A small heard of zebra stop for a drink on a hot summer’s day. A zebra is singled out by a crocodile and attacked. The zebra starts its battle for survival, a determined crocodile struggles to secure its next meal. After a tiring battle the zebra emerges from the water, tired and subdued. It won the fight for life – this time. These dramatic pictures were taken in the Kruger National Park by wildlife photographer Ed Harris
