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.

This page was imported from Our World in Data. “Only two Northern White rhinos remain, and both are female” by Hannah Ritchie, published by Our World in Data under CC BY 4.0. Changed here: set as a page, its interactive charts shown as pictures. Data from third parties keeps its own licence.
Nobody has written it yet — it is the source material at a new address, which is why search engines are asked to skip it and why no one earns from it. It is up for grabs: take it on, and it is yours to rewrite and to earn from.
