This snail is a serial killer! Native to the reefs of the Indo-Pacific, the geography cone, a gastropod mollusc, possesses one of the most toxic venoms in the marine world. This conotoxin is synthesized in a long convoluted venom duct connected to a muscular bulb that ejects the venom through a hollow harpoon-like barb held by the proboscis. A prey is immobilised within one or two seconds, and ingugitated by the cone shortly after. In fact, the geography cone can kill a man in less than two hours. Ironically, the toxin (called ACV1) derived from the mollusc's venom is 1,000 times more powerful and effective than morphine as an analgesic, and is also better able to heal damaged nerves...!
