The rhinoceros - this giant, eats about 190 to 200 types of plants, of which leaves, little boughs and the bark of a tree. By its curved horn it burrows the ground, thus finding roots and bulbs, which vary its food. Its upper lip has a bump, allowing the animal to catch even the young buds on the trees. It goes out for food in the night, and in daytime it rests. Its incisors are weak, and it has no upper canines.
