The Rhinoceros, commonoly known as the Rhino, is a large mammal that lives in Africa and southern Asia. They can reach up to over three tonnes in weight and exist entirely on plants.
Unfortunately their horns are prized as a medecine in Asia and groups of Humans hunt the Rhinos illegaly for their horns, which fetch a high price on the asian market. The horns are made of kerotin, the same material that hair and fingernails are made of. One way of preventing this illegal trade is the infusion of a poison, which is safe for the Rhino but toxic to humans, into the horn to kill ticks.
