Scientific classification
Kingdom:	Animalia
Phylum:	Mollusca
Class:	Bivalvia
Order:	Ostreoida
Family:	Ostreidae Rafinesque, 1815

Ostreidae are the true oysters. The family includes most species eaten under the name oyster. Pearl oysters are not true oysters because they belong to a different order, the Pterioida.

Like scallops, true oysters have a central adductor muscle. This causes a scar in the middle of the shell. It is the point of attachment. The shell is often irregular because oysters attach to substrates.
