Epalzeorhynchos Bicolor
The red-tailed black shark (''Epalzeorhynchos bicolor''; syn. ''Labeo bicolor''), also known as the redtail shark and redtail sharkminnow, is a species of freshwater fish in the carp family, Cyprinidae. Despite its name, it is more closely related to carp. It is Endemism, endemic to Thailand and currently critically endangered, but common in aquaria, where it is prized for its deep black body and vivid red or vivid orange tail. The red-tailed black sharks seen in the aquarium trade today are all captive bred. Distribution The species is Endemism, endemic to Thailand, and was described by Hugh M. Smith in 1931 as being 'not uncommon in Bueng Boraphet and the streams which lead from it, and as being found in the Chao Phraya River as far south as Bangkok. A 1934 expedition reported catching a specimen in the Silom canal. As of 2011 it is only known at a single location in the Chao Phraya basin and has Critically Endangered status on the IUCN Red List. From 1996 until 2011 it was be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hugh McCormick Smith
Hugh McCormick Smith, also H. M. Smith (November 21, 1865 – September 28, 1941) was an American ichthyologist and administrator in the United States Bureau of Fisheries. Biography Smith was born in Washington, D.C. In 1888, he received a Doctor of Medicine from Georgetown University; then, in 1908, a Doctor of Law from the Dickinson School of Law at Dickinson College. He began working for the United States Fish Commission (formally, the United States Commission on Fish and Fisheries) in 1886 as an assistant. He directed the scientific research center there from 1897 to 1903. From 1901 to 1902, he directed the Marine Biological Laboratory at Woods Hole, Massachusetts. At the same time, he was on the faculty at Georgetown, teaching medicine from 1888 to 1902 and histology from 1895 to 1902. From 1907 to 1910, Smith led the scientific party aboard the U.S. Bureau of Fisheries (successor organization of the U.S. Fish Commission) research ship during her two-and-a-half-year expedit ...

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of Thailand
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] |
Fish Of Thailand
Fish are Aquatic animal, aquatic, craniate, gill-bearing animals that lack Limb (anatomy), limbs with Digit (anatomy), digits. Included in this definition are the living hagfish, lampreys, and Chondrichthyes, cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a vertebrate, true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed placodermi, external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epalzeorhynchos
''Epalzeorhynchos'' is a small ray-finned fish genus of the family Cyprinidae. Its members are – like some other cyprinids – known as "freshwater sharks" or simply "sharks". They are, however, freshwater members of the Osteichthyes lineage which is distinct from the Chondrichthyes lineage of sharks. The description of these animals as "shark" is most likely a reference to the shark-like shape of these popular cyprinids. The genus ''Epalzeorhynchos'' may be placed in the tribe Garrini of the Labeoninae, or in subtribe Garraina of tribe Labeonini, if these are considered a tribe of subfamily Cyprininae. It is not yet resolved which is a more appropriate representation of their phylogeny. Description and ecology In size and shape ''Epalzeorhynchos'' generally resemble the Indian loaches (''Botia''), which, although they are also cypriniforms, are far too distantly related to have anything other than convergent evolution be responsible for this similarity.

Chromobotia Macracanthus
The clown loach (''Chromobotia macracanthus''), or tiger botia, is a tropical freshwater fish belonging to the botiid loach family. It is the monotypic, sole member of the genus ''Chromobotia''. It originates in inland waters in Indonesia on the islands of Sumatra and Borneo. In Sentarum, West Borneo that fish named: ulanguli. It is a popular fish in the freshwater aquarium trade and is sold worldwide. Taxonomy and naming The fish was first described as ''Cobitis macracanthus'' by Pieter Bleeker in 1852. In 1989, its scientific name was changed to ''Botia macracanthus''. In 2004, Maurice Kottelat, Dr. Maurice Kottelat divided the genus ''Botia'', containing 47 different species, into seven separate genus, genera, resulting in the clown loach being placed in a genus of its own, ''Chromobotia''. Its scientific name roughly translates to “Large-thorned colourful warrior”. The common name, "clown loach" comes from the fish's bright colours and stripes (often tropical fish with s ...

Metynnis Argenteus
''Metynnis argenteus'' is a species of serrasalmid fish endemic to the Tapajós River Basin in Brazil. It is one of the species known in the aquarium trade as the " silver dollar". ''M. argenteus'' is generally considered the archetypal silver dollar, although it and the very similar '' M. hypsauchen'' frequently have been confused.SeriouslyFish: Metynnis argenteus.' Retrieved 4 June 2014 Identification Round-bodied and laterally compressed, under normal conditions ''M. argenteus'' is a uniform silver colour, sometimes showing vague red colouration in the fins and around the throat. Commonly seen for sale as juveniles at around two inches long, they are peaceful shoalers. Fully grown females in captivity can reach a length of between five and six inches while males tend to be marginally smaller. In good condition, females tend to be fuller in the belly than males, while males develop marginally longer fins as they grow older. During courtship and breeding, males develop two lar ...

Hard Water
Hard water is water that has high mineral content (in contrast with "soft water"). Hard water is formed when water percolates through deposits of limestone, chalk or gypsum, which are largely made up of calcium and magnesium carbonates, bicarbonates and sulfates. Hard drinking water may have moderate health benefits. It can pose critical problems in industrial settings, where water hardness is monitored to avoid costly breakdowns in boilers, cooling towers, and other equipment that handles water. In domestic settings, hard water is often indicated by a lack of foam formation when soap is agitated in water, and by the formation of limescale in kettles and water heaters.World Health OrganizatioHardness in Drinking-Water 2003 Wherever water hardness is a concern, water softening is commonly used to reduce hard water's adverse effects. Origins Natural rainwater, snow and other forms of precipitation typically have low concentrations of multivalent cations such as calcium and magnes ...

Extinct In The Wild
A species that is extinct in the wild (EW) is one that has been categorized by the International Union for Conservation of Nature as known only by living members kept in captivity or as a naturalized population outside its historic range due to massive habitat loss. Examples Examples of species and subspecies that are extinct in the wild include: *Alagoas curassow (last unconfirmed sighting reported in the late 1980s, listed extinct in the wild since 1994) *Beloribitsa * Cachorrito de charco palmal (last seen in 1994, listed extinct in the wild since 1996) * Christmas Island blue-tailed skink (listed extinct in the wild since 2014) *Dabry's sturgeon (listed extinct in the wild since 2022) * Escarpment cycad (listed extinct in the wild since 2006) *Franklinia (last seen in 1803, listed extinct in the wild since 1998) *Golden skiffia (listed extinct in the wild since 1996) *Guam kingfisher (listed extinct in the wild since 1986) *Hawaiian crow or ʻalalā (last seen in 2002, li ...

Silom
Si Lom Road (also written as Silom, th, สีลม, ) is a major street in the Thai capital Bangkok, best known for its commercial neighbourhood, which, along with the nearby and roughly parallel Sathon Road, forms one of the city's main business districts. It runs in a southwest–northeast direction between Charoen Krung and Rama IV roads in the city's Bang Rak District, forming the boundary between Suriyawong Subdistrict to its north and Si Lom Subdistrict to its south. Si Lom was one of the earliest modern roads to be built in the city, and some of its side streets serve historic ethnic neighbourhoods from the late nineteenth century, while others are known as shopping and nightlife venues. History In the reign of King Mongkut (Rama IV, 1851–1868), Siam (as Thailand was then known) began modernizing and opening up to the West. Major roads were first built in Bangkok, with Thanon Trong (what is now Rama IV Road) built together with a canal in 1857, followed by Charo ...

Freshwater Fish
Freshwater fish are those that spend some or all of their lives in fresh water, such as rivers and lakes, with a salinity of less than 1.05%. These environments differ from marine conditions in many ways, especially the difference in levels of salinity. To survive fresh water, the fish need a range of physiology, physiological adaptations. 41.24% of all known species of fish are found in fresh water. This is primarily due to the rapid speciation that the scattered habitats make possible. When dealing with ponds and lakes, one might use the same basic models of speciation as when studying island biogeography. Physiology Freshwater fish differ physiologically from salt water fish in several respects. Their gills must be able to diffuse dissolved gases while keeping the salts in the body fluids inside. Their scales reduce water diffusion through the skin: freshwater fish that have lost too many scales will die. They also have well developed kidneys to reclaim salts from body flui ...

Bangkok
Bangkok, officially known in Thai language, Thai as Krung Thep Maha Nakhon and colloquially as Krung Thep, is the capital and most populous city of Thailand. The city occupies in the Chao Phraya River delta in central Thailand and has an estimated population of 10.539 million as of 2020, 15.3 percent of the country's population. Over 14 million people (22.2 percent) lived within the surrounding Bangkok Metropolitan Region at the 2010 census, making Bangkok an extreme primate city, dwarfing Thailand's other urban centres in both size and importance to the national economy. Bangkok traces its roots to a small trading post during the Ayutthaya Kingdom in the 15th century, which eventually grew and became the site of two capital cities, Thonburi Kingdom, Thonburi in 1768 and Rattanakosin Kingdom (1782–1932), Rattanakosin in 1782. Bangkok was at the heart of the modernization of Siam, later renamed Thailand, during the late-19th century, as the country faced pressures from the ...
