Proboscis monkey

A human might run for cover with this nose, but for the proboscis monkey, the bigger the nose the better! It turns out that nothing turns on a female proboscis monkey more than a big, bulbous schnoz. According to National Geographic, "Scientists think these outsize organs create an echo chamber that amplifies the monkey’s call, impressing females and intimidating rival males."

These curious-looking monkeys are also amazing swimmers, thanks to their webbed feet and hands. They leap from trees into the water, often hitting with a belly flop. They're so talented in the water that they can often swim faster than crocodiles.
