The poaching and hunting of white rhinos has left just five in the world and only one male.
The last surviving male, named Sudan, is currently housed in Ol Pejeta Conservancy in Kenya and is under 24/7 armed guard protection. He has also had his horns removed to deter poachers and has had radio transmitters attached to him.
Two other female white rhinos are being housed with Sudan.
The only other white rhino on Earth died last year of natural causes. One year ago there were seven white rhinos and in 1960 there were over 2,000.
