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]
