Crassostrea Columbiensis
''Crassostrea'' is a genus of true oysters (family Ostreidae) 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). Pacific species were moved to a new genus ''Magallana''. ''C. zhanjiangensis'' became '' Talonostrea zhanjiangensis''. The changes are not universally welcomed by oyster researchers, as ''C. gigas'' (now ''M. gigas'') is "one of the most researched species of marine invertebrate". Species Extant species are: Fossil species Fossil species include: * †''Crassostrea alabamiensis'' (Lea 1833) * †''Crassostrea ashleyi'' ( Hertlein 1943) (syn.

Eastern Oyster
The eastern oyster (''Crassostrea virginica'')—also called the Atlantic oyster, American oyster, or East Coast oyster—is a species of true oyster native to eastern North and South America. Other names in local or culinary use include the Wellfleet oyster, Virginia oyster, Malpeque oyster, Blue Point oyster, Chesapeake Bay oyster, and Apalachicola oyster. ''C. virginica'' ranges from northern New Brunswick south through parts of the West Indies to Venezuela. It is farmed in all of the Maritime provinces of Canada and all Eastern Seaboard and Gulf states of the United States, as well as Puget Sound, Washington, where it is known as the Totten Inlet Virginica. It was introduced to the Hawaiian Islands in the 19th century and is common in Pearl Harbor. The eastern oyster is an important commercial species. Its distribution has been affected by habitat change; less than 1% of the population present when the first European colonists arrived is thought to remain in the Che ...

Edible Bivalves
An edible item is any item that is safe for humans to eat. "Edible" is differentiated from " eatable" because it does not indicate how an item tastes, only whether it is fit to be eaten. Nonpoisonous items found in nature – such as some mushrooms, insects, seaweed, and so forth – are referred to as edible. Processed items that normally are not ingested but are specially manufactured to be so, like edible underwear or edible packaging, are also labeled as edible. Edible items in nature Humans eat thousands of plant species; there may be as many as 75,000 edible species of angiosperms, of which perhaps 7,000 are often eaten. Edible plants found in nature include flowers, seeds, berries, seaweed, and cacti. Being able to identify the versions of these plants that are safe to eat is an important survival skill. Some fungi, including certain types of mushrooms, are also edible. Many animals are also edible, including domesticated livestock as well as wild insects, amphibians ...

Bivalve Genera
Bivalvia () or bivalves, in previous centuries referred to as the Lamellibranchiata and Pelecypoda, is a class of aquatic molluscs (marine and freshwater) that have laterally compressed soft bodies enclosed by a calcified exoskeleton consisting of a hinged pair of half-shells known as valves. As a group, bivalves have no head and lack some typical molluscan organs such as the radula and the odontophore. Their gills have evolved into ctenidia, specialised organs for feeding and breathing. Common bivalves include clams, oysters, cockles, mussels, scallops, and numerous other families that live in saltwater, as well as a number of families that live in freshwater. Majority of the class are benthic filter feeders that bury themselves in sediment, where they are relatively safe from predation. Others lie on the sea floor or attach themselves to rocks or other hard surfaces. Some bivalves, such as scallops and file shells, can swim. Shipworms bore into wood, clay, or stone an ...

Magallana Gigas
The Pacific oyster, Japanese oyster, or Miyagi oyster (''Magallana gigas'') is an oyster native to the Pacific coast of Asia. It has become an introduced species in North America, Australia, Europe, and New Zealand. Etymology The genus ''Magallana'' is named for the Portuguese explorer Ferdinand Magellan and its specific epithet ''gígās'' is from the Greek for "giant". It was placed in the genus '' Crassostrea'' until 2017; from the Latin ''crass'' meaning "thick", ''ostrea'' meaning "oyster". In 2017, the WoRMS, following the DNA-based opinion of Salvi ''et al.'', moved all pacific members of ''Crassostrea'' to ''Magallana''. Parts of the scientific community resist this change and continue to argue that ''Crassostrea gigas'' should be the proper name. They argue that Salvi's DNA sampling is incomplete, and that criteria other than the genetic sequence should have been considered. Description The shell of ''M. gigas'' varies widely with the environment where it is attached. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Leo George Hertlein
Leo George Hertlein (1898 – 1972) was an American paleontologist and malacologist who studied the Recent and fossil mollusks of the eastern Pacific Ocean. Biography Hertlein was born on a farm in Pratt County, Kansas. After graduating high school in Wichita, Kansas, he moved to the West Coast and entered the University of Oregon as a geology major. After graduating with a B.A., Hertlein enrolled as a graduate student at Stanford University. He received his doctorate in 1929. His dissertation was on the Pliocene fossils of the San Diego, California area. In 1929, Hertlein was appointed assistant curator of the Department of Paleontology at the California Academy of Sciences. He rose to become the curator of Invertebrate Paleontology and was elected a Fellow. In the 1930s, he traveled to the Galapagos Islands and the nearshore areas of Central America and Mexico. He published over 150 papers on Recent and fossil mollusks, echinoderms, and brachiopod Brachiopods (), p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinction
Extinction is the termination of an organism by the death of its Endling, last member. A taxon may become Functional extinction, functionally extinct before the death of its last member if it loses the capacity to Reproduction, reproduce and recover. As a species' potential Range (biology), range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxon, Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the Fossil, fossil record) after a period of apparent absence. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include Dinosaur, non-avian dinosaurs, Machairodontinae, saber-toothed cats, and mammoths. Through evolution, species arise through the process of specia ...
