Nanhaipotamon Macau
''Nanhaipotamon macau'', the Coloane hill crab, is a species of freshwater crab found solely in twelve hill streams on the island of Coloane in Macao. A member of the genus Nanhaipotamon, it was first described in December 2018 and is closely related to other land crabs such as '' Nanhaipotamon hongkongense''. Discovery A scientific study, commissioned by the Civic and Municipal Affairs Bureau of Macao and the University of New South Wales, was conducted in 2018 with the aim of surveying the freshwater crabs resident in the country of Macao and neighboring parts of China, as well as redescribing the Wuping Crab ('' Nanhaipotamon wupingense''), a closely related species of land crab whose original type specimen In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached.

Freshwater Crab
Around 1,300 species of freshwater crabs are distributed throughout the tropics and subtropics, divided among eight families. They show direct development and maternal care of a small number of offspring, in contrast to marine crabs, which release thousands of planktonic larvae. This limits the dispersal abilities of freshwater crabs, so they tend to be endemic to small areas. As a result, a large proportion are threatened with extinction. Systematics More than 1,300 described species of freshwater crabs are known, out of a total of 6,700 species of crabs across all environments. The total number of species of freshwater crabs, including undescribed species, is thought to be up to 65% higher, potentially up to 2,155 species, although most of the additional species are currently unknown to science. They belong to eight families, each with a limited distribution, although various crabs from other families are also able to tolerate freshwater conditions (euryhaline) or are second ...

Endemic Species
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coloane
Coloane (Cantonese: Lou Wan) is a former island in Macau that is united with the island of Taipa by an area of reclaimed land known as Cotai. It is located at the southern part of Macau. Administratively, the boundaries of the traditional civil parish ( pt, freguesia) of São Francisco Xavier are coterminous with that of Coloane. Etymology Coloane was known in Cantonese as ''Gau Ou Saan'' (九澳山 ''lit.'' "Nine-inlet Mountain" or transcribed in Portuguese as Ká-Hó) and ''Yim Jou Waan'' (鹽灶灣, ''lit.'' "Salt-stove Bay"). The Portuguese name "Coloane" is derived from the Cantonese pronunciation of ''Gwo Lou Waan'' (過路環, ''lit.'' "Passing-road Ring"). Geography Coloane has an area of , is long and is from the Macau Peninsula. The narrowest part of Coloane is . The highest points in Macau are eastern and central Coloane, with the highest point being the Coloane Alto (, Portuguese: Alto de Coloane). In the past, Coloane was separated from Taipa by the Seac Pai B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macao
Macau or Macao (; ; ; ), officially the Macao Special Administrative Region of the People's Republic of China (MSAR), is a city and special administrative region of China in the western Pearl River Delta by the South China Sea. With a population of about 680,000 and an area of , it is the most densely populated region in the world. Formerly a Portuguese colony, the territory of Portuguese Macau was first leased to Portugal as a trading post by the Ming dynasty in 1557. Portugal paid an annual rent and administered the territory under Chinese sovereignty until 1887. Portugal later gained perpetual colonial rights in the Sino-Portuguese Treaty of Peking. The colony remained under Portuguese rule until 1999, when it was transferred to China. Macau is a special administrative region of China, which maintains separate governing and economic systems from those of mainland China under the principle of " one country, two systems"..

Nanhaipotamon
''Nanhaipotamon'' is a genus of freshwater crabs, in the subfamily Potamiscinae, found in southern China and Taiwan. As of 2018, 18 species have been described. The genus is named after the South China Sea (; literally: 'South Sea'), for it occurs mostly in coastal areas. Description These crabs are relatively large, with a carapace breadth of up to . Depending on the species, the carapace may be vividly coloured, especially in males of '' N. hongkongense'' (orange to red),'''' '' N. aculatum'' (dark blue) and '' N. zhuhaiense'' (light blue). Chelipeds are usually unequal, more so in larger males, where one cheliped is relatively much larger than the other. This may be of use in territorial fights, as the crabs are very aggressive towards conspecifics.'''' Distribution and habitat Crabs of the genus ''Nanhaipotamon'' inhabit the banks of small to medium-sized hill streams, paddy fields and swamps. Although not particularly a lowland species, they usually do not occur abov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nanhaipotamon Hongkongense
''Nanhaipotamon hongkongense'' is a species of freshwater crab of the genus ''Nanhaipotamon'', known to occur in Hong Kong ( Hong Kong Island, New Territories, Lantau Island and a few smaller islands) and adjacent areas in Shenzhen and Dongguan, Mainland China. Description and life history ''Nanhaipotamon hongkongense'' is a burrowing species that digs burrows into muddy banks of small rivers and creeks or moist soil. It is a nocturnal species that mostly stays in its burrow during the day and comes out at night or after heavy rainfalls. Offspring hatch as miniature versions of adult crabs after direct development, like with all potamid crabs. Distribution and habitat This species is semiterrestrial and inhabits the banks of hillstreams, but can also be found in places far away from running water, such as moist areas were groundwater seeps through the soil, generally in secondary evergreen broadleaf forests. Whereas adults are rarely reported from actual aquatic habitats, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or ...

Nanhaipotamon Wupingense
''Nanhaipotamon wupingense'', the Wuping crab, is a species of freshwater crab in the genus ''Nanhaipotamon'', known only to inhabit the locality of Xiaba in Wuping County, Fujian Province, China, and formerly believed to have a disjunct population in Macao. First described in 2003, the type specimen was subsequently lost, and with the crab not having been described initially in sufficient detail, an effort was made in 2018 to redescribe the species using a specimen collected in Macao. This study, however, concluded that the Macao population was actually a different species, ''Nanhaipotamon macau ''Nanhaipotamon macau'', the Coloane hill crab, is a species of freshwater crab found solely in twelve hill streams on the island of Coloane in Macao.

Type Specimen
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost ...

Taxa Named By Shane T
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in '' Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
