The reindeer, also called caribou in Canada, is an imposing animal from its height of 1.3 m at the withers which lives in the arctic and subarctic regions of Europe, Asia or even North America. Its brown or gray coat, made up of hollow hairs, insulates it from the rigors of the cold and its wide hooves are suitable for walking in snow. Within this species, both males and females are endowed with antlers which develop throughout the year before falling with the arrival of winter for males, and spring for females.
