Corambe steinbergae from California

From: Clinton Bauder

Hi Bill,

Back from another fun day on the Big Sur Coast. A long period swell made macro photography difficult but I did manage some improved images of Corambe steinbergae. These show the rhinophores and what I think are probably Corambe eggs.

Also to preempt the inevitable - yes, I do see the critter to the right of the Corambe s and it does look like a slug of some kind. Sadly I don't have any better images and whatever it is is very small indeed. Certainly I didn't see it when I took the pictures.

Locality: Little Sur Pinnacle, 10 meters, California, USA, Pacific, 28 September 2007, Macrocystis Kelp Blade. Length: 4 mm. Photographer: Clinton Bauder.

Dear Clinton,
Thanks for these photos and I have followed your hint about not starting a debate about the little juvenile 'something' in your photo. On safer ground, the eggs certainly look like those of Corambe. I have also included a closeup showing the extended bryozoan zooids, each with their circlet of feeding tentacles making them look much like a cnidarian polyp. For those of you who don't know, these bryozoans are the food of Corambe.

Best wishes,
Bill Rudman
