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.‘Here we cover a few groups that seem to be very close to the crown group Gastropoda (slugs + limpets).’
- ‘The oval, flat foot is characteristic of the classes Monoplacophora, Polyplacophora and Gastropoda.’
- ‘Slugs are soft-bodied animals belonging to a class called Gastropoda (not insects).’
- ‘In the traditional classification system, the class Gastropoda has been divided into three subclasses, Prosobranchia, Pulmonata, and Opisthobranchia.’
- ‘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.’
Modern Latin (plural), from Greek gastēr, gastr- ‘stomach’ + pous, pod- ‘foot’.
