Doto columbiana on ostrich-plume hydroid, Aglaophenia struthionides or A. latirostris

"Big Pipe", the Hyperion 5-mile outfall pipe, El Segundo, California

ID thanks to Jeff Goddard, who comments:
"Doto columbiana differs from Doto kya in (1) lack of white grains in rhinophores and their sheaths, (2) having more diffuse dark pigment on the body that extends to the edges of the foot, and (3) specializes on hydroids of the genus Aglaophenia."
