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. 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 hynobiids than to giant salamanders extend back to the Middle Jurassic.

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, which includes Asian giant salamanders and hellbenders, and Hynobiidae, commonly known as Asian salamanders. Some species of the fully aquatic family Cryptobranchidae are known as giant salamanders due to their large size. 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'' Haifanggou Formation, China, Middle Jurassic (Bathonian) (neotenic, has alternatively been recovered outside of Cryptobranchoidea) *''Jeholotriton'' Haifanggou Formation, China, Middle Jurassic (Bathonian) (neotenic) *''Pangerpeton'' Haifanggou Formation, China, ...

Hynobius Fossigenus
''Hynobius fossigenus'' is a species of salamander in the family Hynobiidae, and is found in some prefectures in Kantō and 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 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 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 metamorphosis within a year. The males become adults around the age of five, while the females ... [...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 lost lim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 res ... as well as by collecting for traditional medicine.
