The largest known extinct bivalve is a species of Platyceramus whose fossils measure up to 3,000 mm (118 in) in length. [64] In his 2010 treatise, Compendium of Bivalves, Markus Huber gives the total number of living bivalve species as about 9,200 combined in 106 families. [65]
Freshwater bivalve species vary greatly in size. Some pea clams (genus Pisidium) have an adult size of only 3 mm (0.12 in). In contrast, one of the largest species of freshwater bivalves is the swan mussel from the family Unionidae; it can grow to a length of 20 cm (7.9 in), and usually lives in lakes or slow-flowing rivers.
The colored lagoon cockle (Monodacna colorata), also known as the colored egg cockle or Azov-Black Sea cockle, [1] is a fresh- and brackish-water bivalve mollusc of the family Cardiidae characterized by a broadly oval shell, with oblique triangular ribs and a length of up to 40 mm. Its coloration varies from whitish or yellowish to pinkish or ...
The giant clam (Tridacna gigas) is generally considered to be the largest bivalve mollusc. It is indeed the heaviest species, growing to over 200 kg (440 lb) and measuring up to 120 cm (47 in) in length, [2] but Kuphus polythalamius holds the record for the largest bivalve by length. A specimen owned by Victor Dan in the United States has a ...
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.
While there are four extinct species in the genus, [2] the only extant species is Kuphus polythalamius (also incorrectly spelled as Kuphus polythalamia). [3] [4] It is the longest bivalve mollusc in the world, where the only known permanent natural habitat is Kalamansig, Sultan Kudarat in the Philippines. [5] Members of this genus secrete ...
Anomia simplex is a typical species of bivalve mollusk in the family of Anomiidae, similar to blue mussels, American oysters, and bay scallops. [1] The family of Anomiidae ranges from saltwater clams to bivalve mollusks, which contains about 7 genera, including Anomia simplex.
The zebra mussel (Dreissena polymorpha) is a small freshwater mussel, an aquatic bivalve mollusk in the family Dreissenidae.The species originates from the lakes of southern Russia and Ukraine, [3] but has been accidentally introduced to numerous other areas and has become an invasive species in many countries worldwide.
