Sportellidae is a family of marine bivalve molluscs of the superfamily Cyamioidea.
Sportellidae shells are of moderate size, equivalve and with an external ligament set on small nymphs. The hinge has one or two cardinal teeth and inconspicuous laterals.
The Arcida is an extant order of bivalve molluscs. This order dates back to the lower Ordovician period. They are distinguished from related groups, such as the mussels, by having a straight hinge to the shells, and the adductor muscles being of equal size. The duplivincular ligament, taxodont dentition, and a shell microstructure consisting of the outer crossed lamellar and inner complex crossed lamellar layers are defining characters of this order.
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.
Tellina is a widely distributed genus of marine bivalve molluscs, in the family Tellinidae.
Mactridae, common name the trough shells or duck clams, is a family of saltwater clams, marine bivalve mollusks in the order Venerida.
Anomalodesmata is an superorder of saltwater clams, marine bivalve molluscs. This grouping was formerly recognised as a taxonomic subclass. It is called a superorder in the current World Register of Marine Species, despite having no orders, to parallel it with sister taxon Imparidentia, which does have orders.
Periplomatidae is a family of large marine bivalves of the Anomalodesmata order.
Vesicomyidae is a family of saltwater clams, marine bivalve molluscs in the superfamily Glossoidea.
Crassatellidae is a family of small saltwater clams, marine bivalve molluscs of the order Carditida.
Pandoridae is a taxonomic family of small saltwater clams, marine bivalves in the order Anomalodesmata.
Spisula is a genus of medium-sized to large marine bivalve mollusks or clams in the subfazmily Mactrinae of the family Mactridae, commonly known as surf clams or trough shells.
Protobranchia is a subclass of bivalve molluscs. It contains the extant orders Nuculanida, Nuculida, and Solemyida.
Pholadidea is a taxonomic genus of marine bivalve molluscs in the subfamily Martesiinae of the family Pholadidae. Most members of Pholididea bore into shale, soft rock and coral for shelter, with the exception of Pholididea (Hatasia) wiffenae, which is a wood-borer.
Arcinella is a genus of bivalve mollusc in the family Chamidae.
Cyathodonta is a genus of bivalve mollusc in the family Thraciidae.
Solecurtus is a genus of saltwater clam, a marine bivalve molluscs in the family Solecurtidae.
Basterotia is a genus of small white bivalves in the family Basterotiidae.
Lucinisca is a genus of saltwater clams, marine bivalve molluscs in the subfamily Lucininae of the family Lucinidae.
Parilimyidae is a family of bivalves belonging to the superorder Anomalodesmata.
Periglypta is a genus of bivalves in the family Periplomatidae.
Saccella is a genus of bivalves belonging to the family Nuculanidae.
