Orthogastropoda was a major taxonomic grouping of snails and slugs, an extremely large subclass within the huge class Gastropoda according to the older taxonomy of the Gastropoda.
Sorbeoconcha is a taxonomic clade of snails, i.e. gastropods, mainly marine species with gills and opercula, within the clade Caenogastropoda.
Stylommatophora is an order of air-breathing land snails and slugs, terrestrial pulmonate gastropod molluscs. This taxon includes the majority of land snails and slugs.
Neritoidea is a taxonomic superfamily of mostly sea snails, nerites and their allies, marine gastropod mollusks in the order Cycloneritida.
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.
Neritiliidae is a family of submarine cave snails, marine gastropod mollusks or micromollusks in the clade Cycloneritimorpha.
Pseudorthonychiidae is an extinct, monogeneric family of fossil snails, gastropod mollusks in the clade Cycloneritimorpha.
Neritopsidae is a family of small sea snails and freshwater snails in the clade Cycloneritimorpha.
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.
Neritimorpha is a taxonomic grouping, an unranked clade of snails, gastropod mollusks. This grouping includes land snails, sea snails, some deepwater limpets, and also freshwater snails. This clade used to be known as the superorder Neritopsina.
Cycloneritida is a order of land snails, freshwater snails, and sea snails.
The Cerithioidea is a superfamily of marine, brackish water and freshwater gastropod containing more than 200 genera. The Cerithoidea are included in the clade Sorbeoconcha. The original name of this superfamily was Cerithiacea, in keeping with common superfamily endings at the time.
Elasmognatha is a taxonomic grouping, a clade, of air-breathing land snails and slugs, terrestrial pulmonate gastropod molluscs.
Pleurotomarioidea is a superfamily of small to large marine gastropods included in the order Pleurotomariida of the subclass Vetigastropoda.
Seguenzioidea is a superfamily of minute to medium-sized sea snails, marine gastropod mollusks in the clade Vetigastropoda.
Scaliolidae, common name scaliolids, is a family of minute sea snails, marine gastropod molluscs or micromollusks in the superfamily Cerithioidea, the ceriths and their allies.
†Nerrhenidae is an extinct taxonomic family of fossil sea snails, marine gastropod mollusks. Nerrhenidae is the only family in the superfamily Nerrhenoidea.
Delphinulopsidae is an extinct taxonomic family of fossil sea snails, marine, gastropod mollusks.
This overview lists proposed changes in the taxonomy of gastropods at the family level and above since 2005, when the taxonomy of the Gastropoda by Bouchet & Rocroi (2005) was published. In other words, these are recent updates in the way various groups of snails and slugs are classified.
Obtortionidae is a family of sea snails, marine gastropod molluscs in the superfamily Cerithioidea, that is within the clade Cerithimorpha or in clade Sorbeoconcha.
