Cancroidea
Cancroidea is a superfamily of crabs, comprising the families Atelecyclidae and Cancridae. http://boletinsgm.igeolcu.unam.mx/bsgm/vols/epoca04/6502/%2810%29Osso.pdf Four other families have been separated into new superfamilies: Cheiragonidae into Cheiragonoidea, Corystidae into Corystoidea, and both Pirimelidae and Thiidae Thiidae is a family of crabs in the crustacean order Decapoda. Genera The family contains two genera in two subfamilies: * Subfamily Nautilocorystinae Ortmann, 1893 ** '' Nautilocorystes'' Milne Edwards, 1837 * Subfamily Thiinae Dana, 1852 ... into Portunoidea. Montezumellidae has been moved from Cancroidea to his own Superfamily Montezumelloidea Ossó & Domínguez, 2019 (Zootaxa, 4623 (1): 175–188). References Crabs Arthropod superfamilies {{crab-stub ...

Atelecyclidae
Atelecyclidae is a family of crabs belonging to the superfamily Cancroidea, and currently contains eight genera of which two are extinct. However, the genera other than ''Atelecyclus'' and '' Pseudocorystes'' do not belong in the Cancroidea, and are to be removed from the family. *''Atelecyclus'' *† '' Levicyclus'' *† '' Palaeotrichia'' *''Peltarion Peltarion is an AI software company with offices in Stockholm and London.

Cancer Pagurus
''Cancer pagurus'', commonly known as the edible crab or brown crab, is a species of crab found in the North Sea, North Atlantic Ocean, and perhaps the Mediterranean Sea. It is a robust crab of a reddish-brown colour, having an oval carapace with a characteristic "pie crust" edge and black tips to the claws. A mature adult may have a carapace width up to and weigh up to . ''C. pagurus'' is a nocturnal predator, targeting a range of molluscs and crustaceans. It is the subject of the largest crab fisheries, crab fishery in Western Europe, centred on the coasts of the British Isles, with more than 60,000 tonnes caught annually. Description The carapace of ''C. pagurus'' adults is a reddish-brown colour, while in young specimens it is purple-brown. It occasionally bears white patches, and is shaped along the front edge into nine rounded lobes, resembling a pie crust. Males typically have a carapace long, and females long, although they may reach up to long in exceptional ca ...

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. Environment Crabs are found in all of the world's oceans, as well as i ...

Pierre André Latreille
Pierre André Latreille (; 29 November 1762 – 6 February 1833) was a French zoology, zoologist, specialising in arthropods. Having trained as a Roman Catholic priest before the French Revolution, Latreille was imprisoned, and only regained his freedom after recognising a rare beetle species he found in the prison, ''Necrobia ruficollis''. He published his first important work in 1796 (), and was eventually employed by the . His foresighted work on arthropod systematics and Taxonomy (biology), taxonomy gained him respect and accolades, including being asked to write the volume on arthropods for George Cuvier's monumental work, , the only part not by Cuvier himself. Latreille was considered the foremost entomology, entomologist of his time, and was described by one of his pupils as "the prince of entomologists". Biography Early life Pierre André Latreille was born on 29 November 1762 in the town of Brive-la-Gaillarde, Brive, then in the Limousin (province), province of Limo ...

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.
