The species is IUCN Red Listed as vulnerable, as it suffered a substantial decline in its historic range in the 20th century due to habitat loss, poaching, illegal pet trade, and conflict with humans. By 2016, the global cheetah population has been estimated at approximately 7,100 individuals in the wild. Several African countries have taken steps to improve cheetah conservation measures. It is the fastest land animal. The only extant member of the genus Acinonyx, the cheetah was formally described by Johann Christian Daniel von Schreber in 1775. The cheetah is characterised by a slender body, deep chest, spotted coat, small rounded head, black tear-like streaks on the face, long thin legs and long spotted tail. Its lightly built, slender form is in sharp contrast with the robust build of the big cats, making it more similar to the cougar. The cheetah reaches nearly at the shoulder, and weighs. Though taller than the leopard, it is notably smaller than the lion. Typically yellowish tan or rufous to greyish white, the coat is uniformly covered with nearly 2,000 solid black spots. Cheetahs are active mainly during the day, with hunting their major activity. Adult males are sociable despite their territoriality, forming groups called coalitions. Females are not territorial; they may be solitary or live with their offspring in home ranges. Carnivores, cheetah mainly prey upon antelopes and gazelles. They will stalk their prey to within, charge towards it and kill it by tripping it during the chase and biting its throat to suffocate it to death. Cheetahs can reach speeds of in short bursts, but this is disputed by more recent measurements. The average speed of cheetahs is about. Cheetahs are induced ovulators, breeding throughout the year. Gestation is nearly three months long, resulting in a litter of typically three to five cubs (the number can vary from one to eight). Weaning occurs at six months; siblings tend to stay together for some time. Cheetah cubs face higher mortality than most other mammals, especially in the Serengeti region. Cheetahs inhabit a variety of habitatsdry forests, scrub forests and savannahs. Because of its prowess at hunting, the cheetah was tamed and used to kill game at hunts in the past. The animal has been widely depicted in art, literature, advertising and animation.
