Conservation enthusiasts on Tuesday morning woke up the sad news of the death of Sudan, the last male northern white rhino.
Sudan was a no ordinary rhino as he was was some kind of a 'celeb' who stole the hearts of many who came to Kenya to see him and even posed for photos with him.
He was the last male northern white rhino and last hope for the breed in the world.
Sudan was born in Northern Sudan in November 19, 1973 and died on Tuesday, March 20 in Kenya after a long battle with age-related complications.
The 45-year-old rhino is reported to have been euthanised on Monday after his condition "worsened significantly". He was no longer able to stand.
"His muscles and bones had degenerated and his skin had extensive wounds, with a deep infection on his back right leg, " read a statement from Ol Pejeta Conservancy in Kenya.
Sudan was just a baby when he was captured by a team from the Chipperfield safari park firm in Shambe game reserve, South Sudan, in February 1975.
He was then guarded by a police officer 24 hours to protect him from poaching.
Sudan was later moved to Ol Pejeta Conservancy for a "Last Chance To Survive" breeding program in December 2009 with three fertile surviving females.
This was in the hope that he would provide a more natural habitat for the animals to induce breeding.
In April 2017, Sudan joined Tinder in search of a hook-up mate as conservationists struggled to save his species.
At the time, he had been dubbed as "the most eligible bachelor in the world" by the zoo team that was caring for him.
Tinder made him a profile which was available all over the world and was broadcast in 190 countries and in 40 languages.
UK and Europe made their donations which were processed by Virgin Money, in the US by CrowdRise and in Kenya by popular mobile service MPesa.
Sudan fathered three babies with a female named Nasima, but after she died. He then refused to mate with the other females, charging and injuring them with his huge horn.
The only hope for preserving the subspecies now lies in developing in-vitro fertilisation techniques using eggs from the two remaining females, stored northern white rhino semen from males and surrogate southern white rhino females.
KOT 'mourned' him in a series of tweets.
