what is the difference between caribou and reindeer

Caribou and reindeer are different species of deer. Caribou are native to North America and have large, flat antlers that they shed in the winter. Reindeer are native to Arctic regions and have branching antlers that they keep all year round. Both species are herbivores and have adapted to their cold environments by growing thick coats of fur and having strong hooves that can withstand the snow and ice.
