CerithiidaeCerithiidae common name the cerithiids or ceriths, is a large family of medium-sized marine gastropods in the clade Sorbeoconcha.

Ceriths are found worldwide on sandy bottoms, reef flats or coral reef rock covered with sand and algae. They live in warm or temperate waters; but mostly in tropical areas. A few have been found along the European coastline and a few species along the American coast. Some have been found in estuarine areas of mangrove forests close to the sea. Only a few species of the subfamily Bittiinae are found in deep water.

Ceriths are herbivores and detritivores that graze the sea bed.

detritivores waste or debris of any kind

Their slender shell is elongated with a pointed spire. They vary in size from less than a 1/4 inch (Bittium alternatum) to 6 inches (Cerithium nodulosum). The smallest shells are found in the subfamily Bittiinae.

The many whorls have radial sculpture with axial ridges and nodules. The aperture shows at its base a vague curve or a distinct siphonal canal. The aperture is closed off by a thin oval brown operculum that is corneous and paucispiral. The palatal wall of the aperture is somewhat enlarged and often shows a varix.
