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] 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".[4]

Extant species are:[2]
- Crassostrea aequatorialis (A. d'Orbigny, 1846)

- Crassostrea mangle Amaral & Simone, 2014
- Crassostrea rhizophorae (Guilding, 1828)
- Crassostrea tulipa (Lamarck, 1819) – mangrove oyster

Genetics
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]
