 Because of its large wild spaces, Canada is home to many large mammals, some of which have been extirpated in more densely populated areas, for example large predators such as the grey wolf and the brown bear.Well known as "Canadian" are those mammals that are comfortable in Northern Canada, such as the polar fox, caribou herds, the moose, the wolverine, and muskoxen herds.Other prominent Canadian mammals are the Canada lynx, and the North American beaver, which is a major symbol of Canada.
