Concerning message #19359:

Dear Bill,
Sorry that I don't have any conclusive photos to confirm Skip's opinion. Perhaps the following two photos without strobe can help.

The current didn't allow much time for the close-ups or angles that I would like to have taken. Maybe next time.

Locality: Cozumel, Mexico, Caribbean

Thanks again,
Sean

Dear Sean,
Thanks for the quick response. In the close-up alongside there certainly seems to be a gap separating the parapodia, rather than an overlap, which would tip the scales towards Elysia clarki. The other point Skip mentioned, which is not so easy to quantify, is that in E. clarki, the anterior limit of the parapodia is much further back than in E. crispata so specimens of E. clarki have a definite 'neck' [see message #16728]. So I would agree with Skip that this is most probably E. clarki. No need to apologise for not having the perfect shot. As you say it is the perfect excuse for another visit to Cozumel.

Best wishes,
Bill Rudman
