About this species

Conus geographus, popularly called the geography cone, geographer cone, or geographic cone, is a species of predatory cone snail. It lives in reefs of the tropical Indo-Pacific and hunts small fish. While all cone snails hunt and kill prey using venom, the venom of Conus geographus is potent enough to kill humans.
