This week’s story is on a special northern white rhino, named Sudan. Sudan made headlines last year when the Tinder dating app named him the “most eligible bachelor in the world” in a campaign to raise funds to save the subspecies. With three northern white rhinos left in the world, Sudan is the only male. He is his species last hope, except there’s a small catch. Sudan is 45 years old, considered elderly in rhino years. This is a huge scare, raising fears the subspecies is getting closer to extinction. “We don’t think he will last for much longer,” said Elodie A. Sampere, a spokeswoman at the institute where the rhinos are held. Sudan lives at the Ol Pejeta Conservancy in Kenya with two female northern white rhinos — Fatu and Najin. They are the last three northern white rhinos in existence. Even before his illness, Sudan was a crucial part of ensuring the beloved animal do not go extinct. So much so, he was protected from poachers by 24-hour armed guards. Rhinos are targeted by poachers, fueled by the belief in Asia that their horns cure various ailments. Experts say if poaching continues, rhino deaths could surpass births. The western black rhino was declared extinct seven years ago as a result of poaching. All five remaining rhino species worldwide are considered threatened, according to the conservation group Save the Rhino.
