Proboscis Monkey

 

 

 

 

The Proboscis Monkey AT around the seventh year of its life a strange thing starts happening to the nose of the male proboscis monkey: it changes colour and starts growing longer. The nose might eventually grow to about 7 inches and hang below the mouth like a trunk. Sometimes, the monkey has to hold his nose aside while feeding! The nose development occurs only in the males and the purpose of the long nose has still not been determined.
