Rhino Facts Black Rhinos are only one of the 5 species of remaining rhinos. The others are the White Rhino, Sumatran Rhino, Greater One-Horned Rhino and the Javan Rhino, which is the most rare. Rhinos have actually roamed the earth for over 50 million years. Until the early part of this century, hundreds of thousands of rhinos roamed over huge areas of Africa and Asia. But the world's rhinos are endangered not because evolution has caught up with them, but because they have been shot.
Man is the adult rhino's only predator.
The black rhino was once found in suitable habitat over much of Africa south of the Sahara. Fortunately, certain governments and conservation organisations and concerned individuals have, in the past few years, made a concerted effort to rectify this disaster. Kenya's success is based on good protection of fenced-in private and public sanctuaries. The gestation period is between 15 and 16 months. Rhinos have poor vision and are unable to detect a motionless person at a distance of more than 100 feet.
