Studies show that in comparison to Crassostrea gigas, this species is slower in growth, and smaller size. Morphologically, its left valve is deeply cupped its shell is ridged or highly wrinkled. In its native range, mature eggs are produced in early winter, while in the US Pacific, it comes in late summer through early winter (Refs. 86666, 86667). It is also known to have a one-way gametic incompatibility barrier, which prohibits the sperm of this species to fertilize other species, i.e., Crassostrea gigas (Refs. 86666, 86668). Since 1947, this species has been imported to the US for experimental and commercial purposes (Ref. 86669). Its conservation status remains questionnable due to the lack of information on its distribution as well as the taxonomic confusion with Crassostrea gigas (Ref. 86665). This species is found in intertidal areas, particularly on hard substrates (Ref. 86665). Also occurs in a muddy flat (Ref. 106134) as well as in estuary in tidal flats (Ref. 106135). In general, suspension feeding bivalves mainly depend on phytoplankton and detritus material for nutrition (Ref. 107088).
