This was a revised system for classifying bivalve mollusks such as clams, oysters, scallops, mussels and so on. In compiling this new taxonomy, the authors used a variety of phylogenetic information including molecular analysis , anatomical analysis, shell morphology and shell microstructure, as well as bio-geographic, paleobiogeographical and ...
Juliidae, common name the bivalved gastropods, is a family of small sea snails, marine gastropod mollusks or micromollusks in the superfamily Oxynooidea, an opisthobranch group. [ 2 ] These are sacoglossan (sap-sucking) sea snails, and many of them are green in color.
The taxonomic term Bivalvia was first used by Linnaeus in the 10th edition of his Systema Naturae in 1758 to refer to animals having shells composed of two valves. [3] More recently, the class was known as Pelecypoda, meaning "axe-foot" (based on the shape of the foot of the animal when extended).
The Unionidae are a family of freshwater mussels, the largest in the order Unionida, the bivalve molluscs sometimes known as river mussels, or simply as unionids. [1] [2]The range of distribution for this family is world-wide.
Lucinella divaricata, the divaricate lucine, is a small marine bivalve mollusc of the family Lucinidae found in the north eastern Atlantic and the Mediterranean. Its fossils are known from Cenozoic deposits all over Europe. [1] Chemoautotrophic bacteria in their gills enable them to survive well in substrates rich in hydrogen sulfide. [2]
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 blue mussel (Mytilus edulis), also known as the common mussel, [1] is a medium-sized edible marine bivalve mollusc in the family Mytilidae, the only extant family in the order Mytilida, known as "true mussels". Blue mussels are subject to commercial use and intensive aquaculture. A species with a large range, empty shells are commonly found ...
Lucinidae, common name hatchet shells, is a family of saltwater clams, marine bivalve molluscs. These bivalves are remarkable for their endosymbiosis with sulphide -oxidizing bacteria . [ 1 ]
