Food of Aplysia parvula in Mayotte
December 16, 2003
From: Marina Poddubetskaia
Dear Bill,
Here are photos of the algae my Aplysia parvula from Mayotte, were feeding on. Most of them were found inside this red alga. Do you know what species is it? In the Mediterranean, A. parvula is often found in the very similar alga Sphaerococcus coronopifolius.

Poddubetskaia, M., 2003 (Dec 16) Food of Aplysia parvula in Mayotte. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/11649Thanks Marina,
There has been a lot of interesting research on feeding in this species and it seems that some species of red algae are preferred over others, and the preferred ones contain metabolites [chemical compounds made by the plant] which are stored by the sea hares for their own defense. [see earlier message]. In SE Australia Delisia pulchra and Laurencia obtusa are the preferred algae, but I am not an expert on Indian Ocean algae.
Best wishes
Bill Rudman
