"Head flung back as if to howl, the monkey merely yawns. His concealed fangs and red chest say he's on top???at least until a male with bigger teeth or a badder attitude overthrows his regime. But looks deceive. 'Male geladas are just peacocks,' says [biologist Chadden] Hunter. 'There's no question who really runs the show.'"

???From "Kings of the Hill?" November 2002, National Geographic magazine
