It is {{convert|5–9.5|cm|in|abbr=on}} long and olive or brown with some dark spots. The underside is yellow to orange, and the throat, unlike in the similar [[smooth newt]], always unspotted. A dark stripe runs along the head and through the eyes. Breeding males develop a distinct filament on the end of their tail, strongly webbed hind feet, and a low, smooth crest on their back. [[Habitat]]s include forests, marshes, pastures or gardens. While on land, the newts are mainly [[nocturnal]]. After emerging from [[hibernation]] in spring, they move to stagnant, fish-free water bodies for breeding. After a [[courtship display]], the male deposits a [[spermatophore]] that is picked up by the female. [[Larva]]e develop over after 1.5–3.5 months before [[metamorphosis|metamorphosing]] into land-dwelling juveniles ([[eft]]s). Sexual maturity is reached after two to three years, and the newts can reach a total age of up to 12 years in the wild. The species is overall common and has been assessed as [[Least Concern]] by the [[IUCN]].
