Hi Bill;

I'm sorting through a multi-year backlog of unlabelled invertebrate images and found these photos. Is this an adult Hypselodoris ruthae?

Locality: west coast of  St. Vincent Is.. Caribbean. Depth: 30 feet. Length: 1 inch. July 2003. sand/muck bottom. Photographer: Keri Wilk

Dear Les,
The photos we now have on the Forum are giving us a much better idea of the colour pattern of this species. Your photos confirm the blue line up the innner edge of each gills and show at least the posterior white patch on each rhinophore. Your animal has a more complex pattern than many of the earlier ones. Either the presence of yellow lines, and the light blue, is variable, or perhaps as you suggest, they are absent in juveniles.
Best wishes,
Bill Rudman
