Photographed by: Gary McDonald
This photo shows distinct mantle glands, which I don't find in specimens from central California, but have been reported in specimens from Washington.
I can't give you a positive ID for this photo, it could be an oddly colored Cadlina luteomarginata
as you have suggested. I have never seen a specimen colored like this, the ones I have seen have all had relatively large, yellow tipped tubercles on the dorsum. There has been some discussion on the Sea Slug Forum about the possibility of more than one species of similarly colored animals on the Pacific coast of North America
This is actually Cadlina luteomarginata
, not Acanthodoris hudsoni
. Acanthodoris hudsoni
has longer rhinophores, and more pointed papillae on the dorsum.
