Health of world's last male northern white rhino in decline

JOHANNESBURG — The health of the world’s last male northern white rhino has deteriorated, bringing the rhino subspecies a step closer to extinction caused by poaching.

The 45-year-old rhino named Sudan, listed as “The Most Eligible Bachelor in the World” on the Tinder dating app last year as a fundraiser, lives with the last two female northern white rhinos. Kenya’s Ol Pejeta Conservancy said Thursday that Sudan was struggling despite 24-hour care by veterinarians.

Sudan appeared to recover well from an infection that developed on his back right leg at the end of 2017 but another, deeper infection was recently discovered in the same area, the conservancy said.

“We are very concerned about him — he’s extremely old for a rhino and we do not want him to suffer unnecessarily,” the conservancy said in a statement.

Sudan and the females Najin and Fatu, along with a second male from the same subspecies that since died, arrived at Ol Pejeta from a Czech zoo in 2009.

Scientists hope to save the northern white rhino from extinction by using southern white rhinos as surrogates to carry northern white rhino embryos and give birth. The in vitro process would be conducted using sperm from dead rhinos that is stored in Berlin and eggs extracted by surgery from the females at Ol Pejeta, according to the conservancy.

Northern white rhinos once roamed parts of Chad, Sudan, Uganda, Congo and Central African Republic, and there were more than 2,000 remaining as recently as 1960, according to Save the Rhino International, a London-based group.

There are roughly 20,000 southern white rhinos in Africa after efforts to save them from extinction began in the 1950s.

African rhinos remain under intense pressure from poachers who kill them to meet demand for their horns in illegal markets, primarily in Vietnam and China.
