Crassostrea is a genus of true oysters (family Ostreidae ) 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 .[2] The changes are not universally welcomed by oyster researchers, as C. gigas (now M. gigas ) is "one of the most researched species of marine invertebrate".[3]

Genetics [ edit ]
The genome of Crassostrea gigas (now Magallana gigas ) has been recently sequenced revealing an extensive set of genes that enable it to cope with environmental stresses.[8]
