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. 🙂

What are the odds?

arch-with-diver-1-of-1On the trip to Kona I did 22 dives during a week spread out over 20 dive sites.  The dive sites were sprinkled along the Kona coast over about  60 miles of coastline.  Each site had its own unique characteristics, but there were many similarities.  The hard coral for the most part looked pretty much the same.

Before each dive we would get a dive briefing and I would alway being listening to get a sense of the types of animals that we might see during the dive as well as about the reef structure and other features of the particular site. Of course, I was always trying to get a sense of whether I should rig the camera for wide-angle shooting or macro.  Many times I would ask the crew the night before whether I should rig the camera for wide-angle or macro because it takes quite a bit of time to get the camera set up if I have to change from one setting to another.

For the most part the crew was pretty good at estimating whether the next day would be good for wide-angle or macro photography.  Nevertheless, as Murphy’s law would suggest there were times where I guessed wrong.  Now shooting a small animal with a wide-angle set up is not the end of the world, it’s just frustrating.  (Kind of like being asked to hit off the golf tee with a putter or sink a put with a driver.  Yes, it can be done, because I’ve tried it, but I don’t recommend it.  For me and golf it just adds another layer of frustration to an already frustrating game.)

Shooting a macro subject with a wide-angle lens is similarly frustrating.  If you get the critter in the image you end up cropping to the point that the image ends up pretty small.  And, you rarely get the detail that I would want to see with a macro lens.  In this instance, you could count the spots on the little guy’s back.  Now he was less than an inch in length so trying to find him was just dumb luck.  Nevertheless, there he was on dive 20 and I doubt that anyone else saw him. Now of course, one of my recurring dreams is to be able to swim with and shoot whales, but with my luck it will probably be a day when I’m rigged for macro.  I will probably get a good shot of the eye and then be relegated to shooting barnacles on the whale’s back.  Oh well it would still be a good story.
