Other articles where Ostreoida is discussed: bivalve: Annotated classification: Order Ostreoida (oysters and scallops) Shell valves unequal, variable, typically lacking hinge teeth; shell structure of foliated calcite, upper valve with outer prismatic calcite; most scallops with inner crossed-lamellar layers; dimyarian but most monomyarian; ctenidia pseudolamellibranch; mantle fusions lacking.
The order Ostreida includes the true oysters. One superfamily (Ostreacea) and two families are recognised within it. The two families are Ostreidae, the true oysters, and Gryphaeidae, the foam oysters. 2010 taxonomy ( edit ).
The Ostreidae, the true oysters, include most species of molluscs commonly consumed as oysters. Pearl oysters are not true oysters, and belong to the order Pteriida. Like scallops, true oysters have a central adductor muscle, which means the shell has a characteristic central scar marking its point of attachment.

Oyster. The oyster is a sessile (immobile) mollusc that is commonly found clinging onto shipwrecks, debris and harbour walls around the world. Oysters are bivalve molluscs meaning that they are closely related to other animals such as scallops, clams and mussels. Oysters are found in salt water environments all around the world but are more commonly found in more temperate regions where the.
Classification Osteogenesis imperfecta was initially classified by type according to a scheme developed by David Sillence, Australian clinical geneticist, based mainly on family history, clinical presentation and radiologic findings.
A new phylogenetic classification separates these groups into three superorders within the subclass Autobranchia: Isofilibranchia (mytiloids), Prionodonta (arcoids), and Pteriomorphia. The most complex radiation has been in the Pteriomorphia. Three orders originated in the early Palaeozoic: Pterioida, Limoida, and Ostreoida.
