Reindeer are native to the Arctic region of North America, including Alaska, northern Canada, and Greenland. They are also found in northern Europe, including Norway, Sweden, Finland, and Russia. Reindeer are well-adapted to the harsh conditions of the Arctic tundra, with their thick coats and antlers that help them survive in the cold weather. Reindeer are also known for their distinctive appearance, with their long legs and large hooves that allow them to move easily through snow.
