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.

Crassostrea is a genus of true oysters (family Ostreidae) [2] containing some of the most important oysters used for food. The genus was recent split in WoRMS, following the DNA-based phylogenies of Salvi et al. (2014 and 2017). Pacific species were moved to a new genus Magallana. C. zhanjiangensis became Talonostrea zhanjiangensis. [3]
