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.
Red-tailed knobby newt
The red-tailed knobby newt is a highly toxic newt. They can kill a human that has a weak body or a baby.
The Kweichow Crocodile Newt (T.kweichowensis) is part of the Genus known Tylototriton which consists of 11 known subspecies and possibly even more yet to be named. All Tylototriton are considered highly toxic due to their defense mechanism which is being able to use the tips of its ribs to pierce the insides of the Orange Warts along its sides which secrete the toxin. However they are a fairly docile species so this rarely can happen.
