The Rangifer Tarandus, better known as caribou or reindeer, is an herbivorous species living in the tundra. Tundras have a vastly cold climate, with limited vegetation. Caribou are similar to deer; however they are much bigger with a shoulder standing height of 2.8-4.9 feet, and females weigh 175 to 225 pounds, while males weigh about 350 to 400 pounds (Caribou).
