The attached slides were taken in the northwestern Atlantic Ocean just off the coast of Long Island New York. The depth was about 20 feet (6 meters). There were two of these Nudibranchs in the area on hydroids. One of the shots shows their eggs. I think it is a Coryphella, but I have not been able to identify the species. The records for Northern Atlantic nudibranchs are very limited.

Rather than make a guess I will leave it to someone else to help us out. I can't really estimate its size, but if I was making a guess I would say a Cuthona or a related genus. Can someone with a knowledge of the fauna of the US east coast come to our aid please.
