Sunder Lal Hora
Sunder Lal Hora (22 May 1896 – 8 December 1955) was an Indian ichthyologist known for his biogeographic theory on the affinities of Western Ghats and Indomalayan fish forms. Life Hora was born at Hafizabad in the Punjab (modern day Pakistan) on 2 May 1896. He schooled in Jullunder before college at Lahore. He met Thomas Nelson Annandale who visited his college in Lahore in 1919 and was invited to the Zoological Survey of India. In 1921 he became in-charge of ichthyology and herpetology and in 1947 became Superintendent of the Z.S.I. and then Director after Baini Prashad moved to become an advisor to the government. He was elected a Fellow of the Royal Society of Edinburgh in 1929. His proposers were James Hartley Ashworth, John Stephenson, Charles Henry O'Donoghue and James Ritchie. He died on 8 December 1955. Works The ''Satpura hypothesis'', a zoo-geographical hypothesis proposed by him that suggests that the central Indian Satpura Range of hills acted as a bridge ...

South Asian River Catfish
Erethistidae are a family of catfishes that originate from southern Asia. It includes about 45 species. Taxonomy This family includes species previously placed in Sisoridae. They were removed because they were thought to be more closely related to the neotropical Aspredinidae than to the remaining sisorids due to a number of morphological characters. However, it has been suggested that the erethistid catfishes be included back into Sisoridae and some genera are included in that family by some authorities. Distribution Erethistids are found on the Indian subcontinent eastwards to western Thailand and northern Malay Peninsula. Description Many of the members of this family are small, cryptically colored fishes with tuberculate skin. Erethistids are distinguished from sisorids by having a pectoral girdle with a long coracoid process that extends well beyond the base of the pectoral fin; this structure can be felt through the skin in all genera and is visible externally in all gen ...

Endemism
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
India
India, officially the Republic of India (Hindi: ), is a country in South Asia. It is the seventh-largest country by area, the second-most populous country, and the most populous democracy in the world. Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the north; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives; its Andaman and Nicobar Islands share a maritime border with Thailand, Myanmar, and Indonesia. Modern humans arrived on the Indian subcontinent from Africa no later than 55,000 years ago., "Y-Chromosome and Mt-DNA data support the colonization of South Asia by modern humans originating in Africa. ... Coalescence dates for most non-European populations average to between 73–55 ka.", "Modern human beings—''Homo sapiens''—originated in Africa. Then, int ...

Rihand River
The Rihand River (also referred to as Renu, Renuka, Rend, Rer or Rehar) is a tributary of the Son River and flows through the Indian states of Chhattisgarh and Uttar Pradesh. Its old name was Renu or Renuka. Course The Rihand rises from Matiranga hills, in the region south west of the Mainpat plateau, which is about 1,100 meters above mean sea level. The river flows north roughly through the central part of Surguja & Surajpur district for . The Rihand and its tributaries form a fertile plain in the central part of the district stretching from its origin to Lakhanpur, Surajpur, Pratappur. Thereafter, it flows north into Sonbhadra district of Uttar Pradesh via Singrauli district of Madhya Pradesh, where it is called Rhed and finally joins the Son. Tributaries it is principal tributaries in Surajpur district are the Mahan, the Morana (Morni), the Geur, the Gagar, the Gobri, the Piparkachar, the Ramdia and the Galphulla. Many seasonal and perennial rivers join the Rihand rese ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sone River
Son River ( hi, सोन नदी, also spelt Sone River) is a perennial river located in central India. It originates near Amarkantak Hill in Gaurela-Pendra-Marwahi district of Chhattisgarh and finally merges with the Ganges River near Patna in Bihar. Sone river is the second-largest southern tributary of the Ganges' after Yamuna River. India's oldest river bridge Koilwar Bridge over Sone River connects Arrah with Patna. Sone river is famous for its sand across country. Multiple dam(s) and hydro-electric projects run on its course towards Ganges. Course Sone River is called 'सोन / सोने' in Hindi, but called 'शोण' in Sanskrit, a rare instance of an Indian river having masculine name. Damodar and Brahmaputr also have masculine name. The Sone originates near Pendra in Chhattisgarh, just east of the headwater of the Narmada River, and flows north-northwest through Shahdol district in Madhya Pradesh state before turning sharply eastward where it enco ...

Fish Measurement
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. Simply put, this measurement excludes the length of the caudal (tail) fin. * Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes (lampreys), and (usually) Elasmobranchii (sharks and rays), as well as some other fishes.

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 ...
