Description

Male Alpine newt in water phase

During the mating season early in the year, the males exhibit blue colouring on their backs; their flanks are stippled black and white, and on the belly are marked with a blue stripe. The shallow crest is alternately spotted yellow and black. The females, in water camouflage, are mottle grey-brown-green and have some weak spotting on the back. The belly side of both sexes is bright orange to vermillion and always unmarked. The biggest of the males can reach up to nine, and the females up to twelve centimeters in length. After the mating season, older specimens have a darker, almost black, velvety skin (land camouflage).Prince Newton aka EVERETT!

Life and Habitat

Alpine newts typically inhabit forests with good access to water in hilly to mountainous regions. They are mostly absent in forest-poor areas. They populate well in thick deciduous forests, as well as parkland and natural gardens. Outside the spawning season, Alpine newts live terrestrially. During the day it stays in all kinds of undergrowth, but during the mating season in cool water (forest pools, artificial pools). After the adults come out of winter dormancy, they migrate to their spawning pools.

Distribution

Range map

Alpine newts were originally confined to Central Europe and mountainous Southern Europe, as well as an isolated area on the northern Iberian Peninsula. The species was introduced to southern England in the 1930s and several populations have become established as far north as Sunderland.[2]

Taxonomy

Female Alpine newt in water phase

The Alpine Newt was formerly placed within the genus Triturus. García-París et al.[3] divided the genus Triturus, placing the Alpine Newt into its own genus Mesotriton. Later Mesotriton was postulated to be a junior synonym of Ichthyosaura.[4] Ten subspecies of the Alpine Newt are recognized (some only with neotenic forms).
