I took this photo of Sudan, the last remaining male northern white rhino in existence, several years ago at Ol Pejeta Conservancy in Laikipia, Kenya.  He’s under 24/7 armed guard to protect him from poachers, and his horns have been shortened as an added precaution.  Sudan is getting on in years—he’s 43—and alas, shows little interest in the remaining pair of female northern white rhinos that share his corner of the wildlife sanctuary.

To keep this remarkable subspecies from going extinct, Ol Pejeta is raising funds to aid the development of in vitro fertilization technology that might work with females from the more numerous southern white rhino population.

It’s a race against time, and Tinder, the popular social app for meeting new people, has partnered with Ol Pejeta to introduce Sudan and the plight of the northern white rhino.

Sudan has quite a profile:  “I’m one of a kind….6ft tall and 5,000 lbs, if it matters.”  Swipe right, and Tinder users in 140 countries will be directed to a page from which they can donate.  Sounds like a great match.
