Photograph by Ami Vitale, National Geographic CreativeConservationists were expecting the death of Sudan, the world's last remaining male northern white rhinoceros. Now, only two female northern white rhinos remain at the conservancy—the last of their kind on Earth. Sex cells were harvested from the living northern white rhinos, and scientists are hoping to use IVF to impregnate southern white rhino surrogates. But when the northern white rhino population began to decline, it was lightning fast. The eastern black rhino, numbering around a thousand, could be the next rhino species facing extinction.
