Elusive new monkey species has a distinctive grunt and bright orange lips

Sightings of colobus congoensis, a black colobus monkey with human-like eyes and pink-and-orange fur ringing its mouth are rare. But this week, scientists announced they have confirmed that the monkey is a distinct, new species. The World's Host Marco Werman speaks with Junior Amboko, a field conservationist at Florida Atlantic University and anthropologist Kate Detwiler who were among the co-authors of a paper announcing the discovery.
