Kenyans on Twitter were on Tuesday joined by Twitterati all over the world in mourning the death of Sudan, the last male northern white rhino.

Sudan was put down on Monday through euthanasia by a veterinary team from the Dvůr Králové Zoo, Ol Pejeta Conservancy, and the Kenya Wildlife Service(KWS).

‘The Lone Bachelor’ as he was fondly nicknamed, was being treated for age-related complications that led to degenerative changes in muscles and bones combined with extensive skin wounds. He died aged 45.

The Ol Pejeta Conservancy, which looked after Sudan at its base in Kenya, on Tuesday said Sudan’s condition worsened significantly in the last 24 hours as he was unable to stand up and was suffering a great deal.

“Sudan will be remembered for his unusually memorable life. In the 1970s, he escaped extinction of his kind in the wild when he was moved to Dvůr Králové Zoo(Czech Republic.) Throughout his existence, he significantly contributed to survival of his species as he sired two females,” the conservancy eulogised Sudan.

Additionally, his genetic material was collected on Monday and provides a hope for future attempts at a reproduction of northern white rhinos through advanced cellular technologies.

The conservancy said Sudan during his final years came back to Africa and stole the heart of many with his dignity and strength.

“We on Ol Pejeta are all saddened by Sudan’s death. He was a great ambassador for his species and will be remembered for the work he did to raise awareness globally of the plight facing not only rhinos but also the many thousands of other species facing extinction as a result of unsustainable human activity. One day, his demise will hopefully be seen as a seminal moment for conservationists worldwide,” said Richard Vigne, Ol Pejeta’s CEO.

The death of the global icon and gentle giant was felt from all corners of the world as netizens took to social media to fault the human species for letting down Sudan.
