Formerly included in Euproctes species occupy a few specialised areas in the Western Mediterranean region and occupy mainly mountainous regions, usually 700-2,500 m although sometimes between 250 and 3,000 m. They usually live close to mountain streams or lakes, or occasionally damp gullies that remain moist. Hibernation takes place below ground in winter, but they may also aestivate in summer. The Brook Salamanders are an earth brown colour with a distinguishing yellow dorsal stripe, thick granular skin and small or vestigial partoid glands.
