Cozumel Underwater 3 Now we're on the first night dive. A "Giant Crab" Mithrax (?) related to northern Spider Crabs. Mr Crab again. Yellow Stingray Urolophus jamaicensis A sleeping Stoplight Parrotfish Sparisoma viride Slipper Lobster Scyllarides nodifer orSculptured Slipper Lobster Parribacus antarcticus No claws, no spines, no teeth, no camouflage. No fangs, no barbs, no bristles, no poison. No strength, no speed, no brains. You really have to wonder how they survive. Common Atlantic Octopus Octopus vulgaris Obviously not pleased to see me.

I still don't understand why people dive in holes. Mostly French Grunts Haemulon flavolineatum Another crab, oddly out in the open during the day. French Angelfish.
