Elasmognatha is a taxonomic grouping, a clade, of air-breathing land snails and slugs, terrestrial pulmonate gastropod molluscs.
A number of species in this taxonomic group are endangered.
In the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005, [1] Elasmognatha is treated as a clade within the larger clade Stylommatophora.
The following two superfamilies and families have been recognized in the taxonomy of Bouchet & Rocroi (2005):
Sorbeoconcha is a taxonomic clade of snails, i.e. gastropods, mainly marine species with gills and opercula, within the clade Caenogastropoda.
Neritopsoidea is a taxonomic grouping, a superfamily of sea snails, marine gastropod mollusks in the clade Cycloneritimorpha, within the clade Neritimorpha,, or in the order Neritoina within superorder Cycloneritimorpha within the subclass Neritimorpha,.
Buccinoidea is a taxonomic superfamily of very small to large predatory sea snails, marine gastropod mollusks.
Arminoidea is a superfamily of small sea slugs, marine gastropod molluscs in the clade Nudibranchia.
Polyceroidea is a taxonomic superfamily of sea slugs, specifically dorid nudibranchs, marine gastropod mollusks in the clade Doridacea.
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. 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.
Pyramidelloidea is a superfamily of mostly very small sea snails, marine gastropod mollusks and micromollusks within the clade Panpulmonata.
Aillyidae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the informal group Sigmurethra.
Vetigastropoda is a major taxonomic group of sea snails, marine gastropod mollusks that form a very ancient lineage. Taxonomically the Vetigastropoda are sometimes treated as an order, although they are treated as an unranked clade in Bouchet and Rocroi, 2005.
Orthurethra is a clade of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the clade Stylommatophora.
Cycloneritida is an order of land snails, freshwater snails, and sea snails.
Doridacea is a taxonomic grouping of dorid nudibranchs, shell-less marine gastropod mollusks. included in the clade Euctenidiacea of the clade Nudibranchia.
Turbinoidea was a superfamily of small to large sea snails, marine gastropod mollusks in the clade Vetigastropoda. But it has become an available name, because it is no longer used in the current taxonomy of gastropods sensu Williams et al. (2008).
The Limacoidei is a taxonomic infraorder of air-breathing land snails, semislugs and slugs, terrestrial pulmonate gastropod molluscs in the suborder Helicina
Scissurelloidea is a taxonomic superfamily of minute sea snails, marine gastropod mollusks or micromollusks in the subclass Vetigastropoda.
Viviparoidea is a taxonomic superfamily of freshwater snails, aquatic gastropod mollusks within the informal group Architaenioglossa, which belongs to the clade Caenogastropoda.
Xenophoroidea is a superfamily of sea snails, marine gastropod molluscs in the clade Littorinimorpha.
Runcinoidea is a taxonomic superfamily or a clade Runcinaecea of sea slugs, marine gastropod mollusks in the order Runcinida
Cymbulioidea is a taxonomic superfamily of pelagic "sea butterflies", one group of swimming sea snails. They are holoplanktonic opisthobranch gastropod molluscs in the clade Thecosomata.
Obtortionidae is a family of sea snails, marine gastropod molluscs in the superfamily Cerithioidea, that is within the clade Cerithimorpha or in clade Sorbeoconcha.
