- Any of various carnivorous or herbivorous mollusks of the class Gastropoda, having a head with eyes and feelers and a muscular foot on the underside of its body with which it moves. Most gastropods are aquatic, but some have adapted to life on land. Gastropods include snails, which have a coiled shell, and slugs, which have a greatly reduced shell or none at all.
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. Snails have a broad flat muscular 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).
