	6: Distribution and AEtiology, The Crayfish, T. H. Huxley, 1879
		Astacus torrentium appears to be particularly addicted to rapid highland streams and the turbid pools which they feed.
		Astacus nobilis is indigenous to France, Germany, and the Italian peninsula.
		Astacus torrentium, as we have seen, inhabits both the British Islands and the continent of Europe; nevertheless, there is every reason to believe that twenty miles of sea water is an insuperable barrier to the passage of crayfishes from one land to the other.

		Astacus, Astacus astacus (Linnaeus, 1758) / Astacus fluviatilis (Fabricius, 1775) / Astacus leptodactylus (Eschscholtz, 1823), is a genus of crayfish.
		Due to the American crayfish plague, crayfish of this genus have been almost wiped out in Europe and have in many European countries been replaced by the North American Signal crayfish, which is resistant to the plague.
		In Europe, and in particular in Scandinavia, Astacus is often considered to be the original and finer, thus more expensive, crayfish.

		Astacus astacus, Austropotamobius pallipes, Austropotamobius torrentium and Astacus leptodactylus are examples of European species that are susceptible to the disease.

		It is found from France throughout central Europe, to the Balkan peninsula, and north as far as parts of the British Isles, Scandinavia, and western parts of the former Soviet Union.
		Astacus astacus is susceptible to the crayfish plague carried by the invasive American species Pacifastacus leniusculus, and is therefore listed as "vulnerable" by the IUCN Red List of Threatened Species.
