Hippopotamus
Many hippos lived in North Africa and Europe until about 30,000 years ago. They used to be common in Egypt's Nile region from long ago, though they are not there now. Pliny the Elder writes that, in his time, the best place in Egypt for finding this animal was in Sais. The animal could still be found around there after the Arab Conquest in 639. Hippos are still found in the rivers and lakes of: Uganda, Sudan, Somalia, Kenya, northern Democratic Republic of the Congo and Ethiopia, west through Ghana to Gambia and also in Southern Africa (Botswana, Republic of South Africa, Zimbabwe, Zambia). Some hippos also live in Tanzania and Mozambique. They like to live in places with water that is not too deep.
