Turrids are carnivorous, predatory gastropods. Most species have a poison gland used with the toxoglossan radula, used to prey on vertebrates and invertebrate animals (mostly polychaete worms) or in self-defense.Duda, T.F., Jr., Kohn, A.J. & Palumbi, S.R. (2001) Origins of diverse feeding ecologies within Conus, a genus of venomous marine gastropods. Biological Journal of the Linnean Society, 73, 391–409. Some turrids have lost the radula and the poison gland. The radula, when present, has two or three teeth in a row. It lacks lateral teeth and the marginal teeth are of the wishbone or duplex type. The teeth with a duplex form are not shaped from two distinct elements but grow from a flat plate, by thickening at the edges of the teeth and elevation of the rear edge from the membrane.
