The venom paralyzes small fish almost instantly. Once this venom passes through a fish's gills, the fish experiences hypoglycaemicshock, essentially stunning it and allowing for ingestion by the snail. total geographic distributions of snail species are thus most-ly the result of range expansions that take place, generation However, some species are adapted to temperate environments, such as the Cape coast of South Africa, the Mediterranean, or the cool waters of southern California . [13], The tooth is hollow and barbed, and is attached to the tip of the radula in the radular sac, inside the snail's throat. It is known to grow up to 15cm, which for a snail is quite large. Their venom is a complex mix of hundreds of different toxins that is delivered through a harpoon-like tooth propelled from an extendable proboscis. The snail then retracts the radula, drawing the subdued prey into the mouth. [18] According to Goldfrank's Toxicologic Emergencies, about 27 human deaths can be confidently attributed to cone snail envenomation, though the actual number is almost certainly much higher; some three dozen people are estimated to have died from geography cone envenomation alone. The level of extinction risk is similar in other well assessed marine taxa, including corals (27% of species at risk) [7] , [44] and scombrid and billfish (11% of 61 species at risk) [45] . R.L.
