Tylototriton vietnamensis | |
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. [1] [2] However, based on molecular genetic data, its closest relative is T. hainanensis . [3]
Tylototriton vietnamensis is a small newt, with total length 12 cm (4.7 in). [2]
The main threat to this species is habitat degradation. [1]
The palmate newt is a species of newt found in Western Europe, from Great Britain to the northern Iberian Peninsula. It is 5–9.5 cm (2.0–3.7 in) long and olive or brown with some dark spots. The underside is yellow to orange, and the throat, unlike in the similar smooth newt, always unspotted. A dark stripe runs along the head and through the eyes. Breeding males develop a distinct filament on the end of their tail, strongly webbed hind feet, and a low, smooth crest on their back.
Salamandridae is a family of salamanders consisting of true salamanders and newts. Salamandrids are distinguished from other salamanders by the lack of rib or costal grooves along the sides of their bodies and by their rough skin. Their skin is very granular because of the number of poison glands. They also lack nasolabial grooves. Most species of Salamandridae have moveable eyelids but lack lacrimal glands.
Xanthocyparis is a genus of cypresses in the family Cupressaceae. As of August 2021, it has only one species, Xanthocyparis vietnamensis, native to Vietnam and southeast China. It is commonly known as the Vietnamese golden cypress. The Nootka cypress, Cupressus nootkatensis or Callitropsis nootkatensis, was also placed in the genus, but this has been rejected.
The alpine newt is a species of newt native to continental Europe and introduced to Great Britain and New Zealand. Adults measure 7–12 cm (2.8–4.7 in) and are usually dark grey to blue on the back and sides, with an orange belly and throat. Males are more conspicuously coloured than the drab females, especially during breeding season.
Tylototriton shanjing, the emperor newt, Mandarin newt or Mandarin salamander, is a highly toxic newt native to Yunnan and parts of South China. It is sometimes seen in private collections, and is sometimes available for sale at certain reptile and amphibian-specializing pet stores and occasionally through captive breeders.
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 38 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.
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 Wenxian knobby newt or Wenxian knobby salamander is a species of salamander in the family Salamandridae. It is endemic to central China. Its type locality is Wen County in Gansu, or in Chinese: 文县; pinyin: Wénxiàn, hence the name.
A newt is a salamander in the subfamily Pleurodelinae. The terrestrial juvenile phase is called an eft. Unlike other members of the family Salamandridae, newts are semiaquatic, alternating between aquatic and terrestrial habitats. Not all aquatic salamanders are considered newts, however. More than 100 known species of newts are found in North America, Europe, North Africa and Asia. Newts metamorphose through three distinct developmental life stages: aquatic larva, terrestrial juvenile (eft), and adult. Adult newts have lizard-like bodies and return to the water every year to breed, otherwise living in humid, cover-rich land habitats.
Tylototriton notialis, also known as the Laos knobby newt, southern crocodile newt, or Khammouan crocodile newt, is a species of newt in the family Salamandridae. It is only known from Khammouane province, central Laos. The Vietnamese record has been described as a new species, Tylototriton thaiorum.
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.
Crocodile newt may refer to:
Tylototriton uyenoi, the Chiang Mai crocodile newt, is a newt endemic to Chiang Mai Province, Thailand. It was distinguished from Tylototriton shanjing, the emperor newt, in 2013. The species was named in honor of herpetologist Shun-ichi Ueno. T. uyenoi is one of the few salamander species endemic to Thailand.
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" or "Klingon newt", as it resembles the ridges on the head of the fictional Klingon species from the television show Star Trek.
Tylototriton ngarsuensis, the Ywangan crocodile newt, is a species of newt in the family Salamandridae that is endemic to Myanmar. It is only known from Ngar Su village, which is located in the vicinity of Ywangan Township.
Tylototriton ngoclinhensis, the Ngoc Linh crocodile newt, is a species of crocodile newt native to the Central Highlands region of Vietnam. First discovered in 2018, it was described as a new species in 2023. Due to its small range, the newt is considered to be threatened and it has been proposed for it to be classified as endangered on the IUCN Red List.
