The need to preserve the northern white rhino is dire -- there are no known animals left in the wild. The northern white rhino cannot mate with a black rhino, but there is a chance it could mate with a southern white rhino, Paul said. While southern white rhinos are not endangered -- Ol Pejeta has 19 -- they are a different subspecies from the northern white rhino genetically. Though the offspring would not be 100% northern white rhino, it would be better than nothing, experts say. Suni, the other male northern white rhino at the conservancy, died last year.
