Hi Bill;

I think this is a Pleurobranchus areolatus. The upper right photo shows two of them.

Locality: Bahamas, Depth: 30 feet. Length: 3 inches. June 2002. Photographer: Keri Wilk

Dear Les,
Have a look at the messages and Fact Sheets for P. areolatus and P. atlanticus. I am pretty sure your animals are P. atlanticus. If you look at your photos you will see that scattered tubercles are larger than the others and have a heavy opaque white mark on them. It is not as obvious in your animals than most others on the Forum, but the white mark is usuall traingular in shape making these large tubercles look like a set of radiating white pointed papillae on the mantle.
Best wishes,
Bill Rudman
