[1820–30; < New Latin]
Any of various mollusks having a head with eyes and feelers, usually a coiled shell, and a muscular foot on the underside of its body with which it moves. Gastropods include both land-dwelling forms, like land snails and slugs, and aquatic species, like conchs, cowries, and whelks.
Word History Snails, conchs, whelks, and many other similar animals with shells are all called gastropods by scientists. The word gastropod comes from Greek and means "stomach foot," a name that owes its existence to the unusual anatomy of snails. While they don't have feet like ours, exactly, snails have a broad flat "foot" used for support and for forward movement. This foot runs along the underside of the animal—essentially along its belly. The Greek elements gastro-, "stomach," and -pod, "foot," are found in many other scientific names, such as gastritis (an inflammation of the stomach) and sauropod ("lizard foot," a type of dinosaur).
