Atagema alba from southern California

From: Jim Lyle

Dear Bill,

Behrens and Hermosillo show this dorid as Atagema alba. As the slug forum does not have this branch in the species list, I thought I would pass along the image.

Locality: Buchanan's Reef, Palos Verdes, 20 metres, California, USA, Pacific Ocean, 22 July 2007, Rocky reef. Length: 20 mm. Photographer: Jim Lyle.

Hi Jim,

Nice find. This species is certainly not very common. It is readily identified by the strong irregular dorsal ridge, and the three extra-branchial lobes, shown in the close-up.

Thanks for adding this species to the Forum,
Dave Behrens
