gastropod

Any member of a very large group of molluscs (soft-bodied invertebrate animals). Gastropods have a single shell (in a spiral or modified spiral form) and eyes on stalks, and they move on a flattened, muscular foot. They have well-developed heads and rough, scraping tongues called radulae. Some are marine, some freshwater, and others land creatures, but they all tend to live in damp places. (Class Gastropoda.)

Gastropods include land snails, slugs, abalones, conches, coneshells, and cowries.
