The buffalo bull charges, on March 23, 2014, in Addo Elephant National Park, South Africa. A young elephant calf tried to attack an old buffalo bull and was taught a lesson it will never forget. The calf was with its herd at a watering hold Addo Elephant National park, South Africa, when the buffalo ventured towards the water. The elephant ran towards the buffalo but the larger animal picked up the young calf and tossed it four metres in the air. Luckily, the elephant was not hurt, but its pride was seriously injured.
