The 'Long-Horn' aeolid from Belize

The Long-Horn Nudibranchs are another species I photographed in Belize [western Caribbean] last month. They were 1/2 to 1 inch long! We have them in Florida but they are about 1/4 inch long here.

Dear Anne,
As with the last photos you sent me I don't know this species either, and I don't have Paul Humann's book. It looks like a species of Phidiana or something similar. Since we had instant success with your last photo, I'm sure we won't have to wait long for some more information on this one.

It certainly illustrates how poor the literature on the West Atlantic fauna is. As far as the Caribbean fauna is concerned the greater part of the scientific literature consists of Marcus's papers describing preserved animals. Apart from the recent message from Phanor Montoya in Colombia, I have had a number of messages from students in Latin America who would like to study nudibranchs and find it impossible to identify even the most common species. Are there any good books I don't know about? If not, I am happy to post photos of West Atlantic species. Obviously I would need help with photos and some background information.
Bill Rudman.
