The snow leopard, or irbis, is a large cat with thick fur and a long tail. It lives high in the mountains of Central Asia and is well adapted to cold climates.
The snow leopard differs from other cats with its long tail and life at high altitudes in cold mountains. It is important for nature as a hunter that regulates the number of herbivores.
