Pulmonata or pulmonates is an informal group (previously an order, and before that, a subclass) of snails and slugs characterized by the ability to breathe air, by virtue of having a pallial lung instead of a gill, or gills. The group includes many land and freshwater families, and several marine families.

Pulmonate, (subclass Pulmonata), any of various land, freshwater, and marine snails belonging to the class Gastropoda (phylum Mollusca) that have lost their ancestral gills and breathe instead by means of a “lung”—a highly vascularized saclike modification of the mantle cavity.

Panpulmonata is a taxonomic clade of snails and slugs in the clade Heterobranchia within the clade Euthyneura. [1] Panpulmonata was established as a new taxon by Jörger et al. in October 2010. [1] The older name "Pulmonata" referred to a group of euthyneuran gastropods which were considered to be "air-breathers".

By far the largest group of land pulmonates is the order Stylommatophora, but there are also several primitive families of slugs (Veronicellidae, Rathousiidae, and Onchidiidae) and snails (Ellobiidae), which are wholly or partly terrestrial.

The meaning of PULMONATA is a very large order of Gastropoda (subclass Euthyneura) comprising most land snails and slugs and many freshwater snails that are distinguished by lacking gills which are usually replaced by a lung or respiratory sac formed by the modification of the mantle cavity and communicating with the exterior by a contractile ...

2008年3月25日 · This chapter focuses on the Pulmonata, gastropods belonging to the clade Heterobranchia. It explains that the pulmonates include the large majority of land snails and slugs, as well as many...

Pneumopulmonata is a superorder of heterobranch pulmonate gastropods belonging to the subterclass Tectipleura. It was defined based on results of phylogenomic studies [1][2] and named by Krug et al. (2022). The superorder unites all of Panpulmonata except for Sacoglossa. Synapomorphy of the group is the presence of a pneumostome.

Pul­monates are the land snails and slugs (a few species are ma­rine). A coiled shell is usu­ally pre­sent, but it is lost in some im­por­tant groups. Some detor­sion has oc­curred in many species.

2022年4月6日 · Transitions to terrestriality have been associated with major animal radiations including land snails and slugs in Stylommatophora (>20 000 described species), the most successful lineage of ‘pulmonates’ (a non-monophyletic assemblage of air-breathing gastropods).

Pulmonate, or lunged snails breathe via a lunglike pulmonary cavity, and they lack the hard trapdoor-like operculum found in gilled snails. Except for in the Ozarks, pulmonate snails predominate in most of the aquatic regions in our state.
