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.
Smooth newt
Smooth newts are generalist carnivores with a broad diet including invertebrates, crustaceans, and the eggs and hatchlings of frogs and fish. Therefore, they are likely to prey on and compete for food with a wide range of Australian terrestrial and freshwater species
