King crabs, also called stone crabs, are a family of crab-like decapod crustaceans chiefly found in cold seas. Because of their large size, many species are widely caught and sold as food.

King crabs are generally believed to be derived from hermit crab ancestors, which may explain the asymmetry still found in the adult forms. Although some doubt still exists about this theory, king crabs are the most widely quoted example of carcinisation (shellification/crustification) among the Decapoda (familiar crustaceans). The evidence for this explanation comes from the asymmetry of the king crab's abdomen, which is thought to reflect the asymmetry of hermit crabs, which must fit into a spiral shell.

Lithodes

Lithodes aequispinus

The golden king crab, Lithodes aequispinus, is caught in the Aleutian Chain off the coast of Alaska. The golden king crab is significantly smaller than the red and blue king crabs, averaging 5–8 lb (2–4 kg) ^[3]. It tastes similar to the red and blue king crabs, though perhaps somewhat sweeter. They are considerably cheaper due to their appearance and size.

The red king crab, Paralithodes camtschaticus, is a very large species, sometimes reaching a carapace width of 11 in (28 cm) and a leg span of 6 ft (1.8 m). Its natural range is the Bering Sea, between the Aleutian Islands and St. Lawrence Island.
