Andrias
''Andrias'' is a genus of giant salamanders. It includes the largest salamanders in the world, with ''A. japonicus'' reaching a length of , and ''A. sligoi'' reaching . While extant species are only known from East Asia, several extinct species in the genus are known from late Oligocene and Neogene aged fossils collected in Europe and North America, indicating that the genus formerly had a much wider range. Taxonomy The generic name derives from Ancient Greek ἀνδριάς, "statue". The former name was ''Megalobatrachus'', from Ancient Greek meaning "giant frog". Species Extant Based on genetic evidence, there may be more extant species in the genus. A study in 2018 found that ''A. davidianus'' ''sensu lato'' was a species complex In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear.

Giant Salamander
The Cryptobranchidae are a family of fully aquatic salamanders commonly known as the giant salamanders. They include the largest living amphibians. The family is native to China, Japan, and the eastern United States. They constitute one of two living families within the Cryptobranchoidea, one of two main divisions of living salamanders, the other being the Asiatic salamanders belonging to the family Hynobiidae. The largest species are in the genus ''Andrias,'' native to east Asia''.''

Andrias Scheuchzeri
''Andrias scheuchzeri'' is an extinct species of giant salamander belonging to the genus ''Andrias'', which also contains the closely related living Asian giant salamanders. It is known from Oligocene to Pliocene aged deposits primarily from Central Europe, but possibly as far east as Western Siberia and eastern Kazakhstan. History In his book ''Lithographia Helvetica'' from 1726, Johann Jakob Scheuchzer described a Miocene fossil found in Öhningen as ''Homo diluvii testis'' (Latin: ''Man, witness of the Deluge''), believing it to be the remains of a human that drowned in the biblical Deluge. The fossil was about 1 m (3 ft) long, lacked its tail and hind legs, and could thus be interpreted as showing some resemblance to the remains of a violently trampled human child. In 1758, the first to doubt his theory in print was Johannes Gessner, who thought it was a giant catfish (Siluris). In 1787 Petrus Camper thought it was a lizard (Lacerta); at that time, scholars and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jiangxi Giant Salamander
The Jiangxi giant salamander (''Andrias jiangxiensis'') is a species of very large salamander Endemism, endemic to Jiangxi, Jiangxi Province in China. It is the only Chinese ''Andrias'' species known to have a genetically pure wild population. Discovery and description Prior to 2018, all giant salamanders in China were thought to belong to a single species: the Chinese giant salamander (''A. davidianus''), the largest known amphibian species. However, a major genetic study that year found deep divergences between lineages of the Chinese giant salamander, with many genetically distinct clades restricted to different Drainage basin, river basins, and thus proposed it to be a species complex comprising at least 5 different species. In addition, none of these species were known to have native wild populations, with most wild individuals being releases from salamander breeding farms and belonging to multiple different lineages or hybrids between them. One of the lineages identified i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Andrias Matthewi
''Andrias matthewi'', or Matthew's giant salamander, is an extinct species of giant salamander from the Miocene of North America. It belongs to the genus ''Andrias'', which contains the living Asian giant salamanders. It is the largest salamander to have ever existed, with a maximum estimated length of . Its fossils have been found in Nebraska, Colorado, and Saskatchewan. Taxonomy In 1917, Harold Cook named the new genus and species ''Plicagnathus matthewi'' for a dentary from the "lower Snake Creek beds" of Nebraska. The species was named in honor of William Diller Matthew, who first identified the specimen. In 1963, Joseph Tihen and Charles Chantell named the new species '' Cryptobranchus mccalli'' for two maxillae from the Valentine Formation of Nebraska. Charles Meszoely synonymized ''C. mccalli'' with ''P. matthewi'' and ''Plicagnathus'' with ''Andrias'' in 1966, leading to the current name ''Andrias matthewi''. Bruce Naylor synonymized ''Andrias'' with ''Cryptobranchus'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South China Giant Salamander
The South China giant salamander (''Andrias sligoi'') may be the largest species of salamander and the largest amphibian in the world. It is endemic to southern China, mainly in the Pearl River basin south of the Nanling Mountains. It is extremely endangered and may no longer exist in the wild. Discovery and description It was described in 1924 (as ''Megalobatrachus sligoi'') by Edward George Boulenger from a captive specimen held in the London Zoo. This individual was originally held in the Hong Kong Zoological and Botanical Gardens and may have originated from Guangxi or Guangdong Province, and was likely one of many giant salamanders captured from the mainland and placed in the Botanical Gardens' fountain, all of which had escaped. During a particularly violent storm in April 1920, a large drain pipe in the Gardens burst, carving a large depression into the land that the escaped salamander was washed into. It was captured and kept in a large circular basin, where it was fed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yangtze
The Yangtze or Yangzi ( or ; ) is the longest river in Asia, the third-longest in the world, and the longest in the world to flow entirely within one country. It rises at Jari Hill in the Tanggula Mountains (Tibetan Plateau) and flows in a generally easterly direction to the East China Sea. It is the seventh-largest river by discharge volume in the world. Its drainage basin comprises one-fifth of the land area of China, and is home to nearly one-third of the country's population. The Yangtze has played a major role in the history, culture, and economy of China. For thousands of years, the river has been used for water, irrigation, sanitation, transportation, industry, boundary-marking, and war. The prosperous Yangtze Delta generates as much as 20% of historical GDP of China, China's GDP. The Three Gorges Dam on the Yangtze is the list of the largest hydroelectric power stations, largest hydro-electric power station in the world that is in use. In mid-2014, the Chine ...
