An illustration of various
Pulmonata (and one predator
arthropod in the lower right), an informal group of
snails and
slugs characterized by the ability to breathe air, by virtue of having a
pallial lung instead of a
gill, or gills. Pulmonata was previously a formal
taxon but lost its status as one in 2010. The group includes many land and freshwater families, and several marine families. Most species have a shell, but no
operculum, although the group does also include several shell-less slugs. Pulmonates are
hermaphroditic, and some groups possess
love darts.
