Its advanced rapid hunting technique forces the cheetah only to hunt prey that only it can catch. Its physique does not make it powerful enough to attack larger prey. It is thus ultra-specialised. Like all specialised animals, it is incapable of adapting fast enough to changes in its environment caused by Man and is thus one of the first to be affected. In 2019, only 7,100 individuals were counted, compared with 100,000 at the start of the 20th century.
