Rangifer tarandus

Caribou, also known as reindeer, are majestic animals with large antlers. They roam the cold Arctic regions and are known for their long migrations in search of food.

Habitat: Tundra

Appearance

The Caribou has a dense, shaggy coat, often grayish-brown to nearly white, with a distinct white mane and rump. Their large, crescent-shaped hooves are a key visual feature, helping them traverse diverse terrains. Antlers, often wide and complex, are typically grown by both males and females.

Interesting facts

Caribou calves can run and keep up with the herd within just hours of being born.

Caribou can walk on slippery ice without slipping thanks to their sharp hoof edges.

Their fur has more hairs per square inch than any other deer species on Earth!

They make a unique clicking sound with their knees when they walk, helping the herd stay together.

Special abilities

Caribou have wide, concave hooves that act like snow shovels to dig for food under snow, helping them find lichen.

Caribou can see ultraviolet light, which helps them spot white lichens and predators against the snow.

Caribou possess hollow hairs in their thick coat that trap air, providing excellent insulation against extreme Arctic cold.
