If the uakari (wah-KAHR-ee) of the Amazon river basin were human, you’d hesitate to swipe right. Both sexes come with a seriously receding hairline and a body type best described as “frumpy muppet.” To top it off, their faces are…. Red. Really, really red.
They look like a Minnesota frat boy on his third day in Cancun. And they don’t care what you think of them.
Among the four sub-species of bald uakari, that sun-broiled complexion isn’t a sign someone forgot their sunscreen – it’s an honest signal to others that you are a sexy monkey.
That’s because the color of an individual’s face is actually a direct window into their health.
