Cuthona columbiana from Carmel, CA

Hi Bill and Dave,

This is Cuthona columbiana (Catriona columbiana?) The other animal in 2 of the photos is Flabellina trilineata. The brown sponges I found these guys on was where I found Cuthona fulgens [message #19980]. The sponges were very fuzzy looking and seemed to have a variety of bryozoans and hydroids growing on them.

Locality: Carmel, 18 meters, CA, USA, Pacific, 03 June 2007, Rocky Reef (East Pinnacles in Carmel). Length: 7-8mm. Photographer: Clinton Bauder.

Hi Clinton,

Apparently you were having a pretty good day. So many tiny aeolids. Yes to all your ID's, and Catriona columbiana for sure, with those opaque white stripes up each ceras.

Hard to say what they are feeding on, but my guess is the hydroids. I can see the polyps, but no way to ID it.

Thanks for sharing,
Dave
