I found this on Snapper's (diving out of Key Largo). It seems to be a purple spotted sea goddess. My Depth was between 20 and 25 feet. The creature was between 1 and 1.5 inches in length. I looked it up (in Humann & Deloach) for the initial ID and posted it on the ScubaBoard. According to the book, this species is not known in Florida. Another member suggested that I notify the Sea Slug Forum. I wanted to post here as well. It may be something special. I have other shots and higher res, if you need more information.
