Chitons are unusual creatures that cling to the rocks

Have you ever wandered through the water at low tide and checked out the rocks? For sure you’ll see these interesting looking things attached to the rocks. They are called Chitons, Coat of Mail shells or more locally by the colourful name of “suck rock”. Chitons are armoured, oval shaped creatures that live on the rocks around the tide line and basically are almost impossible to pry off the rocks.

  These animals or mollusks are characterised by eight armoured plates. The West Indian Fuzzy Chiton is medium sized and you don’t often notice them because their colour and texture is similar to the rocks on which they live and therefore they blend in. I thought the above photo was unusual because of the tiny star barnacles (also a mollusk) living on it’s back.

 

Here's a closeup of the West Indian Fuzzy Chiton showing the barnacles.

 Apparently the Lucayan Tainos used to harvest the chitons by using tools made from conch shells. They were somehow able to get the meat inside without smashing the plates. The small strip of chiton meat is salty, rubbery and a little slimy.

 

This chiton shell was found by a guest of Harbour Club Villas and it has the most beautiful markings.

If you are out exploring any of Providenciales’ rocky shoreline, stop to take a look and see if you can find these interesting mollusks.

See you on the rocks!!

Rocky Shoreline

Yesterday’s boat trip to South West Harbour Bluff at low tide gave me an opportunity to explore the rocky shore line close to the pirates cave and Osprey Rock. I took photos of these tiny shells clinging onto the rocks but it was difficult with the water flowing over.

Can you pick out the small three coloured hermit crabs peeking out from the shells?  These tiny crabs called Clibanarius Tricolor are found in tidal pools and on intertidal and subtidal rocks. They have blue legs with red stripes and I didn’t even notice this when I was taking the photos. These shells were very pretty and in the close up you can see the blue striped legs coming out of two of the shells.

Tidal rocks had clusters of shells and to my surprise, small tricoloured blue hermit crabs in them.

More neat and interesting things that I found along the undercut shore line at low tide will be posted in days to come. There are so many wonderful things to see here in the Turks and Caicos Islands…..every time you turn around there’s something new to photograph.
