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.
They measure 6 to 9 cm (2.4 to 3.5 in) in snout-to-vent length, and 11 to 18 cm (4.3 to 7.1 in) overall. [3] They are similar to the California newt ( Taricha torosa ) but differ in having smaller eyes, yellow irises, V-shaped tooth patterns, and uniformly dark eyelids. [ 2 ]
Also, rough-skinned newts' upper teeth form a V shape, while those of the California newt form a Y shape, but this is difficult to ascertain on a living specimen. [4] The red-bellied newt is brown on the upper body with a red underbelly, has grainy skin, and grows to between 5.5 and 7.5 in (14 and 19 cm).
The range of Tylototriton anguliceps. The angular-headed newt can be found inhabiting three different countries: Vietnam, Laos, and Thailand. [2] It was initially discovered in Mường Nhé District and Thuận Châu District in Vietnam and Doi Lahnga, a mountain in the Chiang Mai Province in Thailand, in 2015. [3]
The olm (German: ⓘ) or proteus (Proteus anguinus) is an aquatic salamander which is the only species in the genus Proteus of the family Proteidae [2] and the only exclusively cave-dwelling chordate species found in Europe; the family's other extant genus is Necturus.
The common mudpuppy (Necturus maculosus) is a species of salamander in the family Proteidae. [3] It lives an entirely aquatic lifestyle in parts of North America in lakes, rivers, and ponds. It goes through paedomorphosis and retains its external gills . [ 4 ]
It has been introduced into the Bavarian Forest in Germany. [1] Where their ranges overlap, it often hybridises with the smooth newt (Lissotriton vulgaris), the offspring being intermediate in appearance between the two species. [2] The Carpathian newt prefers wet, shady woodland, both coniferous and broadleaf, glades, woodland edges and upland ...
Tylototriton shanjing, the emperor newt, Mandarin newt or Mandarin salamander, is a highly toxic newt native to Yunnan and parts of South China.
