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.[2] 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).[3][4]

An orange form of C. patzcuarensis is regularly seen in the freshwater aquarium trade.[5]

Species
Cambarellus patzcuarensis var. "Orange" is common in the aquarium trade, but it is rare in the wild where the species typically is dull gray-brown
Cambarellus shufeldtii, a relatively widespread species from the United States

The genus contains the following species:[6]

Subgenus Cambarellus (Cambarellus)
Subgenus Cambarellus (Pandicambarus)
gollark: It's not really a useful theory though. It makes no testable predictions.
gollark: Wouldn't you need unreasonably large amounts of trees/person to make that work?
gollark: I mean, yes, you *could* get a better one, but they could also be terrible and you couldn't do anything.
gollark: I don't see why you would expect monarchs, who have basically no checks on power, to do better than politicians, who at least are required to look good to some subset of the population.
gollark: (but doesn't lead directly to much faster computers because Dennard scaling is dead)
