The Chenggong fire belly newt (Cynops chenggongensis) is a species of newt of China. It is only known from its type locality, Shuitan in the Chenggong District of Yunnan. [2]
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 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 eastern newt is a common newt of eastern North America. It frequents small lakes, ponds, and streams or nearby wet forests. The eastern newt produces tetrodotoxin, which makes the species unpalatable to predatory fish and crayfish. It has a lifespan of 12 to 15 years in the wild, and it may grow to 5 in (13 cm) in length. These animals are common aquarium pets, being either collected from the wild or sold commercially. The striking bright orange juvenile stage, which is land-dwelling, is known as a red eft. Some sources blend the general name of the species and that of the red-spotted newt subspecies into the eastern red-spotted newt.
The fire belly newt or fire newt is a genus (Cynops) of newts native to Japan and China. All of the species show bright yellow or red bellies, but this feature is not unique to this genus. Their skin contains a toxin that can be harmful if ingested.
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.
Notophthalmus meridionalis, the black-spotted newt or Texas newt, is a species of aquatic newt native to northeastern Mexico and southern Texas in the United States.
The Chuxiong fire-bellied newt is a species of salamander in the family Salamandridae that is endemic to China where it is only found in Guizhou and Yunnan. It also occurs in Kunming Lake.
The Dayang newt is a rare species of salamander in the family Salamandridae, endemic to China. It is known from Jiexi County in eastern Guangdong from where it was collected in 1936 and described as a new species in 1983. More recently, it has also been found from Dehua County in central Fujian.
The Yunnan lake newt is an extinct species of newt in the family Salamandridae, and was also known as Wolterstorff's newt. It was only found near the Kunming Lake in Yunnan, China. It was found in shallow lake waters and adjacent freshwater habitats. Despite extensive surveys, it has not been seen since 1979, and is therefore considered extinct. The reasons for its extinction are believed to be habitat loss, pollution, and introduced species.
Neurergus kaiseri, the Luristan newt, Kaiser's mountain newt, Kaiser's spotted newt or emperor spotted newt, is a species of very colourful salamander in the family Salamandridae. It is endemic to the southern Zagros Mountains in Iran where it is known from just four streams. Populations of this newt have been declining and the International Union for Conservation of Nature has rated it as "vulnerable". A captive breeding programme has been established in several zoos.
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 Laos warty newt, Laotriton laoensis, is a species of salamander in the family Salamandridae. It is found only in the Saysomboun Special Zone and Phou Kout District in Xiangkhouang Province, Laos. Its natural habitats are subtropical or tropical dry shrubland and rivers. In 2014, it is classed as Endangered.
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.
The Fuding fire belly newt is a rare species of newt in the family Salamandridae, endemic to China. It is only known from Fuding in northeastern Fujian, from the locality where it was described as a new species in 2010. Although it is genetically similar to the Chinese fire belly newt, it is morphologically more similar to the Dayang fire belly newt. The range of C. fudingensis is separate from both other species.
Batrachochytrium salamandrivorans (Bsal) is a pathogenic chytrid fungus that infects amphibian species. Although salamanders and newts seem to be the most susceptible, some anuran species are also affected. Bsal has emerged recently and poses a major threat to species in Europe and North America.
