Hynobius katoi is a species of salamander in the family Hynobiidae, endemic to Japan. Its natural habitats are temperate forests and rivers.
The Asiatic salamanders are primitive salamanders found all over Asia, and in European Russia. They are closely related to the giant salamanders, with which they form the suborder Cryptobranchoidea. About half of hynobiids currently described are endemic to Japan.
Hynobius yangi, the Kori salamander, is a species of salamander endemic to southeastern South Korea. It is a lentic-breeding species similar to the Korean salamander but is distinguished by factors including tail shape and dorsal coloration. The species is known from the vicinity of the type locality in Gijang County in northeastern Busan and from the nearby Ulju County in western Ulsan.
Hynobius quelpaertensis, the Jeju salamander, also spelled Cheju salamander, is a species of salamander found on various islands and peninsulas off the southwestern coast of the Korean Peninsula, including Jindo, Geojedo, Jejudo, and Namhae. It inhabits moist mountain forests.
Hynobius is a genus of salamander in the family Hynobiidae, occurring in Japan, Korea, China, Taiwan and Far East Russia.
Hynobius arisanensis, the Alishan salamander, is a species of salamander in the family Hynobiidae endemic to Taiwan. It occurs in the Alishan Range, the Yushan Range, and southern Central Mountain Range, where it lives at altitudes of 1,800–3,600 m (5,900–11,800 ft) above sea level. Its natural habitats are temperate forests, rivers, and freshwater springs. It is usually hiding during day time.
The Odaigahara salamander is a species of salamander in the family Hynobiidae. It is endemic to Japan. Its natural habitats are temperate forests, rivers, and freshwater springs. This species is threatened by habitat loss.
The Oita salamander is a species of salamander in the family Hynobiidae endemic to Japan. Named after Oita Prefecture, its natural habitats are temperate forests, rivers, intermittent rivers, freshwater marshes, intermittent freshwater marshes, and irrigated land in western Japan. It is threatened by habitat loss, due to the increasing construction of homes within its habitat. The Oita Salamander is considered to be vulnerable by the (IUCN) Red List of Threatened Species with a declining population.
Hynobius formosanus, the Taiwan salamander, is a species of salamander in the family Hynobiidae, endemic to Taiwan, where it occurs in the high mountains at around 2,100 m (6,900 ft). Its natural habitats are from open alpine habitats to shaded moist evergreen forests. Adults have a total length of 58–98 mm (2.3–3.9 in).
The Hakuba salamander or Japanese mountain salamander is a species of salamander in the family Hynobiidae. This salamander is also synonymous with the mountain salamander. It is endemic to Japan. Its natural habitats are temperate forests, rivers, swamps, freshwater springs, and plantations. It is threatened by habitat loss.
The Hida salamander or Hondo salamander is a species of salamander in the family Hynobiidae, the Asiatic salamanders. It is endemic to central and western Honshu, Japan. It lives in deciduous, coniferous, and mixed forests, where it breeds in streams. The egg sacs of this species were reported to display blue-to-yellow iridescent glow due to a quasi-periodic diffraction grating structure embedded within the enveloppes of the egg sacs. These salamanders typically spawn from February to April, leading some to metamorphose in late September while others wait for the following year to do so after winter is over.
The Tohoku salamander is a species of salamander in the family Hynobiidae, endemic to Japan. Its natural habitats are temperate forests and rivers.
Hynobius naevius, also known as the spotted salamander, Sagami salamander, Japanese salamander, and blotched salamander, is a species of salamander in the family Hynobiidae. It is endemic to northwestern Kyushu, Japan. Earlier records from Honshu represent other species.
Hynobius nebulosus, the Mitsjama salamander, is a species of salamander in the family Hynobiidae endemic to Japan. Its natural habitats are temperate forests, rivers, swamps, freshwater springs, and irrigated land. It is threatened by habitat loss.
The Oki salamander is a species of salamander in the family Hynobiidae, endemic to Japan. Its natural habitats are temperate forests, rivers, and plantations. It is threatened by habitat loss.
Hynobius sonani, the Taichu salamander, is a species of salamander in the family Hynobiidae, endemic to Taiwan, where it occurs in the Central Mountain Range above 2,750 m (9,020 ft). Its natural habitats are from open alpine habitats to shaded moist evergreen forests; it breeds in streams.
The amber salamander, amber-colored salamander, tortoiseshell salamander, or Stejneger's oriental salamander is a species of salamander in the family Hynobiidae, endemic to Japan. Its natural habitats are temperate forests and rivers. It is threatened by habitat loss.
The Tokyo salamander is a species of salamander in the family Hynobiidae, endemic to Japan. Its natural habitats are temperate forests, freshwater springs, arable land, irrigated land, and canals and ditches. It is threatened by habitat loss. Many different species of amphibian have unbalanced sex ratios. This trend is no different in Hynobius Tokyoensis; the sex ratio between males and females is about 1.5:1. Although this does not play as large of a role as habitat destruction when it comes to the decline of this species, it is still significant. Considering their environmental preferences, they are usually found in paddy fields. Mid-Summer drainage from these fields hinders the population's ability to thrive as this would occur before these populations could complete metamorphosis.
The Tsushima salamander is a species of salamander in the family Hynobiidae, endemic to Japan. Its natural habitats are temperate forests and rivers.
The Xingan salamander is a species of salamander in the family Hynobiidae, endemic to China: it is only known from its type locality, Mao'ershan in the Xing'an County, Guangxi. Its natural habitats are marshes and the surrounding forests. It is threatened by habitat loss and, living close to the summit of Mao'ershan at around 2,000 m (6,600 ft) asl, by climate change. It occurs within the Mao'ershan National Nature Reserve.
