Acanthodoris pilosa from Puget Sound

I found this mating pair and I am confused as to the ID of these guys. Separately I would name as two different speacies but together, I am not sure.

Locality: Port Townsend , 45 ft, WA, USA, Puget Sound, 16 November 2007, Rock Jetty. Length: 1 cm. Photographer: Richard Zade.

Hi Rich,

Members of the family Onchidorididae can be variable in coloration, with several species seeming to form a color gradation. My guess is this pair is Acanthodoris pilosa as I do not see a yellow margin, and no red on the tips of the rhinophores or gills. The dark colored individual is new to me. Very interesting.

Thanks,
Dave Behrens
