In a dense forest with dappled light, it’s nearly impossible to see the elusive okapi! Its broken pattern of dark and light stripes helps it hide from predators. As herbivores, okapi feed on leaves, grasses, ferns, fruits and other understory plants. They use their long blue-black tongues, that can stretch up to 18 inches, to reach and grasp leaves. | Bronx Zoo
