The carnivorous snails have tongues that are covered with thousands of tiny teeth to tear apart food. The gastropod fossils from Jacksboro, TX shown below are from the Pennsylvanian, Finis formation, and these gastropods lived about 300 million years ago.
Slugs and snails belong to the class Gastropoda of molluscs (soft-bodied animals). Most gastropods are aquatic, but one group (subclass Pulmonata) have expanded into terrestrial habitats. Terrestrial snails and slugs in New Zealand are extremely diverse, and come in a variety of colours, shapes and sizes.
