Hexacorallia Sea Anemones

Bolocera tuediae 283), and Pseudactinia varia 284). The amino acid composition of some of these toxins have been determined. 

Bernheimer and Avigad 285) examined seven kinds of sea anemones for the presence of cytolytic toxins. Tealia lofotensis and Epiactis prolifera yielded especially powerful preparations, whereas the extracts of the other species showed weaker cytolytic activity. Natural-abundance NMR studies have been performed on toxic polypeptides. These studies of APA and ATX II indicated that their overall conformation was very similar 286). 

The sea anemone Metridium senile furnished eight known epidioxy sterols (3-5, 9, 10, 12, 13, 15) in addition to a new compound (399) 323a). Milkova et al. 324, 325) have investigated the sterol composition of Black Sea invertebrates. They examined the sea anemone Actinia equina as well as two species of jellyfish.
