Rostanga pulchra from La Jolla, California

Hi Doc,

Thought I'd share these shots of the Red Dorid, Rostanga pulchra, found off the coast of Southern California. It was a first for me. The rhinophore shape is rather funky and unique.

Locality: Pt. Loma, La Jolla, approx. 70fsw, California, USA, Eastern Pacific Ocean, 16 May 2007, Reef. Length: 1.5 inch. Photographer: Kevin Lee.

Dear Kevin,

It certainly seems a good week for nice photos of Rostangarhinophores. You can also see in the photo alongside the way that Rostanga gills are usually shorter and more compact than most dorids, the gill circlet forming an upright tube in most species, perhaps to mimic the siphons of the sponge colonies on which they feed.

Best wishes,
Bill Rudman
