Some reindeer migrate in huge herds from the coastal Arctic to the tundra. Reindeer have a life span of about 10 years in the wild. Reindeer were domesticated in northern Eurasia roughly 2,000 years ago. Today, reindeer are herded by many European and Asian Arctic people. The antlers are shed each year and regrow.
Reindeer have very wide hooves, a broad muzzle, and thick brown fur.
The thick fur traps air, which insulates the reindeer from the cold and helps the reindeer float in water.
