what is the largest arctic land mammal?
Arctic animals are those that have adapted physically and behaviourally to the particular conditions of life in the most northerly regions on the planet. Evolution Modern arctic land fauna in Canada may be traced back to the Pleistocene epoch (see Ice Age). A few thousand years ago, during the last continental glaciation, thick sheets of ice covered most of Canada and much of the northern United States. Arctic animals have descended from species that occupied land that revegetated after the retreat of the ice. Habitat The Arctic is that part of the world lying north of the Arctic Circle, beyond which there is at least one day of the year when the sun never sets and one when it never rises.
