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]

Species[edit]

Extant species[edit]

Extant species include:[4]

Fossil species[edit]

Crassostrea gigantissima (Finch, 1824) from the EoceneofTexas.
Crassostrea gigantissima (Finch, 1824) right valve interior (Eocene of Texas).

Fossil species include:[5]

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]
