Rhinoceros in Greek means ‘horned nose’.  Today the rhino is still hunted for its horn.  Previously it was believed the horn had medicinal purposes & could stop nose-bleeds & treat fever.  The horn is made of keratin which is the same protein as your hair & fingernails.  Rhinos are heavy – weighing up to 1 ton.  Rhinos have very bad eyesight but an excellent sense of smell & hearing.  They charge when they are startled & can sprint up to 45km/hr!
