The buffalo did not die immediately and rangers at the reserve think the animal must have been unwell to act so out of character.
The extraordinary scene was captured by amateur photographer Kimberly Maurer, 56, who was on holiday at the game reserve.
The 56-year-old said: ‘I started looking through the images on the back of my camera immediately after the attack and became very excited to discover that I had actually captured the event in detail.
‘This photograph was, no doubt, a once-in-a-lifetime capture for me. As you would imagine, his carcass was a meal for another animal or two.’
