Perissityidae is an extinct taxonomic family of fossil sea snails, i.e., marine gastropod mollusks. [2]
The gastropods, commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda.
Heterobranchia, the heterobranchs, is a taxonomic clade of snails and slugs, which includes marine, aquatic and terrestrial gastropod mollusks.
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.
Volutoidea is a taxonomic superfamily of predatory sea snails, marine gastropod mollusks in the clade Neogastropoda.
Conoidea is a superfamily of predatory sea snails, marine gastropod mollusks within the suborder Hypsogastropoda. This superfamily is a very large group of marine mollusks, estimated at about 340 recent valid genera and subgenera, and considered by one authority to contain 4,000 named living species.
Helicoidea is a taxonomic superfamily of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the clade Stylommatophora.
Cystiscidae is a taxonomic family of minute sea snails, marine gastropod mollusks or micromollusks.
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.
Eucyclidae is a family of gastropods in the superfamily Seguenzioidea.
Nudipleura are a clade of sea snails and sea slugs, marine gastropod mollusks within the large clade Heterobranchia.
The Ptenoglossa is an informal taxonomic group of sea snails. This group was considered paraphyletic or polyphyletic by Ponder and Lindberg (1997) in their classification of gastropod molluscs.
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.
Velutinoidea 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.
Pupilloidea is a superfamily of small and very small air-breathing land snails, terrestrial gastropod mollusks in the informal group Orthurethra.
Triphoroidea is a superfamily of minute sea snails, marine gastropod molluscs or micromolluscs within the informal group Ptenoglossa.
Olivoidea is a taxonomic superfamily of minute to medium-large predatory sea snails, marine gastropod mollusks in the clade Neogastropoda.
