A hand skims the glassy waters of the Okavango Delta in Botswana, an area that is home to many animals including African bush elephant, African buffalo, hippopotamus, blue wildebeest, giraffe, Nile crocodile, lion, cheetah, leopard, brown hyena, and many others. The Okavango is a very large inland delta formed where the Okavango River reaches a tectonic trough in the central part of the endorheic basin of the Kalahari. The water reaching the Delta does not flow into any sea or ocean.
