Fauna of Scotland
Only six amphibians and four land reptiles are native to Scotland. The amphibians include three species of newt: the great crested, of which fewer than 1,000 individuals survive; the smooth, and the palmate. The other amphibians are the common toad, the natterjack toad, found in only four locations in the south-west, and the common frog. A single alien amphibian is known in Scotland, the Alpine newt, a recent escapee confined to the Edinburgh area.
Ziegler's crocodile newt
Ziegler's crocodile newt, Tylototriton ziegleri, is a species of newt in the family Salamandridae. It is so far known from Hà Giang and Cao Bằng provinces in northern Vietnam; there is a photograph to suggest it also occurs in Lào Cai Province. Based on molecular genetic data, Ziegler's crocodile newt belongs to the "Tylototriton asperrimus" group of knobby newts.
