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.

Cambarellus
''Cambarellus'' is a genus of small freshwater crayfish in the family Cambaridae. The 19 species are found in Mexico (subgenus ''Cambarellus'') and the Gulf States of the United States (subgenus ''Pandicambarus''). Among the Mexican species, ''C. areolatus'', ''C. patzcuarensis'', and ''C. prolixus'' are considered seriously threatened by the IUCN, and ''C. alvarezi'' is already extinct. ''C. chihuahuae'' was also believed to be extinct until rediscovered in 2012. ''C. alvarezi'' and four undescribed, extinct ''Cambarellus'' species were restricted to desert spring systems in southwestern Nuevo León; each one shared its habitat with a ''Cyprinodon'' pupfish (these are also fully extinct or extinct in the wild). An orange form of ''C. patzcuarensis'' is regularly seen in the freshwater aquarium trade. Species The genus contains the following species: ;Subgenus ''Cambarellus (Cambarellus)'' *†''Cambarellus alvarezi'' (Villalobos, 1952)Villalobos, A. (1952). Estudios de los ...

Procambarus
''Procambarus'' is a genus of crayfish in the family Cambaridae, all native to North and Central America. It includes a number of troglobitic species, and the marbled crayfish (''marmorkrebs''), which is parthenogenetic. Originally described as a subgenus for four species, it now contains around 161 species. Biogeography The majority of the diversity is found in the southeastern United States, but the genus extends as far south as Guatemala and Honduras, and on the Caribbean island of Cuba. After United States, the highest diversity is in Mexico with about 45 species. Only two are native to Guatemala (''P. pilosimanus'' and ''P. williamsoni''), one to Belize (''P. pilosimanus''), one to Honduras (''P. williamsoni'') and three to Cuba (''P. atkinsoni'', ''P. cubensis'' and ''P. niveus''). Subgenus ''Ortmannicus'' was the most widespread, with the range of ''Procambarus acutus'' extending as far north as the Great Lakes and New England, as well as south into northeastern Mexico; ...

Cambarus
''Cambarus'' is a large and diverse genus of crayfish from the United States and Canada. The adults range in size from about 5 centimeters (2 in) up to approximately 15 centimeters (6 in). Description The genus ''Cambarus'' is the second largest freshwater crayfish genus inhabiting the Northern Hemisphere, with only sixty fewer species than the genus ''Procambarus''. Though ''Cambarus'' are varied across species, the two terminal elements that make up the male form I gonopod form ninety degree angles with the central appendage, allowing for their identification. Unlike the genus ''Procambarus'' whose first pleopod tends to have three processes at the tip, ''Cambarus'' has only one or two. ''Cambarus'' reach 17–26 mm carapace lengths in their first year, while average adult carapace length ranges from 55–62 mm. As a genus containing nearly 100 species, ''Cambarus's'' coloration is variable. '' Cambarus bartonii'' is dark brown, while species like '' Cam ...

Faxonius
''Faxonius'' is a genus of freshwater crayfish in the family Cambaridae. There are more than 90 described species in ''Faxonius''. It includes the rusty crayfish, an invasive species in North America, and three species, ''F. virilis'', ''F. immunis'', and ''F. limosus'', that are invasive to Europe. This genus was formerly considered a subgenus of ''Orconectes''. Several former ''Orconectes'' species were added to this genus in 2017, leaving only the cave dwelling species unchanged, however ''F. stygocanei'' was reallocated, even though it lives in caves. Species These species belong to the genus ''Faxonius'': * '' Faxonius acares'' ( Fitzpatrick, 1965) * '' Faxonius alabamensis'' ( Faxon, 1884) * '' Faxonius alluvius'' (Simon & McMurray, 2014) * ''Faxonius barrenensis'' (Rhoades, 1944) * '' Faxonius bellator'' (Bloom, McCall, Schuster & Blanton, 2019) * '' Faxonius bisectus'' (Rhoades, 1944) * '' Faxonius burri'' (Taylor & Sabaj, 1998) * ''Faxonius carolinensis'' (Cooper & C ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fallicambarus
''Fallicambarus'' is a genus of crayfish in the family Cambaridae from the United States and Canada. It includes 12 species, of which one is on the IUCN Red List as a vulnerable species (VU) and one as an endangered species (EN). The species of this genus are all restricted to three states or fewer, from Texas and Oklahoma east to Florida. The subgenus Creaserinus formerly contained eight additional species of ''Fallicambarus'', but has been elevated in rank to genus, resulting in the transfer of those species from ''Fallicambarus'' to ''Creaserinus''. Species These twelve species are members of the genus ''Fallicambarus''. *'' Fallicambarus devastator'' (Hobbs & Whiteman, 1987) – Texas *'' Fallicambarus dissitus'' (Penn, 1955) (Pine Hills Digger) – Arkansas, Louisiana *''Fallicambarus harpi ''Fallicambarus harpi'', the Ouachita burrowing crayfish, is a species of crayfish in the family Cambaridae The Cambaridae are the largest of the four families of freshwater c ...

Lacunicambarus
''Lacunicambarus'' is a genus of burrowing crayfishes in the family Cambaridae. There are currently 12 described species in ''Lacunicambarus'', all of which are found east of the Continental Divide in North America. The genus was first recognized in 2018 when it was discovered through genetic analyses that the ''Cambarus'' subgenera ''Lacunicambarus'' and ''Tubericambarus'' were not monophyletic on their own, but that when combined they formed a single monophyletic group distinct from ''Cambarus''. A 2022 study used anchored hybrid enrichment to resolve the ''Lacunicambarus'' phylogeny, which elucidated interspecific relationships and highlighted remaining undescribed diversity within the genus. Species ''Lacunicambarus'' contains the following 12 species, plus 2 currently undescribed species: * '' Lacunicambarus acanthura'' (Hobbs, 1981) (Thornytail Crayfish) * '' Lacunicambarus chimera'' Glon & Thoma, 2019 (Crawzilla Crawdad) * '' Lacunicambarus dalyae'' Glon, Williams & Loughma ...

Procambarus Clarkii
''Procambarus clarkii'', known variously as the red swamp crayfish, Louisiana crawfish or mudbug, is a species of cambarid crayfish native to freshwater bodies of northern Mexico, and southern and southeastern United States, but also introduced elsewhere (both in North America and other continents), where it is often an invasive pest. Appearance ''P. clarkii'' is typically dark red, with long claws and head, small or no spines on the sides of its carapace just below the head, and rows of bright red bumps on the front and side of the first leg. Range and range expansion The native range of ''P. clarkii'' is from northern Mexico and far southeastern New Mexico, through the Gulf States to the Florida Panhandle, as well as inland north through the Mississippi Basin to southern Illinois and Ohio. It has also been introduced, sometimes deliberately, outside its natural range to countries in Asia, Africa, Europe and elsewhere in the Americas. In northern Europe, the populations ar ...
