Reindeer
The reindeer (Rangifer tarandus), also known as caribou in North America, is a species of deer with circumpolar distribution, native to Arctic, Subarctic, tundra, boreal and mountainous regions of northern Europe, Siberia, and North America. This includes both sedentary and migratory populations.
While overall widespread and numerous, some of its subspecies are rare and at least one has already become extinct.
Reindeer vary considerably in colour and size. In most populations, both sexes grow antlers annually, but females lack antlers in a few. Antlers are typically larger on males.
Hunting of wild reindeer and herding of semi-domesticated reindeer (for meat, hides, antlers, milk and transportation) are important to several Arctic and Subarctic peoples. In parts of Sápmi, reindeer pull pulks. In Christmas folklore, Santa Claus's flying reindeer are well known for pulling his sleigh.
Name etymology
The name Rangifer, which Carl Linnaeus chose for the reindeer genus, was used by Albertus Magnus in his De animalibus, fol. Liber 22, Cap. 268: "Dicitur Rangyfer quasi ramifer". This word may go back to a Saami word raingo. For the origin of the word tarandus, which Linnaeus chose as the specific epithet, he made reference to Ulisse Aldrovandi's Quadrupedum omnium bisulcorum historia fol. 859–863, Cap. 30: De Tarando (1621). However, Aldrovandi – and before him Konrad Gesner – thought that rangifer and tarandus were two separate animals. In any case, the tarandos name goes back to Aristotle and Theophrastus – see 'In history' below.
