Some eat both plant and animal matter; others eat only one type of food. Respiration is carried on by gills in the aquatic species; terrestrial forms have a pulmonary sac, or lung, in the mantle cavity. A few terrestrial species have returned to the sea, and consequently must rise to the surface to breathe. Eyes are borne on stalks or tentacles. Many snails, including all land snails, are hermaphroditic, but the majority of the marine species have separate sexes. A snail secretes a slimy path over which it progresses slowly by rhythmic contractions of the muscular base, or foot. Marine and terrestrial snails are eaten in various parts of the world. Snails are considered a delicacy in Europe and were eaten by primitive man and raised for food by the Romans. Certain harmful freshwater species harbor flukes and other parasites that cause disease in humans.

snail

Any species of gastropod that glides along on a broad tapered foot and has a high coiled shell into which it can withdraw. Snails are found in the ocean, in fresh waters, and on land. Most marine snails have gills in the mantle cavity (see mollusk). Most land and freshwater snails have no gills; they use the mantle cavity itself as a lung. Snails may be either scavengers (of dead plant or animal matter) or predators. Some species are used as food, and the shells of some are used as ornaments. See also limpet, periwinkle, slug, whelk.
