience, especially when headhunters were added in!<br />
	Getting from South America to the Turks &#038; Caicos sounded like a nearly impossible task (in fact, getting to the Turks &#038; Caicos as recently as 30 years ago was a nearly impossible task). However, archaeologists had a simple explanation, and we will start with that. This is the (hi)story we have recounted innumerable times with complete scientific confidence. After we tell the story, we will explain why it is wrong in our next essay, in the next issue of Times of the Islands. Our final caveat: archaeologists have assigned specific names to the peoples who occupied the islands, but for our purposes it is sufficient to think of the migrants as Island Arawaks.<br />
	<div id="attachment_2126" class="wp-caption alignleft" style="width: 310px"><a href="http://www.timespub.tc/wp-content/uploads/2011/10/Campsite.jpg"><img src="http://www.timespub.tc/wp-content/uploads/2011/10/Campsite-300x223.jpg" alt="The Shelter" title="Campsite" width="300" height="223" class="size-medium wp-image-2126" /></a><p class="wp-caption-text">Arawak hunter eating a meal in a cave.</p></div>Here’s how the story goes:  Long, long ago in a faraway, exotic place, large dugout canoes that the Indians used  to navigate the major inland waterways of South America (Amazon and Orinoco River drainages around 1000 BC), were adapted to open water conditions after the Arawaks reached Trinidad. From Trinidad it was a relatively short paddle to Grenada (about 130 km). Although Grenada is not visible from the mainland, there are cloud and weather patterns and bird migrations that make its presence known to the careful observer. Better still, from Grenada there are always other islands visible on the horizon to the north all the way to the Virgin Islands and Puerto Rico. It may have taken a few centuries to migrate that far (that takes us to 500 BC for those keeping score), but now they were less than 400 miles from Grand Turk (which they still didn’t know was there).<br />
	After reaching Puerto Rico, the Island Arawaks settled down for nearly 1,000 years (to AD 500). It is possible that their migration stopped because they reached islands that had established populations. The Greater Antilles were colonized about 4,000 years earlier by Archaic hunter-gatherers who migrated from Central America. Did these people prevent the Island Arawaks from expanding into Hispaniola? Did the lifeline that connected the people of Puerto Rico with those of the Orinoco delta become so stretched that a period of population growth and stabilization was needed in the Lesser Antilles? These are interesting questions, but let us remind you that they are no longer relevant. The solution comes from asking a different question.<br />
	The millennium in Puerto Rico wasn’t wasted. A new kind of pottery was invented, new tools became important, and the land was cleared and farmed. In sum, their adaptation to island life was nearly complete. These new and improved Island Arawaks were no longer intimidated by the Archaics and they swept through the Dominican Republic, Haiti, Jamaica, and Cuba, as completely and inevitably as the tide that washes away a child’s sand castle. The Archaics were pushed aside until they occupied nothing more than a small region at the tip of western Cuba. The Island Arawaks also began visiting the Turks &#038; Caicos by AD 700, based on a radiocarbon date from the Coralie site on Grand Turk.<br />
	The Turks &#038; Caicos proved to be an amazing place with an abundance of sea turtles, large fishes, giant iguanas, conch, lobster, birds, and Galapagos-size tortoises. All of the food resources that had long-since been consumed on Hispaniola  could be picked, plucked, trapped, or snagged with about the same effort it takes one of us to hit a buffet line. To people accustomed to a depleted ecology, the virgin environment of the Turks &#038; Caicos was  a veritable paradise.<br />
	Even though food was abundant, life in the Bahama archipelago presented a new problem. There was no clay or igneous rocks for the manufacture of pottery. The Island Arawaks adapted to these islands by making crude pots from the clay-like Bahama Red Loam (“pineapple soil”) and they replaced stone with shell temper. This distinctive pottery has been used to distinguish these people, who the Spanish called Lucayans (literally “island men”), from their ancestors to the south. From the Turks &#038; Caicos they expanded north into the rest of the Bahamas (circa AD 1000).  By 1492, when the Lucayans on San Salvador discovered Columbus, who was so hopelessly lost he thought he was off the coast of Asia, the Island Arawaks had colonized all of the larger and most of the smaller islands of the Caribbean. The absence of evidence suggests that only the Cayman Islands and Bermuda (if we can include this northern isolate) were never settled.<br />
	At the beginning of the 15th century archaeologists recognize that three major Cultures were operating in the islands: the Lucayans in the Bahama Archipelago, the Tainos in the Greater Antilles, and the Ignerí in the Lesser Antilles. All three are derived from the expansion of peoples from the Orinoco delta in what is today Venezuela that began around 500 BC. The Spanish conquest quickly decimated the northern islands beginning at the end of the 15th century. A separate assault began in the mid-1400s as fierce cannibals from South America invaded the Lesser Antilles. They “ate the Arawak men and married the Arawak women” as they moved north from Grenada to Guadeloupe. It was in Guadeloupe that Columbus first encountered them on his second voyage. He had, of course, been warned about these fierce “dog-faced” peoples by the northern Arawaks he encountered on his first trip, so he did his best to limit his contact with them. And they lived happily ever after. The End.<br />
	Our story is like the Arawak version of a Royal Caribbean cruise itinerary for the ancient human colonization of the insular Caribbean. (Note: Carnival wouldn’t pay for product placement.) Essentially, you board the ship in Port of Spain, Trinidad and travel north with stops in Grenada, Antigua, St. Thomas (“duty-free” stop), and San Juan. Next stop is Labadee (west of Cap Haitian), but don’t mention you are in Haiti — “it’s our own private island.”  You could go on to Ocho Rios, Jamaica, but we are on a mission headed north. From Haiti it’s a short hop to Grand Turk, then to Nassau, and finally Miami.<br />
	At the beginning we noted that there was little evidence for contacts between Florida and the islands. The Gulf Stream presents the main barrier. Thus, although it is possible to use this current to travel from the islands to the east coast of Florida, it is extremely difficult to travel from Florida to the islands (unless that island is Ireland!) The story is so neat and logical that it all makes perfect sense. You start on one island and see another to the north. You go to that island and see another on the horizon. You go to that island and continue until all of the islands have been colonized. Hopscotch!<br />
	Mr. Mencken was right. There is a clear and simple outline for the prehistoric colonization of the insular Caribbean. But it is wrong. We will explain why in our next essay.</p>

<p>It doesn’t matter whether you call them perroquetfeu, loro colorado, Budião-Vermelh, sparysoma szmaragdowa, or parrotfish, these beautiful creatures are among the most beloved in the underwater menagerie. Nor does it matter whether you speak French, Spanish, Portuguese, Polish or English. It’s not hard to puzzle out how the parrotfish got its avian appellation: those bright colors and prominent, beak-like teeth.<br />
	<div id="attachment_2061" class="wp-caption alignright" style="width: 310px"><img src="http://www.timespub.tc/wp-content/uploads/2011/06/D-BestInitialStoplightParro-300x179.jpg" alt="Stoplight Parrotfish initial phase" title="D-BestInitialStoplightParro" width="300" height="179" class="size-medium wp-image-2061" /><p class="wp-caption-text">Stoplight Parrotfish initial phase</p></div>Here in the Caribbean we don’t have the jumbo-size species like the bumphead or humphead parrotfish, which can grow to more than four feet and tip the scales at more than 100 pounds, but we do have dozens of dazzling species. And when you learn a little more about these amazing creatures, you will start to appreciate them on an even, um, deeper level.</p>
<p><strong>Front and center</strong><br />
<div id="attachment_2062" class="wp-caption alignleft" style="width: 310px"><img src="http://www.timespub.tc/wp-content/uploads/2011/06/L-AllBestRedbandParrotfishC-300x193.jpg" alt="Redband parrotfish varied colors and patterns" title="L-AllBestRedbandParrotfishC" width="300" height="193" class="size-medium wp-image-2062" /><p class="wp-caption-text">Redband parrotfish varied colors and patterns</p></div>One of the most striking things about this family of fish is how dramatically its members change color (and change sex! But more on that later) and how different the same fish will look when’s he’s a juvenile, a teen and finally a mature adult. Barbara’s photos are not only beautiful, but they’re highly instructive, and the captions clearly illuminate specific color changes, which makes it (relatively) easy to determine where in his life cycle any given loro colorado is.<br />
	And those teeth! They’re not just an amusing spectacle. They perform an important function in the perroquetfeu’s life. These chompers, which actually form a bill, are used to gnaw off pieces of coral. Yet it’s not the crunchy coral skeleton that they’re after: it’s the polyps that grow on the surface and contain the nutritious <em>zooxanthellae</em> algae.<br />
	The coral-munching serves an additional purpose for these clever critters. Many species have a second pair of (flat) teeth inside their throats, to help them grind down the coral, which then passes through their system and is eliminated in heaps that resemble sand piles. But these droppings aren’t random. Like Hansel and Gretel’s bread crumbs, they are strategically dumped, if you will, to help the parrotfish navigate their way to and back from their nocturnal nests. It’s hard to fathom, but parrotfish can produce up to one ton of coral sand per acre of reef every year. And, notes Jodi Johnson, an environmental officer in the TCI’s Department of Environment &#038; Coastal Resources on Grand Turk, “It comes out nice and crumbly, which helps to make and maintain some of that  beautiful sand and shoreline that we and our visitors love to walk on.”</p>
<p><strong>Nocturnal nests</strong><br />
<div id="attachment_2063" class="wp-caption alignright" style="width: 232px"><img src="http://www.timespub.tc/wp-content/uploads/2011/06/I-Redtail-Parrotfish-threes-222x300.jpg" alt="Redtail Parrotfish various stages" title="I-Redtail-Parrotfish-threes" width="222" height="300" class="size-medium wp-image-2063" /><p class="wp-caption-text">Redtail Parrotfish various stages</p></div>Night divers love to learn about fishes’ after-hours activities. And one of the most unique behavioral patterns is the parrotfish’s nighttime cocoon, which is made of a slimy mucus that’s produced by their skin glands. This half-hour-long show starts every night at sunset. The coating smells rank, but that’s actually a good thing (well, if you’re a parrotfish). In addition to the physical protection the cocoon provides, its smell is an additional deterrent to would-be predators. There’s an opening in the front with a flap that lets water in, and another at the back that lets it out, allowing the fish to breathe, though the rate is greatly reduced during sleep. Once his morning alarm goes off, the fish spends another half-hour breaking out of his cocoon before heading to work.<br />
	Parrotfish are famously adept navigators, returning night after night to the same slumber ledges or “caves.” And when they’re frightened during daylight hours, they make a beeline for those quarters. The accuracy of this behavior piqued researchers’ curiosity enough to lead a group to study it. First, they covered the opening of the cave with a net and then agitated the fish. Result: the fish swam into the net and waited until it was eventually lifted. When clouds would cover the sun or when the scientists intentionally “blindfolded” the fish with removable suction cups, they would swim in the wrong direction. But every time they had their vision in full light, the fish reached their sleeping quarters swiftly and directly, leading the researchers to assume vision plays an integral role in their navigation.</p>
<p><strong>Sex lives of Parrotfish</strong><br />
Unlike <em>homo sapiens</em>, who have countless ways to court and romance, scarus ceruleus have but two styles of reproduction. Parrotfish spawn year-round, though they seem to favor summer months. (And one fussy variety, the Redbill, does it only in the afternoon. Don’t ask.) Of the two basic reproduction “techniques,” the first requires large assemblies, where mostly males move away from their feeding grounds into 65 to 70 foot water. Periodically, 4 to 13 males will leave the pack and swim upward, releasing into the water both eggs and sperm (technically called milt, which is a fluid containing the sperm). The second technique (the more romantic one, in our book) involves one male and one female swimming upward together in the water column, circling each other, then releasing egg and sperm in a cloud that resembles milk. A day later this will hatch, and out will swim more females than male, though they are indistinguishable at this stage. Some males will mature into small adults and be called primary males. Others will grow larger and be called secondary, which tend to be solitary and dominate a sexual territory—and their very own “harem.”<br />
	Perhaps the most fascinating thing about our friend the sparysoma szmaragdowa is this whole sex-change business. Parrotfish are born with both sets of sex organs and can start off as either gender. Those born male will stay male, though they’ll never become what’s called a dominant male. Interestingly, that role is played by fish that start off female and morph into a supermale (usually when male populations begin to dwindle). These large fish, called terminal-phase males, have bright, distinctive markings and colors, which attract the females. (In courtship, the supermales’ colors grow even more brilliant.) Sex change in parrotfish ensures there will always be a male to reproduce with all the females. And that’s important to the species and to us, because who could imagine coral reefs without its brightly colored birds?</p>

<p>One of the most unique and important archaeological sites in the Caribbean is located on the south shore of Middle Caicos. Various archaeologists have worked at the site since 1912, continuously trying to answer new questions with new techniques. In May and June 2010, I returned to Middle Caicos to investigate salt production on Armstrong Pond. We were living at the Turks &#038; Caicos National Trust research facility in Bambarra, and greatly appreciate the assistance of their Director Ethlyn Gibbs, and permission to conduct the research granted by Wesley Clerveaux and Eric Salamanca of the Department of Environmental and Coastal Resources.</p>
<p>	The site, known as MC-6, is a 3.5 km trek through the bush. Although a trail had been cut and partially maintained, it was mostly reclaimed by dense vegetation. We spent six eventful days re-cutting the trail, eventually losing it just north of the pond where Hurricane Ike had particularly devastating consequences. Working in the pouring rain, swarmed by the worst mosquitoes in living memory on Middle, breaking a machete on a particularly hard tree, and at first-go missing the pond to the east, we eventually reached our destination. Although we cursed the days spent clearing the trail, we were rewarded by the discovery of the site and the desolate salina of incomparable beauty.<br />
	<div id="attachment_1938" class="wp-caption alignleft" style="width: 310px"><img src="http://www.timespub.tc/wp-content/uploads/2011/03/IMG_1086-300x225.jpg" alt="Armstrong Pond, Middle Caicos" title="IMG_1086" width="300" height="225" class="size-medium wp-image-1938" /><p class="wp-caption-text">Armstrong Pond, Middle Caicos</p></div>The salina is a very flat area just south of Middle Caicos and stretches between true dry land of Middle and the Caicos Bank. Even with a slight increase of water level, by a hurricane or a storm, the salina is under water. But in prehistoric times, this area was inundated and the settlement did not border a salina but had immediate access to the Caicos Bank. Although access to the marine resources of the Caicos Bank was of significance for these people, other locations in the Caribbean are also known for their fertile marine banks. In addition, an enormous amount of marine resources was not necessarily needed, because Middle Caicos never harbored a large population in prehistoric times. Transport of fish to Hispaniola, where large populations were living and, especially in the interior, needed fish and proteins to supplement their diet, was prohibited by preservation issues. A canoe trip to Hispaniola, a 120 km voyage, lasted at least a couple of days and transport to the interior added more time to this journey. By the time the fish arrived, it would have rotted and been inedible. So why is MC-6 so important?<br />
	The answer to that question is salt. The settlement connects through an indigenous road to the mile-long hypersaline Armstrong Pond. Especially in summer, this pond produces enormous amounts of salt and a crew of 15 people have collected over a ton of the “white gold” in 15 minutes during an archaeological project led by Shaun Sullivan in the late 1970s/early 1980s. (Salt has been known in historic times as “white gold” for its high value and price.)<br />
	Besides the dietary need of salt in a human diet, salt is a preservative. The fish could be caught on the Caicos Bank and immediately salted, preserving the meat over much longer periods of time. The presence of salt enabled people to catch fish and transport it to Hispaniola. At the time that MC-6 was inhabited (around AD 1200), archaeological deposits on the coast of Hispaniola already showed signs of overfishing and the lack of large mammals on Caribbean Islands forced people to rely on fish for their proteins. The combination of both salt and fish relatively close to the chiefdoms of Hispaniola became a powerful resource for elites to control, because they could supply these essential resources to large populations. Their ability to supply these goods to recipients and followers must have been reflected in an increase of social status and power among the chiefs.</p>
<p><strong>Fieldwork this summer</strong><br />
To understand the exact relationship between salt and MC-6, we needed to look at Armstrong Pond and the settlement in more detail. In previous research, it was always assumed that salt was produced approximately 500 years ago, but information on Armstrong Pond’s past was not available. Furthermore, the stone circles that surround the plaza at MC-6 were considered houses or storage facilities for salt and salted fish, but detailed excavation data was also lacking. These two locations, the pond and the stone circles, were targeted this year for study.<br />
	At Armstrong Pond, over 50 cores were taken from the middle of the pond. We had to walk into the pond with a corer and push it into the sediment. Because the corer was made of transparent plastic, we could analyze the sediments immediately and photograph them in their original context. The idea behind the coring was to investigate the history of the pond, because the lower sediments in the core were deposited earlier than the sediments on top. By going down in the deposits, you can go back through time and see what happened in the past.<br />
	Another quality of sediments is really important for this sort of analysis. Different sediments, like clay, silt or sand, settle in different circumstances and give information on previous environments. Clay and silt depositions only settle when the body of water is barely moving, and especially clay is only expected in circumstances without any currents. The larger fractions, such as sand and small rocks, will only deposit while water is still flowing. In other words, clay and silt are only expected in relatively stable environments, while sand suggests a more dynamic context.<br />
	Armstrong Pond is today disconnected from the sea and water input is dependent on rainwater and the filtration of sea water through the subsoil. Both inputs are under relatively low velocity, which was underlined by the clay and silty top-layer in all the cores across the pond. However, in most cores from Armstrong Pond, we found multiple layers of sand. These layers of sand must have been deposited at times when water was flowing into the pond and water levels were higher as they are now. Hurricanes can cause significant short-term increases of water tables, but it is also possible that the water table was structurally higher for a period of time. Dating the different layers, which is planned for 2011, will illuminate the time-line of these events.<br />
	Archaeological excavations at the settlement were focused on the stone structures and were aimed at explaining the original function of these structures. All locations were carefully recorded and artifacts were collected in 10 cm levels to describe the chronology. This principle works the same as for the sediments in the pond, where older artifacts are located in the lower levels of the excavations. Separating the artifacts in different levels enables us to discuss changes through time based on the artifacts that were found.<br />
	The settlement was full of artifacts. We encountered numerous pottery sherds, fauna material and pieces of coral and shell that were obviously modified after their use as tools. Some pottery, known as Palmetto Ware, was locally produced, but other styles, such as Meillacan, Ostionan and Chican pottery came from Hispaniola. These pottery sherds had little pieces of volcanic rock in them and because volcanoes are absent in the Bahamian archipelago, these needed to have come from elsewhere. The pottery sherds are clear evidence for contact with Hispaniola and other islands.<br />
	Most faunal material was fish bones, but birds, iguanas, hutias (small rodents that were endemic to the Caribbean) and turtles were also represented. This shows that Lucayan people had a large variety in their diet and although fishing practices were common, other resources were not untouched. The Spanish have mentioned that iguanas and hutias were exclusive foods for chiefs and commoners, which suggests that MC-6 was inhabited by elites and that special dinners were prepared and consumed here.<br />
	Lucayan people, as many other groups in the Caribbean, used shell and coral as tools. The lip of Queen Conch, for example, could be used as an ax to prepare gardens and chop down trees. Bivalves, such as Codakia orbicularis, could be used as scoops for food, shell net weights or scrapers for pottery making. The rough outside of coral could be used for modifying wood or grinding corn and manioc, staple foods in Lucayan diets. Besides these functional roles, shell was also used for decorative purposes and beads, shell inlays in wooden artifacts, and decorative pieces were found as well.<br />
	Good archaeological practice means that old assumptions and new hypotheses are constantly questioned and tested. Despite the obvious geographical relation between MC-6, the Caicos Bank and Armstrong Pond, we cannot assume that people were using salt to preserve fish without strong archaeological evidence. This summer&#8217;s project focused specifically on the availability and use of salt as an economic resource at this prehistoric site. The recovered data allows us to make more detailed statements about the practices of the people living at MC-6 and how they used resources from their environment to make a living. Finally, the excavations will also shed light on the importance of salt in prehistory, as this “white gold” has been neglected in many archaeological studies in the Caribbean region.</p>

<p>Like the denizens of Lady Gaga’s demi-monde, the creatures who come out at night on the coral reef are a psychedelic parade of colors, shapes and textures. A nighttime visit to the reef is an entirely different experience than what you find during daylight hours. Hard corals that resemble stones by day become flamboyant showgirls by moonlight, as they shimmy and shake their boa-like tentacles to feed in the evening sea. Like nocturnal club kids, critters that are shy and elusive in the stark light of the sun let their hair down after dark. Introverted cliques of cardinal, squirrel and soldierfish become wild and wooly under cover of darkness. Crustaceans as a group are almost totally transformed. Reclusive crabs, octopi and certain species of lobsters come out of their closets to cruise the reef in search of dinner, a midnight snack, or perchance just a surreptitious hook-up.</p>
<p>	<div id="attachment_1899" class="wp-caption alignleft" style="width: 241px"><img src="http://www.timespub.tc/wp-content/uploads/2011/01/V3-Open-Corals-At-Night-231x300.jpg" alt="Giant star coral and orange cup coral" title="V3---Open-Corals-At-Night" width="231" height="300" class="size-medium wp-image-1899" /><p class="wp-caption-text">Giant star coral and orange cup coral</p></div>Barbara and I have both had quasi-religious experiences on night dives. One of the most awesome experiences of her life occurred on a “dark of the moon” night dive (a few days after a full moon, when that heavenly body doesn’t rise till late evening) off Grand Turk. During the briefing, the group was told that at the end of the dive they were to gather together, switch off their lights, and wait on the sandy bottom. She recalls being a bit nervous, yet she trusted her divemaster. After a minute or two, when her eyes had adjusted to the pitch darkness, she beheld a vision that looked to her as if the sky had fallen and landed on the ocean floor. The longer she sat there, the more “stars” she saw. They were so close it seemed as if she could reach out and touch them. “If you can imagine sitting in the middle of the sky surrounded by millions of stars, you begin to get the idea what we were feeling,” she says, adding that she’s had that experience several times since, “and the magic never lessens. This is impossible to capture with a camera — regrettably — but it is an image I will carry in my mind forever.”<br />
	<div id="attachment_1900" class="wp-caption alignright" style="width: 310px"><img src="http://www.timespub.tc/wp-content/uploads/2011/01/H8-Regal-Slipper-Lobster-300x199.jpg" alt="Regal slipper lobster foraging after dark" title="H8---Regal-Slipper-Lobster" width="300" height="199" class="size-medium wp-image-1900" /><p class="wp-caption-text">Regal slipper lobster foraging after dark</p></div>What Barbara and her dive buddies were seeing was the bioluminescent plankton that float in the water — like underwater fireflies. Marine biologists estimate that 90% of all sea creature emit some form of bioluminescence. Under certain conditions, you can actually sit in a boat, wave your hand through the water, and watch the water light up. When you’re diving, you learn early on to briefly hold your dive light over your gauges, and when you remove it, the dials glow in the dark. Bioluminescence—for my fellow language geeks — comes from the Greek word bios (“living”) and the Latin lumen (“light”).<br />
	<div id="attachment_1901" class="wp-caption alignleft" style="width: 242px"><img src="http://www.timespub.tc/wp-content/uploads/2011/01/V5-Sleeping-Scrawled-File-232x300.jpg" alt="Scrawled filefish sleep at night without changing colors" title="V5---Sleeping-Scrawled-File" width="232" height="300" class="size-medium wp-image-1901" /><p class="wp-caption-text">Scrawled filefish sleep at night without changing colors</p></div>I’ve done plenty of night dives in the TCI, which are stunning because of the amazing clarity of the water. But my first-ever night dive was in Cozumel, and like many first-timers, I approached it with great trepidation (“What if my batteries die?” “What if I lose you guys?” “What if I don’t see something and it bites me?”). Yet I had heard such incredible things and was determined to tough it out. We hit the water just before the sun was setting. It was warm and calm, and we landed in a shallow sandy patch just in time to see a long-legged crab strutting his stuff across the shoal. As the light dimmed, we finned around and found a fearless octopus, presumably out for dinner. But first she was determined to give us a show: changing colors and gliding over small coral heads and  letting us stroke her preternaturally soft body — normally a big no-no for divers! Later in the dive, a precious, box-shaped trunkfish literally swam into my hands and wouldn’t leave when I tried to push him away. I “handed” him to my dive buddy, who had the same experience. We actually keep little “Trunkie” with us for the entire dive. Never since have I had an experience to rival that.<br />
	<div id="attachment_1902" class="wp-caption alignright" style="width: 310px"><img src="http://www.timespub.tc/wp-content/uploads/2011/01/H3A-Octopus-spreads-out-300x207.jpg" alt="Caribbean octopus hunts its prey at night" title="H3A---Octopus-spreads-out" width="300" height="207" class="size-medium wp-image-1902" /><p class="wp-caption-text">Caribbean octopus hunts its prey at night</p></div>One of the things that’s so different about diving at night — aside from the obvious fact that the only light comes from your torch — is that your attention becomes focused on the objects in your beam of light. Fewer distractions makes it easier to concentrate on the wonders of the individual and the minuscule — like a rare orange-ball corallimorph or a tiny decorator crab perched on a soft coral, or the delicate tentacles of an orange cup coral — as Barbara did in the photos that accompany this story.<br />
	<div id="attachment_1903" class="wp-caption alignleft" style="width: 310px"><img src="http://www.timespub.tc/wp-content/uploads/2011/01/H6-Golden-Crinoid-Walks-A-300x211.jpg" alt="Rare photo of Golden Crinoid walking at night along a vertical wall" title="H6---Golden-Crinoid-Walks-A" width="300" height="211" class="size-medium wp-image-1903" /><p class="wp-caption-text">Rare photo of Golden Crinoid walking at night along a vertical wall</p></div>At night, under the color-correcting light of a dive torch, hues appear brighter and more vibrant. That&#8217;s because during the day, the ambient light filters out the brighter colors as they penetrate increasing depths of water. As  divers, we learn that underwater, we “lose” colors according to the Roy G. Biv spectrum, meaning red is the first go. (If you’ve ever pricked your finger underwater, you’ve probably noticed that your blood looks green.) Thanks to Barbara&#8217;s strobe, the red encrusting sponge seen on page 63 is appreciably more impressive-looking than it would be in ambient light; ditto colorful regal slipper lobster on page 61.<br />
	<div id="attachment_1904" class="wp-caption alignright" style="width: 310px"><img src="http://www.timespub.tc/wp-content/uploads/2011/01/H5-Channel-Clinging-Crab-300x186.jpg" alt="Channel Clinging crab munching on dinner in spite of diver&#039;s light" title="H5---Channel-Clinging-Crab" width="300" height="186" class="size-medium wp-image-1904" /><p class="wp-caption-text">Channel Clinging crab munching on dinner in spite of diver's light</p></div>But night photography has its challenges, as Barbara has experienced time and again. Lights attracts tiny krill by the hundreds and they will bounce off your hand as they jockey for a spot close to the light source. Barbara likes to tell about the time she pointed her beam directly at the center of a giant basket star, a critter with arms that stretch a foot or more in every direction. “It’s a heady experience to behold a swarm of krill invading your light as the basket star goes into a feeding frenzy, waving and curling its tentacle in an attempt to corral the krill into its &#8216;mouth,&#8217;” she says. “You almost don’t know where to point the camera.”<br />
	Observing the reef at night teaches us things we’d never learn if we only dived during bank hours. I was amazed to witness, for instance, about the “shift change” that happens as the light of the sun begins to fade. The half hour or so between light and dark is called “quiet time,” and it’s like trying to hail a cab in Manhattan at 4 PM, just as all the drivers are heading home. There&#8217;s next to no activity on the reef. But wait! Soon a whole new crew comes on-duty, as the brightly colored diurnal fish turn in for the night. If you don’t know what to expect, you’re in for a real treat, as Barbara was the first time she encountered feathery crinoid at night. She’d been seeing them for years, waving their tentacles out from under the edges of corals and sponges, and she naturally assumed they were anchored in that spot for all eternity. Then one night she did a dive along a vertical drop off Grand Turk and spotted a golden crinoid strolling along the wall!<br />
	Another discovery that always excites visitors to the nighttime reef is the unique sleeping environment of the parrotfish. This perennial favorite excretes a mucus bubble in which they tuck themselves, cocoonlike, to sleep. This mucus “sheath” not only protects the fish from predators by shielding its scent, but it also serves as an early-warning system when a predator approaches. (And now some researchers believe that the parrotfish’s mucus has antibiotic properties that help repair bodily damage.)<br />
	Similar but different — Barbara and I have both heard that dawn is also an incredible time to dive. The night shift is packing it in, and the early birds are just waking, ready to begin another busy day on the reef. From all descriptions, it sounds like a magical time to be down there. (In fact, we’ve talked about doing this together for a future article.) But if there’s one thing divers treasure — because the trip could be our only real vacation of the year —is staying cocooned in our own little mucus bubbles as long as we can. Let’s just say it’s on the docket, and although Barbara insists I answer, “Don’t hold your breath.”</p>

Story By Suzanne Gerber ~ Photos By Barbara Shively</p>
<p>	I would have liked the job of being the person to give fish their names. Yet I doubt I could have come up with such a terrific roster of appellations, ranging from the playful (clownfish) to inspiring (stargazer) to humorous (oldwife) to poetic (barramundi) to romantic (kissing gourami) to downright confusing (spiny dogfish?!).<br />
	<div id="attachment_1806" class="wp-caption alignleft" style="width: 310px"><img src="http://www.timespub.tc/wp-content/uploads/2010/10/A4-2-LongspineSquirrelfishC-300x204.jpg" alt="Longspine squirrelfish" title="A4-2-LongspineSquirrelfishC" width="300" height="204" class="size-medium wp-image-1806" /><p class="wp-caption-text">Longspine squirrelfish</p></div>Some fish names, of course, are just plain obvious. Take the subject of this column: Big-eyed red fish. Into that popular grouping fall squirrelfish, soldierfish and cardinalfish. (And you don’t have to meet me in St. Louie to figure out how that last fellow got named.)</p>
<p>	Diving and snorkeling in the pristine waters surrounding the Turks &#038; Caicos Islands, you can’t help but notice the hundreds — maybe thousands — of, well, big-eyed red fish congregating in small to largish schools on most reefs. There are scores of species of Cardinalfish, most of which hide out in shallow reef areas ranging from four feet in depth to well over 100. A few species live synergistically with tube sponges and anemones. You wouldn’t guess it from Barbara’s terrific close-ups, but these little creatures (measuring just one to three inches) are not usually approachable by humans. When they feel threatened, they beat a hasty retreat under rocks and into crevices. But they’re not always so discriminating. One species is known to take cover inside of conch shells—often with the owner still inside.<br />
	Ranging in hue from brilliant red to light pink (and occasionally greenish, yellow-brown and silver), the Cardinalfish may stand out like a sore thumb to us, but his nocturnal nature is part of his intelligent design. In low light, he’s practically invisible to other fish (who don’t see the full spectrum we see). Conversely, his large eyes give him a competitive edge on his rivals in seeking out the tiny fish and crustaceans he so adores.<br />
	<div id="attachment_1807" class="wp-caption alignright" style="width: 310px"><img src="http://www.timespub.tc/wp-content/uploads/2010/10/A3-SquirrelfishCMYK-300x213.jpg" alt="Squirrelfish" title="A3-SquirrelfishCMYK" width="300" height="213" class="size-medium wp-image-1807" /><p class="wp-caption-text">Squirrelfish</p></div>Another interesting tidbit about the large-eyed, short-snouted Cardinalfish is their style of reproduction. These critters are mouth brooders, meaning that once the eggs are released and fertilized, usually the male will store them in his mouth to incubate, often carrying them until they’ve hatched. During this time, an expectant papa will often forego food for up to two weeks — and let mama take on the warrior role of fighting off aggressors.<br />
	It’s not just fans of Rocky and Bullwinkle who love Squirrelfish. These bug-eyed red fish are considerably larger than their Cardinal cousins, measuring between 12 and 24 inches. Counterintuitive as it might sound, their bright red color (often marked with yellow, white or black spots) serves as camouflage to help them blend in with the bold colors of the coral reef. Some Squirrelfish have stripes, rough scales and sharp spines. Their eyes resemble a squirrel’s, and their long rear dorsal fin protrudes upward, much like its terrestrial namesake.<br />
	Like Cardinalfish, Squirrelfish are nocturnal, preferring to chill out underneath rocky surfaces in the reef during daylight hours. But at night, it’s a whole different ballgame: they fan out over the reef to forage for dinner, sometimes diving more than 500 feet in their quest.<br />
	<div id="attachment_1808" class="wp-caption alignleft" style="width: 310px"><img src="http://www.timespub.tc/wp-content/uploads/2010/10/A6-BlackbarSoldierfishCMYK-300x225.jpg" alt="Blackbar Soldierfish" title="A6-BlackbarSoldierfishCMYK" width="300" height="225" class="size-medium wp-image-1808" /><p class="wp-caption-text">Blackbar Soldierfish</p></div>An interesting factoid about Squirrelfish: they are famous (well, in some circles) for their special talent to produce grunting and clicking sounds, which they make by vibrating their swim bladders. This isn’t just for the entertainment of their classmates: researchers suspect this is a defensive behavior. One species, the Longspine Squirrelfish, makes different sounds depending on the kind of threat it’s under. For example, he will emit a single grunt when waging battle with a fish that he believes he can beat. And yet when he takes on a foe that’s too big to intimidate, the Longspine will produce a series of clicking noises, believed to be the signal for, “Let’s get the heck out of here!”</p>

			<content:encoded><![CDATA[<p><strong>Middle Caicos grits have a long and distinquished ancestry.</strong><br />
By Bill Keegan</p>
<p><em>In Hispaniola both Indians and Spaniards have two kinds of bread.<br />
One sort is made of maíz, which is a grain, and the other of cassava.<br />
Maize is grain that is borne on an ear about six to eight inches long.<br />
This ear or spike is covered with grains almost as large as chickpeas.</em><br />
Gonzalo Fernández de Oviedo, 1526</p>
<p>When I first met Simon Forbes he was dancing to scratched Reggae and Calypso records at Emanuel Hall’s store in Bambarra. And man, can that man dance! In those days, Hall had one of the few stand-alone generators on the island. It may seem surprising, but electricity didn’t arrive on Middle Caicos until the early 1980s — (a fact that fuels romanticized archaeological remembrances of working at night by kerosene lantern.)</p>
<p>Simon would never claim to be of Taíno descent. So what could my research possibly have to do with him? What does Simon’s dancing have to do with global climate change? And why eat the grits? Simply stated, what most fascinates me is tracing historical connections; teasing out those aspects of the past that have created the present, and are likely to influence the future.</p>
<p><div id="attachment_1689" class="wp-caption alignleft" style="width: 309px"><img src="http://www.timespub.tc/wp-content/uploads/2010/06/maize-field-Haiti-299x201.jpg" alt="Legacy maize field near Bas Limbe, Haiti" title="maize-field-Haiti" width="299" height="201" class="size-medium wp-image-1689" /><p class="wp-caption-text">Legacy maize field near Bas Limbe, Haiti</p></div>The next time I saw Simon we were excavating a Lucayan Taíno site in a field near “Snapper Grass” next to Farm Creek Pond on the north coast of Middle Caicos (MC-32). It is a kilometer walk from Bambarra Landing to the site, and there were no farm plots (sometimes called “casual cultivation” on the topographic maps) until you reach the archaeological site. Simon was very gracious in allowing us to work in his garden, and he extolled the virtues of the land and the fabulous produce that he was able to grow there.</p>
<p>The reason that this particular plot of land was so productive is because the original inhabitants of the island lived there for about 200 years (circa AD 1300–1500) and their refuse (garbage, night soils, etc.) had greatly enriched the fertility of the otherwise sandy soil (called “whitelands” due to its light color and lack of fertility). The site has over a meter of very dark, organically enriched soil (along with artifacts from the original inhabitants) that extends to a depth of over one meter. Although it may be hard to envision, there is a definite connection between the remote past and the present. On other islands, Mayaguana for example, we have found that the “native” vegetation is far more luxuriant on Indian sites. Furthermore, throughout the Turks &#038; Caicos, Shaun Sullivan found that archaeological sites are almost always found in Guinea grass patches (a grass introduced from Africa as cattle fodder) because this grass pioneers disturbed (formerly agricultural) landscapes. In essence, the modern landscape is the product of human activities going back thousands of years.</p>
<p>The historical thread is that the land Simon farmed was superior to the surrounding whitelands because the garbage of native peoples had enriched the soil. In addition, it was Amerindians who first cultivated many of his crops. This is a classic example of how much of what we do today is a legacy of the past. About 20 years ago the Florida Museum of Natural History developed a museum exhibit called “Better than Gold.” The point was that Amerindian plants transformed European cultures in more profound ways than did shiny metal.</p>
<p>Maize (<em>Zea mays</em>) is perhaps the most important crop in history. The British called it “Indian” or “Guinea” corn because the word corn means “small bit.” The Taínos called it maíz. The ancestors of maize are apparently wild grains related to teosinte and tripsacum, with small ears the size of a person’s thumb. It is possible that modern corn developed when humans carried this grain south from Mexico into Central and Andean South America where those related species crossbred. Cobs found in caves inhabited by people southeast of Mexico City date to 5,000 BC. Recent evidence from the study of pollen, phytoliths and starch grains suggests that humans in Central America began managing maize up to 10,000 years ago, and that it was brought into the Caribbean islands about 4,000 years ago.</p>
<p>The early races did not look much like modern varieties, and it may seem odd that people focused their attention on a plant that produced a small number of grains that required special collection methods and processing. Yet we now know that a wide variety of small-seeded grains (including wheat, rice, millet, sorghum, chenopodium, and amaranth) were cultivated at early dates to supplement what were otherwise foraging economies (more popularly known as hunter-gatherers). In the early variety of maize each kernel was covered by a cupule so it was necessary to winnow the collected seed to remove this inedible covering.  Through human manipulation the kernels eventually became “naked” with only a surrounding husk.</p>
<p>Despite its humble beginnings, maize has transformed our world. When you go to the cinema or watch a movie at home you must eat popcorn. High fructose corn syrup is used to sweeten foods and soft drinks, and along with the corn oil used to fry foods, are major contributors to obesity. When you put gasoline in your car, up to 10% is ethanol distilled from maize. The steaks you just grilled are probably corn-fed beef, and cattle are significant contributors to global warming (methane). Cornstarch and corn meal are used to produce a wide variety of products, and maize agriculture receives billions of tax dollars in subsidies from the U.S. government every year. Maize can produce incredible yields per acre, but also requires enormous inputs of water (irrigation), fertilizer (nitrates) and pesticides, all of which degrade our environment. Moreover, maize yields were increased by creating a sterile hybrid, so farmers must buy their seed every year from the companies that hold the patents. In sum, maize has become the perfect storm.</p>
<p>We cannot blame the crop for its unintended consequences. Few plants have been so amenable to human manipulation. Maize now serves a vast number of purposes, is grown in a wide variety of environments, comes in a bewildering number of colors (check out blue corn tortilla chips), and is a component of almost everything we eat, drink or drive. Moreover, it has even been converted to entertainment. Because it can be grown at such a high density, corn mazes, more properly maize mazes, have become hugely popular during the Halloween season.</p>
<p>There are more than 300 races of maize. The plants range in size from two to twenty feet tall, with eight to 48 leaves, one to fifteen stalks from a single seed, and ears that range from thumb-sized to two feet in length. The basic classification recognizes “dents” with a softer kernel (95% of all maize), “flints” with a hard starch, “sweet” with a higher sugar content, “floury” with soft and mealy starch, “waxy” composed entirely of amelopectin, and “pop” which is a very hard flint — the water in the starch steam-pressures the endosperm to explode when heated.</p>
<p>Maize is a highly nutritious food, and contains more protein than any other cultigen. It has essentially the same nutritional content as breast milk, and has long served as a weaning food. It contributed to the rapid growth of human populations throughout much of the Americas, and was the staple crop for the Maya and Aztec. The one missing amino acid is lysine, which is found in beans. In Mexico, at the time of the European invasion, most gardens contained the perfect food combination; the “three Mary’s”:  corn (maíz), beans and squash.</p>
<p>In the past, maize was people food. Today, nearly 80% of the harvest goes to feed cattle and fuel automobiles. Both of these uses have contributed substantially to global warming. Boy and girl cows have stomachs that evolved to digest grasses. You can feed them corn, and they will mature faster and she produces more milk, but they cannot completely digest the proteins in maize. The resulting “cow patties” are loaded with methane gas. Methane is the most egregious of greenhouse gasses, and cattle, not cars, are the main contributor to global warming. Maybe we should follow the advice of Chick-Fil-A and “eat mor chiken” (but this raises a whole number of other issues). In addition, the U.S. government has promoted the use of ethanol as an alternative fuel for cars, and corn growers now benefit from a number of subsidies. Yet, ethanol is a far less efficient fuel than gasoline, and the quantities of water, fertilizer, fuel for farm vehicles and the processing required to produce this fuel have never been fully disclosed. The use of ethanol may actually contribute to global warming. And recent commentaries have asked whether we should grow corn to feed cars or to feed people?</p>
<p>Enough gloom and doom; there is nothing quite like the original product. While conducting a survey of North Caicos years ago, our local guide stopped in his family farm and roasted several ears of corn on an open fire. When I peeled back the husk I found that several rows had popped. This was the only time I was ever treated to popcorn on the cob! Had this corn been allowed to fully ripen it would have been ground into the porridge that we call grits.</p>
<p>There are only a few places in the world where you can still get “legacy” corn. Middle and North Caicos are two of those places (we have colleagues doing DNA studies to trace the heritage). There is a world of difference in taste and nutritional value between legacy and modern varieties. We suggest you be a “locavore” (eat locally grown foods). Visit Daniel’s Café in Conch Bar, Middle Caicos, for a traditional grits breakfast on Saturdays, or buy these locally grown and hand-ground grits at the Middle Caicos Co-op on the second Saturday of each month at the Graceway Supermarket in Provo. You will experience a unique connection to the past, not to mention that there is nothing quite as tasty as Middle Caicos grits.</p>

<p><strong>Middle Caicos Grits</strong></p>
<p>Landscaping is an almost unknown term in Middle Caicos, but small “farms” are found throughout the island where crops of cassava, okra, sweet potato, pigeon peas and corn still flourish. Home is where the heart is when it comes to Caicos corn . . . it is a beloved treat at all stages with new corn roasted on open fires and the favourful local grits sparking up all kinds of home cooking.</p>
<p><div id="attachment_1690" class="wp-caption alignright" style="width: 310px"><img src="http://www.timespub.tc/wp-content/uploads/2010/06/Grits-preparation-300x225.jpg" alt="North Caicos kitchen" title="Grits-preparation" width="300" height="225" class="size-medium wp-image-1690" /><p class="wp-caption-text">North Caicos kitchen</p></div>The pearly kernels dry hard on the stalk in the field; then the ears are carried home to be stored in the roof until time to grind. The kernels are stripped from the cob, ground with hand grinders (once for coarse, twice for a fine grind) and then the laborious process of “fanning” the grits to release the chaff begins. Fanning involves the use of a specially made shallow rim basket, locally known as a fanner basket, and made with fanner grass! In this basket, the grits are tossed and turned, with the lighter chaff blowing away in the breeze. Amazingly, the process ends with corn flour on one side of the basket, and bright coloured yellow grits on the other.</p>
<p>Once cleaned and fanned, the grits are kept cool and fresh, ready to purchase at the Conch Bar Artisan Studio &#038; Outlet. Local chefs use these grits to the delight of patrons. Daniel Forbes’ special, at Daniel’s Café in Middle Caicos is Conch and Grits, a treat that brings the flavor of the ocean to this simple dish. In a world of fast food, these wonderful grits, a labour of love and time, offer a taste sensation that is long remembered.</p>
<p><strong>Miss Joycelyn’s Plain Grits Recipe</strong></p>
<p>Use 3 cups water, salt to taste, 2 teaspoons butter, and 1 cup grits. Put water, salt and butter in medium pot and bring to a full boil. Add grits and stir thoroughly. Cover and cook over medium heat for 15 – 20 minutes. Check grits after 10 minutes – if too stiff, add more water (¼ cup – ½ cup). When cooked grits will be smooth and even. Serve as a side dish with more butter, salt and pepper.</p>
<p>Popular local options:  Cook local beans, fry with butter and onion, and add to grits while cooking or chop and wash salt beef and add to pot with water, then boil with grits.</p>

			<content:encoded><![CDATA[<p><strong>Multi-hued sea anemones turn the coral reef into an underwater garden.</strong></p>

<p>No, you’re not confused: There are anemones in your garden, and there are sea anemones in the ocean. In fact, the ornately colored sea anemone (uh-NEM-uh-nee) is so called because of the striking resemblance it bears to its colorful terrestrial namesake.</p>
<p>As beautiful and delicate as they may be, anemones are actually highly poisonous predatory creatures. These marine animals, which attach to rocks or corals by an adhesive pedal disc, or foot, spend most of their life laying in wait for unsuspecting fish to swim close enough to get ensnared in their venom-filled tentacles. Of the 1,000 species of anemones found in shallow coastal waters (and occasionally in deeper water) across the globe, a handful has the ability to move — though they’ll never set any speed records. At best they can travel four inches an hour. Some creep along on their suction foot. Others appear to be somersaulting. Still others locomote by flexing their bodies. </p>
<p>Watching them in motion can be fun. Barbara recalls seeing a golden crinoid traversing the side of a nearly vertical wall one night last summer on Grand Turk. “I knew anemones could move,” she says, “but I didn’t realize they could change neighborhoods!”</p>
<p><div id="attachment_1724" class="wp-caption alignleft" style="width: 250px"><img src="http://www.timespub.tc/wp-content/uploads/2010/06/Anemone-Vertical-240x300.jpg" alt="Giant anemone on Turks &amp; Caicos reef" title="Anemone-Vertical" width="240" height="300" class="size-medium wp-image-1724" /><p class="wp-caption-text">Giant anemone on Turks &#038; Caicos reef</p></div>Famous for symbiotic relationships, the clever anemone sometimes catches a lift from a passing hermit or decorator crab, who appreciates the camouflage covering the anemone provides (as well as protection from crafty octopi, who love to feast on crab). The anemone benefits not only with a speeder ride, but he often gets lucky and catches falling pieces of food that the sloppy crab doesn’t quite manage to polish off.</p>
<p>Sea anemones come in all sizes, shapes and colors, but in the waters surrounding the TCI, we tend to see the tubular-tentacled species that Barbara has so beautifully captured for this story. The tentacles serve two purposes. Not only do they protect the animal, but they are what it uses to catch food. Those undulating “fingers” that we divers and snorkelers admire from a distance are studded with microscopic stinging capsules (called nematocysts), and at the slightest touch or provocation will eject a harpoon-like filament that paralyzes its prey with a poisonous neurotoxin. (This is what gives the anemone that sticky feeling.) Favorite victims — er, meals — include fish, mussels, zooplankton, shrimp and worms. On the flip side of the food chain, sea anemones have very few predators themselves: mostly just nudibranchs, snails, sea stars and certain fish, like the Tompot Blenny.</p>
<p><div id="attachment_1725" class="wp-caption alignright" style="width: 310px"><img src="http://www.timespub.tc/wp-content/uploads/2010/06/AnemoneGreen-300x215.jpg" alt="Green-tipped giant anemone on Turks &amp; Caicos reef" title="AnemoneGreen" width="300" height="215" class="size-medium wp-image-1725" /><p class="wp-caption-text">Green-tipped giant anemone on Turks &#038; Caicos reef</p></div>Sometimes anemones reproduce simply by dividing in two, with each half forming a new animal (an act called lateral fission) or by “budding off” baby sea anemones. But sea anemones occasionally enjoy an exciting sex life. In addition to the fission method, they also engage in sexual reproduction and release eggs and sperm through their “mouths” that produce free-swimming larvae, which will eventually settle and grow into a single polyp. Like many other marine creatures, some anemones are distinctly male, others clearly female, and some are protandric hermaphrodites (i.e., first male, then female).</p>
<p><div id="attachment_1726" class="wp-caption alignleft" style="width: 310px"><img src="http://www.timespub.tc/wp-content/uploads/2010/06/AnemoneSolidPurple-300x294.jpg" alt="Solid purple giant anemone on Turks &amp; Caicos reef" title="AnemoneSolidPurple" width="300" height="294" class="size-medium wp-image-1726" /><p class="wp-caption-text">Solid purple giant anemone on Turks &#038; Caicos reef</p></div>But it’s not all fun and games in the life of a sea anemone. The pharmaceutical industry and medical research teams are studying different ways the unique qualities of this creature can be put to use to help humans. One thing that’s being studied is how the neurotoxin emitted by the tentacles to catch prey might help certain cardiac problems. Last year British scientists began experimenting with blending the stinging threads into skin cream to produce a needle-free way of delivering insulin to diabetic patients. And most recently, researchers have extracted a fluorescent protein from a certain bright-red species of anemone that holds promise in imaging technologies. Two years ago, researchers who discovered a similar protein in a jellyfish that advanced biological imaging won the Nobel Prize for Chemistry. This could prove the most dramatic symbiotic relationship of all.</p>

<p><strong>The late Claude Lévi-Strauss dispeled the notion of “us” and “them”.</strong></p>
<p>By Bill Keegan and Betsy Carlson</p>
<p><em>I have sought a human society reduced to its most basic expression.  <span style="font-style: normal;">Claude Levi-Strauss, Triste Tropiques, 1955</span></em></p>
<p><span style="white-space: pre;"> </span>Keegan was a teaching assistant for “Introduction to Biological Anthropology” at Florida Atlantic University in 1980.  At the time the university was attempting to boost admissions by offering special tuition to the burgeoning retiree population around Boca Raton. The first day of class there were about 80 people in the room, all listening intently as the professor explained that we would be studying genetics, human evolution, and biological diversity in our species. Eventually, one of the older women in the class raised her hand and asked, “When are we going to study primitive behavior, bizarre marriage practices and mating rituals?” The professor gently explained that this was not our subject. “But I thought this was an anthropology class!” The next class had only about 20 students, and the blue hair adorned a decidedly younger audience.</p>
<div id="attachment_1606" class="wp-caption alignleft" style="width: 196px"><img class="size-medium wp-image-1606" title="Attabeira" src="http://www.timespub.tc/wp-content/uploads/2010/04/Attabeira-186x300.jpg" alt="The Taino frog goddess" width="186" height="300" /><p class="wp-caption-text">The Taino frog goddess</p></div>
<p><span style="white-space: pre;"> </span>The older crowd apparently didn’t get the memo. By this time, the French anthropologist Claude Lévi-Strauss had spent nearly 50 years attempting to dispel the notion of the “primitive mind,” and he did so by studying myths (<em>The Savage Mind</em>, 1962, University of Chicago Press).  We decided to write this essay because he was one of the most important figures in anthropology for the past century. He passed away on October 20, 2009 at the age of 100.</p>
<p><span style="white-space: pre;"> </span>The majority of Lévi-Strauss’ work focused on the stories related to him by the native peoples of the Amazonian rainforest in Brazil. When he began his field research in the 1930s, the prevailing attitude was that the primitive mind was different from our own. These simple people faced a daily struggle for survival, and therefore lacked our appreciation of logic and formal thought. There were strong paternalistic and colonialist attitudes at work, especially in the late 19th and early 20th centuries. These savages needed Western civilization to drag them into the modern era. Yet by looking just below the surface, we find that they are in every way as sophisticated intellectually, and the notion of Thomas Hobbes (<em>The Leviathan</em>, 1660) that their lives are “nasty, brutish and short” is just not correct. There is a richness in their arts that rivals our own.</p>
<p><span style="white-space: pre;"> </span>Monsieur le professeur Lévi-Strauss pioneered a philosophical approach in anthropology known as “Structuralism” (<em>Structural Anthropology</em>, 1958, Penguin Press). Structuralism proposed that there are universal structures, pairs of opposites that underlie all human thought and are common to all human societies. In other words, there is no “us” vs. “them.” there is only “us.” Because of this, Lévi-Strauss rejected the notion that so-called “primitive” peoples were any less sophisticated than us, and that their belief systems (“myths”) are the product of rational thinking and subtle logic. This may not appear to be the same logic that we use, but that is because our interpretations often are based on superficial characteristics of which we have little direct knowledge.</p>
<p><span style="white-space: pre;"> </span>The instances of universal structures seem to far outweigh the notion that all people think differently (especially “primitive” people). Is not the Taíno origin story in which the human hero (<em>Deminán</em>) stole yucca and fishes (human foods) from the supreme deity (<em>Yaya</em>) repeated in most mythologies? We are very fortunate that Christopher Columbus sent the Jeronomite friar Ramón Pané to study the religion of the Macorix peoples who lived on the north coast of Hispaniola. Pané’s account has been taken as representative of all Taíno beliefs. These myths have been interpreted using Structuralist principles (see <em>Cave of the Jagua</em>, Antonio Stevens-Arroyo, 2006, University of Scranton Press).</p>
<p><span style="white-space: pre;"> </span>One aspect of Structuralism deals with “totemism,” in which human social groups identify themselves by certain animals (think sports teams). A favorite saying attributed to Lévi-Strauss with regard to animals is that “some animals are good to think, while others are good to eat.” Taíno beliefs are replete with imagery and stories that capture animals that “are good to think. Macocel, a lizard whose eyes did not blink, guarded the cave from which humans emerged in Taíno mythology. A supreme Taíno deity is <em>Anacaona</em> — the “frog-lady” — and the frog, which is a symbol of female fertility, is pervasive in Taíno decorative arts.</p>
<p><span style="white-space: pre;"> </span>We recognize a three-part division of the Taíno world into sky, land and subterranean waters. Creatures and features that bridge these realms are given particular importance in the mythology. Thus, seabirds that pass from sky to land and water (e.g., pelicans), reptiles that pass from water to land (e.g., sea turtles), and caves that form a portal from the land to subterranean waters all figure prominently. According to the Taínos, the first humans emerged from caves, and often were returned there at death. The three realms of sky, land and water are united by an invisible “tree of life” that springs forth as the axis mundi in the center of the village.</p>
<p><span style="white-space: pre;"> </span></p>
<div id="attachment_1607" class="wp-caption alignright" style="width: 310px"><img class="size-medium wp-image-1607" title="Turtle duho" src="http://www.timespub.tc/wp-content/uploads/2010/04/duho-300x198.jpg" alt="Wooden seat shaped like sea turtle" width="300" height="198" /><p class="wp-caption-text">Wooden seat shaped like sea turtle</p></div>
<p>Lévi-Strauss recognized that the way that a village was arranged could hold clues to human consciousness. The circular arrangement of Taíno villages can be likened to the ripples on a pond; the central plaza is a charged political space, the surrounding houses (<em>caneye</em>) are a closed domestic space, the adjacent fields (<em>conuco</em>) represent man’s control over nature, and the encompassing forest (<em>abeybuco</em>) is the non-cultural world of nature and at night the domain of the spirits (<em>opía</em>).</p>
<p><span style="white-space: pre;"> </span>The archaeologists who excavated the Golden Rock site on St. Eustatius in the Lesser Antilles (circa AD 900) noted very distinctive stains in the ground that outlined the structure of the houses. They concluded that the houses were shaped to look like the carapace of a sea turtle, which fits with the symbolic identity of turtles with life.  Such interpretations may at times seem fanciful, but they add to the richness in interpretation proposed for past societies.</p>
<p><span style="white-space: pre;"> </span>In later life Lévi-Strauss argued that music had largely replaced mythology in the modern world. Music tells the same stories and we enjoy hearing them over and over again. The story is reinforced by a repeating melody and harmonics, and everyone knows that it is time to get out of the water when Dvorak’s first symphony starts to play (the theme music from the movie “Jaws”). We see, read and hear the same themes (structures) repeated in cinema, books, and music, and often these are very basic human constructs:  good vs. evil, life vs. death, love vs. hate, nature vs. culture (this last dichotomy was described in Lévi-Straussian terminology as “raw” vs. “cooked”). The image can be as subtle as who is wearing the white hat, and the passages are often decidedly predictable — the action hero always gets beat to a pulp, and is on the verge of death, before overcoming their antagonist in the final scene.</p>
<p><span style="white-space: pre;"> </span>Lévi-Strauss’ critics claimed that he did not pay enough attention to local history and experience. Their “poststructuralism” rejected the idea that universal laws were what shaped human consciousness. His reply would be that much of what we think is subconscious. But even his critics admit that there are underlying structures to all art. A notable recent example is <em>The Da Vinci Code</em> (Dan Brown, 2003, Doubleday). The key is finding the hidden messages, and having the skills to interpret them. What we hope is that there are sufficient similarities between us and them (structuralism), that we can detect the underlying meanings as they intended or subconsciously transmitted according to their particular representational system (poststructuralism).</p>
<p><span style="white-space: pre;"> </span>So let us pause for the moment and mark the passing of one of the greatest intellectuals of the 20th century. A man who was equally comfortable in the ivory tower and in the Brazilian rainforest. In our Western religious traditions death marks a transition of “ashes to ashes, dust to dust.” Although Lévi-Strauss has passed to ashes, he left us the honey.</p>

<p><strong>The large, colorful, sociable Angelfish is on the “A” list in fish popularity.</strong></p>

<p>When your dive or snorkeling buddy draws an imaginary ring over his head, he’s not telling you that he’s lost — or gone cuckoo. He’s signaling one of the most popular reef fish in the ocean, the flamboyant angelfish. Some fish master the art of camouflage for protection; if angelfish had to rely on that trick to survive, they’d be dead fast. With their bright, vibrant color patterns and big, round, skinny bodies, they’re among the most delightfully conspicuous residents of the coral reef. Found throughout the Caribbean, Atlantic, Indian, and Pacific oceans, they are also one of the most popular among underwater visitors of every nationality. And because they’re approachable, photogenic, and often curious about us, Barbara and I often find ourselves hot on their trail.</p>

<p><span style="white-space: pre;"> </span>Here in the Caribbean we are most familiar with six varieties — the Queen, Blue, Gray, Pygmy and French Angelfish, as well as the dramatic black-and-yellow Rock Beauty — yet there are 75 to 85 different species in the rest of the world. When I first started diving the western Pacific and Indian oceans and compiled a “fish wish list,” at least five of my most-sought-after critters were exotic and stunning angels, like the Emperor.</p>
<p><span style="white-space: pre;"> </span>It’s easy to spot most varieties of Angelfish: they’re basically round in appearance (sometimes playfully described as pancake-like), with eyes that seem to see, register and follow us. And most have small but full, almost puckered lips, often painted a prominent gray or white.</p>
<p><span style="white-space: pre;"> </span>Why are they called Angels? I’ve heard a few explanations: The ring on some species’ heads resembles a halo; their fins spread in all directions, like an angel’s wings; and they drift through the water in an almost heavenly way. The Queen derives her royal appellation from the blue-ringed black spot on her head that resembles a crown. They are closely related to Butterflyfish, another “flashy” reef fish with scores of varieties. But scientists distinguish Angelfish from Butterflyfish by their rough spines, which cover their gill and help explain their Greek name, <em>Pomacanthidae</em> (poma meaning &#8220;cover,&#8221; and akantha for &#8220;thorn&#8221;).</p>
<p><span style="white-space: pre;"> </span></p>
<div id="attachment_1642" class="wp-caption alignleft" style="width: 310px"><img class="size-medium wp-image-1642" title="FA2cmyk" src="http://www.timespub.tc/wp-content/uploads/2010/04/FA2cmyk-300x213.jpg" alt="French Angelfish" width="300" height="213" /><p class="wp-caption-text">French Angelfish</p></div>
<p>The three Caribbean species have some similarities, as well as distinct differences. Pygmy Angels, as you’d likely guess, are the smallest, averaging just three inches, and the largest specimens, the French and Gray, can be up to 24 inches. The Pygmy, also called the Cherubfish, is deep blue in color with pale yellow fins and is the rarest in these waters because they live in considerably deeper quarters than their larger cousins. The regal Queen, who can grow up to 18 inches, is usually an intense blue with yellow markings on her fins and that black and blue spot on the top of her head. She is always just begging for a photo op. Blue Angelfish looks a lot like Queens but are a lighter shade of blue and yellow and don’t have the “crown.” (But they are uppity, frequently mating with Queens.) The Gray Angelfish is indeed gray, with yellow fins. People sometimes confused Grays with French Angelfish, who looks like someone hit the color-enhancer button and painted the drab Gray a much deeper shade of black and added more hue to his yellow scale tips and the yellow around its eye. And then, in the “which of these things is not like the other” category, there’s the sweet Rock Beauty: black with a yellow head, chest and underbelly. Not only does she look markedly different, but her behavior stands out in contrast: where the French, Gray, Blue and Queen have been called everything from friendly and fearless to pests and hams, the Rock Beauty is adorably shy (though when they curl their bodies around a crack in the reef and face you, they make fantastic photos!).</p>
<p><span style="white-space: pre;"> </span>Angelfish normally form pairs or small groups. Some mate for life; others form “harems,” with one male presiding over several females. And as with many fish species, Angelfish are hermaphrodites, and if the dominant male of a harem is removed, one of the “wives” will morph into a functional male to take his place.</p>
<p><span style="white-space: pre;"> </span>Terrific munchers — you can actually hear them chomping in the water — Angels enjoy a diverse diet, at least by fish standards. They dine on sponges, algae, small crustaceans, sea fans, soft corals, and even the occasional unlucky jellyfish. Mostly, though, they prefer sponges, a menu selection that is fairly uncommon for fish (as opposed to turtles), owing to sponges’ indigestible innards and nasty-tasting outside layer. Perhaps as an adaptive measure, Angelfish have evolved a protracted jaw with specialized teeth as well as the talent to secrete a thick mucus coating around bits of sponge. This ability gives them an edge in the highly competitive eco-system.</p>
<p><span style="white-space: pre;"> </span></p>
<div id="attachment_1643" class="wp-caption alignright" style="width: 310px"><img class="size-medium wp-image-1643" title="GA2cmyk" src="http://www.timespub.tc/wp-content/uploads/2010/04/GA2cmyk-300x222.jpg" alt="Gray Angelfish" width="300" height="222" /><p class="wp-caption-text">Gray Angelfish</p></div>
<p>In the Caribbean, French Angelfish (Pomacanthus paru) are favorites among snorkelers and divers, both for their good looks and great personality. They, too, feed mainly on sponges, as well as the occasional gorgonian, tunicate and algae. Divers get a kick out of watching them as they take deep gouges out of sponges, leaving V-shaped scars with their rabbit-like teeth. On the flip side of the food chain, their large size, as well as their ability to dart defensively into narrow crevices, prevents all but the largest reef predators, like big grouper and sharks, from attacking.</p>
<p><span style="white-space: pre;"> </span>Frenchies mate for life, and together the fiercely territorial pair will patrol their turf, which can be an area as big as a football field. Potential space invaders are chased off by an enraged Frenchie. It’s a sight to behold, as the fish leans to one side and charges like a tipsy bull. The couple spends half their time foraging for food and the other half “carouseling” — circling each other head to tail, an act that both resolidifies their bond after time apart and wards off couple-busting rogue bachelors. Though they are admirably monogamous, Frenchies aren’t overly romantic. Their mating ritual is anything but flirtatious: toward dusk during mating season (April to September, usually peaking in July), they form an arc and rise up in the water column, pressing their bellies together until they reach an angelic climax, at which time sperm and between 25,000 and 75,000 eggs are released. Many won’t make it, however, because of many plankton-munching predators.</p>
<p><span style="white-space: pre;"> </span>Juveniles who do survive are put to work early, working in cleaning stations. Young’uns attract clients by setting up shop at prominent outcroppings, small patch reefs, or depressions in a rocky area. They let other fish know they’re open for business by wriggling their brightly colored bodies like a flag and either hovering just above the reef or settling onto it. The juvies’ job is to inspect their clients for parasites and then remove them by eating them. It makes for compelling video to capture fish waiting in turn for their cleaning, like the line at the carwash on the first warm spring day. Occasionally fish-fights break out over who’s where in the queue, so keep your camera at the ready.</p>
<p><span style="white-space: pre;"> </span>While it is a universal underwater hand sign to indicate Angelfish with the “halo” signal mentioned earlier, I came up with my own sign for Frenchies a number of years ago. A beautiful pair was carouseling just outside my buddy’s periphery, and my halo signal wasn’t doing the trick, probably because he was looking for the blue and yellow glow of a Queen. Thinking fast, I pressed my index and middle fingers to my lips, waved them away, blew out through my regulator, then returned my fingers to my mouth and flicked them again. Back on the boat, I asked him if he saw those two big Frenchies. “I did,” he said, “but what in the world was that hand signal?” “Well,” I responded, “there’s no sign for French Angelfish, so I invented one: I was smoking.” He thought I was nuts, but to this day, we use that same sign when we as a couple bump into a couple of them.</p>
