Rhinogobius Candidianus
''Rhinogobius candidianus'' is a species of freshwater goby. It is endemic to Taiwan. Etymology The specific name ''candidianus'' refers to the type locality, Lake Candidius. However, the species does not occur in the lake itself, but rather in the nearby rivers. Description ''Rhinogobius candidianus'' can grow to standard length. The body is elongated, compressed posteriorly. The dead is depressed with an obtuse snout tip. The pelvic fins are united to a rounded sucking disc. Body coloration is yellow or dark brownish. There can be 6–7 indistinct blotches on side; some adults have blue spots. Distribution and population structure ''Rhinogobius candidianus'' is widely distributed in Taiwan. However, genetic data indicate that populations in the east and south of the island are likely resulting from introductions. Furthermore, genetic data show high population differentiation among the native populations, suggesting that this species has limited ability to disperse from one ...

Charles Tate Regan
Charles Tate Regan FRS (1 February 1878 – 12 January 1943) was a British ichthyologist, working mainly around the beginning of the 20th century. He did extensive work on fish classification schemes. Born in Sherborne, Dorset, he was educated at Derby School and Queens' College, Cambridge and in 1901 joined the staff of the Natural History Museum, where he became Keeper of Zoology, and later director of the entire museum, in which role he served from 1927 to 1938. Regan was elected Fellow of the Royal Society in 1917. Regan mentored a number of scientists, among them Ethelwynn Trewavas, who continued his work at the British Natural History Museum. Species Among the species he described is the Siamese fighting fish (''Betta splendens''). In turn, a number of fish species have been named ''regani'' in his honour: *A Thorny Catfish '' Anadoras regani'' (Steindachner, 1908) *The Dwarf Cichlid '' Apistogramma regani'' *'' Apogon regani'' *A Catfish '' Astroblepus regani'' * ...

Fish Measurement
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. Simply put, this measurement excludes the length of the caudal (tail) fin. * Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes (lampreys), and (usually) Elasmobranchii (sharks and rays), as well as some other fishes. Total length meas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of Taiwan
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freshwater Fish Of Taiwan
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh water is ...

Cyprinid Fish Of Asia
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family. It includes the carps, the true minnows, and relatives like the barbs and barbels. Cyprinidae is the largest and most diverse fish family and the largest vertebrate animal family in general with about 3,000 species, of which only 1,270 remain extant, divided into about 370 genera. Cyprinids range from about 12 mm in size to the giant barb (''Catlocarpio siamensis''). By genus and species count, the family makes up more than two-thirds of the ostariophysian order Cypriniformes. The family name is derived from the Greek word ( 'carp'). Biology and ecology Cyprinids are stomachless fish with toothless jaws. Even so, food can be effectively chewed by the gill rakers of the specialized last gill bow. These pharyngeal teeth allow the fish to make chewing motions against a chewing plate formed by a bony process of the skull. The pharyngeal teeth are unique to each species and are used by scie ...

Rhinogobius
''Rhinogobius'' is a genus of primarily freshwater goby, gobies native to tropical and temperate parts of eastern Asia. Most are small, streamlined in shape, and often sexually dimorphic. Few are of commercial importance, but ''R. duospilus'' is fairly widely traded as an fishkeeping, aquarium fish. Species There are currently 66 recognized species in this genus: * ''Rhinogobius albimaculatus'' Chen I-Shiung, I. S. Chen, Maurice Kottelat, Kottelat & Peter J. Miller, P. J.

Tamsui River
The Tamsui River (alternatively Danshui River, ) is third longest river in Taiwan after Zhuoshui River and Gaoping River, with a total length of , flowing through Hsinchu County, Taoyuan, Taipei and New Taipei City. It is located in northern part of the island. Geography The Tamsui River begins at the confluence of Xindian River and Dahan River at the western boundary of Taipei and New Taipei City, just north of Banqiao District, and flows northward and northwestward, passing the eponymous Tamsui District, then emptying into the Taiwan Strait. Formerly known as the "Dolatok River", it is one of the few rivers in the island that flows along a north–south direction. The river's three tributaries are the Xindian River, Dahan River and Keelung River. The Dahan River is the main tributary and has its headwaters in the Pintian Mountain in Hsinchu County and flows through Hsinchu County, Taoyuan City and New Taipei City. As a river system including the Dahan River, the Tamsui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lotic
River ecosystems are flowing waters that drain the landscape, and include the Biotic component, biotic (living) interactions amongst plants, animals and micro-organisms, as well as abiotic (nonliving) physical and chemical interactions of its many parts.Angelier, E. 2003. Ecology of Streams and Rivers. Science Publishers, Inc., Enfield. Pp. 215.”Biology Concepts & Connections Sixth Edition”, Campbell, Neil A. (2009), page 2, 3 and G-9. Retrieved 2010-06-14. River Ecosystem, ecosystems are part of larger Drainage basin, watershed networks or catchments, where smaller headwater streams drain into mid-size streams, which progressively drain into larger river networks. The major zones in river ecosystems are determined by the river bed's gradient or by the velocity of the current. Faster moving turbulent water typically contains greater concentrations of Oxygen saturation, dissolved oxygen, which supports greater biodiversity than the slow-moving water of pools.

Pelvic Fin
Pelvic fins or ventral fins are paired fins located on the ventral surface of fish. The paired pelvic fins are homologous to the hindlimbs of tetrapods. Structure and function Structure In actinopterygians, the pelvic fin consists of two endochondrally-derived bony girdles attached to bony radials. Dermal fin rays (lepidotrichia) are positioned distally from the radials. There are three pairs of muscles each on the dorsal and ventral side of the pelvic fin girdle that abduct and adduct the fin from the body. Pelvic fin structures can be extremely specialized in actinopterygians. Gobiids and lumpsuckers modify their pelvic fins into a sucker disk that allow them to adhere to the substrate or climb structures, such as waterfalls. In priapiumfish, males have modified their pelvic structures into a spiny copulatory device that grasps the female during mating.

Sun Moon Lake
Sun Moon Lake (; Thao: ''Zintun'') is a lake in Yuchi Township, Nantou County, Taiwan. It is the largest body of water in Taiwan. The area around the lake is home to the Thao tribe, one of aboriginal tribes of Taiwan. Sun Moon Lake surrounds a tiny island called Lalu. The east side of the lake resembles a sun while the west side resembles a moon, hence the name. Sun Moon Lake is located above sea level. It is deep and has a surface area of approximately . The area surrounding the lake has many trails for hiking. While swimming in Sun Moon Lake is usually not permitted, there is an annual 3-km race called the ''Swimming Carnival of Sun Moon Lake'' held around the Mid-Autumn Festival each year. The Sun Moon Lake Swimming Carnival was launched in 1983 and is listed among the Top 50 Open Water Swims in Asia and the Top 100 Open Water Swims of the World.

Type Locality (biology)
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 a ...
