Venezuelan Chromodoris binza

From: Nelsy Rivero

Hi Dr. Rudman
This nudibranch was collected under rocks from Parque Nacional Morrocoy, Venezuela. I think is Chromodoris binza, because is very similar to the picture in Angel Valdes's message. The animal 0.5 cm long.

I would like to obtained more information about this species.
Thank very much,

Dear Nelsy,
We know very little about Chromodoris binza and Chromodoris clenchi. In an earlier message, Angel Valdes seems quite convinced that C. clenchi and C. binza have quite different colour patterns and behaviour, but if you look at the photos of these two species on the Forum there do appear to be some intermediate colour patterns. As I have said about other problematic species, I think we will only resolve these identification problems when local biologists, study local populations, and compare the feeding and breeding biology, and interactions of the different colour forms. One start would be to photograph the sponge food and egg ribbon of the different colour 'forms'
Best wishes,
Bill Rudman
