Caribou and reindeer are the same species, reindeer being a domesticated, smaller variety or caribou and classified scientifically as a subspecies.
A reindeer is known to paw at the snow to uncover its food, even when two or three feet (0.6–0.9 m) cover the plants. How does the reindeer know to do this? God designed it this way. The reindeer’s coat is made of dense, short hair that is hollow, enabling it to hold air and shed water, making it perfect for the colder temperatures where the reindeer lives.
