Psilorhynchus Pseudecheneis
''Psilorhynchus pseudecheneis'', also known as the Nepalese minnow or stone carp, is a species of freshwater ray-finned fish, a torrent minnow. it inhabits torrential streams and it is adapted to such a habitat by possessing am increased count of simple rays in the pectoral fins and in having transverse folds in the skin on its underside which allow it to cling to rocks in the swift current. It is found in eastern Nepal and has recently been recorded from India, it is a migratory species. The specific name ''pseudecheneis'' is a compound of the Greek ''pseudo'' meaning "false" and ''echeneis'' which means a "sucker fish", probably a reference to the fact that the torrent minnows use their pectoral fin rays to adhere to the substrate rather than having a suckermouth.

Ambat Gopalan Kutty Menon
In the Melanesian mythology of Malekula Island, Vanuatu, Ambat is a culture hero recorded by A.B. Deacon. In the myth, Temes Malau has an ogress wife Nevinbumbaau and had a son Mansip. Nevinbumbaau trapped Ambat's older brothers one after another in a ditch, where they stayed until Ambat came to free them. The same brothers later tried to kill Ambat because they envied him his beautiful wife Lindanda, who learned of her husband's death when she saw blood on the comb he had left her. She escaped from the brothers, who thought they had won (Bonnefoy 1993:96, 99, 103).

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 ...

Psilorhynchus
''Psilorhynchus'' is a genus of fish in the family ''Psilorhynchidae'' native to South Asia. This genus is the only member of its family (biology), family. The members of ''Psilorhynchus'' are small benthic fishes which occur in rivers and streams with fast to swift currents, hence they are often referred to a torrent minnows. They are distributed in southern Asia, in the Indo-Burma region and the Western Ghats. The genus is the sister group to the family Cyprinidae, and with that family the Psilorhynchidae makes up the superfamily Cyprinoidea, with all the other cypriniform families in the superfamily loach, Cobitoidea. Species There are currently 29 recognized species in this genus: * ''Psilorhynchus amplicephalus'' Muthukumarasamy Arunachalam, Arunachalam, Murugan Muralidharan, Muralidharan & Paramasivan Sivakumar, Sivakumar, 2007 * ''Psilorhynchus arunachalensis'' (Kongbrailatpan Nebeshwar-Sharma, Nebeshwar, Kenjum Bagra, Bagra & Debangshu Narayan Das, D.

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 ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...

Ancient Greek Language
Ancient Greek includes the forms of the Greek language used in ancient Greece and the classical antiquity, ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Greek Dark Ages, Dark Ages (), the Archaic Greece, Archaic period (), and the Classical Greece, Classical period (). Ancient Greek was the language of Homer and of fifth-century Athens, fifth-century Athenian historians, playwrights, and Ancient Greek philosophy, philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Homeric Greek, Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form a ...

Suckermouth
In fish, a suckermouth is a ventrally-oriented (inferior) mouth adapted for grazing on algae and small organisms that grow on submerged objects. All Loricariidae possess a suckermouth as do the cypriniform algae eaters of the genus ''Gyrinocheilus'' and other genera. The 'False Siamensis' (Epalzeorhynchus sp. or Garra taeniata) also has this feature. Three genera in Mochokidae, '' Atopochilus'', ''Chiloglanis'', and '' Euchilichthys'', also possess an oral sucker, formed by the lips and part of the barbels. The Loricariidae and members of the genus ''Gyrinocheilus'' are further adapted by having a special opening on the gill cover so that the fish can breathe without using its mouth. Additionally many other fish of the order Cypriniformes have developed a sucking ability to a lesser or greater extent: *The Hillstream loaches (family Balitoridae) have modified fins to attach themselves to a surface and a ventrally located mouth. *The sucker fish (family Catostomidae) also have a mod ...

Fish Described In 1964
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. Mos ...
