Sudan, the world's last male northern white rhinoceros, died in Kenya on Monday, leaving his species one step closer to extinction, even as a group of scientists undertake an unprecedented effort to try to keep this animal from vanishing entirely.
Sudan was 45 years old, and his health had deteriorated in recent weeks after a severe leg infection. In a statement, the Ol Pejeta Conservancy said that his condition worsened and that he was no longer able to stand up, so his veterinary team decided to euthanize him.
Sudan was captured in Sudan in 1975, when he was just 2 years old, and was taken to Dvůr Králové Zoo in the Czech Republic. But as that zoo fell into financial troubles and rhinos failed to breed, Sudan was relocated in 2009 to the Ol Pejeta Conservancy, in Laikipia County, Kenya,along with two northern white rhino females named Najin and Fatu.
