Tuerkayana Magnum
''Tuerkayana'' is a genus of large land crabs. It was created from two members of the genus ''Cardisoma'' and two members of ''Discoplax'' in late 2018 after a re-examination of the taxonomy of the family Gecarcinidae. Said re-examination also resulted in the creation of the new family Leptograpsodidae for the genus '' Leptograpsodes''. Species The genus ''Tuerkayana'' comprises these four species: * ''Tuerkayana celeste'' (Ng & Guinot, 2001) (formerly ''Discoplax'') * '' Tuerkayana hirtipes'' ( Dana, 1851) (formerly ''Cardisoma'') * '' Tuerkayana magnum'' (Ng & Shih, 2015) (formerly ''Discoplax'') * ''Tuerkayana rotundum'' (Quay & Gaimard, 1824) (formerly ''Cardisoma ''Cardisoma'' is a genus of large land crabs.

Land Crab
A number of lineages of crabs have evolved to live predominantly on land. Examples of terrestrial crabs are found in the families Gecarcinidae and Gecarcinucidae, as well as in selected genera from other families, such as ''Sesarma'', although the term "land crab" is often used to mean solely the family Gecarcinidae. Terrestriality and migration No clear distinction is made between "terrestrial", "semiterrestrial", and "aquatic" crabs. Rather, a continuum of terrestriality is displayed among the true crabs, although most land-adapted crabs must still return to water to release their eggs. Some species of terrestrial crabs can be found many kilometres from the sea, but have to complete annual migrations to the sea. For example, following the Indian Ocean monsoon, the Christmas Island red crab (''Gecarcoidea natalis'') migrates ', forming a "living carpet" of crabs. The crabs can travel up to in a day, and up to in total. Only a few land crabs, including certain '' Geosesar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cardisoma
''Cardisoma'' is a genus of large land crabs. Three species formerly placed in this genus are now placed in '' Discoplax''. The four species that remain in ''Cardisoma'' are found in warm coastal regions where they live in burrows. Young individuals are often very colourful with a purple-blue carapace and orange-red legs (leading to a level of popularity in the pet trade), but as they grow older the colours tend to fade, and females may be duller than males. Although less extreme than in fiddler crabs, one claw is usually considerably larger than the other. They are omnivore An omnivore () is an animal that has the ability to eat and survive on both plant and animal matter. Obtaining energy and nutrients from plant and animal matter, omnivores digest carbohydrates, protein, fat, and fiber, and metabolize the nutr ...s, but primarily feed on plant material.

Discoplax
''Discoplax'' is a genus of terrestrial crabs. It is very closely related to the genus ''Cardisoma''. Five species are currently recognised: *''Discoplax celeste'' 2012 *'' Discoplax gracilipes'' Ng & Guinot, 2001 *'' Discoplax longipes'' A. Milne-Edwards, 1867 *''Discoplax magna'' Ng & Shih, 2014 *''Discoplax michalis'' Ng & Shih, 2015 *''Discoplax rotunda'' (Quoy & Gaimard, 1824) See also * ''Tuerkayana'' – a genus which holds crabs formerly found in ''Discoplax'' and ''Cardisoma ''Cardisoma'' is a genus of large land crabs.

Gecarcinidae
The Gecarcinidae, the land crabs, are a family of true crabs that are adapted for terrestrial existence. Similar to all other crabs, land crabs possess a series of gills. In addition, the part of the carapace covering the gills is inflated and equipped with blood vessels. These organs extract oxygen from the air, analogous to the vertebrate lungs. Adult land crabs are terrestrial, but visit the sea periodically, where they breed and their larvae develop. Land crabs are tropical omnivores which sometimes cause considerable damage to crops. Most land crabs have one of their claws larger than the other. The family contains these genera: * ''Cardisoma'' * '' Discoplax'' * '' Epigrapsus'' * '' Gecarcinus'' * '' Gecarcoidea'' * '' Johngarthia'' * ''Tuerkayana'' See also *Sesarmidae, another family of terrestrial crabs *Coenobitidae The Coenobitidae are the family of terrestrial hermit crabs, widely known for their land-living habits as adults.

Danièle Guinot
Danièle Guinot (born 1933) is a French biologist, an emeritus professor at the Muséum national d'histoire naturelle in France, known for her research on crabs. Biography Guinot was born in eastern France and educated at the University of Montpellier and the University of Paris, finishing her studies in 1955. She then joined the Muséum national d'histoire naturelle as a research assistant; she remained there for the rest of her career. She earned a doctorate from Pierre and Marie Curie University in 1977. Research Guinot carried out several studies of crabs from exotic environments, including deep-sea crabs from the Indo-West Pacific bathyal zone and from hydrothermal vents, and crabs living in caves in Papua New Guinea. Her doctoral thesis proposed a new classification system for certain crabs based on the position of their reproductive organs. In later studies, she became particularly interested in crab behavior, including stridulation, carrying, and camouflage. Over the cou ...

Tuerkayana Hirtipes
''Tuerkayana hirtipes'' is a species of terrestrial crab. Description and behaviour ''T. hirtipes'' can be distinguished from members of the genus ''Discoplax'' by the smooth and distinctly inflated carapace. It is also blue or blue-brown in colour, compared to purple or purple-brown in the remaining species. The breeding season for ''T. hirtipes'' lasts seven months, and females must migrate to the sea to release their larvae. Distribution ''T. hirtipes'' has a wide distribution across the western Pacific Ocean. It has been recorded from southern Japan, Taiwan, southern China, Palau, Guam, eastern Australia, Fiji, Hawaii (a single record, almost certainly erroneous), the Solomon Islands, New Caledonia, the Philippines, Indonesia, Vietnam, Malaysia and Singapore. Records from the Indian Ocean are now considered to belong to two related species, '' T. celeste'' ( Christmas Island only) and '' D. magna'' (relatively widespread in eastern Indian Ocean).

James Dwight Dana
James Dwight Dana Royal Society of London, FRS FRSE (February 12, 1813 – April 14, 1895) was an American geologist, mineralogist, volcanologist, and zoologist. He made pioneering studies of mountain-building, volcano, volcanic activity, and the origin and structure of continents and oceans around the world. His zoological author abbreviation is Dana. Early life and career Dana was born February 12, 1813, in Utica, New York. His father was merchant James Dana (1780–1860) and his mother was Harriet Dwight (1792–1870). Through his mother he was related to the Dwight New England family of missionaries and educators including uncle Harrison Gray Otis Dwight and first cousin Henry Otis Dwight. He showed an early interest in science, which had been fostered by Fay Edgerton, a teacher in the Utica high school, and in 1830 he entered Yale College in order to study under Benjamin Silliman the elder. Graduating in 1833, for the next two years he was teacher of mathematics to midshi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
