Zhongjian Yang
Triton Island (; ) is the westernmost and southernmost of the Paracel Islands in the South China Sea. It is located on the southwest corner of Triton Reef and has an area of above sea-level. The reef including the island measures about in area. The island is administered by the People's Republic of China, and is also claimed by the Republic of China (Taiwan) and Vietnam. The island was historically known by the Chinese as ''Bànlù Zhì'' (), and as ''Luó Dǎo'' () to Chinese fishermen. Other Chinese sources have it named as 南建岛, as it was the southernmost point claimed by China until after 1933. The current Chinese name commemorates the Republic of China Navy warship ''ROCS Chung-chien'' () sent in 1946 to claim the Paracel Islands.吕一燃 (Lu Yiran), 2007. 中国近代边界史 (A modern history of China's borders), Vol. 2. 四川人民出版社 (Sichuan People's Publishing), pp.1092-1093.

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 ...

Cyprinidae
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 ...

Yilong Lake
Yilong Lake () is a large freshwater lake located in Shiping County, Honghe Prefecture, Yunnan province, southwestern China. The lake has a surface area of approximately and is particularly notable for its scenery, including the colorful lotus flowers that bloom on its surface. It is located about east of the county seat. The people who live in the vicinity of the lake are largely of the Yi ethnic group. As of the spring of 2013 a severe drought had resulted in substantial lowering of the water level. The lake is one of the most-visited destinations in the Yunnan-Guizhou Plateau. It used to be called Yulong Lake, an allusion to the Yulong Mountain that lies to the lake's south. The change of name has mythological reasons. It is believed that in 1629, the dragon believed to live in the lake ascended to heaven in broad daylight, prompting the change in the lake's name. Not much is known about how the lake formed. Records tell that the lake formed during the Qin and Han dynastie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...

Cyprinus
''Cyprinus'' is the genus of typical carps in family Cyprinidae. Most species in the genus are of East Asia origin with only the common carp (''C. carpio'') in Western Asia and Europe; this invasive species has also been introduced to many other regions around the world. ''Cyprinus'' are closely related to some more barb-like genera, such as ''Cyclocheilichthys'' and ''Barbonymus'' (tinfoils). The crucian carps (''Carassius'') of western Eurasia, which include the goldfish (''C. auratus''), are apparently not as closely related. This genus's most widespread and well-known member is the common carp (''C. carpio'') species complex. Although traditionally considered a single species, recent authorities have split the European and West Asian populations from the East Asian, with the latter named '' C. rubrofuscus'' ( syn. ''C. carpio haematopterus''). Members of the species complex are famed as a food fish and have been widely traded and introduced since antiquity, but in certain a ...

Fish Described In 1977
Fish are Aquatic animal, aquatic, craniate, gill-bearing animals that lack Limb (anatomy), limbs with Digit (anatomy), digits. Included in this definition are the living hagfish, lampreys, and Chondrichthyes, 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 vertebrate, 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 placodermi, external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinct Animals Of China
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freshwater Fish Of China
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. ...
