This image was captured at a waterhole in Etosha National Park where the zebras arrived in a single file line to quench their mid-morning thirst. Suddenly, there was chaos and thick dust clouds blinded our vision. Within moments, two male zebras emerged from the dust, throwing heavy blows at each other with their hooves and heads. The duel only lasted a few minutes but it gave me an opportunity to capture this highly charged moment, among otherwise peaceful animals.
