what's the difference between reindeer and caribou

Reindeer and caribou are actually the same species, called the caribou in North America and the reindeer in Europe and Asia. They are a type of deer with large antlers and a coat that changes color with the seasons. While they may look similar, there are some differences between the two subspecies. For example, reindeer have a larger body size and heavier antlers than caribou. Additionally, reindeer have adapted to colder climates and are more likely to live in areas with snow and ice. Caribou are more likely to live in forests and tundra areas.
