Animal Facts
Proboscis monkeys have webbed toes and are good swimmers.
The proboscis monkey is a very vocal species, with group members often calling to each other to bond, relay information or initiate mating.
The large nose of the male proboscis monkey allows it to make louder vocalisations, which in turn increases the likelihood of attracting females.
The proboscis monkey has a ‘pot belly’ due to their stomach acting like that of a ruminants and breaking down tough-to-digest plant matter.
Alpha male proboscis monkeys make alarm calls to warn their group members of nearby danger.
