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).
A few species of molluscs are not commonly eaten now, but were eaten in historical or prehistoric times. The list is divided into marine and non-marine (terrestrial and freshwater) species, and within those divisions, the lists are primarily arranged taxonomically , so that related species are grouped together.
In some species, the valves are highly calcified, and many are somewhat irregular in shape. Many, but not all oysters, are in the superfamily Ostreoidea. Some species of oyster are commonly consumed and are regarded as a delicacy in some localities. Some types of pearl oysters are harvested for the pearl produced within the mantle.
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.
Maryland DNR has selected next three sites for oyster restoration in Maryland waters of the Chesapeake Bay, including one on the lower Eastern Shore.
Around 76,000 extant species of molluscs are recognized, making it the second-largest animal phylum after Arthropoda. The number of additional fossil species is estimated between 60,000 and 100,000, and the proportion of undescribed species is very high. Many taxa remain poorly studied.
