Ostrea
''Ostrea'' is a genus of edible oysters, marine bivalve mollusks in the family Ostreidae, the oysters. Fossil records 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''. As a result, the genus ''Ostrea'' includes about 150 extinct species. History At least one species within this genus, '' Ostrea lurida'', has been recovered in archaeological excavations along the Central California coast of the Pacific Ocean, demonstrating it was a marine taxon exploited by the Native American Chumash people as a food source. Species Species in the genus ''Ostrea'' include: * † '' Ostrea albertensis'' Russell & Landes, 1937 * '' Ostrea algoensis'' G. B. Sowerby II, 1871 *'' Ostrea angasi'' G.B. Sowerby II, 1871 * '' Ostrea angelica'' R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ostrea Edulis
''Ostrea edulis'', commonly known as the European flat oyster, is a species of oyster native to Europe. In Great Britain and Ireland, localized names include Colchester native oyster, mud oyster, or edible oyster. In France, ''Ostrea edulis'' are known as ''huîtres plates'' (flat oysters) except for those that come from the estuary in Brittany, France, which are known as Belons. The fossil record of this species dates back to the Miocene (age range: 15.97 million years ago to present day). Fossils have been found in Belgium, Italy, the Netherlands, Egypt, Greece, Spain, the United Kingdom, Austria, France and Germany.

Ostrea Lurida
''Ostrea lurida'', common name the Olympia oyster, after Olympia, Washington in the Puget Sound area, is a species of small, edible oyster, a marine bivalve mollusk in the family Ostreidae. This species occurs on the northern Pacific coast of North America. Over the years the role of this edible species of oyster has been partly displaced by the cultivation of non-native edible oyster species. ''Ostrea lurida'' is now known to be separate from a similar-appearing species, '' Ostrea conchaphila'', which occurs further south, south of Baja California, in Mexico. Molecular evidence has recently confirmed the separate status of the two species. However, previously, for a period of time, ''Ostrea lurida'' was considered to be merely a junior synonym of '' Ostrea conchaphila''. ''O. lurida'' has been found in archaeological excavations along the Central California coast of the Pacific Ocean, demonstrating that it was a marine species exploited by the Native American Chumash people. ...

Ostrea Angasi
The southern mud oyster, Australian flat oyster, native flat oyster, native mud oyster, or angasi oyster (''Ostrea angasi''), is endemic to southern Australia, ranging from Western Australia to southeast New South Wales and around Tasmania. ''Ostrea angasi'' superficially resembles ''Ostrea edulis'' and both species may be referred to with the name "flat oyster". However, the two species do not occur naturally in the same geographic distribution. Habitat This species is found in sheltered, silty or sand-bottomed estuaries at depths between 1 and 30 metres. Diet Flat oysters, like all other oyster species, are filter feeders, feeding on, and taking in anything small enough to be filtered in their gills. This may include plankton, microalgae or inorganic material. Predators Oyster growers at Coffin Bay, South Australia have observed stingrays eating their experimental commercial stocks of ''Ostrea angasi''.
