The smooth newt, European newt, northern smooth newt or common newt is a species of newt. It is widespread in Europe and parts of Asia, and has been introduced into Australia. Individuals are brown with a spotted underside that ranges in color from orange to white. They reach an average length of 8–11 cm (3.1–4.3 in); males are larger than females. The newts' skins are dry and velvety when they are living on land, but become smooth when they migrate into the water to breed. Males develop a more vivid colour pattern and a conspicuous skin seam (crest) on their back when breeding.
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.
The northern crested newt, great crested newt or warty newt is a newt species native to Great Britain, northern and central continental Europe and parts of Western Siberia. It is a large newt, with females growing up to 16 cm (6.3 in) long. Its back and sides are dark brown, while the belly is yellow to orange with dark blotches. Males develop a conspicuous jagged crest on their back and tail during the breeding season.
The sword-tail newt is a species of true salamander from the Ryukyu Archipelago in Japan. It has recently been placed on Japan's Red List of Threatened Amphibians. Sword-tail newts are poisonous, and may also be referred to as fire-bellied newts due to the orange coloration of their underside. They are not to be confused with the common Chinese and Japanese species. It is distinguished from these two species by their larger size, broader heads and smoother skin. Its coloration ranges from brown to black, occasionally with an orange dorsal stripe. Some individuals may have light spotting or speckling on their backs.
The Chinese fire belly newt is a small black newt, with bright-orange aposematic coloration on their ventral sides. C. orientalis is commonly seen in pet stores, where it is frequently confused with the Japanese fire belly newt due to similarities in size and coloration. C. orientalis typically exhibits smoother skin and a rounder tail than C. pyrrhogaster, and has less obvious parotoid glands.
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.
The spotted paddle-tail newt is an amphibian native to southeastern China; it was named in 1876. A member of the family Salamandridae, it is closely related to the spotless paddle-tail newt. The spotted paddle-tail newt lives in streams and is characterized by its long, paddle-shaped tail used for propulsion.
The Japanese fire belly newt is a species of newt in the family Salamandridae endemic to Japan. It is commonly confused with the Chinese fire belly newt due to similarities in coloring and size, and most newts sold as Japanese fire belly newts are likely to be the more commonly collected Chinese fire belly newt instead. It is extremely toxic - fatal within 6 hours - to humans and other animals.
The Hong Kong warty newt or Hong Kong newt is the only species of salamander, found in Hong Kong. Once thought to be endemic to the territory, the species has also been found in the coastal parts of Guangdong Province.
The spot-tailed warty newt is a species of salamander in the family Salamandridae only found in central China. Its natural habitats are subtropical or tropical moist lowland forests and rivers. It is threatened by habitat loss. Female spot-tailed warty newts reach a total length of 155 mm (6.1 in), males are slightly shorter.
Paramesotriton, also known as warty newts or Asian warty newts, is a genus of salamanders in the family Salamandridae. The genus is found in southwestern and southern China and in northern Vietnam. Most of the species are endemic to China, and the majority of them have been described recently, since 2008. The genus includes both pond and stream dwellers.
The Chinese warty newt is a species of salamander in the family Salamandridae. It is found only in China, with a range extending from Chongqing to Hunan, Anhui, Zhejiang, Fujian, Guangdong, and Guangxi Provinces in Central China. Its natural habitats are subtropical or tropical moist lowland forests, rivers, and freshwater marshes. It is threatened by habitat loss. Female Chinese warty newts reach total length of 151 mm (5.9 in), males are slightly shorter.
Paramesotriton guangxiensis, the Guangxi warty newt, is a species of salamander in the family Salamandridae. It is found only in China: it is only known from Paiyangshan, Ningming County, in Guangxi Province. Its natural habitats are subtropical or tropical moist lowland forests and rivers. It is threatened by habitat loss.
The Carpathian newt, or Montandon’s newt, is a species of salamander in the family Salamandridae found in Czech Republic, Poland, Romania, Slovakia, and Ukraine.
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.
Pachytriton, also known as the paddle-tail newts or Chinese newts, is a genus of salamanders in the family Salamandridae. They are found in southeastern China.
Pachytriton inexpectatus is a species of salamander in the family Salamandridae. It is endemic to southern China and found in the Guizhou, Hunan, Guangdong, and Guangxi provinces. Its type locality is Mount Dayao of Jinxiu Yao Autonomous County, Guangxi. Prior to naming of this species in 2011, it was confused with Pachytriton labiatus. It is one of the several species that can appear in the pet trade as paddletail newt. The specific name inexpectatus is Latin meaning "unexpected" and refers to finding a species that is common in pet trade but lacked formal scientific description. Common name Yaoshan stout newt has been coined specifically for this species.
Paddletail newt or paddle-tail newt is a name used in pet trade for several species of newts in the following two genera:
