The term 'large monkeys' can be solved by the seven-letter word 'baboons'. Baboons are a type of Old World monkey that are native to Africa and Arabia. They are among the largest of all monkeys, with some species reaching up to 90 pounds in weight. They have long, dog-like snouts and powerful jaws, and their fur is usually olive-brown or gray. Baboons live in large groups and are highly social animals.
