Corystidae

	Corystidae Corystidae is a family of crabs, in its own superfamily, Corystoidea. It includes what was once thought to be the oldest Eubrachyuran fossil, '' Hebertides jurassica'', thought to be dating from the Bathonian (Middle Jurassic); the species was subsequently reinterpreted as being Cenozoic in age. Corystidae contains ten extant and five extinct species in eight genera: ''Corystes'' Bosc, 1802 '' Corystites'' Lőrenthey, in Lőrenthey & Beurlen, 1929 '' Gomeza'' Gray, 1831 '' Gomezinus'' † Collins, Lee & Noad, 2003 '' Harenacorystes'' † Van Bakel, Jagt, Artal & Fraaije, 2009 '' Hebertides'' † Guinot, De Angeli & Garassino, 2007 ''Jonas Jonas may refer to: Geography Jonas, Netherlands, Netherlands * Jonas, Pennsylvania, United States * Jonas Ridge, North Carolina, United States People with the name * Jonas (name), people with the given name or surname Jonas * Jonas, one of ...''

picture info	Crab Crabs are decapod crustaceans of the infraorder Brachyura, which typically have a very short projecting "tail" (abdomen) ( el, βραχύς , translit=brachys = short, / = tail), usually hidden entirely under the thorax. They live in all the world's oceans, in freshwater, and on land, are generally covered with a thick exoskeleton, and have a single pair of pincers. They first appeared during the Jurassic Period. Description Crabs are generally covered with a thick exoskeleton, composed primarily of highly mineralized chitin, and armed with a pair of chelae (claws). Crabs vary in size from the pea crab, a few millimeters wide, to the Japanese spider crab, with a leg span up to . Several other groups of crustaceans with similar appearances – such as king crabs and porcelain crabs – are not true crabs, but have evolved features similar to true crabs through a process known as carcinisation.

	Corystes Cassivelaunus ''Corystes cassivelaunus'', the masked crab, helmet crab or sand crab, is a burrowing crab of the North Atlantic and North Sea from Portugal to Norway, which also occurs in the Mediterranean Sea. It may grow up to long (carapace length). The name "masked crab" derives from the patterns on the carapace which resemble a human face (a case of pareidolia), in a similar manner to ''heikegani''. It is the only species in the genus ''Corystes''. ''C. cassivelaunus'' lives buried in sandy substrates, where it feeds on the infaunal invertebrates such as polychaete worms and bivalve molluscs. It uses its two antennae to form a breathing tube that allows oxygenated water down into the substrate. The cheliped A chela ()also called a claw, nipper, or pinceris a pincer-like organ at the end of certain limbs of some arthropods. The name comes from Ancient Greek , through New Latin '. The plural form is chelae. Legs bearing a chela are called chelipeds. ...s of males are much longer than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
