Also known as the greater one-horned rhinos,  the Indian Rhinoceros inhabit northern India and Nepal. The Indian Rhinoceros have one horn, what makes them different from their African mates, who all have two horns. Rhinoceroses have poor eye sight. However, they make up for it with their exceptional hearing and sense of smell. They are huge animals: the largest individuals weighted up to 4000 kg. Despite of it they are considered to be a good swimmers. Also, they can run at speeds up to 25 miles per hour for short periods. Traditionally, rhinoceroses have been killed for their horns because some Asian cultures believe the horns have medicinal value. But in fact, there is no evidence to prove that rhino horns, which are largely made of keratin (like our hair and fingernails), have any medicinal value at all. Also people were hunting them for sport.
