What is a "caribou"?

Caribou, also known as reindeer in some regions, are majestic and highly adaptable animals that inhabit the Arctic and subarctic regions of North America, Europe, and Asia. They are known for their distinctive antlers, which are typically larger and more complex in males. Caribou have a unique and complex social structure, with herds that can range from a few individuals to several thousand, and they undertake long-distance migrations in search of food and suitable habitat. They have adapted to thrive in harsh, cold environments, and their large, rounded hooves help them traverse through snow and soft terrain.
