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 in fresh w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Majidae
Majidae is a family of crabs, comprising around 200 marine species inside 52 genera, with a carapace that is longer than it is broad, and which forms a point at the front. The legs can be very long in some species, leading to the name "spider crab". The exoskeleton is covered with bristles to which the crab attaches algae and other items to act as camouflage. Genera The roughly 200 extant and over 50 extinct species are divided among 52 genera in 5 subfamilies: '' Eurynolambrinae'' Števčić, 1994 *'' Eurynolambrus'' H. Milne-Edwards & Lucas, 1841 '' Majinae'' Samouelle, 1819 *'' Ageitomaia'' Griffin & Tranter, 1986 *'' Anacinetops'' Miers, 1879 *''Choniognathus'' Rathbun, 1932 *'' Cyclax'' Dana, 1851 *'' Entomonyx'' Miers, 1884 *''Eurynome'' Leach, 1814 *'' Jacquinotia'' Rathbun, 1915 *'' Kasagia'' Richer de Forges & Ng, 2007 *'' Kimbla'' Griffin & Tranter, 1986 *''Leptomithrax'' Miers, 1876 *'' Maiopsis'' Faxon, 1893 *'' Maja'' Lamarck, 1801 *'' Majella'' Ortmann, 1893 *'' M ...

Raffles Bulletin Of Zoology
''The Raffles Bulletin of Zoology'' is a peer-reviewed open-access scientific journal published by the Lee Kong Chian Natural History Museum at the National University of Singapore. It covers the taxonomy, ecology, and conservation of Southeast Asian fauna.Supplements are published as and when funding permits and may cover topics that extend beyond the normal scope of the journal depending on the targets of the funding agency. It was established as the ''Bulletin of the Raffles Museum'' in 1928 and renamed ''Bulletin of the National Museum of Singapore'' in 1961, before obtaining its current title in 1971.

Identification Species description This crustacean has a hard rounded-triangular shell, or carapace, that is covered in hair-like projections that vary in size. The shell's length is 1.3 times the size of its width, the shell's surface has many tubercles with spines running to the front of the shell going to the sides. The edges of the carapace have nine outward directed sharp spines: 3 supraorbital, 3 hepatic and 3 brachial. Two spines at the front of the crab's head form a V-shape and are covered with small bristles. Some of the bristles along the carapace are short and hooked while others are long and straight.
