Pictured: Two huge hippopotamus make a splash as they battle for dominance in a river. The competitive tussle lasted up to ten minutes before one of the hippos decided he'd had enough and swam away. The fight was captured by wildlife photographer Nick Dale in the Serengeti National Park in Tanzania, eastern Africa.
