Cyprinid
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family. It includes the carps, the true minnows, and relatives like the barbs and barbels. Cyprinidae is the largest and most diverse fish family and the largest vertebrate animal family in general with about 3,000 species, of which only 1,270 remain extant, divided into about 370 genera. Cyprinids range from about 12 mm in size to the giant barb (''Catlocarpio siamensis''). By genus and species count, the family makes up more than two-thirds of the ostariophysian order Cypriniformes. The family name is derived from the Greek word ( 'carp'). Biology and ecology Cyprinids are stomachless fish with toothless jaws. Even so, food can be effectively chewed by the gill rakers of the specialized last gill bow. These pharyngeal teeth allow the fish to make chewing motions against a chewing plate formed by a bony process of the skull. The pharyngeal teeth are unique to each species and are used by scient ...

Fish
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 ...

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 ...

Imphal Valley
Imphal Valley ( mni, Imphal Tampak) or Manipur Valley ( mni, Manipur Tampaak) is located in the Indian state of Manipur and is an irregular almost oval shaped canyon that was formed as a result of the multiple small rivers that originate from neighbouring hill regions surrounding the valley and flow through it. The water in the Imphal valley is fetched from several rivers that flows via the valley, such as Imphal River, Iril River, Thoubal River, Khuga River and Sekmai river. Imphal River is the most prominent of the rivers which pass through the heart of the valley, and the river for which the entire valley is named. The Imphal valley is located in almost the centre of the state of Manipur and is surrounded by hills on all sides. Manipur has multi-topographical characteristics; it is a part of the eastern Himalayas, especially its lower hills, and it is an important feature of the landscape of Manipur. The hills form one of the two main physical regions of the state. The other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manipur
Manipur () ( mni, Kangleipak) is a state in Northeast India, with the city of Imphal as its capital. It is bounded by the Indian states of Nagaland to the north, Mizoram to the south and Assam to the west. It also borders two regions of Myanmar, Sagaing Region to the east and Chin State to the south. The state covers an area of . Manipur has been at the crossroads of Asian economic and cultural exchange for more than 2,500 years. It connects the Indian subcontinent and Central Asia to Southeast Asia, East Asia, Siberia, regions in the Arctic, Micronesia and Polynesia enabling migration of people, cultures and religions. During the days of the British Indian Empire, the Kingdom of Manipur was one of the princely states. Between 1917 and 1939, some people of Manipur pressed the princely rulers for democracy. By the late 1930s, the princely state of Manipur negotiated with the British administration its preference to continue to be part of the Indian Empire, rather than part of B ...

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. Total length meas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pethia
''Pethia'' is a genus of small freshwater fish in the family Cyprinidae native to South Asia, East Asia (only Pethia stoliczkana recorded) and Mainland Southeast Asia. Some species are commonly seen in the aquarium trade. The name ''Pethia'' is derived from the Sinhalese ''"pethia"'', a generic word used to describe any of several small species of cyprinid fishes.Pethiyagoda, R., Meegaskumbura, M. & Maduwage, K. (2012)A synopsis of the South Asian fishes referred to ''Puntius'' (Pisces: Cyprinidae).''Ichthyological Exploration of Freshwaters, 23 (1): 69-95.'' Most members of this genus were included in ''Puntius'', until it was revised in 2012.
