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.
Oestroidea have a wide range of feeding habits and breeding environments: saprophagous (many Calliphoridae and Sarcophagidae), feeding on blood of birds or mammals (some Calliphoridae), parasites of gastropods or earthworms (some Calliphoridae), parasitoids of arthropods (Rhinophoridae, Tachinidae and some Sarcophagidae), living in association with termites or ants (some Calliphoridae and ...

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]

The World Register of Marine Species lists these species: [1] Saccostrea circumsuta (Gould, 1850); Saccostrea cucullata (Born, 1778) – hooded oyster; Saccostrea echinata (Quoy & Gaimard, 1835) – tropical black-lip rock oyster
Agerostrea is an extinct genus of fossil oysters, marine bivalve molluscs in the family Ostreidae, the true oysters. It is present in the Maastrichtian , the upper stage of the Late Cretaceous epoch, from 72.1 to 66 million years ago.
