Reindeer

Lower risk

While inhabiting arctic tundra and northern boreal forests, this species ia among the most migratory of all animals. They feed on lichens, mushrooms, grasses, horsetails and willow. Reindeer are great swimmers. They also can run up to 50mph (80.5 km/h). They have the spongy foot pads, which provide traction on summer tundra. In the winter pads harden and become covered with tufts of hair, to prevent slipping. Their main predators are wolves, bears, people and wolverines. Reindeer live up to 15 years in the wild and 20 years in captivity.
