Ok - going to jump ahead because Anya requested I post this one for her...

The always beautiful Lettuce Sea Slug (Elysia crispata).

Technical Data: Canon EOS 7D, Canon EF 100mm f/2.8L Macro IS USM, 1/200th sec at f/8. Image Stabilization on. ISO 400. Ikelite Housing and Port and Ikelite 161 Strobe in TTL Mode. Raw conversion in Photoshop CS5.

I should point out that that tiny black dot under its rhinophore is its eye... now you know, and knowing is half the battle! :)

Though - to be honest, we saw many more (and more beautiful) lettuce sea slugs on our Caribbean Explorer trip (check those posts out here).
