The marbled newt (Triturus marmoratus) is a mainly terrestrial newt native to Europe.
Marbled newts have dark brown or black bodies with irregular patterns of green. They have black bellies with off-white specks. Adult females have an orange stripe running down the back from the head to the tip of the tail. Juveniles also have this stripe, but it fades on males at about 9 months. Breeding males have a large wavy crestthat runs from its neck down to the tip of its tail, but is a little bit shorter where the tail meets the body. The crest is striped yellowish-white with black. Adult marbled newts are from 5 inches (13 cm) to 6.5 inches (17 cm) long.
