Diplodonta is a genus of marine bivalves belonging to the family Ungulinidae. [1] [2] [3] The genus has cosmopolitan distribution. [3]
There are 27 recognized extant species: [2]
Marginella is a very large genus of small tropical and temperate sea snails, marine gastropod molluscs in the subfamily Marginellinae of the family Marginellidae, the margin snails. It is a type of genus family.
Nucula is a genus of very small saltwater clams. They are part of the family Nuculidae.
Teinostoma is a genus of minute sea snails, marine gastropod mollusks or micromollusks in the family Teinostomatidae.
Lyonsiidae is a family of small saltwater clams, marine bivalve molluscs in the order Anomalodesmata.
Verticordiidae is a family of benthic marine bivalves in the superorder Anomalodesmata. These clams range from 2 - 200 millimeters in length and are mainly found in coastal waters surrounding Australia and the Americas, though a few species within this family such as Haliris mediopacifica are found in the middle of the ocean. Verticordiidae is known for being a family of septibranchs, or predatory bivalves, rather than filter feeders. Clams dig vertical burrows in substrate and use papillae around the edges of their inhalant siphons to detect microscopic prey. Some clams in this family, specifically in the genus Trigonulina, have distinct extended circular formations on their shells.
Macoma is a large genus of saltwater clams, marine bivalve molluscs in the family Tellinidae, the tellins.
Mangelia is a large genus of sea snails, marine gastropod mollusks in the family Mangeliidae.
Corbula is a genus of very small saltwater clams, marine bivalve molluscs in the family Corbulidae, the basket clams.
Melanella is a genus of very small ectoparasitic sea snails, marine gastropod molluscs or micromolluscs in the family Eulimidae.
Rissoa is a genus of minute sea snails, marine gastropod mollusks or micromollusks in the family Rissoidae.
Rissoina is a large genus of minute sea snails, marine gastropod molluscs or micromolluscs, in the family Rissoinidae.
Eulima is a genus of small, ectoparasitic sea snails, marine gastropod mollusks in the family Eulimidae.
Abra is a genus of saltwater clams, marine bivalve mollusks in the family Semelidae. Members of this genus are mostly under 1.5 centimeters long, and have thin shells which are usually white. These bivalves normally live under the surface of sandy and muddy sediments, in the neritic zone.
Pitar is a genus of saltwater clams, marine bivalve molluscs in the subfamily Callocardiinae of the family Veneridae, the Venus clams. The genus contains over 60 species.
Acteocina is a genus of very small sea snails, bubble snails, marine opisthobranch gastropod mollusks in the family Tornatinidae, the canoe bubbles or chalice bubble snails.
Retusa is a genus of very small head-shield sea snails or barrel-bubble snails, marine gastropod molluscs in the family Retusidae.
Pseudotorinia is a genus of sea snails, marine gastropod molluscs in the family Architectonicidae, the staircase shells or sundials.
Codakia is a genus of saltwater clams, marine bivalve molluscs in the family Lucinidae.
Periglypta is a genus of bivalves in the family Periplomatidae.
Phlyctiderma is a genus of marine bivalves belonging to the family Ungulinidae.
