About

The proboscis monkey or long-nosed monkey is an arboreal Old World monkey with an unusually large nose, a reddish-brown skin color and a long tail. It is endemic to the Southeast Asian island of Borneo and is found mostly in mangrove forests and on the coastal areas of the island.

Fun Fact

Proboscis monkeys' enormous noses amplify their calls and may signal fitness to females — the bigger the nose, the louder the honk, and dominant males have the largest noses.
