Paramesotriton, also known as warty newts [1] or Asian warty newts, [2] [3] is a genus of salamanders in the family Salamandridae. [1] The genus is found in southwestern and southern China and in northern Vietnam. [1] [3] Most of the species are endemic to China, and the majority of them have been described recently, since 2008. [3] The genus includes both pond and stream dwellers. [4]

Description

Paramesotriton have a dark brown dorsum [2] with a prominent vertebral ridge, often also a pair of lateral ridges. The tail is high and laterally compressed. [4] Skin texture varies from relatively smooth to very rough. [2] Paramesotriton hongkongensis has toxic skin and ova, as has been shown for many other salamanders. [5]

Salamandridae Family of amphibians

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.

Asiatic salamander

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 unique to Japan.

Chinese fire belly newt Species of amphibian

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.

Fire belly newts

The fire belly newts or fire newts are 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.
