Re: Possible Eubranchus from False Bay

Hi Bill!
On a dive recently I also saw what I think may be a species of Eubranchus which is not in Gosliner, but looks similar to other Eubranchidae shown on this forum.

There were two varieties, one with red digestive tract extensions into the cerata, one with white. I found them close together, and with a number of egg ribbons, as can be seen in the group image. I have a close-up of the egg cases too, which I can send if needed.

Locality: Cape Town, 15 meters, South Africa, Atlantic Ocean, 9-April-2007, Hydroid colony on rock reef wall. Length: 15 mm. Photographer: Guido Zsilavecz.

Could this be a new species or is it familiar to you?
Thanks,
Guido

Dear Guido,
This is an aeolid but I don't think it is a eubranchid. From the way the cerata are arranged in many transverse rows, and the apparent lack of tentacle-like extensions to the anterior corners off the foot, my considered 'guess' is that it is a species of Cuthona.  

I can't find - or recall - it, so perhaps it is an unnamed species. Perhaps Terry Gosliner can give us a comment.

Best wishes,
Bill Rudman
