The tooth can be extended at least the length of the cone's shell. The cone animal locates its prey using its sense of smell. Once the prey is detected, the long tooth is plunged into its victim. Once paralyzed, the prey is swallowed whole. Digestion proceeds over a period of hours and concludes with the expulsion of undigested parts like shell or bone.
Most cones eat other mollusks, but a few evolved species hunt fish.
At least 10 human deaths in the South Pacific region have been attributed to Cone stings. Click image to view specific shell information.
