Red Swamp Crayfish (Procambarus clarkii)

Arthropoda > Crustacea > Malacostraca > Decapoda > Pleocyemata > Astacidea > Cambaridae

Native to the southeastern United States and an introduced species in California, perhaps the most commonly recorded crayfish species in Southern California. California's only native crayfish species - the Shasta Crayfish - is not found in Southern California, and as such all crayfish that may be encountered in Southern California are introduced species.
