		Crassostrea gigas and Crassostrea angulata are thought to be the same species and have been treated as such here (see e.g.
		Crassostrea gigas from a disused oyster farm at Tighavullin, Scotland, were observed in 1993, nine years after the farm was shut down, though no young were observed (Smith 1994).

	Oyster - Wikipedia, the free encyclopedia
		The "true oysters" are the members of the family Ostreidae, and this includes the edible oysters, which mainly belong to the genera Ostrea, Crassostrea, Ostreola or Saccostrea.
		Examples are the Edible Oyster, Ostrea edulis, Eastern Oyster Crassostrea virginica, Olympia Oyster Ostreola conchaphila, Pacific Oyster Crassostrea gigas, Sydney rock oyster Saccostrea glomerata, and the Wellfleet oyster,
		Oysters are filter-feeders that draw water in over their gills through the beating of cilia.

		In contrast, living Crassostrea are restricted to brackish, hypersaline, and intertidal environments where they secrete comparatively smaller and thinner shells.
		Crassostrea titan valves are thicker than C. virginica valves at all ages, suggesting that faster growth rates allowed C. titan to reach a size refuge earlier in life.
		The stratigraphic and biogeographic distributions of thick-shelled Crassostrea are consistent with the view that they evolved from euryhaline populations originally living in estuarine refuges.

		TITLE: Differences in lectin-binding by hemocytes of oysters (Crassostrea virginica) from three regions and further evidence for the correlation between the presence of lathyrose and the absence of Haplosporidium nelsoni.
		We tested the hypothesis that if hemolymph agglutinins or other hemolymph proteins are important in the defense against these parasites, oysters with high "baseline" (pre-exposure) levels, or oysters that produce these substances after challenge, should have lower parasite burdens and survive longer than animals without these characteristics.
		We conclude that the serum agglutinins tested play no role in defense against either H. nelsoni or P. marinus, and that differences in total protein were related to pathology rather than disease resistance.

		They are among the three editors of The Eastern Oyster, a comprehensive 734-page textbook synthesizing the biology of Crassostrea virginica.
		While preliminary research shows the Asian oyster to be resistant to diseases plaguing native oyster populations in Chesapeake Bay, little is known about the Suminoe oyster’s biology or reef building capabilities.

	PAG-IX: PROGRESS IN MARKER DEVELOPMENT AND MAPPING IN THE EASTERN OYSTER, CRASSOSTREA VIRGINICA (Site not responding. Last check: 2007-10-23)
		For centuries the eastern oyster Crassostrea virginica has been the primary oyster species harvested in North American waters.
		Several labs have developed microsatellite markers for the eastern oyster, which, together with some anonymous nuclear markers, have been used to construct a preliminary linkage map.
		Genotyping early embryos is expected to remove segregation distortion due to high genetic load, but not distortion arising from from null alleles and amplification of non-target loci.

	Summary of Citation
		CRASSOSTREA also found just below weathered and burrowed sand of Hawthorn Formation at Shell Bluff, GA. Section at Shell Bluff shows same sequence as in Coastal Plain of NC (in ascending order: Claibornian sand, middle to upper Oligocene siliceous limestone, silty CRASSOSTREA bed, middle Miocene Hawthorn).
		Although CRASSOSTREA is found in underlying Chickasawhayan sediments of River bend Formation, authors believe oysters of Pollocksville Formation and of Hawthorn Formation at Shell Bluff represent early Miocene appearance of CRASSOSTREA GIGANTISSIMA (Finch).
		The overlying early Miocene Pollocksville (CRASSOSTREA beds of Baum and others) is reduced in status to informal Pollocksville beds.

		Oysters were artificially infected with the Beltsville strain of C. parvum and subjected to e-beam and microwave treatments.

	Crassostrea ariakensis
		The proposed introduction of Crassostrea ariakensis into Chesapeake Bay as a means to restore oyster populations presents a number of potential risks, such as pathogens and pathological conditions that require careful examination and research before approval.
		It is commonly assumed that Crassostrea ariakensis is synonymous with C.
		A multiplex set of species-specific markers from COI was able to distinguish all five Crassostrea species in a single-tube PCR.
