Great Crested Newt Triturus cristatus
Great crested newts are the largest of the UK's three native species, growing up to 17cm in length. They are dark brown or black in colour with a distinct ‘warty’ skin. The underside is bright orange with irregular black blotches. In the spring, males develop an impressive jagged crest along their back and a white 'flash' along the tail.
