As measured by its huge mass of water the Congo is the second largest river in the world, surrounded by tropical rain forest and fed by countless tributaries in an enormous watershed area in the heart of Africa. The locals call it the river that swallows rivers. As a small trickle in the north of Zambia begins its journey to the west over rapids and waterfalls until it finally pours as 40 km wide estuary into the Atlantic Ocean. Evolution and extreme conditions have created unique beings here. Fishes with lungs, wings or those that go hunting on land. The strange shoebill lurks in the vastness of the papyrus marsh, swarms of fruit bats darken the sky, meter-long pythons hunt in trees, chimpanzees populate the forests and hippopotamus bulls fight for power in the water. Exceptional shots provide insights into one of the most mysterious and dangerous regions of our planet.
