A line graph titled "There are just two Northern White rhinos left in the world; both are female" outlines the decline in the estimated population of Northern White rhinos from 1960 to 2021. The vertical axis represents the estimated number of rhinos, ranging from zero to 2,500, while the horizontal axis spans the years from 1960 to 2021. In 1960, the estimated population was approximately 2,230 rhinos. The line sharply declines, indicating a significant drop, with the population reaching about 350 rhinos by 1981. The downward trend continues, with a note indicating that by 2018, only two females named Najin and Fatu remain, following the death of the last male, Sudan. Data sources are listed at the bottom as African and Asian Rhino Specialist Groups (AfRSG), with a Creative Commons attribution notation (CC BY).

The Northern White rhino is on the brink of extinction. In the chart, you can see the collapse of this beautiful animal's population as a result of poaching, habitat loss, and conflict.

Now, only two individuals are left — Najin and her daughter, Fatu. Without males, the subspecies is “functionally extinct” and cannot rebuild its population naturally.

Scientists, though, offer some hope of bringing the rhino back through assisted reproduction. Eggs from Najin and Fatu have been fertilized with preserved sperm from dead male rhinos to produce viable embryos. Since neither Najin nor Fatu can carry a pregnancy, the plan is to use a female Southern White rhino — the closest subspecies — as a surrogate, to carry the embryo through to birth.

In 2023, a surrogate called Curra became pregnant, showing that the method works. Sadly, she died of a bacterial infection during pregnancy.

Scientists plan to try again and are also exploring other breakthrough reproduction treatments to save the Northern White rhino before it’s lost forever.
