Informal group of gastropods
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.
The taxon Pulmonata as traditionally defined was found to be polyphyletic in a molecular study per Jörger et al. , dating from 2010.[1]
Pulmonata are known from the Carboniferous period to the present.[2]
Pulmonates have a single atrium and kidney, and a concentrated symmetrical nervous system. The mantle cavity is on the right side of the body, and lacks gills, instead being converted into a vascularised lung. 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 .[3]
Linnean taxonomy [ edit ]
The taxonomy of this group according to the taxonomy of the Gastropoda (Ponder & Lindberg, 1997) was as follows:
Order Pulmonata Cuvier in Blainville, 1814 - pulmonates
Shells of pulmonate stylommatophoran snails in a museum collection
An artistic but scientifically incorrect version of various European land snails and slugs (one species here is not a pulmonate), their food plants and fungi, and a beetle that eats mollusks, bottom right.

Superfamily Zonitoidea Mörch , 1864
? Superfamily Athoracophoroidea P. Fischer, 1883 = Tracheopulmonata
? Superfamily Succineoidea Beck, 1837 = Heterurethra
2005 taxonomy [ edit ]
Examples of Pulmonata: Achatina fulica top right, Bielzia coerulans top left, Praticolella berlandieriana center right, Megalobulimus oblongus in the center, Euglandina rosea center left, Helix pomatia bottom right & Ashmunella levettei bottom left
The taxonomy of this group according to the taxonomy of the Gastropoda (Bouchet & Rocroi, 2005) [4] was as follows:
Informal Group Pulmonata [ edit ]
Contains the informal group Basommatophora and the clade Eupulmonata
Informal Group Basommatophora [ edit ]
Contains the clade Hygrophila
Clade Eupulmonata [ edit ]
Contains the clades Systellommatophora and Stylommatophora
Contains the subclades Elasmognatha , Orthurethra and the informal group Sigmurethra
other Sigmurethra [ edit ]
Two superfamilies belongs to clade Sigmurethra, but they are not in the limacoid clade.
2010 taxonomy [ edit ]
Jörger et al. (2010)[1] analyzed major groups within the Heterobranchia using genetic data and found that Pulmonata as traditionally defined was polyphyletic , for instance some pulmonates were more closely related to Sacoglossa and Acochlidia . They proposed the more inclusive taxon Panpulmonata to unite the clades Siphonarioidea , Sacoglossa , Glacidorboidea , Pyramidelloidea , Amphiboloidea , Hygrophila , Acochlidia and Eupulmonata .[1]
