Channa Diplogramma
The Malabar snakehead (''Channa diplogramma'') is a vulnerable species of snakehead from fresh water in the Western Ghats in India. Until 2011, its scientific name was usually considered to be a synonym of '' C. micropeltes'', the giant snakehead.Benziger A, Philip S, Raghavan R, Anvar Ali PH, Sukumaran M, et al. (2011Unraveling a 146 Years Old Taxonomic Puzzle: Validation of Malabar Snakehead, Species-Status and Its Relevance for Channid Systematics and Evolution.''PLoS ONE 6(6): e21272. doi:10.1371/journal.pone.0021272'' Taxonomy Sir Francis Day described ''Ophiocephalus diplogramma'' in 1865 based on one juvenile specimen (42 mm in length) collected near the mouth of the Cochin River in the port city of Cochin (southwestern India), and called it Malabar snakehead. The color pattern of this juvenile matched with that of juveniles of another species of snakehead, '' O. micropeltes'', originally described by Cuvier and Valenciennes from Java, Indonesia.

Francis Day
Francis Talbot Day (2 March 1829 – 10 July 1889) was an army surgeon and naturalist in the Madras Presidency who later became the Inspector-General of Fisheries in India and Burma. A pioneer ichthyologist, he described more than three hundred fishes in the two-volume work on ''The Fishes of India''. He also wrote the fish volumes of the Fauna of British India series. He was also responsible for the introduction of trout into the Nilgiri hills, for which he received a medal from the French Societe d'Acclimatation. Many of his fish specimens are distributed across museums with only a small fraction deposited in the British Museum (Natural History Museum, London), an anomaly caused by a prolonged conflict with Albert Günther, the keeper of zoology there. Biography Day was born in Maresfield, East Sussex, the third son of William and Ann Elliott née Le Blanc. The family estate included two thousand acres with forty tenant farmers during his childhood. William Day was inter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Forest Snakehead
The forest snakehead (''Channa lucius'') is a species of snakehead, a fish of the family Channidae. Its range includes most of Southeast Asia and parts of southern China. It lives in forest streams and can reach in length. The forest snakehead is known in Thai language as ''pla krasong'' ( th, ปลากระสง ). Khmer language called it កញ្ជនជៃ (''kanh chon chey''), Indonesians named it ''kehung'', while in Malaysia, they called it ''ikan bujuk'' in Malay Language A genetic study published in 2017 indicates that ''C. lucius'' is a species complex.Conte-Grand, C., Britz, R., Dahanukar, N., Raghavan, R., Pethi-yagoda, R., Tan, H.H., Hadiaty, R.K., Yaakob, N.S. & Rüber, L.

Channa Bankanensis
''Channa'' is a genus of predatory fish in the family Channidae, commonly known as snakeheads, native to freshwater habitats in Asia. This genus contains about 50 scientifically described species. The genus has a wide natural distribution extending from Iraq in the west, to Indonesia and China in the east, and parts of Siberia in the Far East. A particularly high richness of species exists in Myanmar (Burma) and northeastern India, and many ''Channa'' species live nowhere else. In contrast, a few widespread species have been introduced to several regions outside their natural range, where they often become invasive. The large and medium-sized ''Channa'' species are among the most common staple food fish in several Asian countries, and they are extensively cultured.Kumar, K., R. Kumar, S. Saurabh, M. Sahoo, A.K.

Lateral Line
The lateral line, also called the lateral line organ (LLO), is a system of sensory organs found in fish, used to detect movement, vibration, and pressure gradients in the surrounding water. The sensory ability is achieved via modified epithelial cells, known as hair cells, which respond to displacement caused by motion and transduce these signals into electrical impulses via excitatory synapses. Lateral lines serve an important role in schooling behavior, predation, and orientation. Fish can use their lateral line system to follow the vortices produced by fleeing prey. Lateral lines are usually visible as faint lines of pores running lengthwise down each side, from the vicinity of the gill covers to the base of the tail. In some species, the receptive organs of the lateral line have been modified to function as electroreceptors, which are organs used to detect electrical impulses, and as such, these systems remain closely linked. Most amphibian larvae and some fully aquatic adult ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
