Subterclass Euheterodonta
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.
Littorinimorpha is a large order of snails, gastropods, consisting primarily of sea snails, but also including some freshwater snails and land snails.
The Veneridae or venerids, common name: Venus clams, are a very large family of minute to large, saltwater clams, marine bivalve molluscs. Over 500 living species of venerid bivalves are known, most of which are edible, and many of which are exploited as food sources.
Palaeoheterodonta is a subterclass of bivalve molluscs. It contains the extant orders Unionida and Trigoniida. They are distinguished by having the two halves of the shell be of equal size and shape, but by having the hinge teeth be in a single row, rather than separated into two groups, as they are in the clams and cockles.
Buccinoidea is a taxonomic superfamily of very small to large predatory sea snails, marine gastropod mollusks.
Architectonicidae, common name the staircase shells or sundials, are a family of sea snails, marine gastropod mollusks in the informal group "Lower Heterobranchia" of the clade Heterobranchia.
Macoma is a large genus of saltwater clams, marine bivalve molluscs in the family Tellinidae, the tellins.
Polinices is a genus of predatory sea snails, marine gastropod molluscs in the subfamily Polinicinae of the family Naticidae, commonly known as moon snails.
Natica is a genus of small to medium-sized predatory sea snails, marine gastropods in the subfamily Naticinae of the family Naticidae, the moon snails. The genus was erected by Giovanni Antonio Scopoli in 1777.
Fasciolariidae is a family of small to large sea snails, marine gastropod mollusks in the superfamily Buccinoidea. Species in Fasciolariidae are commonly known as tulip snails and spindle snails.
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.
Turricula is a genus of sea snails, marine gastropod mollusks in the family Clavatulidae.
Panpulmonata is a taxonomic clade of snails and slugs in the clade Heterobranchia within the clade Euthyneura.
Cardioidea is a taxonomic superfamily of saltwater clams, marine bivalve molluscs consisting of the extant Cardiidae (cockles) and the extinct Pterocardiidae.
Serratina is a genus of marine bivalve molluscs, in the subfamily Tellininae of the family Tellinidae.
The taxonomy of the Gastropoda as it was revised in December 2017 by Philippe Bouchet and eight other authors, is a publication which lays out a newly revised system for the scientific classification of gastropod mollusks. The same work also included the taxonomy of monoplacophorans.
The following is a taxonomy of extant (living) Brachiopoda by Emig, Bitner & Álvarez (2019). There are over 400 living species and over 120 living genera of brachiopods classified within 3 classes and 5 orders, listed below. Extinct groups are not listed.
Tellinella is a genus of marine bivalve molluscs, in the subfamily Tellininae of the family Tellinidae.
