Reindeer | The reindeer (also known as the caribou)
is found in large herds in the very north of the world. Reindeer
inhabit both the Arctic Tundra and the North Pole regions which include
parts of North America, Europe and Asia. The reindeers hooves adapt to
the season so in the summer when the tundra is soft and wet, the
reindeers footpads become sponge-like in order to get a bigger surface
area on the damp group. In the winter, the reindeers footpads
shrink and tighten, exposing the rim of the hoof which cuts into the ice
and crusted snow to stop the reindeer from slipping.
The changes to the reindeer
hooves during the winter enables the reindeer to dig down through the
snow to the reindeers favourite food, a lichen known as reindeer moss.
The reindeers coat has two layers of fur, a thick woolly undercoat and a
longer-haired overcoat which consists of hollow, air-filled hairs which
helps to keep the reindeer warm.
The reindeer travels the furthest of any land mammal with these migrations often containing thousands of reindeer. The caribou of North America can run at speeds up to 50 mph and can travel as many as 3,000 miles a year.The
most extensive migrations occur in spring and fall. The largest
reindeer migrations take place in the spring and autumn when the
reindeer are hungry and in search of food.
The reindeer is often an attempted target for the large predators that exist in the Arctic Circle but the reindeer is very fast and moves in enormous groups so the reindeer is not easy to catch. Arctic wolves, polar bears, brown bears, humans and the occasional shark are amongst those animals that hunt the reindeer.
