Dear Bill & Skip,
I am sitting in the middle of my moving mess (this time I only moved about 100m to a larger apartment - where supposedly I will not have to keep books in boxes on the floor, though that is exactly what I do have all around me), and then this interesting conversation pops up. I will be very interested in hearing Skip's results about the feeding of Elysia crispata. I have actually observed the juveniles (hatched from egg masses in the lab) feed on Caulerpa verticillata, so I know that they can feed on this alga and grow. I have never seen an adult E. crispata feed on anything, and in most cases they didn't grow in our tanks - they were just there for months, spawning and looking healthy - and maybe feeding after the lights were off at night.

I would like to know if the presence of fucoxanthin implies that it feeds on brown algae, because this has been implied for the very similar E. (Tridachiella) diomedea [= Tridachiella diomedea], but never confirmed.

Greetings,
Kathe

Thanks Kathe,
I'm glad to see you haven't let a domestic crisis interfere with a good slug story
