The Rhinoceros is an amazingly large animal, reaching a weight of more than 1 ton. A rhino is so powerful that it could easily overturn a car by charging at it and butting against it with its head. In fact, that's exactly how it fights other rhinos and enemies. A rhino's hide is as thick as 5 centimeters in some places. However, its brains aren't that large, especially for such a large animal. How many horns does a rhino have? Well, the African and Sumatran rhinoceros have 2 horns. The Javan and Indian rhinoceros only have one horn.
