Have you ever been diving in St. Martin?

Exploring turtle reef

Its been a while since I was last in St. Martin, or  St. Marteen if you prefer.  It is not a place that many divers go, but it is a place that attracts a lot of yachts and super-yachts.  We were there sailing on a catamaran that was part of the Trade winds fleet.  One of my favorite dive sites on St. Martin was a place called turtle reef.  Now if you look on most maps of the island you will not find a dive site called turtle reef.  We dove with a shop called Octopus diving.  They picked us up at our boat which was anchored in Grand Cass.  They were well prepared and whisked us off to the diver sites for the days diving.

We did not have far to go. I had not even finished kitting up before we were there. The buoy marking the dive site was not much bigger than a plastic coke bottle. You would probably only find the site if you knew the gps coordinates.  After our briefing, Keith and I were ready to get in and see what the site had to offer.  

Our expectations were high that we would see a turtle.  Viz was pretty good and the site was basically a small pinnacle that rose from the surrounding depths to within 15 feet of the surface.  It was a sunny day with lots of light.  The site was full of fish life.  There were grunts galore, but for much of the dive, no turtles.  

An amazing amount of fish life

 

But towards the end of the dive the dive master spotted a turtle heading to the pinnacle from much deeper blue water.  It was a rather large hawksbill turtle and he was not at all concerned about the presence of a couple of divers.

Would I go back to turtle reef?  Of course, any day you get to dive with turtles is a good day.  

Do you have a favorite crustacean?

According to my critters book the crustaceans in the Caribbean can be divided into shrimp, lobsters and crabs. Now assuming we are just talking about seeing these critters underwater, I tend to find the variety of crabs to be the most interesting. Now that is not to say that I do not find the various lobsters to be interesting, its just the variety of crabs seems to be more diverse and that is interesting to me. There are about 45 varieties of crabs in the Caribbean. The largest of which tend to be the channel clinging crabs. I have seen them on quite a few dives in Belize, Mexico, Cayman islands and Dominica. That is not to say they do not live elsewhere in the Caribbean, they do. I just have not had the opportunity to see them.

Now, it seems to me that hermit crabs are the most common crabs I have seen. I have seen them on just about every island or islet I have visited. There appear to be about 11 varieties of hermit crab in the Caribbean, and they range in size from tiny to enormous.

When I was in Cayman Brac this year, while I was diving on a night dive I looked up under a part of a coral ledge and found a plumed hairy crab. He was very shy and very quickly after I got a shot or two of him he crawled back into his hiding hole in the reef.

Arrow crabs almost always make me laugh because they remind me of daddy long legs, but when they are hunting if they are very successful, they stick their prey on top of their heads and just keep hunting.

For me, some of the most productive dives for finding crabs, have been night dives. I guess that is not surprising since that is usually when crustaceans hunt for food. Inasmuch as it looks like I still have about 30 varieties of crab to see, I am going to have to do alot more night dives. 🙂
