Glyptolithodes
''Glyptolithodes cristatipes'', also known as the Peruvian centolla, is a species of king crab, and the only species in the genus ''Glyptolithodes''. The species was briefly placed in the related genus ''Rhinolithodes'' after its initial alpha taxonomy, description, but was soon moved to its own genus. Distribution ''G. cristatipes'' is found off the Pacific Ocean, Pacific coasts of South America, especially Chile and Peru, and extending as far northwards as Southern California, and as far south as 33° 35' S. The most closely related genera to ''Glyptolithodes'' all live in the Northern Hemisphere, suggesting that ''Glyptolithodes'' has migrated from its ancestral home to the Southern Hemisphere, where it is now most abundant. Dimorphism This species shows notable sexual dimorphism, with the males having a right cheliped which is larger than the left.

King Crab
King crabs are a taxon of decapod crustaceans 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, the most common being the red king crab (''Paralithodes camtschaticus''). King crabs are generally thought to be derived from hermit crab-like 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. 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. Controversial taxon Although formerly classified among the hermit crabs in the superfamily Paguroidea, king crabs are now placed in a ...
