Triplophysa Marmorata
''Triplophysa marmorata'', the Kashmir Triplophysa-loach, is a species of ray-finned fish found in Asia.Bashir, A., Bisht, B.S., Mir, J.I., Kumar, R. & Patiyal, R.S. (2016): Morphological, molecular characterization and taxonomic status of ''Triplophysa marmorata'' and ''Triplophysa kashmirensis'' (Cypriniformes: Nemacheilidae) from Kashmir valley, India. ''Revista de Biología Tropical, 64 (2): 473-482.'' It's a scaleless inland fish that is endemic of wetlands like the Wular Lake in Jammu and Kashmir (union territory), Jammu and Kashmir, India. Like similar species ''T. kashmirensis'', it presents a slender caudal peduncle, but it's shorter in the case of ''T. marmorata''. Its specimens can also be differentiated because of their shorter lateral line length. Their diet is composed of detritus, plants (including algae) that coat rocks and stones, and the associated invertebrate fauna. They reach maturity after two years.

Johann Jakob Heckel
Johann Jakob Heckel (23 January 1790 – 1 March 1857) was an Austrian taxidermist, zoologist, and ichthyologist from Mannheim in the Electoral Palatinate. Life Though not a formally trained biologist, he worked his way up through the ranks to eventually become the director of the Fish Collection at the Naturhistorisches Museum in Vienna. For the most part, he was not a traveler or explorer like many of the scientists of the time, he remained in Vienna, where he studied and catalogued specimens sent to him from the field. Among those who brought specimens to him were Karl Alexander Hügel, Joseph Russegger and Theodor Kotschy — involving collection activities in Kashmir, the Middle East and northeastern Africa that greatly enriched the Vienna museum. Fish were his specialty and he worked with many of the greatest ichthyologists of his time including Cuvier, Valenciennes, Bonaparte, Müller, and Troschel.

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from ''Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Actinoptery ...

Asia
Asia (, ) is one of the world's most notable geographical regions, which is either considered a continent in its own right or a subcontinent of Eurasia, which shares the continental landmass of Afro-Eurasia with Africa. Asia covers an area of , about 30% of Earth's total land area and 8.7% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Its 4.7 billion people constitute roughly 60% of the world's population. In general terms, Asia is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a historical and cultural construct, as there is no clear physical and geographical separation between them. It is somewhat arbitrary and has moved since its first conception in classical antiquity. The division of Eurasia into two continents reflects East–West cultural, linguistic, ...

Wular Lake
Wular Lake (), also known as Wolar () in Kashmiri, is one of the largest fresh water lakes in South Asia. It is located near Bandipora town in Bandipora district of Jammu and Kashmir, India. The lake basin was formed as a result of tectonic activity and is fed by the Jhelum River and stream madhumati. The lake's size varies seasonally from 30 to 189 square kilometres. In addition, much of the lake has been drained as a result of willow plantations being built on the shore in the 1950s. Etymology In ancient times, Wular Lake was also called Mahapadmasar (Sanskrit: महापद्मसरः). Nilamata Purana also mentions it as ''Mahapadmasaras''. The lake, with its big dimensions and the extent of water, gives rise to high leaping waves in the afternoons, called Ullola in Sanskrit, meaning "stormy leaping, high rising waves". Therefore, it was also being called ''Ullola''. It is believed to have gotten corrupted over the centuries to ''Wulor'' or ''Wular''.

Jammu And Kashmir (union Territory)
Jammu and Kashmir is a region administered by India as a union territory and consists of the southern portion of the larger Kashmir region, which has been the subject of a dispute between India and Pakistan since 1947, and between India and China since 1962.(a) (subscription required) Quote: "Kashmir, region of the northwestern Indian subcontinent ... has been the subject of dispute between India and Pakistan since the partition of the Indian subcontinent in 1947. The northern and western portions are administered by Pakistan and comprise three areas: Azad Kashmir, Gilgit, and Baltistan, the last two being part of a territory called the Northern Areas. Administered by India are the southern and southeastern portions, which constitute the state of Jammu and Kashmir but are slated to be split into two union territories. China became active in the eastern area of Kashmir in the 1950s and has controlled the northeastern part of Ladakh (the easternmost portion of the region) sinc ...

Fish Of Asia
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 ...
