Hippopotamus photographs we take in their natural habitat. They spend most of their time in rivers and lakes in Africa to protect themselves from the heat and sunshine. The males are territorial in water and protect their group. To warn other rivals, they open their mouth widely to show the long curved canines/teeth. That is accompanied by loud noises and splashing the water. Fights between massive male hippos can last quite long, and oh boy, how loud they can be. Overall a hippo is most active at night to go on land to forage for food. It walks up to 10 kilometers / 6 miles to find food. The diet of a hippo is mostly grass, which can eat masses of it. In our hippopotamus photographs portfolio, you can license and purchase photographic prints.
