Adult rhinoceros have no real predators in the wild, other than humans.
Young rhinos can however fall prey to big cats, crocodiles, wild dogs, and hyenas. International trade in rhinoceros horn has been declared illegal. A proposal by Swaziland to lift the international ban was rejected in October 2016.Domestic sale of rhinoceros horn in South Africa, home of 80% of the remaining rhino population, was banned as of 2009. However, that ban was overturned in a court case in 2017, and South Africa plans to draft regulations for the sale of rhino horn, possibly including export for "non-commercial purposes".
