Hynobiidae
The Asiatic salamanders (family Hynobiidae) are primitive salamanders found all over Asia, and in European Russia. They are closely related to the giant salamanders (family Cryptobranchidae), with which they form the suborder Cryptobranchoidea. About half of hynobiids currently described are endemic to Japan, but their range also covers parts of China, Russia, Afghanistan and Iran. Hynobiid salamanders practice external fertilization, or spawning. And, unlike other salamander families which reproduce internally, male hynobiids focus on egg sacs rather than females during breeding. The female lays two egg sacs at a time, each containing up to 70 eggs. Parental care is common. A few species have very reduced lungs, or no lungs at all. Larvae can sometimes have reduced external gills if they live in cold and very oxygen-rich water. Fossils of hynobiids are known from the Miocene to the present in Asia and Eastern Europe, though fossils of Cryptobranchoids more closely related to ...

Cryptobranchoidea
The Cryptobranchoidea are a suborder of salamanders found in Asia, European Russia, and the United States. They are known as primitive salamanders, in contrast to Salamandroidea, the advanced salamanders. It has two living subdivisions, Cryptobranchidae ( Asian giant salamanders and hellbenders), and Hynobiidae, commonly known as Asian salamanders. Giant salamanders are obligate paedomorphs with partial metamorphosis, but Asiatic salamander goes through a full metamorphosis. The only known exceptions are the Longdong stream salamander, which has been documented as facultatively neotenic, and the Ezo salamander, where a now assumed extinct population from Lake Kuttarush in Hokkaido had neotenic traits like gills in adults. The oldest members of the group are known from the Middle Jurassic (Bathonian) aged Yanliao Biota of China. Taxonomy This suborder contains only two families at present. All other members are extinct and are only known as fossils. *'' Chunerpeton'' Haifa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hynobius Fossigenus
''Hynobius fossigenus'' is a species of salamander in the family Asiatic salamander, Hynobiidae, and is found in some Prefectures of Japan, prefectures in Kantō region, Kantō and Chūbu region, Chūbu districts in Japan. Like all species in the genus ''Hynobius'', it has lungs, its tail is smaller than its body, and it does not have claws on its fingertips. However, characteristics such as its purplish coloration with golden spots, its size, and its use of River ecosystem, lotic waters to reproduce make this species different from all the others. The individuals breed between December and April in mountain streams surrounded by ''Cryptomeria, Cryptomeria japonica'' evergreen forests. After mating, the females lay their eggs in envelopes, which are thick, transparent, and resistant, where they remain for sixty days, when the embryo fully develops in the egg. After hatching, the tadpoles leave the envelope and start living under rocks or at the bottom of streams, completing their ...

Batrachuperus
''Batrachuperus'' is a genus of salamander in the family Hynobiidae found in western China and adjacent Myanmar. Their common name is stream salamanders or mountain salamanders.

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, the sole surviving order from the group Caudata. ''Urodela'' is a scientific Latin term based on the Ancient Greek : ourà dēlē "conspicuous tail". ''Caudata'' is the Latin for "tailed ones", from : "tail". 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 never 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. So ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cryptobranchidae
The Cryptobranchidae (commonly known as giant salamanders) are a family of large salamanders that are fully aquatic. The family includes some of the largest living amphibians. They are native to China, Japan, and the eastern United States. Giant salamanders constitute one of two living families—the other being the Asiatic salamanders belonging to the family Hynobiidae—within the Cryptobranchoidea, one of two main divisions of living salamanders. The largest species are in the genus ''Andrias'', native to east Asia.

Batrachuperus Karlschmidti
The Chiala mountain salamander (''Batrachuperus karlschmidti'') is a species of salamander in the family Hynobiidae endemic to China and known from northwestern Sichuan, northeastern Tibet, and southeastern Gansu. Its validity as a species distinct from '' Batrachuperus tibetanus'' has been controversial. It is named after Karl Patterson Schmidt, American herpetologist. The species' natural habitat are slow-flowing streams in grassland areas. It is largely aquatic but can occasionally be found on the stream bank. It is threatened by habitat loss caused by overgrazing Overgrazing occurs when plants are exposed to intensive grazing for extended periods of time, or without sufficient recovery periods. It can be caused by either livestock in poorly managed agricultural applications, game reserves, or nature ... as well as by collecting for traditional medicine.

Protohynobius Puxiongensis
The Puxiong salamander (''Pseudohynobius puxiongensis'') is a species of salamander in the family Hynobiidae, endemic to China. It is only known from the vicinity of its type locality, in Puxiong (普雄镇), in Yuexi County, Sichuan Province. The area belongs to the Hengduan Mountains that form the southeastern part of the Qinghai-Tibet Plateau. The Puxiong salamander is a relatively small salamander with a slender body form. History of discovery and taxonomic position The Puxiong salamander was first described in 2000 as ''Protohynobius puxiongensis'', based on a single specimen collected in 1965. Because of a characteristic interpreted as primitive (internasal bone), a new monotypic genus, ''Protohynobius'', in its own subfamily, Protohynobiinae, was established. However, field effort in 2007–2009 revealed new animals that allowed a more detailed analysis. These suggested the holotype from 1965 was slightly unusual, as later specimens did not have an internasal bone while be ...
