Conus geographus is a type of sea snail, found among coral reefs in the Indo-Pacific Ocean, and in the Red Sea. It is one of the few snails that can be dangerous to humans. The geography cone, like other cones, attacks its prey by using an extensible tentacle, tipped with a poisonous sting. The stinger is shaped like a hollow harpoon, even possessing rear-facing spines. The geography cone's toxin causes muscle paralysis, accompanied by pain, nausea, vomiting and abdominal colic. More severe cases display accelerated pulse, double vision, vocal paralysis and uncoordinated movements.
