The alpine newt (Ichthyosaura alpestris) is a species of newt native to continental Europe and introduced to Great Britain and New Zealand. Adults measure 2.8–4.7 inches and are usually dark grey to blue on the back and sides, with an orange belly and throat. Males are more conspicuously colored than the drab females, especially during breeding season.
Although still relatively common and classified as Least Concern on the IUCN Red List, alpine newt populations are decreasing and have locally gone extinct. The main threats are habitat destruction, pollution and the introduction of fish such as trout into breeding sites.
