Wolves live in a variety of biomes, so long as food is plentiful and the temperature is relatively cold. This includes Alaska, much of Canada, and a large portion of Russia, as well as some parts of Europe and even Africa.
Although there are technically three species of wolves, two of them, the red wolf and the Abyssinian wolf, have very small populations located to only one geographical area.
The main species of wolf is the gray wolf, which is further divided into five subspecies. Alaskan wolves live in Alaska and Western Canada, while Arctic wolves live in the Canadian Arctic islands. The Great Plains wolves live throughout Canada and the US, and the Eastern wolves live in Southern Canada and the Eastern US. Finally, the Mexican wolf once lived in Mexico and the Southern US, but is almost completely extinct.
