Xanthoidea
Xanthoidea is a superfamily of crabs, comprising the three families Xanthidae, Panopeidae and Pseudorhombilidae. Formerly, a number of other families were included in Xanthoidea, but many of these have since been removed to other superfamilies. These include Carpilioidea, Eriphioidea, Hexapodoidea, Pilumnoidea and Trapezioidea. Even in this reduced state, Xanthoidea remains one of the most species-rich superfamilies of crabs. Families The World Register of Marine Species lists the following families: *Panopeidae Ortmann, 1893 * Pseudorhombilidae Alcock, 1900 *Xanthidae Xanthidae is a family of crabs known as gorilla crabs, mud crabs, pebble crabs or rubble crabs.

Crabs
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 in fresh w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pilumnoidea
Pilumnoidea is a superfamily of crabs, whose members were previously included in the Xanthoidea. The three families are unified by the free articulation of all the segments of the male crab's abdomen and by the form of the gonopods. The earliest fossils assigned to this group are of Eocene age. Classification Pilumnidae is by far the largest of the three families, with 73 of the 78 genera: ; Pilumnidae Samouelle, 1819 * Subfamily Calmaniinae Števčić, 1991 ** '' Calmania'' Laurie, 1906 * Subfamily Pilumninae Samouelle, 1819 ** '' Actumnus'' Dana, 1851 ** '' Aniptumnus'' Ng, 2002 ** '' Bathypilumnus'' Ng & L.

Trapezioidea
Trapezioidea is a superfamily (zoology), superfamily of crabs. Its members live symbiosis, symbiotically with corals, and have a fossil record stretching back to the Eocene.

Xantho Poressa
''Xantho poressa'', the jaguar round crab, is a species of crab from the eastern Atlantic Ocean. It is one of four species in the genus ''Xantho''. Description The juveniles of ''X. poressa'' are cryptically coloured as camouflage among the epibionts on the leaves of ''Posidonia'' with a variable carapace colour, which can be yellowish, reddish, brown, or dark grey with patches of another colour, usually white. The pereiopods are usually banded with dark brown or black bands alternating with white or translucent stripes or spots, although the fifth pereiopod is brighter and often unmarked. The adults are uniformly dark grey in colour and they leave the seagrass beds for more open, rocky substrates. Distribution ''X. poressa'' is distributed throughout the Black Sea and the Mediterranean Sea and into the warmer parts of the north eastern Atlantic to the Canary Islands. Biology The larvae of ''X. poressa'' go through four zoeal and one megalopal stages, which are typical of most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Panopeidae
The Panopeidae are a family containing 26 genera of morphologically similar crabs, often known as "mud crabs". Their centers of diversity are the Atlantic Ocean and eastern Pacific Ocean. Distribution Most members of the family Panopeidae live in the Atlantic Ocean or eastern Pacific Ocean. Only one species occurs in Australian waters – '' Homoioplax haswelli''. Ecology The various genera of the Panopeidae are morphologically similar, partly as a result of many instances of convergent evolution to similar habitats and food preferences. Crabs of the family Panopeidae are all free-living (not commensal or parasitic), and typically live in soft-bottomed parts of the ocean, lending them the common name "mud crabs" (a name also shared by other organisms). They burrow into the sediment and feed on a variety of marine invertebrates.

Xanthidae
Xanthidae is a family of crabs known as gorilla crabs, mud crabs, pebble crabs or rubble crabs. Xanthid crabs are often brightly coloured and are highly poisonous, containing toxins which are not destroyed by cooking and for which no antidote is known. The toxins are similar to the tetrodotoxin and saxitoxin produced by puffer fish, and may be produced by bacteria in the genus ''Vibrio'' living in symbiosis with the crabs, mostly '' V. alginolyticus'' and '' V. parahaemolyticus''. Classification Many species formerly included in the family Xanthidae have since been moved to new families. Despite this, Xanthidae is still the largest crab family in terms of species richness, with 572 species in 133 genera divided among the thirteen subfamilies: * Actaeinae Alcock, 1898 **'' Actaea'' De Haan, 1833 **'' Actaeodes'' Dana, 1851 **'' Actaeops'' † Portell & Collins, 2004 **'' Allactaea'' Williams, 1974 **'' Epiactaea'' Serène, 1984 **'' Epiactaeodes'' Serène, 1984 **''Forestia'' Gu ...

William Sharp Macleay
William Sharp Macleay or McLeay (21 July 1792 – 26 January 1865) was a British civil servant and entomologist. He was a prominent promoter of the Quinarian system of classification. After graduating, he worked for the British embassy in Paris, following his interest in natural history at the same time, publishing essays on insects and corresponding with Charles Darwin. Macleay moved to Havana, Cuba, where he was, in turn, commissioner of arbitration, commissary judge, and then judge. Retiring from this work, he emigrated to Australia, where he continued to collect insects and studied marine natural history. Early life Macleay was born in London, eldest son of Alexander Macleay, who named him for his then business partner, fellow wine merchant William Sharp. He attended Westminster School and Trinity College, Cambridge, graduating with honours in 1814. He was then appointed attaché to the British embassy at Paris, and secretary to the board for liquidating British claims on ...
