<P> Among the compounds found in cone snail venom are proteins which, when isolated, have great potential as pain - killing drugs . Research shows that certain component proteins of the venom target specific human pain receptors and can be up to 10,000 times more potent than morphine without morphine's addictive properties and side - effects . </P> <P> Conantokin - G is a toxin derived from the venom of C. geographus . Only 15 - 20 of the venom's 100 - 200 toxic peptides are used for feeding . It is believed that the other compounds are defensive, and that the venom is mainly used for defense . </P> <P> Recent research has revealed that C. geographus uses a form of insulin as a means of stunning its prey . This insulin is distinct from its own (with shorter chains) and appears to be a stripped down version of those insulins found in fish . Once this venom passes through a fish's gills, the fish experiences hypoglycaemic shock, essentially stunning it and allowing for ingestion by the snail . This poison mixture has been referred to as nirvana cabal . Along with the tulip cone snail C. tulipa, no other species (with the exception of humans) is known to have used insulin as a weapon . </P>

Why are scientists so interested in the geographic cone snail conus geographus
