|A group of shells of various species of cone snails|
The snails within this family are sophisticated predatory animals. The snails have eyes, and are active hunters. They immobilize prey with a modified radular tooth. The tooth delivers venom with neurotoxins; it is launched out of the snail's mouth in a harpoon-like action.
There have been many suggested changes to the classification of cone shells, and the details are still under investigation. The very large genus Conus has 600 species, and there are six other subfamilies.
