Reindeer are sometimes called "camels of the frozen north." These mammals are of the Cervidae family. There genus is Rangifer tarandus. Just like cows, they are even toed ruminants.
Reindeer are domesticated caribou. While some distinctions can be made such as reindeer having shorter, more stout bodies than caribou and coats which are lighter and faces which are flatter, these two animals can in fact mate and create fertile offspring, they are scientifically classified the same way, and both have rather mean dispositions.
Caribou live in various Arctic areas of Europe, Asia, and North America. With the exception of Musk Ox these creatures live further north than any other hoofed animal. They can live within the Arctic Circle migrating from the northern taiga forests in winter to the wind swept tundra in summer
