Male ALPINE NEWTs are usually 8 cm, while the females may reach 12 cm. The back of the male is bluish or slate-grey, sometimes with a mottled pattern. During the breeding season the males develop a 1.5-2 mm tall edge along their back, which is yellowish white with regular rows of black dots. On the sides there is a longitudinal stripe of the same colouration as the dorsal edge, under this stripe the sides are azure. The belly is orange without any pattern. The back of the female is greenish, light or darker grey, mottled. It has no dorsal edge and its ventral colouration is similar to that of the males.
