Astacidae is a family of freshwater crayfish native to Europe, western Asia and western North America. The family is made up of four extant (living) genera: The genera Astacus (which includes the European crayfish), Pontastacus (which includes the Turkish crayfish), and Austropotamobius are all found throughout Europe and parts of western Asia, while Pacifastacus (which includes the signal crayfish) is native to western United States and British Columbia, but has also been introduced elsewhere.
