Earth’s largest monkey, baboons, have distinct, individually recognizable faces and rumps. The 5 species live in a wide range of habitats, including rainforests, savannas, and coastlines. Leopards and cheetahs prey upon baboons, but, by far, their primary predators are humans. Baboons are omnivores, hence domestic crops can be a part of their diet. Like so many mammals seen as threats to humans and human enterprises, baboons are frequently exterminated. Agricultural expansion, overgrazing of livestock, and increased use in laboratories and medical research have also caused their numbers to decline.
