Is this Acanthodoris brunnea?

From: Steve Lonhart

Hi Bill,

This was pulled up from a very sandy area in front of Moss Landing, California, USA. It was not brown, but has other features of Acanthodoris brunnea. There is also a damaged area--not sure if that is part of the gut poking through. There were several of these in the area. I brought it to the lab to photograph (hence the odd background color).

Locality: Moss Landing, 70 feet, California, USA, Pacific Ocean, 22 June 2007, Subtidal, sandy slope. Length: 30 mm. Photographer: S.I. Lonhart.

Cheers,
Steve

Hi Steve,

Your critter is actually Acanthodoris rhodoceras. The reddish bown rhinophores, tipped in black, and the black tipped papillations on the dorsum give this species away.

Hope this helps,
Dave Behrens
