Hello Bill

Thought that these images of Aldisa cooperi with its eggs mass may be of value to the Forum. It may also be of interest to see the animal, not on Anthoarcuata graceae but on Scarnus erithacus.

Locality: NE Pearse, 50 feet, British Columbia, Canada, Pacific Ocean, 21 May 2007, Wall. Length: +/- 2 cm. Photographer: Jackie Hildering.

Hi Jackie,

Well, hummmm. I am not sure this is Aldisa cooperi at all. The dorsal spots are not right and we cannot see the gill well enough to be sure. Also, the eggs are certainly not. With Bill's help, I am going to guess that this is a very pale Rostanga pulchra based on the morphology of the rhinophores. Also R. pulchra often has scattered dark specks. Please remember that identifying species of nudibranchs from photos is not a perfect science.

Hope I am right,
Dave Behrens
