Triton Cymatium sp., copyright Jason Marks.

Belongs within: Tonnoidea.
Contains: Cymatium (Monoplex), Cymatium (Ranularia).

The Cymatiinae, tritons and trumpet shells, are a group of predatory marine snails with usually thick and strongly sculptured shells. The whorls often bear strong varices that rarely line up with those of adjacent whorls. Some members of this group are very large; the giant triton Charonia tritonis is the second-largest living gastropod. They lay egg capsules in cup-shaped clusters in crevices or on the underside of stones (Wilson & Gillett 1971). Members of the group attack a range of invertebrate prey, including ascidians, echinoderms and other molluscs.

Characters (from Wilson & Gillett 1971, as Cymatiidae): Shell usually thick, heavy, strongly sculptured with nodules and spiral ribs, strong varices, teeth on outer lip, folds or ridges on columellar side of aperture; periostracum hairy, scaly or bristly; operculum horny.
