Like the other conesnails, it fires a harpoon-like, venom-tipped modified tooth into its prey; the harpoon is attached to the body by a proboscis, and the prey is pulled inside for ingestion. Search in feature They are the only two species known to use insulin as a natural weapon. (2011). predicted that the amount of time that a snail spends in its larval phase (in number of days) is important in determining its overall ability to disperse to new areas. having markings, coloration, shapes, or other features that cause an animal to be camouflaged in its natural environment; being difficult to see or otherwise detect. Within piscivorous snails, two primary methods of hunting . in determining the geographic distribution of rocky shore species, probably through its effects on larval dispersal patterns. Symptoms of a more serious cone snail sting include intense, localized pain, swelling, numbness and tingling and vomiting. A calcareous, smooth shell covers the mollusks soft body. In comparison with other species, the shell has a noticeably wider and convex mid-body, with a flattened spire.

The geographic cone is inactive during the day, burying itself in the sand to camouflage itself for both protection and hunting. The total geographic distributions of snail species are thus mostly the result of range expansions that take place, generation after generation, during the larval phase of their life cycles (other factors, such as availability of appropriate habitats, of course, are also important). Recent cone species database. (Johnson and Stablum, 1971), The geographic cone snail is a piscivore, thus it influences the ecosystem dynamics of coral reef populations of small fish species. The larval diet is unknown, but assumed to be smaller plankton. . It lives in reefs of the tropical Indo-Pacific, and hunts small fish.
