The small-mouth salamander is a species of mole salamander found in the central United States, from the Great Lakes region in Michigan to Nebraska, south to Texas, and east to Tennessee, with a population in Canada, in Pelee, Ontario. It is sometimes referred to as the Texas salamander, porphyry salamander, or the narrow-mouthed salamander. The Kelley's Island salamander was synonymized with A. texanum in 1995.
The Japanese giant salamander is a species of salamander in the family Cryptobranchidae. The species is endemic to Japan, where it is known as Ōsanshōuo (オオサンショウウオ/大山椒魚), literally meaning "giant salamander". With a length of up to 5 feet (1.5 m), it is the third-largest salamander in the world, only being surpassed by the very similar and closely related Chinese giant salamander and South China giant salamander. There are currently only five known members of the family Cryptobranchidae: the Japanese, Chinese, and South China giant salamanders, an undescribed Andrias species from eastern China, and the hellbender.
Tylototriton shanjing, the emperor newt, Mandarin newt or Mandarin salamander, is a highly toxic newt native to China.
Tylototriton verrucosus is a species of newt found in the Indian subcontinent and Southeast Asia. Common names include: Himalayan newt, crocodile newt, crocodile salamander, Himalayan salamander, red knobby newt.
Tylototriton is a genus of newts known as crocodile newts or knobby newts. About 25 known species are in this genus. Many species have been described just recently. They range from northeastern India and Nepal through Burma to northern Thailand, Laos, Vietnam, and southern China.
Anderson's crocodile newt, Anderson's newt, Ryukyu spiny newt, or Japanese warty newt is a species of salamander in the family Salamandridae found in the Ryukyu Islands of Japan, and, at least formerly, Mount Guanyin in northern Taiwan, where it is now believed to be extinct.
The black knobby newt is a species of salamanders in the family Salamandridae found in China and Vietnam. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, freshwater marshes, and intermittent freshwater marshes. It is threatened by habitat loss and overharvesting.
The Hainan knobby newt is a species of salamander in the family Salamandridae. It is found only in the island of Hainan, China. It is known from the Wuzhi Mountains, Diaoluoshan, and Jianfengling. All these locations are nature reserves. Nevertheless, the species is threatened by habitat loss and degradation due to agriculture, clear-cutting and infrastructure development for tourist activities.
The red-tailed knobby newt or Kweichow (crocodile) newt is a species of salamander in the family Salamandridae. It is found in western Guizhou and north-eastern Yunnan, China. It is most closely related to emperor newt and Himalayan newt.
The Taliang knobby newt is a species of salamander in the family Salamandridae. It is found only in southern Sichuan, China. It inhabits densely vegetated forested valleys, where it breeds in pools, ponds and paddy fields. It is a common species within its confined range.
The Nankiang horned toad is a species of frog in the family Megophryidae. It is endemic to northern Sichuan and southern Gansu, China.
The black salamander, also known as the speckled black salamander, is a species of salamander in the family Plethodontidae. It is endemic to the United States. Its natural habitats are temperate forests and temperate grassland. It is threatened by habitat loss.
The blackbelly salamander is a species of salamander in the family Plethodontidae. It is endemic to the United States. Its natural habitats are rivers, intermittent rivers, and freshwater springs. It is threatened by habitat loss.
Tylototriton vietnamensis, the Vietnamese crocodile newt or Vietnamese knobby newt, is a species of newt in the family Salamandridae. It is known from four localities in northern Vietnam where it occurs in and near ponds within dense bamboo vegetation. It is quite likely that it also will be found in adjacent areas of China and possibly Laos. It is possible that specimens earlier identified as T. asperrimus are in fact T. vietnamensis. However, based on molecular genetic data, its closest relative is T. hainanensis.
Tylototriton notialis, the Laos knobby newt, is a species of newt in the family Salamandridae. It is only known from its type locality in the Nakai-Nam Theun Biodiversity Conservation Area, Khammouane Province, central Laos. The type locality is an evergreen mixed deciduous–pine forest; the newts were found in and near a small stream. It is likely that Laos knobby newt will also be found in adjacent areas of Vietnam. Based on molecular genetic data, it belongs to the Tylototriton asperrimus group of knobby newts. Laos knobby newt is a small newt, with total length of about 11–14 cm (4.3–5.5 in).
Tylototriton ziegleri, also known as Ziegler's crocodile newt or Ziegler's knobby newt, is a species of newt in the family Salamandridae. It is currently known from Hà Giang and Cao Bằng provinces in northern Vietnam, although its actual range probably wider; there is a photograph to suggest it also occurs in Lào Cai Province in Vietnam, and its range likely extends to Yunnan in southern China. Based on molecular genetic data, Tylototriton ziegleri belongs to the "Tylototriton asperrimus group" of newts. The specific name ziegleri honours Thomas Ziegler, a German herpetologist.
Tylototriton himalayanus is a species of salamander in the family Salamandridae. It is known from the Ilam District in eastern Nepal, Darjeeling in northwestern India, and western Bhutan. It is one of the only two species of salamanders found in India.
The angular-headed newt, also known as angular-headed crocodile newt, is a species of salamander in the family Salamandridae from Thailand, Laos, and Vietnam. Its unique orange markings help to distinguish it from other species, and also gave it the nickname "Star-Trek newt", as it resembles the ridges on the head of the fictional Klingon species from the television show Star Trek.
