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] |
Salamander
Salamanders are a group of amphibians typically characterized by their lizard-like appearance, with slender bodies, blunt snouts, short limbs projecting at right angles to the body, and the presence of a tail in both larvae and adults. All ten extant salamander families are grouped together under the order Urodela. Salamander diversity is highest in eastern North America, especially in the Appalachian Mountains; most species are found in the Holarctic realm, with some species present in the Neotropical realm. Salamanders rarely have more than four toes on their front legs and five on their rear legs, but some species have fewer digits and others lack hind limbs. Their permeable skin usually makes them reliant on habitats in or near water or other cool, damp places. Some salamander species are fully aquatic throughout their lives, some take to the water intermittently, and others are entirely terrestrial as adults. This group of amphibians is capable of regenerating los ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
