Cambarus asperimanus
mitten crayfish
Cambarus asperimanus, commonly known as the mitten crayfish, is a species of freshwater crayfish in the family Cambaridae. It was first described by Faxon in 1914 and is native to North America. The species holds a Least Concern conservation status according to the IUCN, last reviewed in 2010.

Cambarus dubius
Upland Burrowing Crayfish
Cambarus dubius, commonly known as the Upland Burrowing Crayfish, is a burrowing crayfish species native to the central and southern Appalachian region of the eastern United States. The species has a complex taxonomic history with multiple distinct color phases historically recognized across different geographic areas. Recent taxonomic work has restricted C. dubius sensu stricto to populations with orange dorsal and lateral coloration and cream ventral surfaces, found in the central and northern Allegheny Mountains and high elevations of the Appalachian Plateau. The species constructs distinctive burrow systems and faces conservation concerns due to limited distribution data and habitat alterations.

Cambarus robustus
Big Water Crayfish, robust crayfish
Cambarus robustus, commonly known as the Big Water Crayfish or robust crayfish, is a freshwater crayfish species in the family Cambaridae. It is native to eastern North America, ranging from several U.S. states to Ontario, Canada. The species has been studied extensively as a surrogate for federally endangered crayfish species due to its close phylogenetic relationships and similar ecological requirements. Research indicates it demonstrates significant acid tolerance compared to sympatric Orconectes species, exhibits complex agonistic behaviors with distinct initiation acts predicting contest outcomes, and occupies a partitioned trophic position in multi-species crayfish communities.

Cambarus speciosus
Beautiful Crayfish
Cambarus speciosus, commonly known as the beautiful crayfish, is a species of freshwater crayfish in the family Cambaridae. It is endemic to Georgia, United States. The species is currently listed as Near Threatened (NT) by the IUCN, with a stable population as of the last review in 2010. The specific epithet 'speciosus' refers to its attractive appearance.

Cambarus tartarus
Oklahoma Cave Crayfish
Cambarus tartarus is a critically endangered cave-dwelling crayfish endemic to two caves in Delaware County, Oklahoma. Described in 1972, this species has one of the most restricted ranges of any North American crayfish. The IUCN assessed it as Critically Endangered in 2010, noting an extremely high risk of extinction in the immediate future due to its tiny geographic range and vulnerability to groundwater contamination.

Faxonius luteus
Golden Crayfish
Faxonius luteus, commonly known as the Golden Crayfish, is a freshwater crustacean in the family Cambaridae. It is native to North America, with documented presence in the United States. The species was first described by Creaser in 1933. Like other members of the genus Faxonius, it inhabits freshwater environments. The specific epithet "luteus" refers to its golden or yellowish coloration.

Faxonius palmeri is a freshwater crayfish in the family Cambaridae, commonly known as the Gray-speckled Crayfish. It was originally described as Cambarus palmeri by Faxon in 1884 and later transferred to the genus Faxonius. The species is native to North America, with documented occurrences in the United States.

Lacunicambarus diogenes
devil crayfish, devil crawfish
Lacunicambarus diogenes, commonly known as the devil crayfish or devil crawfish, is a primary burrowing crayfish native to eastern North America. This species constructs and inhabits burrows in wet, muddy terrestrial habitats rather than living in permanent surface water. Its burrowing activities create refugia used by numerous other species, including documented use by eastern cicada killer wasps (Sphecius speciosus) as brooding habitat. The species ranges across the Atlantic Coastal Plain and Piedmont ecoregion from New Jersey to Georgia, with disjunct populations in Louisiana.

Northern Clearwater Crayfish
Orconectes propinquus, commonly known as the Northern Clearwater Crayfish, is a freshwater crayfish species in the family Cambaridae. It is native to northern North American clearwater habitats and has been the subject of ecological and physiological research comparing it to other crayfish species. The species shows specific habitat preferences for water depth, velocity, substrate type, and cover availability. It is sensitive to low pH conditions compared to some co-occurring crayfish species.

Orconectes validus is a species of freshwater crayfish in the family Cambaridae. The name is currently treated as a synonym of Faxonius validus. Original description dates to 1914 by Faxon. As a synonym, biological information specific to this nominal taxon is limited and may be conflated with the accepted name.

Procambarus fallax
Slough Crayfish, Deceitful Crayfish
Procambarus fallax is a freshwater crayfish native to peninsular Florida and southern Georgia, USA, where it inhabits tributaries of the Satilla River. The species is notable as the sexual parental species of the parthenogenetic Marmorkrebs (marbled crayfish), which originated as a single lineage from P. fallax through apomictic parthenogenesis. While P. fallax reproduces sexually with separate males and females, its parthenogenetic derivative has achieved global distribution through the aquarium trade and exhibits high invasive potential due to single-female founding capability.
