The world's last surviving male northern white rhino is under 24-hour armed guard in Kenya as conservationists make a final effort to save the species. The northern white rhino, known as Sudan, is an elderly animal who has been stripped of his horn to make him less attractive to poachers. Samuel Mutisya from Ol Pejeta Conservancy in Kenya is one of those trying to save the species:
