The Proboscis monkey, native to the Southeast Asian island of Borneo, is known for its humongous schnoz, which it uses to attract females. The nose also serves as a resonating chamber that amplifies the monkeys' warning calls.
The proboscis monkey spends most of its time in trees, but it is also an excellent swimmer, having been picked up by fishing boats in open ocean up to a mile from shore. Troops of proboscis monkeys have been filmed walking upright, making the only monkey known to walk on two legs for significant lengths of time.
In addition to its huge nose, this monkey is also known for its pot belly, leading locals to refer to it as the "Dutch Monkey," remarking that their colonizers from the Netherlands often had similarly large noses and bellies.
Only about 1,000 proboscis monkeys are known to still exist in the wild.
