True Oysters
Ostreidae
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 the muscle's point of attachment. The shell tends to be irregular as a result of attaching to a substrate.
