The species once roamed most of Africa and parts of Asia and Europe. But African lions have disappeared from 94 percent  of its historic range and can only be found today in parts of sub-Saharan Africa. These lions mainly stick to the grasslands, scrub, or open woodlands where they can more easily hunt their prey, but they can live in most habitats aside from tropical rain forest and deserts.
