There are more ants than any other kinds of land animals in the world. They range from 0.1 to 1 inch long and are usually yellow, brown, red, or black. Ants live in societies in which they depend on one another. The societies are not all exactly the same because there are ants of very many kinds.

In some parts of the world, red ants march in large armies to attack the homes of black ants. Some of them succeed in getting inside of the tunnels of black ants, whose entrances have been blocked. They try to carry the black ant babies away. The black ants do all they can to prevent that. They send their biggest soldiers into action. Very many of the red ants soldiers are killed but some escape with babies belonging to the black ants. The red ants take the babies home and bring them up.
