A caribou is a large animal with four legs, hooves, and big antlers. In Europe and Asia, a caribou is known as a reindeer.
In North America, caribou live in parts of Canada and Alaska, in both tundra and boreal forests. Many caribou migrate long distances, and all of them are herbivores, living to a great degree on a specific type of lichen. The word caribou is originally French Canadian, from the Micmac word kaleboo, "the one who paws," for the way caribou scratch the snow aside to find moss in the winter.
