Gogangra
''Gogangra'' is a genus of sisorid catfishes native to Asia. Taxonomy ''G. viridescens'' was previously placed in the genus '' Nangra''. In 1998, the genus was given the name ''Gangra'', but this name was already preoccupied by the genus ''Gangra'' of lepidopterans, so ''Gogangra'' was proposed as a replacement name in 2001. ''G. laevis'' was described in 2004. Species There are currently two recognized species in this genus: * '' Gogangra laevis'' Ng, 2005 * '' Gogangra viridescens'' (Hamilton, 1822) Distribution ''Gogangra'' species are distributed in the Ganges, Meghna, and Brahmaputra drainages, India and Bangladesh. ''G. viridescens'' is known from the Ganges and Brahmaputra drainages of India and Bangladesh. It is also reported from the Indus drainage in Pakistan, Nepal, and Bhutan. ''G. laevis'' is from the Yamuna and Meghna River drainages of the lower Brahmaputra River drainage in Bangladesh. ''G. viridescens'' is found in the upper reaches of rivers. Description ''G ...

Sisoridae
Sisoridae is a family of catfishes. These Asian catfishes live in fast-moving waters and often have adaptations that allow them to adhere to objects in their habitats. The family includes about 235 species. Taxonomy The family Sisoridae is recognized as a natural, monophyletic group based on morphological and molecular evidence. It is divided into two subfamilies, Sisorinae and Glyptosterninae (glyptosternoids). The Sisorinae contain the five genera ''Bagarius'', ''Gagata'', '' Gogangra'', '' Nangra'', and ''Sisor''. The Glyptosterninae contain three tribes. Glyptothoracini contains only the genus ''Glyptothorax'' and Pseudecheneidina contains only the genus ''Pseudecheneis''. The remaining genera, '' Chimarrichthys'', '' Exostoma'', '' Glaridoglanis'', ''Glyptosternon'', ''Myersglanis'', '' Oreoglanis'', '' Parachiloglanis'', '' Pareuchiloglanis'', and '' Pseudexostoma'', are contained in the tribe Glyptosternina.

Nepal
Nepal (; ne, नेपाल ), formerly the Federal Democratic Republic of Nepal ( ne, सङ्घीय लोकतान्त्रिक गणतन्त्र नेपाल ), is a landlocked country in South Asia. It is mainly situated in the Himalayas, but also includes parts of the Indo-Gangetic Plain, bordering the Tibet Autonomous Region of China to the north, and India in the south, east, and west, while it is narrowly separated from Bangladesh by the Siliguri Corridor, and from Bhutan by the Indian state of Sikkim. Nepal has a diverse geography, including fertile plains, subalpine forested hills, and eight of the world's ten tallest mountains, including Mount Everest, the highest point on Earth. Nepal is a multi-ethnic, multi-lingual, multi-religious and multi-cultural state, with Nepali as the official language. Kathmandu is the nation's capital and the largest city. The name "Nepal" is first recorded in texts from the Vedic period of the India ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Of India
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 ...

Freshwater Fish Genera
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. ...

Palate
The palate () is the roof of the mouth in humans and other mammals. It separates the oral cavity from the nasal cavity. A similar structure is found in crocodilians, but in most other tetrapods, the oral and nasal cavities are not truly separated. The palate is divided into two parts, the anterior, bony hard palate and the posterior, fleshy soft palate (or velum). Structure Innervation The maxillary nerve branch of the trigeminal nerve supplies sensory innervation to the palate. Development The hard palate forms before birth. Variation If the fusion is incomplete, a cleft palate results. Function When functioning in conjunction with other parts of the mouth, the palate produces certain sounds, particularly velar, palatal, palatalized, postalveolar, alveolopalatal, and uvular consonants. History Etymology The English synonyms palate and palatum, and also the related adjective palatine (as in palatine bone), are all from the Latin ''palatum'' via Old French ''palat ...

Barbel (anatomy)
In fish anatomy and turtle anatomy, a barbel is a slender, whiskerlike sensory organ near the mouth. Fish that have barbels include the catfish, the carp, the goatfish, the hagfish, the sturgeon, the zebrafish, the black dragonfish and some species of shark such as the sawshark. Barbels house the taste buds of such fish and are used to search for food in murky water. The word "barbel" comes from the Middle Latin ''barbula'', for "little beard." Barbels are sometimes erroneously referred to as '' barbs'', which are found in bird feathers for flight. Barbels may be located in a variety of locations on the head of a fish. "Maxillary barbels" refers to barbels on either side of the mouth. Barbels may also be nasal, extending from the nostrils. Also, barbels are often mandibular or mental, being located on the chin. In fish, barbels can take the form of small, fleshy protrusions or long, cylindrical shaped extensions of the head of a fish. The cylindrical barbel shapes are bui ...

Pectoral Fin
Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as seen in sharks. Apart from the tail or caudal fin, fish fins have no direct connection with the spine and are supported only by muscles. Their principal function is to help the fish swim. Fins located in different places on the fish serve different purposes such as moving forward, turning, keeping an upright position or stopping. Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling. Fins can also be used for other purposes; male sharks and mosquitofish use a modified fin to deliver sperm, thresher sharks use their caudal fin to stun prey, reef stonefish have spines in their dorsal fins that inject venom, anglerfish use the first spine of their dorsal fin like a fishing rod ...
