(CNN) - Unique? Suni was much more than that. He was vital to the survival of his kind.
The 34-year-old northern white rhino was found dead in his enclosure (Kenya wildlife conservancy) on October 17, 2014. Rangers are unsure of the cause of his death, but said that he was not killed by poachers.
Suni was one of only seven northern whites left in the world, all of which live in captivity. There are none known to be left in the wild.
More importantly, Suni was one of only two breeding males left, said the Ol Pejeta Conservancy in a statement.
Now the conservationists have but one male and two females that can breed. And that doesn't happen often. When Suni mated with female Najin in April 2012, it was her first time in ten years.
A month passed before they mated again. So far, no offspring. (read more ...)
