title: Biologically active polypeptides in the venom of the jellyfish Rhopilema nomadica.
abstract: A tropical jellyfish, Rhopilema nomadica (Scyphozoa, Rhizostomeae) has recently invaded the eastern Mediterranean. Its painful stings have been the bane of bathers and fishermen from Egypt to Turkey. This paper reports on the presence of haemolytic activity and alpha-chymotrypsin-like serine protease activity in the venom of the R. nomadica nematocysts. In addition, the presence of phospholipase A2 activity, which has been described previously, is confirmed. Some properties of these activities are defined.
