Does a Black rhino need a specific type of food?

Black (or Hook-lipped) Rhinoceros (Diceros bicornis) do not need specific types of food, although they do graze on certain types of plants. The black rhino has a curved or hooked lip, in order to be able to strip leaves off the branches of small shrubs or lower branches of trees. The white rhino on the other hand, has a flat lip, because it grazes on the ground, eating mainly grass.
