At a height of more than 1.8 meters and weighing in at more than a ton, bison are trully powerful mammals with curved horns. Bison live in the prairie and feed on different types of plants. The fact that they are herbivores makes no difference to their temper. Bison are known for their aggressiveness and despite their size are surprisingly agile. Bison graze mornings and evenings and doze during the day. Just like rhinos they enjoy rolling in dust or mud. Bisons live together in herds, looking out for wolves and defending the cows and calves against approaching enemies.
