Apes are the closest relatives of humans. Monkeys and apes aren’t belonging to the same species. Monkeys and apes are primates. They live in the tropics, especially in rainforests. Monkeys are smaller than apes; they have long tails which they often use as an extra “hand”. All apes sleep at night. Some of them make platforms in the trees; others make nests on the ground. Apes mostly eat plants and sometimes kill small animals, like insects, for food. Apes live 30 years or more. Apes are very clever animals, second only to humans.
