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].
