Cadlina from Point Lobos, California

Hi Bill, Dave, et. al.,

I found these guys while branching at Point Lobos on Saturday. My first guess was that they are Cadlina modesta but after staring at them a bit I'm not so sure and I'm wondering if they might be Cadlina sparsa. Some of the tubercles seem to have the characteristic dark ring or spot that is seen in C. sparsa.

Locality: Point Lobos State Reserve, 15 meters, CA, USA, Pacific, 24 February 2007, Rocky Reef.. Length: 10-20mm. Photographer: Clinton Bauder.

I've several of these animals lately and all of them look a lot like the enclosed pictures. Yellow spots down each side and a very light yellow or white background color. Gills and rhinophores are typically the same color as the rest of the animal.

Hi Clinton,

Sometimes I get the feeling that Bill's Forum has become the poster board for all the tough, in-betweens, that are almost impossible to ID from photos. Yours is just one of those. That said, since the rhinophores of your critter are white (not yellow as in Cadlina modesta, and since I note a couple of thin brown rings around the yellow tipped doral tubrcles, I vote for Cadlina sparsa.

Thanks for the challenge,,
