Three species of large predatory cone shells whose venomous harpoon is capable of killing a grown man,but which may also offer an amazing cure. From right to left: the geography cone Conus geographicus,the Striated cone Conus striatus,and the textile conus textile. the venom is shot out on a small spicule harpoon and is used to subdue prey. In defense against humans a different cocktail of venoms is employed - an unusual feature of the Cone shells complex toxin production. It can cause rapid paralysis and death in humans as it is a potent neurotoxin. Pharmacologically small doses of these complex venoms - called Conotoxins - are found to have remarkable posibilities for reducing pain - an effect estimated to be up to 100 times greater than that of morphine. They are currently undergoing investigation with a view to a clinical trial and marketing in the future | |
