Re: Sacoglossans on Caulerpa

Dear Bill and Jeff,

Hi. In partial answer to Jeff's query about the sacoglossans that feed on Caulerpa in Australia, I found some details in Burn (1989).

• 1. Tamanovalva babai Burn feeds on Caulerpa scalpelliformis (and congeners).
• 2 & 3. Midorigai australis Burn eats only C. simpliciuscuala and Edenttellina typica Gatliff & Gabriel eats C. brownii.
• 4. Roburnella wilsoni (Tate) does feed on Caulerpa scalpelliformis (and congeners).
• 5. Oxynoe viridis (Pease) feeds on Caulpera spp. (Jeff, please note the Bill's photo of O. viridis on the Sea Slug Forum is shown on Caulerpa filiformis).

More specific details are in Burn (1989) as well as in the chapter by Burn in Mollusca: A Southern Synthesis. If your library does not have a copy of the latter, it might have a copy of this:

Burn, RD 1989 Order Sacoglossa. pp. 747-757 In: Marine invertebrates of Southern Australia. Part II. S.A. Shepherd & I.M. Thomas (Eds.). South Australian Government Printing Division, Adelaide.

All the best!
Cordially,
Cynthia

Thanks Cynthia,
One of the things I would like to do when I get a moment is post some of my photos of the southeastern Australian bivalve sacoglossans on their algal food.
best wishes,
Bill Rudman
