Fauna of Africa
Fauna of Africa, in its broader sense, is all the animals living in Africa and its surrounding seas and islands. The more characteristic African fauna is found in the Afrotropical ecoregion. Lying almost entirely within the tropics, and equally to north and south of the equator creates favourable conditions for rich wildlife.
