Rhinoceros (2007)

With NATURE’S Rhinoceros, wildlife filmmaker Nigel Marven brings you face-to-face with the world’s five species of rhino, each struggling, with varying degrees of success, for their continued survival. For some rhinos, the future may rely on breeding programs, such as at the Cincinnati Zoo & Botanical Gardens, where Sumatran rhinoceros Emi is now nearing the end of her third successful pregnancy, having already given birth to Andalas and Suci, the only two Sumatran rhinos ever to be born in captivity.
