Old World Monkey

Named after their “Old World” home, Old World monkeys roam Asia, Africa, and a small part of Europe. Baboons, mandrills, macaques, and more than 70 species belong to this diverse group. Their Asian primate cousin, the gibbon, is famous for brachiating through the jungle, living in monogamous family groups, and singing.

Explore these amazing primates and listen to their calls and songs.
