The northern white rhinoceros (Ceratotherium simum cottoni) is a critically endangered subspecies of the white rhinoceros and one of the rarest mammals on Earth. As of the latest reports in the provided sources, only two known individuals survive, both females living under protection in Kenya, and the subspecies is generally regarded as functionally extinct.
Taxonomy and naming
The northern white rhinoceros is one of two subspecies of the white rhinoceros, the other being the southern white rhinoceros. Its scientific name is Ceratotherium simum cottoni, and it is also called the northern square-lipped rhinoceros.
Range and habitat
Historically, the subspecies occurred across parts of Central and East Africa. Sources describe its former range as spanning areas from Chad and Sudan to the Democratic Republic of the Congo.
Conservation status
The northern white rhinoceros is listed as critically endangered, and some authorities describe it as possibly extinct in the wild. Recent sources state that only two known individuals remain, both females.
Decline and extinction in the wild
The subspecies suffered a severe population collapse due largely to poaching for its horn. The death of the last known male, Sudan, in 2018 left the subspecies functionally extinct in practice.
Conservation efforts
Current conservation work centers on protecting the two remaining animals and attempting assisted reproduction, including in vitro fertilisation and related reproductive technologies.
Key facts
