Aenigmachanna Gollum Taxonomy
''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 dragon snakehead fish that is 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 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 habitat ''A. gollum'' is known only from its type locality, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, troglomorphic fish, troglobitic fish, stygobitic fish, phreatic fish and hypogean fish.Romero, Aldemaro, editor (2001). ''The Biology of Hypogean Fishes.'' Developments in Environmental Biology of Fishes. Helfman, G.S. (2007). ''Fish Conservation: A Guide to Understanding and Restoring Global Aquatic Biodiversity and Fishery Resources'', pp. 41–42. Island Press. There are more than 200 scientifically described species of obligate cavefish found on all continents, except Antarctica. Although widespread as a group, many cavefish species have very small ranges and are seriously threatened.Fenolio, D.B.; Zhao, Y.; Niemiller, M.L.; and Stout, J. (2013).

Endemic Fauna Of The Western Ghats
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Freshwater Fish Of India
Fishing in India is a major sector within the economy of India contributing 1.07% of its total 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. Freshwater fishing consists of 55% of total fish production. According to the Ministry of Fisheries, Animal Husbandry, Dairying, fish production increased from 7.52 lakh tonnes in ye ...

Fauna Of Kerala
Fauna is all of the animal life present in a particular region or time. The corresponding term for plants is ''flora'', and for fungi, it is ''funga''. 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 Greek equivalent of fauna. ''Fauna'' is also the word for a book that catalogues the animals in such a manner. The term was first used by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rahul G
Rahul is a popular male name in India and has a variety of meanings. The earliest meaning found in the Upanishads is "conqueror of all miseries." Later use of the word is attributed to the Buddha, who named his son '' Rahula'' as he felt that family ties could be an obstacle in the path to renunciation and nirvana. Buddha uttered Rahul when he first saw his son and gave a new meaning "relationship" and "bondage" to this name. Rahul means ''Moon, Able/efficient'' in Sanskrit and Pali. Rahul also means "Traveler" in Arabic.

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. References Fish described in 2019 mahabali Mahabali (IAST: Mahābalī), also known as Bali, Indrasenan, or Māveli, is a daitya king featured in Hinduism. He is the grandson of Prahlada, and a descendant of the sage Kashyapa. There are many versions of his legend, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Relict (biology)
In biogeography and paleontology, a relict is a population or taxon of organisms that was more widespread or more diverse in the past. A relictual population is a population currently inhabiting a restricted area whose range was far wider during a previous geologic epoch. Similarly, a relictual taxon is a taxon (e.g. species or other lineage) which is the sole surviving representative of a formerly diverse group. Definition A relict (or relic) plant or animal is a taxon that persists as a remnant of what was once a diverse and widespread population. Relictualism occurs when a widespread habitat or range changes and a small area becomes cut off from the whole. A subset of the population is then confined to the available hospitable area, and survives there while the broader population either shrinks or evolves divergently. This phenomenon differs from endemism in that the range of the population was not always restricted to the local region. In other words, the species or group did n ...
