Let's see what I can do straight from my head at 3am. Unfortunately, fish aren't my specialty, so I may bungle some of this junk.
1. Panulirus argus. Florida Spiny Lobster.
2. dang, I suck with sponges.
3. HorseEye Jacks. Caranx hippos I think. Nice shot by the way.
4. Urolophus jamaicensis. Yellow (or Jamaican) stingray
5. Caribbean long-spined urchin. Diadema antillarum. There's also some adult blue chromis (Chromis cyanea), and the little purple things with 'em might be juvenile creole wrasse, or maybe creolefish. I always get them backwards... anyway one of 'em's called Paranthias crucifer... I think.
I'm going to bed now.
