Charlotte and I took a small vacation to the southern Bahamas. I photographed this nudibranch. Can you identify it?

Dear paul,
This is an interesting find. I am pretty sure it is Hypselodoris nyalya. Unfortunately the original description, by Marcus, is based on 2 preserved animals from Florida. The one colour photo shows a fairly dark blue animal and a red mantle border. Another photo (Humann, 1992) also shows a dark blue animal but the border appears to be multicoloured - red on the outside then yellow orange, and white on the inside. I think your animal is a pale version of that.

I only know of these two previous records of the species.
Best wishes,
Bill Rudman
