Selected chemo-ecological studies of marine opisthobranchs from Indian coasts.

The report summarizes the chemical and ecological studies of benthic marine invertebrates from the southern coast of the Indian peninsula. In particular, the paper is centred on the chemical investigations of opisthobranch molluscs (Volvatella sp., Jorunna funebris, Elysia sp., Glossodoris atromarginata, Chromodoris mandapamensis, Hypselodoris kanga and Haminoea cymbalum) and the associated preys, mainly sponges. It also describes the biological activity of the isolated compounds and the ecological role with special attention to their defensive and chemo-taxonomical significance.
