Noses- Most Old World monkeys have small curved nostrils set close together. Most New World monkeys have round nostrils set far apart.
Cheeks- Macaques and some of the other Old World monkeys have cheek pouches, where food is stuffed on the run so it can be chewed later. New World monkeys don’t have cheek pouches.
Butt padding- Some Old World monkeys, such as drills, have sitting pads on their rumps, but New World monkeys do not.
Tails- Some New World monkeys, such as spider monkeys, have prehensile tails, but Old World monkeys do not. And one Old World monkey species , the Barbary macaque, has no tail at all.
