The reindeer is the only domesticated deer in the world, though it may be more accurate to consider reindeer as semi-domesticated. Reindeer in northern Fennoscandia (northern Norway, Sweden and Finland) as well in the Kola Peninsula and Yakutia in Russia, are all semi-wild domestic reindeer ("Rangifer tarandus f. domesticus"), ear-marked by their owners. Some reindeer in the area are truly domesticated, mostly used as draught animals (nowadays commonly for tourist entertainment and races, traditionally important for the nomadic Sámi). Domesticated reindeer have also been used for milk, e.g. in Norway.
