Caribou, called reindeer in Europe, live in the arctic regions of Canada, Alaska, Greenland, Scandinavia and Russia. They are small deer which have adapted to polar regions. Their wide hooves help them move easily in the snow and their dense fur protects them from colder temperatures.
Contrary to most deer species, both males and females carry antlers which are covered with velvet in the summer. They eat grass, bark, and lichens. From the arctic regions, the Subarctic of Europe, Asia and North America, this deer species can weigh up to 200 kg for an average height of 1,30 meters. Caribous live in herds and mate at the end of September a little more South from their territory and, in the spring, females give birth between the month of April and May to one to two fawns.
