Ostreidae Ostreoidea is a taxonomic superfamily of bivalve marine mollusc , sometimes simply identified as oysters , [ 1 ] containing two families. The ostreoids are characterized in part by the presence of a well developed axial rod . [ 2 ]
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. The shell tends to be irregular ...

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]
Although molecular studies suggest that Ostrea first appeared around the Eocene and originated no earlier than the Cretaceous, paleontologists have historically applied the genus to almost all fossil oysters from the Permian onward, many of which are only superficially similar to extant Ostrea. [1]
Crassostrea rhizophorae, also known as the mangrove cupped oyster, is a species of bivalve in the family Ostreidae. [1] [2] C. rhizophorae is one of the predominant oyster species in the South Atlantic, specifically in Central and South America. [1] [3] It is often found in the vast mangrove ecosystem along the coast of Brazil. [1]
Rock oysters are true oysters of the genus Saccostrea, belonging to the subfamily Saccostreinae of the family Ostreidae. [ 1 ] The best-known species is the Sydney rock oyster ( Saccostrea glomerata ).
