Truncatelloidea is a superfamily of snails, gastropod mollusks in the clade Caenogastropoda. [1] [2]
The families are marine, brackish, freshwater and terrestrial. [1]
Rissooidea, originally named Rissoacea by Gray, 1847, is a taxonomic superfamily of small and minute marine snails, belonging to the clade Littorinimorpha.
Littorinimorpha is a large order of snails, gastropods, consisting primarily of sea snails, but also including some freshwater snails and land snails.
Hydrobiidae, commonly known as mud snails, is a large cosmopolitan family of very small freshwater and brackish water snails with an operculum; they are in the order Littorinimorpha.
The Buccinidae are a very large and diverse taxonomic family of large sea snails, often known as whelks or true whelks.
Bithyniidae is a family of small freshwater snails with an operculum, aquatic gastropod molluscs in the clade Littorinimorpha.
Potamopyrgus is a genus of minute freshwater snails with an operculum, aquatic gastropod molluscs or micromolluscs in the family Tateidae.
Rissoidae is a large family of very small and minute sea snails with an operculum, marine gastropod mollusks in the superfamily Rissooidea and the order Littorinimorpha.
Cerithiidae, common name the cerithiids or ceriths, is a large family of medium-sized marine gastropods in the clade Sorbeoconcha.
Tornidae is a family of very small and minute sea snails with an operculum, marine gastropod mollusks in the clade Littorinimorpha. This family used to be known as the Vitrinellidae. Iredale has shown that the family Adeorbidae Monterosato, 1884 should be called Tornidae
The Neotaenioglossa is a taxonomic name for a large group of mostly sea snails. The name was originally created by Haller in 1882. Ponder and Warén (1988), and Marquet (1997), assigned this name to the superorder Caenogastropoda. ITIS considers the order Neotaenioglossa to be a synonym of Cerithioidea Férussac, 1819 .
Cochliopidae is a family of small freshwater snails with gills and an operculum, aquatic gastropod mollusks. Paludestrina d'Orbigny, 1840 is an archaic synonym, and has been placed on the Official Index of Rejected and Invalid Names by ICZN Opinion 2202.
Pomatiopsidae is a family of small, mainly freshwater snails, that have gills and an operculum, aquatic gastropod mollusks in the superfamily Truncatelloidea.
Lithoglyphidae is a family of small freshwater snails with gills and an operculum, aquatic gastropod mollusks.
The taxonomy of the Gastropoda, as revised by Winston Ponder and David R. Lindberg in 1997, is an older taxonomy of the class Gastropoda, the class of molluscs consisting of all snails and slugs. The full name of the work in which this taxonomy was published is Towards a phylogeny of gastropod molluscs: an analysis using morphological characters.
Apogastropoda was previously used as a major taxonomic grouping of sea snails, marine gastropod molluscs. This infraclass mostly consisted of marine limpets and operculate snails. At least 20,000 species were considered to exist within the two clades that were included, Heterobranchia and Caenogastropoda.
Moitessieriidae is a family of small freshwater snails, aquatic gastropod molluscs in the superfamily Truncatelloidea.
Melanella is a genus of very small ectoparasitic sea snails, marine gastropod mollusks or micromollusks in the family Eulimidae.
Eulima is a genus of small, ectoparasitic sea snails, marine gastropod mollusks in the family Eulimidae.
Turbonilla is a large genus of ectoparasitic sea snails, marine gastropod mollusks in the family Pyramidellidae, the pyrams and their allies.
Tateidae is a family of very small and minute aquatic snails with an operculum, gastropod mollusks in the superfamily Truncatelloidea.
