Cambaroides
''Cambaroides'' is a genus of freshwater crayfish from eastern Asia (eastern Russia, northeastern China, Korean Peninsula and Japan). Together with ''Astacus'', they are the only crayfish native to Asia. ''Cambaroides'' contains about six species: * ''Cambaroides dauricus'' (Pallas, 1772) * ''Cambaroides japonicus'' (De Haan, 1841) * ''Cambaroides koshewnikowi'' (Birstein & Vinogradov, 1934) * ''Cambaroides sachalinensis'' ( De Haan, 1841) * ''Cambaroides schrenckii'' (Kessler, 1874) * ''Cambaroides similis'' (Koelbel, 1892) * ''Cambaroides wladiwostokiensis ''Cambaroides wladiwostokensis'' is a species of crayfish endemic to Primorsky Krai (Vladivostok Vladivostok ( rus, Владивосто́к, a=Владивосток.ogg, p=vɫədʲɪvɐˈstok) is the largest city and the administrative cent ...''

Cambaroides Schrenckii
''Cambaroides schrenckii'' is a species of crayfish endemic to north-eastern China and Russia. It is a freshwater species that also occurs in some brackish water areas. It occurs in habitats with still water, typically no more than 1 metre deep. It was named after Leopold von Schrenck Peter Leopold von Schrenck (russian: Леопольд Иванович фон Шренк; 1826 – 8 January 1894) was a Russian zoologist, geographer and ethnographer. Biography Schrenck came from a Baltic German family, and was born and b ....

Cambaroides Japonicus
''Cambaroides japonicus'', also known as , is a species of crayfish endemic to Japan. They are small in size (6 cm) and grayish in color. Its front claws are much weaker than the American crayfish, which is an invasive species in Japan. The Japanese crayfish needs low temperature and high water purity, so they live in upper streams of rivers or lakes in highland regions. The distribution of Japanese crayfish comprises Hokkaidō and northern Tōhoku (the northern area of Honshū). The Environmental Agency (now Ministry of Environment) of Japan added it as a vulnerable species (IUCN category) to the Red Data List in 2000. It is thought that the causes of its decrease are corruption of water quality and the spread of the American crayfish '' Pacifastacus leniusculus'', which was imported in the 20th century and has steadily proliferated in northern Japan. Some suspect that this American crayfish carries some disease, such as the crayfish plague Crayfish plague (''Aphanomyc ...

Cambaridae
The Cambaridae are the largest of the four families of freshwater crayfish, with over 400 Species. Most of the species in the family are native the United States east of the Great Divide and Mexico, but fewer range north to Canada, and south to Guatemala and Honduras. Three live on the island of Cuba. The species in the genus ''Cambaroides'' are the only found outside North America, as they are restricted to eastern Asia. A few species, including the invasive ''Procambarus clarkii'' and '' Faxonius rusticus'', have been introduced to regions far outside their native range (both in North America and other continents). Conversely, many species have tiny ranges and are seriously threatened; a few are already extinct. A 2006 molecular study suggested that the family Cambaridae may be paraphyletic, with the family Astacidae Astacidae is a family of freshwater crayfish native to Europe and western North America. The family is made up of four extant (living) genera: The genera '' ...

Walter Faxon
Walter Faxon (February 4, 1848 – August 10, 1920) was an American ornithologist and carcinologist. He was born at Jamaica Plain, Massachusetts, where he grew up. He received three degrees from Harvard University. One of his greater ornithological achievements was demonstration that Brewster's warbler is a hybrid. He spent many years researching and classifying many American crayfish, including the genera ''Astacus'', ''Orconectes'', and ''Procambarus'', and contributed to at least 20 different scientific papers. Following a 2017 review, carried out by Oxford University, the former ''Faxonius'' subgenus of ''Orconectes'' was raised to a full genus as the subgenera were not monophyletic In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic gro .... The genus '' Faxonella'' is similarly named to ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Fresh Water
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh ...

Crayfish
Crayfish are freshwater crustaceans belonging to the clade Astacidea, which also contains lobsters. In some locations, they are also known as crawfish, craydids, crawdaddies, crawdads, freshwater lobsters, mountain lobsters, rock lobsters, mudbugs, baybugs or yabbies. Taxonomically, they are members of the superfamilies Astacoidea and Parastacoidea. They breathe through feather-like gills. Some species are found in brooks and streams, where fresh water is running, while others thrive in swamps, ditches, and paddy fields. Most crayfish cannot tolerate polluted water, although some species, such as ''Procambarus clarkii'', are hardier. Crayfish feed on animals and plants, either living or decomposing, and detritus. The term "crayfish" is applied to saltwater species in some countries. Terminology The name "crayfish" comes from the Old French word ' (Modern French '). The word has been modified to "crayfish" by association with "fish" (folk etymology). The largely American ...
