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.
Wildlife of Alaska
The Taricha Granulosa, or Rough-Skinned Newt, is a salamander in the caudata order. This newt is multicolored, typically light brown on the back and yellow bellied, but can sometimes be olive green on the back. The Rough-Skinned Newt is capable of growing up to 26.1 centimeters and will typically reach at least 12.7 centimeters. The newt's name comes from the granular and rough texture on their skin. The skin on the newt is toxic and releases a powerful neurotoxin called Tetrodotoxin, which can effect mucous glands and skin.
