Pictured: A large hippopotamus demonstrates the size and power of its jaw as it prepares to fight another. Hippos, which often fight over mating partners and territory, open their wide jaws to assert dominance. The giants can often weigh upwards of 2,000kg (315 stone), and are considered one of the most dangerous animals in Africa. The photos were taken on the Chobe River, in Botswana, by South African wildlife photographer Charl Stols.
