The latest issue of Zoobooks features Old World Monkeys. But what exactly are they?
First of all, let’s go over the difference between monkeys and apes. Chimps, gorillas, and humans are all examples of apes; langurs and tamarins are types of monkeys. What’s the difference? One good rule of thumb is that most monkeys have tails, while apes don’t. Apes are often larger than monkeys, too. In general, apes rely more on their sense of sight, while monkeys rely more on smell, and apes tend to have broader, shorter noses.
When it comes to Old World Monkeys found in Africa and Asia and the New World Monkeys in the Americas, one difference is in their tails—generally speaking, Old World Monkeys don’t have prehensile tails, but New World Monkeys do. There are also differences in the monkeys’ teeth, and Old World Monkeys have nostrils that face sideways (they face downward in New World Monkeys). See if you can spot some of these differences the next time you see monkeys at the zoo!
