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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scylla Serrata
''Scylla serrata'' (often called mud crab or mangrove crab, although both terms are highly ambiguous, and black crab) is an ecologically important species of crab found in the estuaries and mangroves of Africa, Australasia, and Asia. In their most common forms, their shell colours vary from a deep, mottled green to very dark brown. Distribution The natural range of ''S. serrata'' is in the Indo-Pacific. It is found from South Africa, around the coast of the Indian Ocean, where it is especially abundant in Sri Lanka, to the Southeast Asian Archipelago, as well as from southern Japan to south-eastern Australia, northern New Zealand, And as far east as Fiji and Samoa. The species has also been introduced to Hawaii and Florida. In Hawaii, mud crabs are colloquially known as Samoan crabs, as they were originally imported from American Samoa. As these crabs are known for their robust size and dense meat content, they have been greatly sought after over the years. As a result of ...

Scylla Tranquebarica
''Scylla tranquebarica'' is a species of mangrove crab in the genus ''Scylla''. ''Scylla tranquebarica'', one of several crabs known as the mud crab, is found in mangrove areas from Pakistan and Taiwan to the Malay Archipelago and other Indo-Pacific The Indo-Pacific is a vast biogeographic region of Earth. In a narrow sense, sometimes known as the Indo-West Pacific or Indo-Pacific Asia, it comprises the tropical waters of the Indian Ocean, the western and central Pacific Ocean, and the ... regions.

Scylla Paramamosain
''Scylla paramamosain'' is a mud crab commonly consumed in Southeast Asia. Distribution ''Scylla paramamosain'' is found along the coastlines of the South China Sea down to the Java Sea. It is now produced by aquaculture farms in southern Vietnam. Taxonomy ''Scylla paramamosain'' was described by Eulogio P. Estampador in 1949, as a subspecies of ''Scylla serrata''. It is now known that the crabs previously referred to as ''S. serrata'' in China China, officially the People's Republic of China (PRC), is a country in East Asia.

Scylla Olivacea
''Scylla olivacea'', commonly known as the orange mud crab, is a commercially important species of mangrove crab in the genus ''Scylla''. It is one of several crabs known as the mud crab and is found in mangrove areas from Southeast Asia to Pakistan, and from Japan to northern Australia. Along with other species in the genus ''Scylla'', it is widely farmed in aquaculture using wild-caught stocks. They can be differentiated from other species of ''Scylla'' by having blunted spines on the dorsal distal corner of the palm ( propodus) of the claw A claw is a curved, pointed appendage found at the end of a toe or finger in most amniotes (mammals, reptiles, birds). Some invertebrates such as beetles and spiders have somewhat similar fine, hooked structures at the end of the leg or tarsus ..., and by the rounded frontal lobe spines with shallow separations in between the eyes.

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.

Panopeus Herbstii
''Panopeus herbstii'' (the ''black-fingered mud crab'', ''black-clawed mud crab'', ''Atlantic mud crab'' or sometimes ''common mud crab'') is a true crab, belonging to the infraorder Brachyura, and is the largest of the mud crabs. ''Panopeus herbstii'' is small, growing to about 4 cm, with black-tipped claws of unequal size. ''P. herbstii'' has a strong exoskeleton, with very thick and strong claws. The shell is a dull gray and brown color. ''Panopeus herbstii'' is found along the Atlantic coast of North America, from Boston, Massachusetts to Santa Catarina, Brazil and on Bermuda. It is the most common xanthid crab on the east coast of the United States. It is found on muddy bottoms, where it takes refuge under stones and shells or among sponges and weeds, but it is rarely seen in the open. It feeds mainly on young clams, oysters, and periwinkles; it cracks open their shells with its strong claws. Mud crabs are especially fond of hermit crab Hermit crabs are anom ...

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'' G ...
