The Nile crocodile is presently the most common crocodilian in Africa, and is distributed throughout much of the continent. Among crocodilians today, only the saltwater crocodile occurs over a broader geographic area, although other species, especially the spectacled caiman ("Caiman crocodilus") (due to its small size and extreme adaptability in habitat and flexibility in diet), seem to actually be more abundant. This species’ historic range, however, was even wider. They were found as far north as the Mediterranean coast in the Nile Delta and across the Red Sea in Palestine and Syria. The Nile crocodile has historically been recorded in areas where they are now regionally extinct. For example, Herodotus recorded the species inhabiting Lake Moeris in Egypt. They are thought to have become extinct in the Seychelles in the early 19th century (1810–1820). Today, Nile crocodiles are widely found in, among others, Somalia, Ethiopia, Uganda, Kenya, Egypt, the Central African Republic, the Democratic Republic of the Congo, Equatorial Guinea, Tanzania, Rwanda, Burundi, Zambia, Zimbabwe, Gabon, Angola, South Africa, Malawi, Mozambique, Namibia, Sudan, South Sudan, Botswana, and Cameroon. The Nile crocodile's current range of distribution extends from the regional tributaries of the Nile in Sudan and Lake Nasser in Egypt to the Cunene of Angola, the Okavango Delta of Botswana, and the Olifants River in South Africa.
