All Cephalopods Venomous

Date: 2/6/2009

Scientific studies from Universities of Melbourne and Brussels and Victoria Museum found that, while the blue-ringed octopus is dangerous to humans, other groups use their venom for predation. Bryan Fry, from the University of Melbourne said ‘By understanding the structure and mode of action of venom proteins we can benefit from drug design for a range of conditions such as pain management, allergies and cancer.’ The team analysed samples from octopus, cuttlefish and squid. It was found that a venomous ancestor produced one set of venom proteins, but over time additional proteins had added to the chemical arsenal.
