Cambarus bartonii is a species of crayfish native to eastern North America, where it is called the common crayfish[1] or Appalachian brook crayfish.[2]
C. bartonii was the first crayfish to be described from North America, when Johan Christian Fabricius published it under the name Astacus Bartonii in his 1798 work Supplementum entomologiae systematicae.[3] The locality where his specimen was captured is not known, but is thought to be near Philadelphia, Pennsylvania.[1]
C. bartonii lives in fast–flowing, cool, rocky streams as well as shallow lakes,[4] and is found in the Canadian provinces of Ontario, Quebec and New Brunswick, and in the United States from Maine to Alabama.[2] In the south of its range, C. bartoni is restricted to the Appalachian Mountains and their foothills.[1]
Colouration is usually plain dark brown, although mottling is occasionally seen, as is a saddle-shaped marking.[5]
Several subspecies of C. bartonii have been recognised, but it is unclear how advisable this is, and work is ongoing to determine patterns of infraspecific variation.[6]
Cambarus bartonii is included as a species of Least Concern on the IUCN Red List.[7]
