The white rhinoceros consists of two subspecies: the southern white rhinoceros, with an estimated 16,803 wild-living animals, [3] and the much rarer northern white rhinoceros. The northern subspecies has very few remaining individuals, with only two confirmed left in 2018 (two females: Fatu, 24 and Najin, 29, both in captivity at Ol Pejeta).
The black rhinoceros can also be distinguished from the white rhinoceros by its size, smaller skull, and ears; and by the position of the head, which is held higher than the white rhinoceros, since the black rhinoceros is a browser and not a grazer.

The rhinoceros then tries an agile headbutt, but the elephant proves better with his seven-foot tusks. Sure enough, the elephant turns his rival around and stabs him twice with his tusks (breaking one in the process that gets stuck in the rhinoceros).
The western black rhino emerged about seven to eight million years ago. It was a sub-species of the black rhino. For much of the 20th century, its population was the highest out of all of the rhino species, at almost 850,000 individuals. There was a 96% population decline in black rhinos, including the western black rhino, between 1970 and 1992.
