Cone snails of the family Conidae are a diverse group of predatory marine gastropods, mostly tropical in distribution, which hunt and immobilize prey using a modified harpoon-like radular tooth that can deliver neurotoxic conopeptides. All cone snails are venomous, though the danger posed to humans varies widely by species.
