This unforgettable primate, found in the mangrove forests of Borneo, is the proboscis monkey (Nasalis larvatus)! Also known as the long-nosed monkey, males of this species sport a distinctive drooping proboscis, which acts like a resonating chamber to amplify their vocalizations. Scientists think it’s a sexually selected trait—meaning that females prefer louder (and bigger-nosed) mates.
