Uakaris are omnivores that typically eat a diet of fruit, leaves, flowers, insects, and small vertebrates. The uakari has a powerful jaw and sharp teeth that allow it to crush hard fruit and to pierce the exoskeletons of insects. The uakari’s diet is relatively low in protein and fat, but high in fiber. This diet allows the uakari to survive on a poor-quality diet, which is important because the uakari lives in an area where food is scarce. The high level of fiber in its diet also helps the uakari to maintain a healthy gut flora, which is important for digestive health.
