Aenigmachanna
''Aenigmachanna'' is a genus of ray-finned fish in the order Ananbantiformes. It is the only genus in the family Aenigmachannidae, or dragon snakeheads. It contains two species, both of which are largely restricted to subterranean habitats in southwestern India, namely in the Western Ghats foothills in the state of Kerala. Both of the species in this genus display a unique array of traits that distinguish them from their closest living relatives, the true snakeheads in the family Channidae. These include a much longer and more slender body, numerous scales, a very long anal fin, and a lack of ability to maintain buoyancy. Molecular analyses indicate that they split off from Channidae around 34 or 109 MYA. This may indicate that Aenigmachannidae is a uniquely Gondwanan lineage, and if the higher end of estimations is correct, it may have survived the breakup of the Gondwanan supercontinent around 120 MYA. They are unique among cavefish for being one of the few cave-dwelling m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aenigmachanna Gollum
''Aenigmachanna gollum'', the Gollum snakehead, is a species of aquifer-dwelling Aenigmachanna, dragon snakehead fish that is Endemism, endemic to the Indian state of Kerala. Description ''A. gollum'' has an elongated, eel-like body coloured mostly brown and beige. Its fins are long and Transparency and translucency, transparent, with the dorsal fin stretching for about three-quarters of its body length, and the anal fin stretching for more than half its body length. Its pectoral fin is large, while the pelvic fin is absent. Its tailfin is ovoid. Several large scales cover the top of the head. It has a reduced swim bladder. Unlike many stygofauna – which usually have reduced colouring and have poor or no vision – ''A. gollum'' has well-developed pigmentation and normally-sized eyes. Due to its reduced swim bladder, ''A. gollum'' cannot remain buoyant in water. Like other snakehead fishes, it breathes air. It moves by undulating its fins, like an eel. Distribution and ha ...

Aenigmachanna Mahabali
''Aenigmachanna mahabali'', the Mahabali snakehead, is a species of troglophilic snakehead fish that is endemic to the Indian state of Kerala.The fish is named after Mahabali, an asura king from Hindu mythology who lived underground and is associated with Onam. It is known from a single specimen recovered from a well over 200 kilometers south of the locality where its closest relative, '' A. gollum'', was found. Alongside ''A. gollum'', it is unique for being the only known cave-dwelling snakehead fish. It can be distinguished from ''A. gollum'' due to having fewer dorsal fin rays, vertebrae, and lateral scales, as well as its pectoral fin rays extending beyond the margin of the membrane, forming filaments.

Cavefish
Cavefish or cave fish is a generic term for fresh and brackish water fish adapted to life in caves and other underground habitats. Related terms are subterranean fish, Troglomorphism, troglomorphic fish, troglobitic fish, stygobitic fish, phreatic fish, and hypogean fish.Romero, Aldemaro, editor (2001).

Anabantiformes
The Anabantiformes , is an Order (biology), order of bony fish (Teleostei) proposed in 2009. They are collectively known as labyrinth fish, are an Order (biology), order of air-breathing freshwater Actinopterygii, ray-finned fish with three suborders, eight Family (biology), families, and at least 350 species. This order is the sister group to the Synbranchiformes, with both comprising the Monophyly, monophyletic clade Anabantaria. Anabantaria is a sister group to the Carangiformes, with the clade comprising both being a sister clade to the Ovalentaria. This group of fish are found in Asia and Africa, with some species introduced to North America. These fish are characterized by the presence of teeth on the parasphenoid. The Snakehead (fish), snakeheads and the Anabantoidei, anabantoids are united by the presence of the labyrinth organ, which is a highly folded supraBranchial arches, branchial accessory breathing organ. It is formed by Blood vessel, vascularized expansion of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snakehead (fish)
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 .

Endemic Fauna Of The Western Ghats
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

Freshwater Fish Of India
Fishing in India is a major sector within the economy of India contributing 1.07% of its total Gross domestic product, GDP. The fishing sector in India supports the livelihood of over 28 million people in the country, especially within the marginalized and vulnerable communities. India is the third largest fish producing country in the world accounting for 7.96% of the global production and second largest producer of fish through aquaculture, after China. The total fish production during the 2020-21 is estimated at 14.73 million metric tonnes. According to the National Fisheries Development Board the Fisheries Industry generates an export earnings of Rs 334.41 billion. Centrally sponsored schemes will increase exports by Rs 1 lakh crore in FY25. 65,000 fishermen have been trained under these schemes from 2017 to 2020.

Fauna Of Kerala
Fauna (: faunae or faunas) is all of the animal life present in a particular region or time. The corresponding terms for plants and fungi are ''flora'' and ''funga'', respectively. Flora, fauna, funga and other forms of life are collectively referred to as '' biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Modern Greek equivalent of fauna (πανίς or rather πανίδα). ''Fauna'' is also the word for a book ...

Historical roles and occupations Poets and historians Rajasthani and Gujarati literature from the early and medieval period, upto the 19th century, has been mainly composed by Charans. The relationship between Charans and Rajputs is deeprooted in history. As Charans used to partake in battles alongside Rajputs, they were witnesses not only to battles but also to many other occasions and episodes forming part of the contemporary Rajput life. The poems composed about such wars and incidents had two qualities: basic histor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
