Concerning message #10199:
Hi Bill,
I was just looking through the messages on Chromodoris coi and came across your comment in message #10199 regarding the substrate the nudibranchs are on. I know this is a rather belated response, but that is indeed a sponge and it does look like the same sponge in the photo of C. coi from Pohnpei (message #3518 ). However, at least in the Pohnpei example, the nudibranch was not found on that sponge, and crawled across it apparently by chance during the photo session. It did not seem at all interested in stopping to try to eat. Of course, it was being regularly flashed with a powerful strobe, so that could have affected its behavior.

Johnson, S., 2007 (Feb 1) Re: Chromodoris coi from Solomon Ids. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/21316Dear Scott,
Comments are never too late. At present the only direct evidence we have of C. coi feeding are the two messages on the Forum [#15477, #4924] of it on Chelonaplysilla violacea. If we get any more finds of it on that greyish sponge I guess we will need to try and identify it. If anyone has photos of this species feeding on or apparently 'at home' on a sponge I would be interested in seeing it, either to confirm it apparent choice of the purple Chelonaplysilla or to suggest it may like other sponges as well.
Best wishes,
Bill Rudman
