what's the difference between a caribou and a reindeer

Reindeer and caribou are actually the same species, but they have different subspecies and adaptations for different environments. Reindeer are typically found in Arctic regions, while caribou live in the tundra and mountainous areas of North America. Reindeer have a thicker coat of fur to keep them warm in the harsh cold, while caribou have larger hooves and antlers to help them navigate the snowy terrain.
