Gastropoda (snails) Gastropods are snail-like and slug-like invertebrate (lacking a backbone) animals, and are types of mollusks. Snails have hard mineral shells; slugs lack shells. Because fossils mostly represent the hard parts of organisms, snails are the most common types of gastropod fossils. Slugs are not preserved as fossils.
