Has anyone seen Corambe pacifica swimming? I was snorkel-swimming off La Jolla Shores, San Diego, California, when I noticed a lot of activity a foot below the water's surface. I realized that it was a Corambe. I grabbed a piece of bryozoan-encrusted Macrocystis nearby and placed it under the animal. It alighted and "dissappeared" against its backdrop. Since many species of nudibranchs don't swim, I am interested to find out if anyone else has seen this.
Locality: La Jolla, 2 feet below surface, CA, USA, Pacific Ocean, 12 July 2006, water column. Length: 6-7 mm long. Photographer: no picture.

Interesting observation. Since very few people ever find this highly cryptic animal in the first place, I am sure you are likely the first to see one "swimming." This is the first report of this behavior I have ever heard of. I am wondering if you might have dislodged the critter while snorkeling. Cryptic dorids like this species don't really have a need to swim with their food so abundant, and their disguise so perfect.
Thanks for sharing this observation,
