Notes:
The order Ostreida includes the true oysters. One superfamily (Ostreoidea) and two extant families are recognised within it. The two families are Ostreidae, the true oysters, and Gryphaeidae, the foam oysters.
Venerida is an order of mostly saltwater but also some freshwater bivalve molluscs. This order includes many familiar groups such as many clams that are valued for food and a number of freshwater bivalves.
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 Pteriida are an order of large and medium-sized marine bivalve mollusks. It includes five families, among them the Pteriidae.
The Pteriomorphia comprise a subclass of saltwater clams, marine bivalve molluscs. It contains several major orders, including the Arcida, Ostreida, Pectinida, Limida, Mytilida, and Pteriida. It also contains some extinct and probably basal families, such as the Evyanidae, Colpomyidae, Bakevelliidae, Cassianellidae, and Lithiotidae.
Palaeoheterodonta is a subclass 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.
Heteroconchia is a taxonomic infraclass of saltwater clams, marine bivalve molluscs, belonging to the subclass Autobranchia
Mytilida is an order of marine bivalve molluscs, commonly known as true mussels. There is one extant superfamily, the Mytiloidea, with a single extant family, the Mytilidae.
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.
Carditidae is a family of marine bivalve clams of the order Carditida, which was long included in the Venerida. They are the type taxon of the superfamily Carditoidea.
Isognomonidae is a family of medium-sized to large saltwater clams. They are pearl oysters, marine bivalve molluscs in the superfamily Pterioidea
Condylocardiidae is a family of small marine bivalve clams of the order Carditida.
The Pectinoidea are a superfamily of marine bivalve molluscs, including the scallops and spiny oysters.
Protobranchia is a subclass of bivalve molluscs. It contains the extant orders Nuculanida, Nuculida, and Solemyida.
Pectinida is a taxonomic order of large and medium-sized saltwater clams, marine bivalve molluscs, commonly known as scallops and their allies. It is believed that they began evolutionarily in the late Middle Ordovician epoch; many species, of course, are still extant.
Poromyoidea is a superfamily of molluscs. It used to contain only the family Poromyidae, but now it also contains Cetoconchidae Ridewood, 1903, as CetoconchaDall, 1886 was removed from Poromyidae and given its own family, according to the World Register of Marine Species.
Lucinida is a taxonomic order of saltwater clams, marine bivalve molluscs.
Astartoidea is a superfamily of bivalves in the order Carditida. In the World Register of Marine Species (WoRMS), it is considered a junior synonym of Crassatelloidea, whereas in ITIS Crassatelloidea is a separate superfamily containing Crassatellidae.
Carditoidea is a superfamily of marine bivalve clams.
Crassatelloidea is a superfamily of bivalves in the order Carditida. In the World Register of Marine Species (WoRMS), Astartoidea is considered a junior synonym of Crassatelloidea, whereas in ITIS Astartoidea is a separate family containing Astartidae and Cardiniidae – Cardiniidae itself being classified instead in Carditoidea by WoRMS.
