The reindeer belongs to the cervidae family, and is well known as the animal said to pull Santa’s sleigh. Both male and female reindeer have antlers, the female’s growing in winter and falling off in spring/summer, and the male’s growing in spring and falling off in autumn/winter. They inhabit the cold tundra of the Arctic Circle, feeding on grasses and plants in the summer, and in the winter they use their antlers and hooves to dig through the snow for lichen such as reindeer moss. Reindeer’s bodies feature a thick covering of fur, and large hooves which have developed that way to ensure they can walk on the snow without sinking. They are also known for seasonal large-scale migration that takes place in groups, in search of food.
