Oyster beds have an estimated 50 times the surface area of an equally sized flat bottom. The beds also attract a high concentration of larger predators looking for food. [15] The eastern oyster, like all members of the family Ostreidae, can make small pearls to surround particles that enter the shell.
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 ...
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 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]
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.
