Sinobdella
''Sinobdella sinensis'' is an East Asian species of the spiny eel family of the order Synbranchiformes. It is the only species in the genus ''Sinobdella'' according to FishBase, but another species, '' S. dienbienensis'', is placed there by Catalog of Fishes (that species in ''Mastacembelus'' by FishBase). The placement of this genus has been debated. It is placed in Mastacembelidae as the sister group to the rest of the family. This species has been placed as a member of the family Chaudhuriidae, but the evidence for this relationship is not strong. This fish is a subtropical species found in rivers in China, Taiwan, and Vietnam Vietnam or Viet Nam ( vi, Việt Nam, ), officially the Socialist Republic of Vietnam,., group="n" is a country in Southeast Asia, at the eastern edge of mainland Southeast Asia, with an area of and population of 96 million, making i ....

Mastacembelus
''Mastacembelus'' is a genus of many species of spiny eel fish from the family Mastacembelidae. They are native to Africa (c. 45 species) and Asia (c. 15 species). Most are found in rivers and associated systems (even in rapids), but there are also species in other freshwater habitats and a particularly rich radiation is found in the Lake Tanganyika basin with 15 species (14 endemic). A few species can even occur in brackish water. Appearance The size and pattern varies greatly depending on the exact species of ''Mastacembelus''. The smallest are '' M. latens'' and '' M. simba'', which only reach a maximum total length of . At up to , the largest of both the family and this genus is '' M. erythrotaenia''. ''M. erythrotaenia'', often known as the fire eel, is blackish with an orange-red pattern, and it is a popular aquarium fish. Otherwise species in this genus are typically brownish and often have a spotted, speckled or mottled pattern, either in another brown hue, grayish or y ...

Mastacembelidae
The Mastacembelidae are a family of fishes, known as the spiny eels. The Mastacembelids are part of the Order Synbranchiformes, the swamp eels, which are part of the Actinopterygii (ray-finned fishes). In an evaluation of the family in 2004, the subfamilies of Mastacembelidae were found to not be well supported and were rejected. Also, the genera ''Caecomastacembelus'' and ''Aethiomastacembelus'' were placed in synonymy with ''Mastacembelus''. These fish originate from Africa, and southern and eastern Asia. Spiny eels generally inhabit soft-bottomed habitats in fresh and occasionally brackish water. Some species burrow in the substrate during the day or for certain months and have been found buried in soil in drying periods. These fish have an eel-like body. The largest species can reach a maximum length of . Very characteristic of this group is the long nose appendage with two tubulated nostrils. Mastacembelids have a series of well-separated dorsal spines on their back, hence ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chaudhuriidae
Chaudhuriidae, is a family of small freshwater eel-like fish related to the swamp eels and spiny eels, commonly known as the earthworm eels. The known species are literally the size and shape of earthworms, thus the family name. While one species, ''Chaudhuria caudata'' was reported from the Inle Lake by Nelson Annandale in 1918, the others have been only recently reported (since the 1970s), all in the eastern Asia area, from India to Korea. Neither the dorsal nor anal fins have spines, and in ''Nagaichthys'' and ''Pillaia'' they have fused with the caudal fin Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as ...; in the other genera, the caudal is small but separate. Their bodies have no scales. The few specimens found to date have been no longer than 8 cm, and ''Nagaichthys ... [...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 ...

Monotypic Fish Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.' ...

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] |

Subtropics
The subtropical zones or subtropics are geographical and climate zones to the north and south of the tropics. Geographically part of the temperate zones of both hemispheres, they cover the middle latitudes from to approximately 35° north and south. The horse latitudes lie within this range. Subtropical climates are often characterized by hot summers and mild winters with infrequent frost. Most subtropical climates fall into two basic types: humid subtropical (Koppen climate Cfa), where rainfall is often concentrated in the warmest months, for example Southeast China and the Southeastern United States, and dry summer or Mediterranean climate (Koppen climate Csa/Csb), where seasonal rainfall is concentrated in the cooler months, such as the Mediterranean Basin or Southern California. Subtropical climates can also occur at high elevations within the tropics, such as in the southern end of the Mexican Plateau and in Da Lat of the Vietnamese Central Highlands. The six climate cl ...
