Bagarius Bagarius
''Bagarius bagarius'', also known as the devil catfish, dwarf goonch or goonch ( bn, বাঘাইর), is a species of catfish in the genus ''Bagarius''. It is generally reported as being found in large and medium rivers in South Asia, and is likely synonymous with '' B. yarrelli''. Taxonomy Prior to 2021, the standard was to recognize two species of ''Bagarius'' from the Indian Subcontinent: First ''B. bagarius'', supposedly a small species (up to ) first described in 1822 by Francis Buchanan-Hamilton based on a specimen from the Ganges River. The second is '' B. yarrelli'', supposedly a very large species (up to ) first described in 1839 by William Henry Sykes based on a specimen from the Mula-Mutha River. Recent studies have not been able to document that more than one species exists in the Indian subcontinent, which, if confirmed, would mean that the name ''B. bagarius'' is a senior synonym of ''B. yarrelli'', which was confirmed by a 2021 study. In contrast, Southeast Asia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The IUCN Red List Of Threatened Species
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 provide sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mekong
The Mekong or Mekong River is a trans-boundary river in East Asia and Southeast Asia. It is the world's List of rivers by length, twelfth longest river and List of longest rivers of Asia, 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 language, Tai shortened to ''Mae Khong''. In Thai and Lao, ''Mae Nam'' ("Mother of Water[s]") 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Of Bhutan
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and 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 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 external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most fis ...

Sisoridae
Sisoridae is a family of catfishes. These Asian catfishes live in fast-moving waters and often have adaptations that allow them to adhere to objects in their habitats. The family includes about 235 species. Taxonomy The family Sisoridae is recognized as a natural, monophyletic group based on morphological and molecular evidence. It is divided into two subfamilies, Sisorinae and Glyptosterninae (glyptosternoids). The Sisorinae contain the five genera ''Bagarius'', ''Gagata'', '' Gogangra'', '' Nangra'', and ''Sisor''. The Glyptosterninae contain three tribes. Glyptothoracini contains only the genus ''Glyptothorax'' and Pseudecheneidina contains only the genus ''Pseudecheneis''. The remaining genera, '' Chimarrichthys'', '' Exostoma'', '' Glaridoglanis'', ''Glyptosternon'', ''Myersglanis'', '' Oreoglanis'', '' Parachiloglanis'', '' Pareuchiloglanis'', and '' Pseudexostoma'', are contained in the tribe Glyptosternina.

Shrimp
Shrimp are crustaceans (a form of shellfish) with elongated bodies and a primarily swimming mode of locomotion – most commonly Caridea and Dendrobranchiata of the decapod order, although some crustaceans outside of this order are referred to as "shrimp". More narrow definitions may be restricted to Caridea, to smaller species of either group or to only the marine species. Under a broader definition, ''shrimp'' may be synonymous with prawn, covering stalk-eyed swimming crustaceans with long, narrow muscular tails (abdomens), long whiskers ( antennae), and slender legs. Any small crustacean which resembles a shrimp tends to be called one. They swim forward by paddling with swimmerets on the underside of their abdomens, although their escape response is typically repeated flicks with the tail driving them backwards very quickly. Crabs and lobsters have strong walking legs, whereas shrimp have thin, fragile legs which they use primarily for perching.Rudloe & Rudloe (2009 ...

Chironomidae
The Chironomidae (informally known as chironomids, nonbiting midges, or lake flies) comprise a family of nematoceran flies with a global distribution. They are closely related to the Ceratopogonidae, Simuliidae, and Thaumaleidae. Many species superficially resemble mosquitoes, but they lack the wing scales and elongated mouthparts of the Culicidae. The name Chironomidae stems from the Ancient Greek word ''kheironómos'', "a pantomimist". Common names and biodiversity This is a large taxon of insects; some estimates of the species numbers suggest well over 10,000 world-wide. Males are easily recognized by their plumose antennae. Adults are known by a variety of vague and inconsistent common names, largely by confusion with other insects. For example, chironomids are known as "lake flies" in parts of Canada and Lake Winnebago, Wisconsin, but "bay flies" in the areas near the bay of Green Bay, Wisconsin. They are called "sand flies", "muckleheads", "muffleheads", "Canadian so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mahakali River
The Sharda River, also called Kali River and Mahakali River, originates at Kalapani in the Himalayas at an elevation of in the Pithoragarh district in Uttarakhand, India. It flows along Nepal's western border with India and has a basin area of . It joins Ghaghra River, a tributary of the Ganges. It takes the name Kali River from the union of the two streams at Gunji as it flows through the hills. After Brahmadev Mandi near Tanakpur, it enters the Terai plains, where it is called Sharda River. It offers potential for hydroelectric power generation. The river is also proposed as source for one of the many projects in the Himalayan component of the Indian Rivers Inter-link project. Etymology and naming It is named after Śāradā, which is another name for Saraswati, the goddess of learning.

Kali River Goonch Attacks
The Kali River goonch attacks were a series of fatal attacks on humans believed to be perpetrated by a goonch weighing in three villages on the banks of the Kali River in India and Nepal, between 1998 and 2007. This is the subject of a TV documentary aired on 22 October 2008, as well as an episode about the Kali River goonch attacks on the Animal Planet series ''River Monsters''. Attacks The first attack occurred in April 1998, when at 13:00, 17-year-old Dil Bahadur, while swimming in the river, was dragged underwater in front of his girlfriend and several eyewitnesses. No remains were found, even after a three-day search spanning 5 kilometers (3.11 miles). Three months later, at Dharma Ghat, a young boy was pulled underwater in front of his father, who watched helplessly. No corpse was ever found. The final attack occurred in 2007 when an 18-year-old Nepalese man disappeared in the river, dragged down by something described as a mud-colored "water pig". Investigation Briti ...
