In a statement, the conservancy said: "It is with great sadness that Ol Pejeta Conservancy and the Dvur Kralove Zoo announce that Sudan, the world's last male northern white rhino, age 45, has died at Ol Pejeta Conservancy in Kenya".
Sudan was being treated for age-related complications that had affected his muscles and bones and also gave him extensive skin wounds.
This is bad news in all other regards but great news if you're in the mood to suddenly feel overwhelming despair at just how much we've fucked up everything on the planet: the last male northern white rhino has died in captivity.
Sudan was listed as "The Most Eligible Bachelor in the World" by Tinder a year ago in partnership with the conservancy, in a campaign to heighten awareness and raise $9 million to save the species.
He had been unwell for some time and passed away on Monday, said the Ol Pejeta Conservancy where he lived in central Kenya.
It stated that Sudan's condition worsened significantly in the last 24 hours and he was unable to stand up as he was suffering a great deal.
His death won't have an impact on the efforts to save the subspecies, as the focus turns to in vitro fertilization techniques using stored semen from other dead rhinos and eggs extracted from the two remaining females. "The veterinary team from the Dver Kralove Zoo, Ol Pejeta and Kenya Wildlife Service made the decision to euthanise him".
Sudan "significantly contributed to survival of his species as he sired two females", the conservancy said. "Additionally, his genetic material was collected yesterday and provides a hope for future attempts at reproduction of northern white rhinos through advanced cellular technologies".
"Sudan was the last northern white rhino that was born in the wild". Decades of rampant poaching have drastically cut numbers of northern white rhinos as their horns can go for up to $50,000 per kilo, making them more valuable than gold or cocaine.
Roughly 20,000 southern white rhinos remain in Africa.
