Jean René Constant Quoy
Jean René Constant Quoy (10 November 1790 in Maillé, Vendée, Maillé – 4 July 1869 in Rochefort, Charente-Maritime, Rochefort) was a French naval surgeon, zoologist and anatomist. In 1806, he began his medical studies at the school of naval medicine at Rochefort, Charente-Maritime, Rochefort, afterwards serving as an auxiliary-surgeon on a trip to the Antilles (1808–1809). After earning his medical doctorate in 1814 at Montpellier, he was surgeon-major on a journey to Réunion (1814–1815). Along with Joseph Paul Gaimard, he served as naturalist and surgeon aboard the ''Uranie'' under Louis de Freycinet from 1817 to 1820, and on the ''French ship Astrolabe (1817), Astrolabe'' (1826–1829) under the command of Jules Dumont d'Urville. In July 1823 he and Gaimard presented a paper to the Académie royale des Sciences on the origin of coral reefs, taking issue with the then widespread belief that these were constructed by coral polyps from bases in very deep water and arguin ...

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.

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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.

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Grapsoidea
The Grapsoidea are a superfamily of crabs; they are well known and contain many taxa which are terrestrial (land-living), semiterrestrial (taking to the sea only for reproduction), or limnic (living in fresh water). Another well-known member with a more conventional lifestyle is the Chinese mitten crab, ''Eriocheir sinensis''. The delimitation of the Grapsidae and Plagusiidae is in need of revision; the latter at least is not monophyletic. The same apparently holds true for several genera in the Sesarmidae. The closest living relatives of the Grapsoidea are the Ocypodoidea The Ocypodoidea, or ocypoid crabs, are a superfamily of crabs, named after the genus '' Ocypode''. It contains over 300 extant species in these eight families: * Camptandriidae Stimpson, 1858 * Dotillidae Stimpson, 1858 * Heloeciidae H. Miln .... In fact, they seem to be paraphyletic with respect to each other and it seems warranted to merge the Ocypodoidea into the Grapsoidea. References Exter ...

Terrestrial Crustaceans
Terrestrial refers to things related to land or the planet Earth. Terrestrial may also refer to: * Terrestrial animal, an animal that lives on land opposed to living in water, or sometimes an animal that lives on or near the ground, as opposed to arboreal life (in trees) ** A fishing fly that simulates the appearance of a land insect is referred to as a terrestrial fly. * Terrestrial ecoregion, land ecoregions, as distinct from freshwater ecoregions and marine ecoregions * Terrestrial ecosystem, an ecosystem found only on landforms * Terrestrial gamma-ray flash, a burst of gamma rays produced in Earth's atmosphere * Terrestrial locomotion, evolutionary adaptation from aquatic types of locomotion * Terrestrial plant, a plant that grows on land rather than in water or on rocks or trees * Terrestrial planet, a planet that is primarily composed of silicate rocks, and thus "Earth-like" * Terrestrial radio, radio signals received through a conventional aerial, as opposed to satellite ...
