His name is Sudan and he is the last known male northern white rhinoceros in the world. Now, international wildlife conservationists are doing everything they can to keep Sudan safe in the hope that he will mate with one of the remaining white rhinos brought to the Ol Pejeta Conservancy in Kenya in 2009.
