Update on Elysia crispata feeding
August 6, 2004
From: Skip Pierce
Note added 30 May 2006: This may also refer to Elysia clarki, a new species which was previously considered a colour form of E. crispata
Glad to see the forum back in limited action. Quick note on Elysia crispata feeding. we're about to publish a paper on it, but you can raise the slug from juvenile to adult on Bryopsis for sure, and at least for a while, on Derbesia. The adults (but not the juveniles) also eat Penicillus capitatus and we have found chloroplast gene sequences from that species of alga in field collected slugs, along with Halimeda. Puzzlingly, in spite of the literature, we have found no evidence that they eat any species of Caulerpa - as juveniles or adults - in either feeding experiments or from molecular markers. We still don't know all the details of the life cycle-but I'm starting to think it's quite long for E. crispata - maybe 2 years - but not without food. They can keep the symbiotic plastids going for 3-4 months, but that's it and without the correct food, will die after that.

Pierce, S., 2004 (Aug 6) Update on Elysia crispata feeding. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/12731Thanks Skip,
Very interesting. I had puzzled over how aquariists had by accident been able to breed E. crispata from eggs to adults in their tanks withour any Halimeda.
Best wishes
Bill Rudman
