Dear Bill,
My friend Ross Overstreet [ross@diver.net] took these photos at Ship Rock, Catalina Island, California, USA in May 2003.
We have been unable to identify it, can you help?

Thanks Chris & Ross,
If you have any photos showing the head end more closely - from front or underneath - it might be useful. Gordon Robilliard (1972) described a species Dendronotus albopunctatus from Washington State, and it has more lately been reported from Oregon (Behrens, 1991). Your animal fits in all the characters I can see in your photos, but of course I can't see its radular teeth. Robilliard also describes a distinct white line around the edge of the foot which I can't see in your photos. Behrens {1991} reports another species with white spots on the body as Dendronotus sp. 1. It doesn't seem to have a white edge to the foot. Both species, like yours, have no branching on the rhinophore sheath.

It is certainly an interesting find. I will look forward to an comments from local experts
Best wishes,
Bill Rudman
