    • King crabs are a taxon of decapod crustaceans that are chiefly found in cold seas. Because of their large size and the taste of their meat, many species are widely caught and sold as food with the most common being the red king crab (Paralithodes camtschaticus).

      King crabs are generally thought to be derived from hermit crab ancestors within the Paguridae, which may explain the asymmetry still found in the adult forms. This ancestry is supported by several anatomical peculiarities which are present only in king crabs and hermit crabs. Although some doubt still exists about this hypothesis, king crabs are the most widely quoted example of carcinisation among the Decapoda.[1] 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.

    • Alaskan king crab fishing is carried out during the fall in the waters off the coast of Alaska and the Aleutian Islands. The commercial catch is shipped worldwide. Large numbers of king crab are also caught in Russian and international waters.

      In 1980, at the peak of the king crab industry, Alaskan fisheries produced up to of crab. However, by 1983, the total size of the catch had dropped by up to 90% in some places. [2] Several theories for the precipitous drop in the crab population have been proposed, including overfishing, warmer waters, and increased fish predation. As a result, the current season is very short and in the 2010 season, only of red king crab were landed. Alaskan crab fishing is very dangerous, and the fatality rate among the fishermen is about 80 times the fatality rate of the average worker. It is suggested that, on average, one crab fisherman dies weekly during the seasons.[3]
