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.
Calotriton
Calotriton, or the European brook newts, is a genus of newts native to the Pyrenees and central Catalonia (Catalan Pre-coastal Range). These amphibians were formerly placed within genus "Euproctus", but the genus was resurrected in 2005. Instead of "Euproctus", they seem more closely related to "Triturus", their sister taxon.
