Pulmonata
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. Pulmonata are known from the Carboniferous Period to the present. Pulmonates have a single atrium and kidney, and a concentrated, symmetrical, nervous system. The mantle cavity is located 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. Linnean taxonomy The taxonomy of this group according to the taxonomy of the Ga ...

Panpulmonata
Panpulmonata is a taxonomic clade of snails and slugs in the clade Heterobranchia within the clade Euthyneura. Panpulmonata was established as a new taxon by Jörger et al. in October 2010. The older name "Pulmonata" referred to a group of gastropods which were considered to be "air-breathers". This meaning certainly does not apply to the panpulmonate groups Acochlidia, Sacoglossa and Pyramidelloidea, and also was inaccurate when applied to some of the more traditional pulmonate taxa such as Siphonarioidea or Hygrophila, most members of which lack permanently air-filled lungs. However, the term Panpulmonata was chosen by Jörger et al. (2010) to provide some continuity in the terminology. Panpulmonata consists of following taxa: * Siphonarioidea * Sacoglossa * Glacidorboidea * Amphiboloidea * Pyramidelloidea * Hygrophila * Acochlidiacea (mentioned as Acochlidia) * Eupulmonata: Stylommatophora, Systellommatophora, Ellobioidea, Otinoidea, Trimusculoidea.

Basommatophora
Basommatophora was a term that was previously used as a taxonomic informal group, a group of snails within the informal group Pulmonata, the air-breathing slugs and snails. According to the taxonomy of the Gastropoda (Bouchet & Rocroi, 2005), whenever monophyly has not been tested, or where a traditional taxon of gastropods has now been discovered to be paraphyletic or polyphyletic, the term "group" or "informal group" was used. Basommatophora are known from the Carboniferous to the Recent periods.(in Czech) Pek I., Vašíček Z., Roček Z., Hajn. V. & Mikuláš R.: ''Základy zoopaleontologie''. - Olomouc, 1996. 264 pp., . Most of the families in this suborder are air-breathing freshwater snails. The three most abundant families in terms of number of species are, the Lymnaeidae (pond snails), the Planorbidae (ramshorn snails) and the Physidae (pouch or bubble snails). These are found in ponds, creeks, ditches, and shallow lakes nearly worldwide. The Siphonariidae on the ot ...

Operculum (gastropod)
The operculum (; ) is a corneous or calcareous anatomical structure like a trapdoor that exists in many (but not all) groups of sea snails and freshwater snails, and also in a few groups of land snails; the structure is found in some marine and freshwater gastropods, and in a minority of terrestrial gastropods, including the families Helicinidae, Cyclophoridae, Aciculidae, Maizaniidae, Pomatiidae, etc. The operculum is attached to the upper surface of the foot and in its most complete state, it serves as a sort of "trapdoor" to close the aperture of the shell when the soft parts of the animal are retracted. The shape of the operculum varies greatly from one family of gastropods to another. It is fairly often circular, or more or less oval in shape. In species where the operculum fits snugly, its outline corresponds exactly to the shape of the aperture of the shell and it serves to seal the entrance of the shell. Many families have opercula that are reduced in size, and which a ...

Hygrophila (Gastropoda)
Hygrophila is a taxonomic superorder of air-breathing freshwater snails, aquatic pulmonate gastropod mollusks within the clade Panpulmonata. MolluscaBase eds. (2020). MolluscaBase. Hygrophila. Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=382243 on 2020-12-14 The families in this clade are basically air-breathing freshwater snails including freshwater limpets. The three families with the greatest number of species are the Lymnaeidae (pond snails), the Planorbidae (ramshorn snails) and the Physidae (pouch or bubble snails). These are found in ponds, creeks, ditches, and shallow lakes nearly worldwide. The snails in this clade have their eyes located at the base of their tentacles, rather than at the tips, as in the true land snails Stylommatophora. They have shells that are thin, translucent, and relatively colorless, and they lack an operculum. Taxonomy 1997 taxonomy In the older taxonomy of the Gastropoda (Po ...

Siphonarioidea
Siphonarioidea is a taxonomic superfamily of air-breathing sea snails or false limpets, marine gastropod mollusks in the clade Panpulmonata. Distribution The Siphonarioidea are broadly distributed across the globe, however they are known to be the most abundant and species diverse in the warmer temperate to subtropical regions. More specifically, they are found within the southern hemisphere of the Indo-Pacific region. They generally inhabit marine benthic regions, specifically the subtidal zones. Description Siphonarioidea are almost entirely marine organisms, as they have been found to have evolved into despite the terrestrial ecosystems inhabited by their ancestors. They inhabit the subtidal zones of marine ecosystems, and resemble true limpets with their non coiled, conical shells. Siphonarioidea are frequently referred to as "false limpets" due to some distinct differences despite their resemblance to these Patellogastropoda. For example, Siphonariid adults' dorso-ventr ...

Amphibola Crenata
''Amphibola crenata'' (''tītiko'' in the Māori language or mud-flat snail in English) is a species of air-breathing snail with an operculum, a pulmonate gastropod mollusc which lives in a habitat that is intermediate between the land and the sea, not entirely terrestrial and not entirely marine.Rosenberg, G. (2011). Amphibola crenata (Gmelin, 1791). Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=590660 on 2012-04-06 This is not a true land snail, but it is also not a true sea snail. Unlike almost all other snails that have opercula, this species breathes air. It is common in New Zealand. Powell A. W. B. (1979). William Collins Publishers Ltd, Auckland, New Zealand, Description The thick shell of this species is about 20 mm in size.

Taxonomy Of The Gastropoda (Bouchet & Rocroi, 2005)
The taxonomy of the Gastropoda as it was revised in 2005 by Philippe Bouchet and Jean-Pierre Rocroi is a system for the scientific classification of gastropod mollusks. (Gastropods are a taxonomic class of animals which consists of snails and slugs of every kind, from the land, from freshwater, and from saltwater.) The paper setting out this taxonomy was published in the journal ''Malacologia''. The system encompasses both living and extinct groups, as well as some fossils whose classification as gastropods is uncertain. The Bouchet & Rocroi system was the first complete gastropod taxonomy that primarily employed the concept of clades, and was derived from research on molecular phylogenetics; in this context a clade is a "natural grouping" of organisms based upon a statistical cluster analysis. In contrast, most of the previous overall taxonomic schemes for gastropods relied on morphological features to classify these animals, and used taxon ranks such as order, superorder ...
