Under 24X7 armed guard: Last surviving male white rhino

White rhinos have been living on this planet for as long as 50 million years. Today, however, only five of these animals remain — of which only one is a male named Sudan. The 40-year-old male rhino lives at Ol Pejeta Nature Conservancy, Kenya, and is on a 24X7 armed guard. He is fitted with a radio transmitter and his position is tracked round the clock by a team of specially trained guards. As a precautionary step, the officials have also removed his horn to make him less attractive to poachers.
