From the Telegraph:
A series of incredible pictures taken at a South African game reserve document the first known time that a leopard has taken on and defeated one of the fearsome reptiles.
The photographs were taken by Hal Brindley, an American wildlife photographer, who was supposed to be taking pictures of hippos from his car in the Kruger National Park.
The giant cat raced out of cover provided by scrub and bushes to surprise the crocodile, which was swimming nearby.
A terrible and bloody struggle ensued. Eventually, onlookers were amazed to see the leopard drag the crocodile from the water as the reptile fought back.
