They may be the same species, but these two animals are very different. Many of these differences stem from their relationship with humans throughout history.
Reindeer in Eurasia were domesticated over 2000 years and although some animals remain in the wild, reindeer is a blanket name that includes both the domesticated and wild populations. In Canada, we refer to them as caribou, and almost all of them are wild; the ones that are not are also referred to as reindeer. Domesticated reindeer tend to be shorter and more stout than our wild caribou, with thicker hair.
