A large class of molluscs which includes snails, slugs, whelks, and all terrestrial kinds. They have a large muscular foot for movement and (in many kinds) a single asymmetrical spiral shell.
- ‘The oval, flat foot is characteristic of the classes Monoplacophora, Polyplacophora and Gastropoda.’
- ‘Here we cover a few groups that seem to be very close to the crown group Gastropoda (slugs + limpets).’
- ‘Slugs are soft-bodied animals belonging to a class called Gastropoda (not insects).’
- ‘Theoretical issues include which taxa even belong to the Gastropoda and macroevolutionary patterns such as the pervasiveness of trends and shifting rates of morphologic change and cladogenesis.’
- ‘In the traditional classification system, the class Gastropoda has been divided into three subclasses, Prosobranchia, Pulmonata, and Opisthobranchia.’
Modern Latin (plural), from Greek gastēr, gastr- stomach + pous, pod- foot.
