A calf tends to remain with the mother until the next calf is born, usually two years later. Life Span About 40 years in the wild. Did You Know A rhinoceros's horn grows throughout its life. Poachers kill rhinoceroses for their horns, which are ground and used in traditional Chinese medicine. When they are threatened, rhinoceroses sometimes charge toward a distressing scent or sound.
