Channa Amphibeus
The Borna snakehead, or Chel snakehead,Courtenay, Jr., Walter R. and James D. Williams ''USGS Circular 1251: Snakeheads (Pisces, Chinnidae) - A Biological Synopsis and Risk Assessment''. U.S. Department of the Interior, U.S. Geological Survey. 2004-04-01. Retrieved 2007-07-16. ''Channa amphibeus'', is an extremely rare species of snakehead. ''C. amphibeus'' is native only to the Chel River (in the drainage of the Brahmaputra), of the Bhutan foothills, in northern Bengal, India. As with all snakeheads, ''C. amphibeus'' is an aggressive predator. The fish grows up to about 25 cm (10 inches). ''C. amphibeus'' requires warm fresh water (about 22–28˚C) to properly mature, and access to atmospheric oxygen.AC Tropical Fis''Chel Snakehead - Channa amphibeus''. 2004-6. Retrieved 2008-04-30 It was reported that during rainy periods, young are found “in flooded paddy-fields enclosed by forest; large fish can be found in pools of dried streams in forests.” This is a manifestati ...

John McClelland (doctor)
Sir John McClelland (1805–1883) was a British medical doctor with interests in geology and biology, who worked for the East India Company. In 1835 he was sent on a mission (Tea Committee) to identify if tea could be grown in north-eastern India along with Nathaniel Wallich and William Griffith. This mission ran into troubles with the members of the group. McClelland was appointed 1836 as the secretary of the "Coal Committee", the forerunner of the Geological Survey of India (GSI), formed to explore possibilities to exploit Indian coal. He was the first to propose hiring professional geologists for the task. He was also involved in surveys of forests and his reports led to the establishment of the Forest Department in India. He also served as an interim superintendent of the Calcutta Botanical Garden from 1846 to 1847 and was editor of the ''Calcutta Journal of Natural History'' from 1841–1847. Legacy McClelland is commemorated in the name of the mountain bulbul, ''Ixos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Channidae
The snakeheads are members of the freshwater perciform fish family Channidae, native to parts of Africa and Asia. These elongated, predatory fish are distinguished by their long dorsal fins, large mouths, and shiny teeth. They breathe air with gills, which allows them to migrate short distances over land. They have suprabranchial organs, which are primitive forms of labyrinth organs, that develop when they grow older. The two extant genera are ''Channa'' in Asia and ''Parachanna'' in Africa, consisting of more than 50 species. They are valuable as a food source and have become notorious as an intentionally released invasive species. These fish have been kept as pets but as they get larger, people let them go into ponds, lakes, and rivers, making these fish invasive. Description The various species of snakeheads differ greatly in size; dwarf snakeheads, such as ''Channa orientalis'', do not surpass in length. Most other snakeheads reach between . Five species ('' C. argus'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brahmaputra River
The Brahmaputra is a trans-boundary river which flows through Tibet, northeast India, and Bangladesh. It is also known as the Yarlung Tsangpo in Tibetan, the Siang/Dihang River in Arunachali, Luit in Assamese, and Jamuna River in Bangla. It is the 9th largest river in the world by discharge, and the 15th longest. With its origin in the Manasarovar Lake region, near Mount Kailash, on the northern side of the Himalayas in Burang County of Tibet where it is known as the Yarlung Tsangpo River, It flows along southern Tibet to break through the Himalayas in great gorges (including the Yarlung Tsangpo Grand Canyon) and into Arunachal Pradesh. It flows southwest through the Assam Valley as the Brahmaputra and south through Bangladesh as the Jamuna (not to be confused with the Yamuna of India). In the vast Ganges Delta, it merges with the Ganges, popularly known as the Padma in Bangladesh, and becomes the Meghna and ultimately empties into the Bay of Bengal. About long, the Bra ...

Bengal
Bengal ( ; bn, বাংলা/বঙ্গ, translit=Bānglā/Bôngô, ) is a geopolitical, cultural and historical region in South Asia, specifically in the eastern part of the Indian subcontinent at the apex of the Bay of Bengal, predominantly covering present-day Bangladesh and the Indian state of West Bengal. Geographically, it consists of the Ganges-Brahmaputra delta system, the largest river delta in the world and a section of the Himalayas up to Nepal and Bhutan. Dense woodlands, including hilly rainforests, cover Bengal's northern and eastern areas, while an elevated forested plateau covers its central area; the highest point is at Sandakphu. In the littoral southwest are the Sundarbans, the world's largest mangrove forest. The region has a monsoon climate, which the Bengali calendar divides into six seasons. Bengal, then known as Gangaridai, was a leading power in ancient South Asia, with extensive trade networks forming connections to as far away as Roman Egypt. ...

Labyrinth Organ
The Anabantoidei are a suborder of anabantiform ray-finned freshwater fish distinguished by their possession of a lung-like labyrinth organ, which enables them to breathe air. The fish in the Anabantoidei suborder are known as anabantoids or labyrinth fish, or colloquially as gouramies. Some labyrinth fish are important food fish, and many others, such as the Siamese fighting fish and paradise fish, are popular as aquarium fish. Labyrinth organ The labyrinth organ, a defining characteristic of fish in the suborder Anabantoidei, is a much-folded supra branchial accessory breathing organ. It is formed by vascularized expansion of the epibranchial bone of the first gill arch and used for respiration in air.Pinter, H. (1986). Labyrinth Fish. Barron's Educational Series, Inc., This organ allows labyrinth fish to take in oxygen directly from the air, instead of taking it from the water in which they reside through use of gills. The labyrinth organ helps the inhaled oxygen to be abs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rabha
The Rabha are a Tibeto-Burman community to the Indian states of Assam, Meghalaya and West Bengal. They primarily inhabit the plains of Lower Assam and the Dooars, while some are found in the Garo Hills. Most of the Rabhas of Dooars refer to themselves as Rabha, but some of them often declare themselves as Kocha. The Rabha community have a rich, multi-faceted and distinct culture of their own. The agricultural practices, food habit and belief systems of the Rabhas reflect a conglomeration of features from both the Indo-Aryan and Tibeto-Burmese culture. The Rabha society is patrilineal . The village economy is based on agriculture and both men and women work in the fields. The women wear colorful clothes that they weave themselves and wear a lot of beads and silver ornaments.
