Siluridae
Siluridae is the nominate family of catfishes in the order Siluriformes. About 105 living species of silurids are placed in 12 or 14 genera. Although silurids occur across much of Europe and Asia, they are most diverse in Southeast Asia, beyond which their diversity decreases in temperate East Asia, the Indian subcontinent, Southwest Asia, and Europe. Silurids are apparently absent from much of central Asia. The family can be divided into two groups, a temperate North Eurasian clade and a more diverse subtropical/tropical South and Southeast Asian clade. Notable species *Wels catfish, ''Silurus glanis'' *Phantom catfish, ''Kryptopterus vitreolus'' *''Wallago attu'' *Wallagonia leerii *Aristotle's catfish *Amur catfish *Phalacronotus apogon *Ompok Common Features The Family Siluridae is very diverse, with not very many distinctive features among all species, but some major ones include gigantism, and smaller versions of attributes that Catfish regularly have, such as smaller fi ...

Chao Phraya River
The Chao Phraya ( or ; th, แม่น้ำเจ้าพระยา, , or ) is the major river in Thailand, with its low alluvial plain forming the centre of the country. It flows through Bangkok and then into the Gulf of Thailand. Etymology On many old European maps, the river is named the ''Mae Nam'' (Thai: แม่น้ำ), the Thai word for "river" (literally, "motherly water"). James McCarthy, F.R.G.S., who served as Director-General of the Siamese Government Surveys prior to establishment of the Royal Survey Department, wrote in his account, "''Mae Nam'' is a generic term, ''mae'' signifying "mother" and ''Nam'' "water," and the epithet Chao P'ia signifies that it is the chief river in the kingdom of Siam." H. Warington Smyth, who served as Director of the Department of Mines in Siam from 1891 to 1896, refers to it in his book first published in 1898 as "the Mae Nam Chao Phraya". In the English-language media in Thailand, the name Chao Phraya River is oft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Belodon
''Belodon'' (meaning "arrow tooth") is a genus of phytosaur, a crocodile-like reptile that lived during the Triassic. Its fossils have been found in Europe and elsewhere. The type species, ''Belodon plieningeri'', was named by prolific German paleontologist Christian Erich Hermann von Meyer in 1844. Many other species were also named, among them ''Belodon buceros'' (named by Edward Drinker Cope in 1881),Cope, E.D. (1881). "''Belodon'' in New Mexico". ''American Naturalist'' 15: 922-923. ''Belodon kapfii'' (von Meyer, 1861), ''Belodon lepturus'' (Cope, 1870),Cope, E.D. (1870). "Reptilia of the Triassic Formation of the United States". ''American Naturalist'' 4: 562-563. ''Belodon priscus'' (originally described as ''Compsosaurus priscus'' by Joseph Leidy in 1856),Leidy, J. (1856). "Notice of some remains of extinct vertebrated animals".

Fish Migration
Fish migration is mass relocation by fish from one area or body of water to another. Many types of fish migrate on a regular basis, on time scales ranging from daily to annually or longer, and over distances ranging from a few metres to thousands of kilometres. Such migrations are usually done for better feeding or to reproduce, but in other cases the reasons are unclear. Fish migrations involve movements of schools of fish on a scale and duration larger than those arising during normal daily activities. Some particular types of migration are ''anadromous'', in which adult fish live in the sea and migrate into fresh water to spawn; and ''catadromous'', in which adult fish live in fresh water and migrate into salt water to spawn. Marine forage fish often make large migrations between their spawning, feeding and nursery grounds. Movements are associated with ocean currents and with the availability of food in different areas at different times of year. The migratory movements m ...

Explosive
An explosive (or explosive material) is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure. An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances. The potential energy stored in an explosive material may, for example, be * chemical energy, such as nitroglycerin or grain dust * pressurized gas, such as a gas cylinder, aerosol can, or BLEVE * nuclear energy, such as in the fissile isotopes uranium-235 and plutonium-239 Explosive materials may be categorized by the speed at which they expand. Materials that detonate (the front of the chemical reaction moves faster through the material than the speed of sound) are said to be "high explosives" and materials that deflagrate are said to be "low explosives". Explosives may al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mekong River
The Mekong or Mekong River is a trans-boundary river in East Asia and Southeast Asia. It is the world's twelfth longest river and the third longest in Asia. Its estimated length is , and it drains an area of , discharging of water annually. From the Tibetan Plateau the river runs through China, Myanmar, Laos, Thailand, Cambodia, and Vietnam. The extreme seasonal variations in flow and the presence of rapids and waterfalls in the Mekong make navigation difficult. Even so, the river is a major trade route between western China and Southeast Asia. Names The Mekong was originally called ''Mae Nam Khong'' from a contracted form of Tai shortened to ''Mae Khong''. In Thai and Lao, ''Mae Nam'' ("Mother of Water ) is used for large rivers and ''Khong'' is the proper name referred to as "River Khong". However, ''Khong'' is an archaic word meaning "river", loaned from Austroasiatic languages, such as Vietnamese ''sông'' (from *''krong'') and Mon ''kruŋ'' "river", which led to Chin ...

Zootaxa
''Zootaxa'' is a peer-reviewed scientific mega journal for animal taxonomists. It is published by Magnolia Press (Auckland, New Zealand). The journal was established by Zhi-Qiang Zhang in 2001 and new issues are published multiple times a week. From 2001 to 2020, more than 60,000 new species have been described in the journal accounting for around 25% of all new taxa indexed in The Zoological Record in the last few years. Print and online versions are available. Temporary suspension from JCR The journal exhibited high levels of self-citation and its journal impact factor of 2019 was suspended from ''Journal Citation Reports'' in 2020, a sanction which hit 34 journals in total. Biologist Ross Mounce noted that high levels of self-citation may be inevitable for a journal which publishes a large share of new species classification. Later that year this decision was reversed and it was admitted that levels of self-citation are appropriate considering the large proportion of papers f ...

Khone Falls
The Khone Falls and Pha Pheng Falls ( lo, ນ້ຳຕົກຕາດຄອນພະເພັງ; km, ល្បាក់ខោន, ''Lbak Khaon'') together form a waterfall located in Champasak Province on the Mekong River in southern Laos, near the border with Cambodia. At 10,783 metres (35,376 feet or 6.7 miles) in width from one edge of its multiple channels to the other, it is the widest waterfall in the world. The Khone Falls are the largest in southeast Asia, and are the main reason that the Mekong is not fully navigable into China. The falls are characterised by thousands of islands and countless waterways, giving the area its name Si Phan Don or 'the 4,000 islands'. The highest falls reach to ; the succession of rapids stretch of the river's length. The average discharge of the cataract is nearly , with the highest flow on record at over . __NoTOC__ Navigable efforts Because the Khone Falls stop the Mekong river from carrying boat traffic to and from China, in the l ...

Cyprinidae
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 scient ...
