 According to Goldfrank's "Toxicologic Emergencies", about 27 human deaths can be confidently attributed to cone snail envenomation.Most of the cone snails that hunt worms rather than fish are probably not a risk to humans, with the possible exception of larger species.One of the fish-eating species, the geography cone, "Conus geographus", is also known colloquially as the "cigarette snail", a gallows humor exaggeration implying that, when stung by this creature, the victim will have only enough time to smoke a cigarette before dying.
