Northern White Rhinoceros (Ceratotherium simum cottoni) lives in savanna across Central Africa's Congo Basin. Its conservation status is Critically Endangered.
Fascinating facts about the Northern White Rhinoceros
- Only two northern white rhinos remain alive, and both are females, Najin, born in captivity in 1989, and her daughter Fatu, born in 2000. Since 19 March 2018, there are only two known rhinos of this subspecies left, named Najin and Fatu, both of which are female; barring the existence of unknown or misclassified male northern white rhinos elsewhere in Africa, this makes the subspecies functionally extinct. Their tiny number means no natural breeding can occur, forcing scientists to rely on high-tech rescue plans to keep the genome alive.
- Scientists have already created a bank of 38 frozen embryos, a crucial safety net for a species with no living males. As of 2025, there are 38 northern white rhino embryos that have been created by BioRescue. The embryos are cryopreserved in labs in Berlin, Germany and Cremona, Italy. When a suitable surrogate, likely a southern white rhino, is ready, the embryos could be used to attempt to create a living population.
- Genetic studies show the northern and southern white rhinos have been on separate evolutionary tracks for nearly a million years. A study in 2010 suggested the northern white rhinoceros may be an altogether different species, rather than a subspecies of white rhinoceros, in which case its correct scientific name would be Ceratotherium cottoni. According to the study, distinct morphological and genetic differences suggest the northern white rhinoceros and southern white rhinoceros have been separated for at least a million years. A study in 2016 concluded that the two populations diverged between 0.46 and 0.97 million years ago and found their mitochondrial genomes to be 1.8% divergent.
- Intense poaching wiped the wild northern white rhino from hundreds to a handful within a few decades. Poachers reduced their population from 500 to 15 in the 1970s and 1980s. From the early 1990s through mid-2003, the population recovered to more than 32 animals. Since mid-2003, poaching has intensified and further reduced the wild population. These swings illustrate how quickly illegal hunting can erase a species and why constant anti-poaching effort is essential for any chance of recovery.
- White rhinos act as ecosystem engineers; their massive grazing keeps grasslands short enough to stop wildfires. White rhinoceroses are considered as keystone species because they help to increase the biodiversity of grasses and potentially prevent the wildfires. Waldram et al. (2008) reported that the grazing of grasses by white rhinoceroses makes grasses so short, wildfire cannot burn the grasses. Their loss can therefore lead to a 50% drop in short-grass cover, reshaping the whole savanna.

About the Northern White Rhinoceros
In the scorching savannah, the Northern White Rhinoceros roams as a ghostly apparition, its imposing form undulating across the grasslands with a serene, almost ethereal, gait. As one of the most endangered creatures on the planet, this majestic being moves through the world with a quiet dignity, its massive body a testament to a bygone era of unbridled wilderness. With only a handful of individuals remaining, the Northern White Rhinoceros is a poignant reminder of the fragility and beauty of life on Earth.
