The Ankole-Watusi, also known as Ankole longhorn, is a breed of cattle originally native to Africa. Its large, distinctive horns, that can reach up to 8 feet (2.4 m) from tip to tip, are used for defense and cooling by blood vesseled honeycombs. Ankole-Watusis weigh from 900 to 1,600 pounds (410 to 730 kg).
