Cyrtoneritimorpha, also Cyrtoneritida, [2] is a clade of fossil sea snails, marine gastropod mollusks within the clade Neritimorpha.
This order contains two extinct families: Orthonychiidae and Vltaviellidae.
Heterobranchia, the heterobranchs, is a taxonomic clade of snails and slugs, which includes marine, aquatic, and terrestrial gastropod molluscs.
Caenogastropoda is a taxonomic subclass of molluscs in the class Gastropoda. It is a large diverse group which are mostly sea snails and other marine gastropod mollusks, but also includes some freshwater snails and some land snails. The subclass is the most diverse and ecologically successful of the gastropods.
Sorbeoconcha is a taxonomic clade of snails, i.e. gastropods, mainly marine species with gills and opercula, within the clade Caenogastropoda.
Hypsogastropoda is a clade containing marine gastropods within the clade Caenogastropoda.
Sea snails are slow-moving marine gastropod molluscs, usually with visible external shells, such as whelk or abalone. They share the taxonomic class Gastropoda with slugs, which are distinguished from snails primarily by the absence of a visible shell.
Arminoidea is a superfamily of small sea slugs, marine gastropod molluscs in the clade Nudibranchia.
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.
Nudipleura are a clade of sea snails and sea slugs, marine gastropod mollusks within the large clade Heterobranchia.
Elasmognatha is a taxonomic grouping, a clade, of air-breathing land snails and slugs, terrestrial pulmonate gastropod molluscs.
Architaenioglossa is a taxonomic group of snails which have gills and often an operculum. They are primarily land and freshwater gastropod mollusks within the clade Caenogastropoda.
The Limacoidei is a taxonomic infraorder of air-breathing land snails, semislugs and slugs, terrestrial pulmonate gastropod molluscs in the suborder Helicina
The Dexiarchia are a suborder of sea slugs, shell-less marine gastropod molluscs in the order Nudibranchia. This classification is based on the study by Schrödl et al., published in 2001, who recognized within this clade two clades Pseudoeuctenidiacea and Cladobranchia.
The Cladobranchia are a taxonomic clade of nudibranchs, sea slugs, marine gastropod molluscs in the clade Dexiarchia.
Scissurelloidea is a taxonomic superfamily of minute sea snails, marine gastropod mollusks or micromollusks in the subclass Vetigastropoda.
Ampullarioidea is a taxonomic superfamily of freshwater snails, aquatic gastropod mollusks within the informal group Architaenioglossa, which belongs to the clade Caenogastropoda (unassigned).
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.
Vanikoroidea is a superfamily of sea snails, marine gastropod molluscs in the clade Littorinimorpha. The superfamily Eulimoidea is a synonym of Vanikoroidea.
The Cingulopsoidea is a superfamily of sea snails, marine gastropod molluscs in the clade Littorinimorpha.
The Plakobranchacea are a clade of sea slugs, marine gastropod molluscs in the clade Sacoglossa.
