Eubranchus from British Columbia

September 12, 2007
From: Clinton Bauder

Hi Bill,

Part three of three Eubranchus messages [see also #20645, #20646 ]. These animals look kind of halfway between the other two. Markings are more reddish than green but they lack the white specks and don't appear to be transparent.

Locality: Browning Pass, 15 meters, British Columbia, Canada, Pacific, 27 August 2007, Rock Wall. Length: 3-6 mm. Photographer: Clinton Bauder.

Hi Clinton,

Hate to admit it buddy, but I cannot ID this critter. Just can't see enough detail. Does anyone else have any idea?

Thanks, I guess,

Hi Dave, Clinton,
Bernard Picton has long held that species of Doto are very specific about the hydroids they eat. This animal and the two other spotted ones [#20645, #20646] each seem to be on a different species of hydroid. Perhaps it might be an idea to take a good photo of the hydroid colony when photographing species of Doto. It may lead us to an easier way to identify similar looking species.
Best wishes
Bill Rudman
