Trichodactylidae is a family of crabs, in its own superfamily, Trichodactyloidea. They are all freshwater animals from Central and South America, including some offshore islands, such as Ilhabela, São Paulo. Only one of the 50 species is known from the fossil record, '' Sylviocarcinus piriformis'' from the Miocene of Colombia. The family contains 15 genera in two subfamilies: ;Subfamily Dilocarcininae Pretzmann, 1978 *'' Bottiella'' Magalhães & Türkay, 1996 *'' Dilocarcinus'' H. Milne-Edwards, 1853 *'' Forsteria'' Bott, 1969 *'' Fredilocarcinus'' Pretzmann, 1978 *'' Goyazana'' Bott, 1969 *'' Melocarcinus'' Magalhães & Türkay, 1996 *'' Moreirocarcinus'' Magalhães & Türkay, 1996 *'' Poppiana'' Bott, 1969 *'' Rotundovaldivia'' Pretzmann, 1968 *'' Sylviocarcinus'' H.

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] |
