Thecheetah(Acinonyx jubatus) is a largecatand thefastestland animal. It has a tawny to creamy white or pale buff fur that is marked with evenly spaced, solid black spots. The head is small and rounded, with a shortsnoutand black tear-like facial streaks. It reaches 67–94 cm (26–37 in) at the shoulder, and the head-and-body length is between 1.1 and 1.5 m (3 ft 7 in and 4 ft 11 in). Adults weigh between 21 and 72 kg (46 and 159 lb). The cheetah is capable of running at 93 to 104 km/h (58 to 65 mph); it has evolved specialized adaptations for speed, including a light build, long thin legs and a long tail.

The cheetah was firstdescribedin the late 18th century. Four subspecies are recognised today that are native toAfricaand centralIran.An African subspecies wasintroduced to Indiain 2022. It is now distributed mainly in small, fragmented populations in northwestern,easternandsouthern Africaand central Iran. It lives in a variety of habitats such assavannahsin theSerengeti,arid mountain ranges in theSahara,and hilly desert terrain.

The cheetah lives in three mainsocial groups:females and their cubs, male "coalitions", and solitary males. While females lead a nomadic life searching for prey in largehome ranges,males are more sedentary and instead establish much smallerterritoriesin areas with plentiful prey and access to females. The cheetah is active during the day, with peaks during dawn and dusk. It feeds on small- to medium-sized prey, mostly weighing under 40 kg (88 lb), and prefers medium-sizedungulatessuch asimpala,springbokandThomson's gazelles.The cheetah typically stalks its prey within 60–100 m (200–330 ft) before charging towards it, trips it during the chase and bites its throat to suffocate it to death. It breeds throughout the year. After agestationof nearly three months, females give birth to a litter of three or four cubs. Cheetah cubs are highly vulnerable to predation by other large carnivores. They are weaned at around four months and are independent by around 20 months of age.

The cheetah is threatened byhabitat loss,conflict with humans,poachingand high susceptibility to diseases. The global cheetah population was estimated in 2021 at 6,517; it is listed asVulnerableon theIUCN Red List.It has been widely depicted in art, literature, advertising, and animation. It wastamedinancient Egyptand trained for hunting ungulates in theArabian Peninsulaand India. It has been kept inzoossince the early 19th century.

Etymology

The vernacular name "cheetah" is derived fromHindustaniUrdu:چیتاandHindi:चीता(ćītā).[3]This in turn comes fromSanskrit:चित्रय(Chitra-ya) meaning 'variegated', 'adorned' or 'painted'.[4]In the past, the cheetah was often called "hunting leopard" because they could be tamed and used forcoursing.[5]Thegeneric nameAcinonyxprobably derives from the combination of twoGreekwords:ἁκινητος(akinitos) meaning 'unmoved' or 'motionless', andὄνυξ(onyx) meaning 'nail' or 'hoof'.[6]A rough translation is "immobile nails", a reference to the cheetah's limited ability to retract its claws.[7]A similar meaning can be obtained by the combination of the Greek prefixa–(implying a lack of) andκῑνέω(kīnéō) meaning 'to move' or 'to set in motion'.[8]Thespecific namejubatusisLatinfor 'crested, having a mane'.[9]

A few old generic names such asCynailurusandCynofelisallude to the similarities between the cheetah andcanids.[10]

In 1777,Johann Christian Daniel von Schreberdescribed the cheetah based on a skin from theCape of Good Hopeand gave it thescientific nameFelis jubatus.[11]Joshua Brookesproposed thegenericnameAcinonyxin 1828.[12]In 1917,Reginald Innes Pocockplaced the cheetah in a subfamily of its own, Acinonychinae,[13]given its striking morphological resemblance to thegreyhoundand significant deviation from typical felid features; the cheetah was classified inFelinaein later taxonomic revisions.[14]

In the 19th and 20th centuries, several cheetahspecimenswere described; some were proposed assubspecies.An example is the South African specimen known as the "woolly cheetah", named for its notably dense fur—this was described as a new species (Felis lanea) byPhilip Sclaterin 1877,[15]but the classification was mostly disputed.[16]There has been considerable confusion in the nomenclature of cheetahs andleopards(Panthera pardus) as authors often confused the two; some considered "hunting leopards" an independent species, or equal to the leopard.[17][18]

Subspecies

In 1975, five cheetah subspecies were consideredvalidtaxa:A. j. hecki,A. j. jubatus,A. j. raineyi,A. j. soemmeringiiandA. j. venaticus.[19]In 2011, aphylogeographicstudy found minimalgenetic variationbetweenA. j. jubatusandA. j. raineyi;only four subspecies were identified.[20]In 2017, the Cat Classification Task Force of theIUCNCat Specialist Group revised felid taxonomy and recognised these four subspecies as valid. Their details are tabulated below:[19][21]

The cheetah's closest relatives are thecougar(Puma concolor) and thejaguarundi(Herpailurus yagouaroundi).[19]Together, these three species form thePumalineage, one of the eight lineages of the extantfelids;thePumalineagedivergedfrom the rest 6.7mya.Thesister groupof thePumalineage is acladeof smallerOld Worldcats that includes the generaFelis,OtocolobusandPrionailurus.[30]

The oldest cheetah fossils, excavated in eastern and southern Africa, date to 3.5–3 mya; the earliest known specimen from South Africa is from the lowermost deposits of the Silberberg Grotto (Sterkfontein).[2][8]Though incomplete, these fossils indicate forms larger but lesscursorialthan the modern cheetah.[31]The first occurrence of the modern speciesA. jubatusin Africa may come from Cooper's D, a site in South Africa dating back to 1.5 to 1.4 Ma, during theCalabrianstage.[32]Fossil remains from Europe are limited to a fewMiddle Pleistocenespecimens fromHundsheim(Austria) and Mosbach Sands (Germany).[33]Cheetah-like cats are known from as late as 10,000 years ago from the Old World. Thegiant cheetah(A. pardinensis), significantly larger and slower compared to the modern cheetah, occurred in Eurasia and eastern and southern Africa in theVillafranchianperiod roughly 3.8–1.9 mya.[14][34]In the Middle Pleistocene a smaller cheetah,A. intermedius,ranged from Europe to China.[2]The modern cheetah appeared in Africa around 1.9 mya; its fossil record is restricted to Africa.[31]

Extinct North American cheetah-like cats had historically been classified inFelis,PumaorAcinonyx;two such species,F. studeriandF. trumani,were considered to be closer to the puma than the cheetah, despite their close similarities to the latter. Noting this, palaeontologist Daniel Adams proposedMiracinonyx,a new subgenus underAcinonyx,in 1979 for the North American cheetah-like cats;[35]this was later elevated to genus rank.[36]Adams pointed out that North American and Old World cheetah-like cats may have had a common ancestor, andAcinonyxmight have originated in North America instead of Eurasia.[35]However, subsequent research has shown thatMiracinonyxis phylogenetically closer to the cougar than the cheetah;[37]the similarities to cheetahs have been attributed toparallel evolution.[30]

The three species of thePumalineage may have had a common ancestor during theMiocene(roughly 8.25 mya).[35][38]Some suggest that North American cheetahs possibly migrated to Asia via theBering Strait,then dispersed southward to Africa through Eurasia at least 100,000 years ago;[39][40][41]some authors have expressed doubt over the occurrence of cheetah-like cats in North America, and instead suppose the modern cheetah to have evolved from Asian populations that eventually spread to Africa.[37][42]The cheetah is thought to have experienced twopopulation bottlenecksthat greatly decreased thegenetic variabilityin populations; one occurred about 100,000 years ago that has been correlated to migration from North America to Asia, and the second 10,000–12,000 years ago in Africa, possibly as part of theLate Pleistocene extinction event.[40][43][44]

Genetics

Thediploidnumber ofchromosomesin the cheetah is 38, the same as in most other felids.[45]The cheetah was the first felid observed to have unusually low genetic variability among individuals,[46]which has led to poor breeding in captivity, increasedspermatozoaldefects, high juvenile mortality and increased susceptibility to diseases and infections.[47][48]A prominent instance was the deadlyfeline coronavirusoutbreak in a cheetah breeding facility of Oregon in 1983 which had a mortality rate of 60%, higher than that recorded for previousepizooticsoffeline infectious peritonitisin any felid.[49]The remarkable homogeneity in cheetah genes has been demonstrated by experiments involving themajor histocompatibility complex(MHC); unless the MHC genes are highly homogeneous in a population,skin graftsexchanged between a pair of unrelated individuals would be rejected. Skin grafts exchanged between unrelated cheetahs are accepted well and heal, as if their genetic makeup were the same.[50][51]

The low genetic diversity is thought to have been created by twopopulation bottlenecksfrom about 100,000 years and about 12,000 years ago, respectively. The resultant level of genetic variation is around 0.1–4% of average living species, lower than that ofTasmanian devils,Virunga gorillas,Amur tigers,and even highly inbred domestic cats and dogs.[48]

King cheetah

The king cheetah is a variety of cheetah with a raremutationfor cream-coloured fur marked with large, blotchy spots and three dark, wide stripes extending from the neck to the tail.[52]InManicaland,Zimbabwe,it was known asnsuifisiand thought to be acrossbetween a leopard and ahyena.[53]In 1926, Major A. Cooper wrote about a cheetah-like animal he had shot near modern-dayHarare,with fur as thick as that of asnow leopardand spots that merged to form stripes. He suggested it could be a cross between a leopard and a cheetah. As more such individuals were observed it was seen that they had non-retractable claws like the cheetah.[54][55]

In 1927, Pocock described these individuals as a new species by the name ofAcinonyx rex( "king cheetah" ).[54]However, in the absence of proof to support his claim, he withdrew his proposal in 1939.Abel Chapmanconsidered it acolour morphof the normally spotted cheetah.[56]Since 1927, the king cheetah has been reported five more times in the wild in Zimbabwe, Botswana and northernTransvaal;one was photographed in 1975.[53]

In 1981, two female cheetahs that had mated with a wild male from Transvaal at theDe Wildt Cheetah and Wildlife Centre(South Africa) gave birth to one king cheetah each; subsequently, more king cheetahs were born at the centre.[56]In 2012, the cause of this coat pattern was found to be a mutation in the gene fortransmembraneaminopeptidase(Taqpep), the same gene responsible for the striped "mackerel" versus blotchy "classic" pattern seen intabby cats.[57]The appearance is caused by reinforcement of arecessive allele;hence if two mating cheetahs areheterozygouscarriersof the mutated allele, a quarter of their offspring can be expected to be king cheetahs.[58]

The cheetah is a lightly built, spotted cat characterised by a small rounded head, a shortsnout,black tear-like facial streaks, a deep chest, long thin legs and a long tail. Its slender, canine-like form is highly adapted for speed, and contrasts sharply with the robust build of the genusPanthera.[10][59]Cheetahs typically reach 67–94 cm (26–37 in) at the shoulder and the head-and-body length is between 1.1 and 1.5 m (3 ft 7 in and 4 ft 11 in).[8][60][61]The weight can vary with age, health, location, sex and subspecies; adults typically range between 21 and 72 kg (46 and 159 lb). Cubs born in the wild weigh 150–300 g (5.3–10.6 oz) at birth, while those born in captivity tend to be larger and weigh around 500 g (18 oz).[10][58][60]Cheetahs aresexually dimorphic,with males larger and heavier than females, but not to the extent seen in other large cats.[61][62][63]Studies differ significantly on morphological variations among the subspecies.[62]

The coat is typically tawny to creamy white or pale buff (darker in the mid-back portion).[8][60]The chin, throat and underparts of the legs and the belly are white and devoid of markings. The rest of the body is covered with around 2,000 evenly spaced, oval or round solid black spots, each measuring roughly 3–5 cm (1.2–2.0 in).[58][64][65]Each cheetah has a distinct pattern of spots which can be used to identify unique individuals.[61]Besides the clearly visible spots, there are other faint, irregular black marks on the coat.[64]Newly born cubs are covered in fur with an unclear pattern of spots that gives them a dark appearance—pale white above and nearly black on the underside.[10]The hair is mostly short and often coarse, but the chest and the belly are covered in soft fur; the fur of king cheetahs has been reported to be silky.[8][66]There is a short, rough mane, covering at least 8 cm (3.1 in) along the neck and the shoulders; this feature is more prominent in males. The mane starts out as a cape of long, loose blue to grey hair in juveniles.[58][66]Melanisticcheetahs are rare and have been seen in Zambia and Zimbabwe.[64]In 1877–1878, Sclater described two partiallyalbinospecimens from South Africa.[58]

The head is small and more rounded compared to otherbig cats.[67]Saharan cheetahs have canine-like slim faces.[64]The ears are small, short and rounded; they are tawny at the base and on the edges and marked with black patches on the back. The eyes are set high and have roundpupils.[61]The whiskers, shorter and fewer than those of other felids, are fine and inconspicuous.[68]The pronounced tear streaks (or malar stripes), unique to the cheetah, originate from the corners of the eyes and run down the nose to the mouth. The role of these streaks is not well understood—they may protect the eyes from the sun's glare (a helpful feature as the cheetah hunts mainly during the day), or they could be used to define facial expressions.[64]The exceptionally long and muscular tail, with a bushy white tuft at the end, measures 60–80 cm (24–31 in).[69]While the first two-thirds of the tail are covered in spots, the final third is marked with four to six dark rings or stripes.[58][65]

The cheetah is superficially similar to the leopard, which has a larger head, fully retractable claws,rosettesinstead of spots, lacks tear streaks and is more muscular.[63][70]Moreover, the cheetah is taller than the leopard. Theservalalso resembles the cheetah in physical build, but is significantly smaller, has a shorter tail and its spots fuse to form stripes on the back.[71]The cheetah appears to have evolved convergently with canids in morphology and behaviour; it has canine-like features such as a relatively long snout, long legs, a deep chest, tough paw pads and blunt, semi-retractable claws.[72][73]The cheetah has often been likened to the greyhound, as both have similar morphology and the ability to reach tremendous speeds in a shorter time than other mammals,[66][69]but the cheetah can attain much higher maximum speeds.[74]

Sharply contrasting with the other big cats in its morphology, the cheetah shows several specialized adaptations for prolonged chases to catch prey at some of the fastest speeds reached by land animals.[75]Its light, streamlined body makes it well-suited to short, explosive bursts of speed, rapid acceleration, and an ability to execute extreme changes in direction while moving at high speed.[76][77][78]The largenasal passages,accommodated well due to the smaller size of the canine teeth, ensure fast flow of sufficient air, and the enlarged heart and lungs allow the enrichment of blood with oxygen in a short time. This allows cheetahs to rapidly regain their stamina after a chase.[2]During a typical chase, theirrespiratory rateincreases from 60 to 150 breaths per minute.[79]Moreover, the reducedviscosityof the blood at higher temperatures (common in frequently moving muscles) could ease blood flow and increaseoxygen transport.[80]While running, in addition to having good traction due to their semi-retractable claws, cheetahs use their tail as a rudder-like means of steering that enables them to make sharp turns, necessary to outflank antelopes which often change direction to escape during a chase.[58][67]The protracted claws increase grip over the ground, while rough paw pads make the sprint more convenient over tough ground. The limbs of the cheetah are longer than what is typical for other cats its size; the thigh muscles are large, and thetibiaandfibulaare held close together making the lower legs less likely to rotate. This reduces the risk of losing balance during runs, but compromises the cat's ability to climb trees. The highly reducedclavicleis connected throughligamentsto thescapula,whose pendulum-like motion increases the stride length and assists in shock absorption. The extension of thevertebral columncan add as much as 76 cm (30 in) to the stride length.[81][82]

The cheetah resembles the smaller cats incranialfeatures, and in having a long and flexible spine, as opposed to the stiff and short one in other large felids.[2]The roughly triangular skull has light, narrow bones and thesagittal crestis poorly developed, possibly to reduce weight and enhance speed. The mouth can not be opened as widely as in other cats given the shorter length of muscles between the jaw and the skull.[58][63]A study suggested that the limited retraction of the cheetah's claws may result from the earlier truncation of the development of the middlephalanx bonein cheetahs.[75]

The cheetah has a total of 30 teeth; thedental formulais3.1.3.13.1.2.1.The sharp, narrowcarnassial molarsare larger than those of leopards andlions,suggesting the cheetah can consume a larger amount of food in a given time period. The small, flatcaninesare used to bite the throat and suffocate the prey. A study gave thebite force quotient(BFQ) of the cheetah as 119, close to that for the lion (112), suggesting that adaptations for a lighter skull may not have reduced the power of the cheetah's bite.[2][10]Unlike other cats, the cheetah's canines have no gap behind them when the jaws close, as the top and bottom cheek teeth show extensive overlap; this equips the upper and lower teeth to effectively tear through the meat. The slightly curved claws, shorter and straighter than those of other cats, lack a protective sheath and are partly retractable.[58][61]The claws are blunt due to lack of protection,[64]but the large and strongly curveddewclawis remarkably sharp.[83]Cheetahs have a high concentration ofnerve cellsarranged in a band in the centre of the eyes, a visual streak, the most efficient among felids. This significantly sharpens the vision and enables the cheetah to swiftly locate prey against the horizon.[59][84]The cheetah is unable to roar due to the presence of a sharp-edged vocal fold within thelarynx.[2][85]

Speed and acceleration

Documentary videofilmed at 1200 frames per second showing the movement ofSarah,the fastest recorded cheetah, over a set run

The cheetah is the world'sfastestland animal.[86][87][88][89][90]Estimates of the maximum speed attained range from 80 to 128 km/h (50 to 80 mph).[58][61]A commonly quoted value is 112 km/h (70 mph), recorded in 1957, but this measurement is disputed.[91]In 2012, an 11-year-old cheetah from theCincinnati Zooset a world record by running 100 m (330 ft) in 5.95 seconds over a set run, recording a maximum speed of 98 km/h (61 mph).[92]

Cheetahs equipped withGPS collarshunted at speeds during most of the chase much lower than the highest recorded speed; their run was interspersed with a few short bursts of a few seconds when they attained peak speeds. The average speed recorded during the high speed phase was 53.64 km/h (33.3 mph), or within the range 41.4–65.88 km/h (25.7–40.9 mph) including error. The highest recorded value was 93.24 km/h (57.9 mph). A hunt consists of two phases, an initial fast acceleration phase when the cheetah tries to catch up with the prey, followed by slowing down as it closes in on it, the deceleration varying by the prey in question. The peak linear acceleration observed was 12m/s²,twice than horses and greater than greyhounds..[93][94]Cheetahs can accelerate up 3 m/s and decelerate up 4 m/s in a single stride.[93]Speed and acceleration values for a hunting cheetah may be different from those for a non-hunter because while engaged in the chase, the cheetah is more likely to be twisting and turning and may be running through vegetation.[93][95]The speeds attained by the cheetah may be only slightly greater than those achieved by thepronghornat 88.5 km/h (55.0 mph)[96]and thespringbokat 88 km/h (55 mph),[97]but the cheetah additionally has an exceptional acceleration.[98]

One stride of a galloping cheetah measures 4 to 7 m (13 to 23 ft); the stride length and the number of jumps increases with speed.[58]During more than half the duration of the sprint, the cheetah has all four limbs in the air, increasing the stride length.[99]Running cheetahs can retain up to 90% of the heat generated during the chase. A 1973 study suggested the length of the sprint is limited by excessive build-up of body heat when the body temperature reaches 40–41 °C (104–106 °F). However, a 2013 study recorded the average temperature of cheetahs after hunts to be 38.6 °C (101.5 °F), suggesting high temperatures need not cause hunts to be abandoned.[100][101]

The running speed of 71 mph (114 km/h) of the cheetah was obtained as an result of a single run of one individual by dividing the distance traveled for time spent. The run lasted 2.25 seconds and was supposed to have been 73 m (240 ft) long, but was later found to have been 59 m (194 ft) long. It was therefore discredited for a faulty method of measurement.[102] Cheetahs have subsequently been measured at running at a speed of 64 mph (103 km/h) as an average of three runs including in opposite direction, for a single individual, over a marked 200 m (220 yd) course, even starting the run 18 m (59 ft) behind the start line, starting the run already running on the course. Again dividing the distance by time, but this time to determine the maximum sustained speed, completing the runs in an average time of 7 seconds. Being a more accurate method of measurement, this test was made in 1965 but published in 1997.[103] Subsequently, with GPS-IMU collars, running speed was measured for wild cheetahs during hunts with turns and maneuvers, and the maximum speed recorded was 58 mph (93 km/h) sustained for 1–2 seconds. The speed was obtained by dividing the length by the time between footfalls of a stride.[93]Cheetahs can go from 0 to 97 km/h (0 to 60 mph) in less than 3 seconds.[104]

There are indirect ways to realize how fast are cheetah running. One case is known of a cheetah that overtook a young malePronghorn.Cheetahs can overtake a running antelope with head start of 140 m (150 yd). Both animals are assumed to be clocked at 80 km/h (50 mph) by speedometer reading when running alongside a vehicle at full gallop.[102]Cheetahs can easily capture gazelles at full gallop, clocked at 70–80 km/h (43–50 mph).[105]

The physiological reasons for speed in cheetahs are:

  • Small head and long lumbar region of the spine, 36.8% of the presacral vertebral column.[31][106][36]
  • Atibiaandradiuslonger than thefemurandhumerus(Femorotibial index: 101.9–105; Humeroradial index: 100.1–103.3).[31][36][106]
  • Elongated and slender long bones of the limbs, especially femur, tibia, humerus, radius andpelvis,specially theischium.[10][106][89]
  • A cool nose and enlarged respiratory passages that allow it to inhale and exhale more air with each breath and helping to dissipate body heat.[10]
  • A higher concentration of glycolytic fast-twitch muscle fibers than other cats and animals in general.[10][107][108][104]
  • Most of the locomotor muscle mass is concentrated proximally close to the body in shoulders, thighs and spine, and is reduced in shins and forearms. Long tendons finish off the distal locomotor muscles.[10][89]
  • Muscular hindlimbs form 19.8 % of the body mass, whereas forelimbs form 15.1 %.[89][109]Hamstrings,quadriceps,adductor muscles of the hipandPsoas major musclesare especially large.[110]

Ecology and behaviour

Cheetahs are active mainly during the day,[66]whereas other carnivores such as leopards and lions are active mainly at night;[63][98]These larger carnivores can kill cheetahs andstealtheir kills;[58]hence, thediurnaltendency of cheetahs helps them avoid larger predators in areas where they aresympatric,such as theOkavango Delta.In areas where the cheetah is the major predator (such as farmlands in Botswana and Namibia), activity tends to increase at night. This may also happen in highly arid regions such as the Sahara, where daytime temperatures can reach 43 °C (109 °F). Thelunar cyclecan also influence the cheetah's routine—activity might increase on moonlit nights as prey can be sighted easily, though this comes with the danger of encountering larger predators.[58][111]Hunting is the major activity throughout the day, with peaks during dawn and dusk.[64]Groups rest in grassy clearings after dusk. Cheetahs often inspect their vicinity at observation points such as elevations to check for prey or larger carnivores; even while resting, they take turns at keeping a lookout.[58]

Social organisation

Cheetahs have a flexible and complexsocial structureand tend to be more gregarious than several other cats (except the lion). Individuals typically avoid one another but are generally amicable; males may fight overterritoriesor access to females inoestrus,and on rare occasions such fights can result in severe injury and death. Females are not social and have minimal interaction with other individuals, barring the interaction with males when they enter their territories or during the mating season. Some females, generally mother and offspring or siblings, may rest beside one another during the day. Females tend to lead a solitary life or live with offspring in undefendedhome ranges;young females often stay close to their mothers for life but young males leave their mother's range to live elsewhere.[58][61][64]

Some males are territorial, and group together for life, forming coalitions that collectively defend a territory which ensures maximum access to females—this is unlike the behaviour of the male lion who mates with a particular group (pride) of females. In most cases, a coalition will consist of brothers born in the same litter who stayed together after weaning, but biologically unrelated males are often allowed into the group; in the Serengeti, 30% of members in coalitions are unrelated males.[64]If a cub is the only male in a litter, he will typically join an existing group, or form a small group of solitary males with two or three other lone males who may or may not be territorial. In theKalahari Desertaround 40% of the males live in solitude.[61][64]

Males in a coalition are affectionate toward each other,grooming mutuallyand calling out if any member is lost; unrelated males may face some aversion in their initial days in the group. All males in the coalition typically have equal access to kills when the group hunts together, and possibly also to females who may enter their territory.[112]A coalition generally has a greater chance of encountering and acquiring females for mating; however, its large membership demands greater resources than do solitary males.[61][64]A 1987 study showed that solitary and grouped males have a nearly equal chance of coming across females, but the males in coalitions are notably healthier and have better chances of survival than their solitary counterparts.[113]

Home ranges and territories

Unlike many other felids, among cheetahs, females tend to occupy larger areas compared to males.[61]Females typically disperse over large areas in pursuit of prey, but they are less nomadic and roam in a smaller area if prey availability in the area is high. As such, the size of their home range depends on the distribution of prey in a region. In central Namibia, where most prey species are sparsely distributed, home ranges average 554–7,063 km2(214–2,727 sq mi), whereas in the woodlands of thePhinda Game Reserve(South Africa), which have plentiful prey, home ranges are 34–157 km2(13–61 sq mi) in size.[64]Cheetahs can travel long stretches overland in search of food; a study in the Kalahari Desert recorded an average displacement of nearly 11 km (6.8 mi) every day and walking speeds ranged between 2.5 and 3.8 km/h (1.6 and 2.4 mph).[111]

Males are generally less nomadic than females; often males in coalitions (and sometimes solitary males staying far from coalitions) establish territories.[58][61]Whether males settle in territories or disperse over large areas forming home ranges depends primarily on the movements of females. Territoriality is preferred only if females tend to be more sedentary, which is more feasible in areas with plenty of prey. Some males, called floaters, switch between territoriality and nomadism depending on the availability of females.[64]A 1987 study showed territoriality depended on the size and age of males and the membership of the coalition.[113]The ranges of floaters averaged 777 km2(300 sq mi) in the Serengeti to 1,464 km2(565 sq mi) in central Namibia. In theKruger National Park(South Africa) territories were much smaller. A coalition of three males occupied a territory measuring 126 km2(49 sq mi), and the territory of a solitary male measured 195 km2(75 sq mi).[64]When a female enters a territory, the males will surround her; if she tries to escape, the males will bite or snap at her. Generally, the female can not escape on her own; the males themselves leave after they lose interest in her. They may smell the spot she was sitting or lying on to determine if she was in oestrus.[112]

The cheetah is a vocal felid with a broad repertoire of calls and sounds; theacousticfeatures and the use of many of these have been studied in detail.[114]The vocal characteristics, such as the way they are produced, are often different from those of other cats.[115]For instance, a study showed that exhalation is louder than inhalation in cheetahs, while no such distinction was observed in thedomestic cat.[116][117]Listed below are some commonly recorded vocalisations observed in cheetahs:

  • Chirping: A chirp (or a "stutter-bark" ) is an intense bird-like call and lasts less than a second. Cheetahs chirp when they are excited, for instance, when gathered around a kill. Other uses include summoning concealed or lost cubs by the mother, or as a greeting or courtship between adults.[115]The cheetah's chirp is similar to the soft roar of the lion, and its churr as the latter's loud roar.[114]A similar but louder call ('yelp') can be heard from up to 2 km (1.2 mi) away; this call is typically used by mothers to locate lost cubs, or by cubs to find their mothers and siblings.[58][60]
  • Churring (or churtling): A churr is a shrill, staccato call that can last up to two seconds. Churring and chirping have been noted for their similarity to the soft and loud roars of the lion. It is produced in similar context as chirping, but a study of feeding cheetahs found chirping to be much more common.[66][115]
  • Purring: Similar to purring in domestic cats but much louder, it is produced when the cheetah is content, and as a form of greeting or when licking one another.[58][115]It involves continuous sound production alternating betweenegressiveandingressiveairstreams.[118]
  • Agonistic sounds: These include bleating, coughing, growling, hissing, meowing and moaning (or yowling). A bleat indicates distress, for instance when a cheetah confronts a predator that has stolen its kill. Growls, hisses and moans are accompanied by multiple, strong hits on the ground with the front paw, during which the cheetah may retreat by a few metres.[114][115][119]A meow, though a versatile call, is typically associated with discomfort or irritation.[114][120]
  • Other vocalisations: Individuals can make a gurgling noise as part of a close, amicable interaction.[58]A "nyam nyam" sound may be produced while eating. Apart from chirping, mothers can use a repeated "ihn ihn" is to gather cubs, and a "prr prr" is to guide them on a journey. A low-pitched alarm call is used to warn the cubs to stand still. Bickering cubs can let out a "whirr" —the pitch rises with the intensity of the quarrel and ends on a harsh note.[66][115]

Another major means of communication is byscent—the male will often raise his tail andspray urineon elevated landmarks such as a tree trunks, stumps or rocks; other cheetahs will sniff these landmarks and repeat the ritual. Females may also show marking behaviour but less prominently than males do. Females in oestrus will show maximum urine-marking, and their excrement can attract males from far off. In Botswana, cheetahs are frequently captured by ranchers to protect livestock by setting up traps in traditional marking spots; the calls of the trapped cheetah can attract more cheetahs to the place.[66][61]

Touch and visual cues are other ways of signalling in cheetahs. Social meetings involve mutual sniffing of the mouth, anus and genitals. Individuals will groom one another, lick each other's faces and rub cheeks. However, they seldom lean on or rub their flanks against each other. The tear streaks on the face can sharply define expressions at close range. Mothers probably use the alternate light and dark rings on the tail to signal their cubs to follow them.[66]

Diet and hunting

The cheetah is a carnivore that hunts small to medium-sized prey weighing 20 to 60 kg (44 to 132 lb), but mostly less than 40 kg (88 lb). Its primary prey are medium-sized ungulates. They are the major component of the diet in certain areas, such asDamaandDorcasgazelles in the Sahara,impalain the eastern and southern African woodlands, springbok in the aridsavannasto the south andThomson's gazellein the Serengeti. Smaller antelopes like thecommon duikerare frequent prey in the southern Kalahari. Larger ungulates are typically avoided, thoughnyala,whose males weigh around 120 kg (260 lb), were found to be the major prey in a study in the Phinda Game Reserve. In Namibia cheetahs are the major predators of livestock.[8][58][121]The diet of the Asiatic cheetah consists ofchinkara,desert hare,goitered gazelle,urial,wild goats,and livestock; in India cheetahs used to prey mostly onblackbuck.[64][122]

Prey preferences and hunting success vary with the age, sex and number of cheetahs involved in the hunt and on the vigilance of the prey. Generally, only groups of cheetahs (coalitions or mother and cubs) will try to kill larger prey; mothers with cubs especially look out for larger prey and tend to be more successful than females without cubs. Individuals on the periphery of the prey herd are common targets; vigilant prey which would react quickly on seeing the cheetah are not preferred.[45][58][123]

Cheetahs are one of the most iconicpursuit predators,hunting primarily throughout the day, sometimes with peaks atdawnanddusk;they tend to avoid larger predators like the primarily nocturnal lion.[64]Cheetahs in the Sahara andMaasai Marain Kenya hunt after sunset to escape the high temperatures of the day.[124]Cheetahs use theirvisionto hunt instead of their sense of smell; they keep a lookout for prey from resting sites or low branches. The cheetah will stalk its prey, trying to conceal itself in cover, and approach as close as possible, often within 60 to 70 m (200 to 230 ft) of the prey (or even closer for less alert prey). Alternatively the cheetah can lie hidden in cover and wait for the prey to come nearer. A stalking cheetah assumes a partially crouched posture, with the head lower than the shoulders; it will move slowly and be still at times. In areas of minimal cover, the cheetah will approach within 200 m (660 ft) of the prey and start the chase. The chase typically lasts a minute; in a 2013 study, the length of chases averaged 173 m (568 ft), and the longest run measured 559 m (1,834 ft). The cheetah can give up the chase if it is detected by the prey early or if it cannot make a kill quickly. Being lightly build, cheetahs lack the raw strength to tackle down the prey, and instead catch the prey by performing a kind offoot sweepby hitting the prey's leg or rump with the forepaw or using the strong dewclaw to knock the prey off its balance. Such tripping during a high-speed chase will cause the prey to fall down hard with much force that sometimes even breaks some of its limbs,[58][66]and allow the cheetah to then pounce on the fallen and vulnerable prey.

Cheetahs can decelerate dramatically towards the end of the hunt, slowing down from 93 km/h (58 mph) to 23 km/h (14 mph) in just three strides, and can easily follow any twists and turns the prey makes as it tries to flee.[64]To kill medium- to large-sized prey, the cheetahbites the prey's throattostrangleit, maintaining the bite for around five minutes, within which the prey succumbs toasphyxiationand stops struggling. A bite on the nape of the neck or the snout (and sometimes on the skull) suffices to kill smaller prey.[58][66]Cheetahs have an average hunting success rate of 25–40%, higher for smaller and more vulnerable prey.[64][79]

Once the hunt is over, the prey is taken near a bush or under a tree; the cheetah, highly exhausted after the chase, rests beside the kill and pants heavily for five to 55 minutes. Meanwhile, cheetahs nearby, who did not take part in the hunt, might feed on the kill immediately. Groups of cheetah devour the kill peacefully, though minor noises and snapping may be observed.[58]Cheetahs can consume large quantities of food; a cheetah at theEtosha National Park(Namibia) was found to consume as much as 10 kg (22 lb) within two hours.[125]However, on a daily basis, a cheetah feeds on around 4 kg (8.8 lb) meat.[66]Cheetahs, especially mothers with cubs, remain cautious even as they eat, pausing to look around for fresh prey or for predators who may steal the kill.[126]

Cheetahs move their heads from side to side so the sharp carnassial teeth tear the flesh, which can then be swallowed without chewing. They typically begin with the hindquarters, and then progress toward the abdomen and the spine. Ribs are chewed on at the ends, and the limbs are not generally torn apart while eating. Unless the prey is very small, the skeleton is left almost intact after feeding on the meat. Cheetahs might lose up 13-14 % of their kills to larger and stronger carnivores.[105][58]To defend itself or its prey, a cheetah will hold its body low to the ground and snarl with its mouth wide open, the eyes staring threateningly ahead and the ears folded backward. This may be accompanied by moans, hisses and growls, and hitting the ground with the forepaws.[66]Cheetahs have rarely been observedscavengingkills; this may be due tovulturesand spotted hyena adroitly capturing and consuming heavycarcasseswithin a short time.[58][127]

Cheetahs appear to have a comparatively higher hunting success rate than other predators.[58]Their success rate for hunting Thomson gazelles is 70 %, compared to 57 % of African wild dogs, 33 % of spotted hyenas, and 26 % of lions.[105]Their success rate for hunting impalas is 26 %, compared to 16 % of leopards, and 15.5 % of lone African wild dogs.[93][128][129][130]

Reproduction and life cycle

Cheetahs areinduced ovulatorsand can breed throughout the year. Females can have their first litter at two to three years of age.Polyestrous,females have an oestrus ( "heat" ) cycle is 12 days long on average, but it can vary from three days to a month. A female can conceive again after 17 to 20 months from giving birth, or even sooner if a whole litter is lost. Males can breed at less than two years of age in captivity, but this may be delayed in the wild until the male acquires a territory.[2][66][112][131]A 2007 study showed that females who gave birth to more litters early in their life often died younger, indicating a trade-off between longevity and yearly reproductive success.[132]

Urine-marking in males can become more pronounced when a female in their vicinity comes into oestrus. Males, sometimes even those in coalitions, fight among one another to secure access to the female.[133]Often one male will eventually windominanceover the others and mate with the female, though a female can mate with different males.[134]Mating begins with the male approaching the female, who lies down on the ground; individuals often chirp, purr or yelp at this time. No courtship behaviour is observed; the male immediately secures hold of the female's nape, and copulation takes place. The pair then ignore each other, but meet and copulate a few more times three to five times a day for the next two to three days before finally parting ways.[2][66][135]

After agestationof nearly three months, a litter of one to eight cubs is born (though those of three to four cubs are more common). Births take place at 20–25 minute intervals in a sheltered place such as thick vegetation. The eyes are shut at birth, and open in four to 11 days. Newborn cubs might spit a lot and make soft churring noises; they start walking by two weeks. Their nape, shoulders and back are thickly covered with long bluish-grey hair, called a mantle, which gives them amohawk-typeappearance; this fur is shed as the cheetah grows older.[66][14]A study suggested that this mane gives a cheetah cub the appearance of ahoney badger,and could act as camouflage from attacks by these badgers or predators that tend to avoid them.[136]

Compared to other felids, cheetah cubs are highly vulnerable to several predators during the first few weeks of their life.[137][138]Mothers keep their cubs hidden in dense vegetation for the first two months and nurse in the early morning. The mother is extremely vigilant at this stage; she stays within 1 km (0.62 mi) of the lair, frequently visits her cubs, moves them every five to six days, and remains with them after dark. Despite trying to make minimal noise, she cannot generally defend her litter from predators. Predation is the leading cause of mortality in cheetah cubs; a study showed that in areas with a low density of predators (such as Namibian farmlands) around 70% of the cubs make it beyond the age of 14 months, whereas in areas like the Serengeti National Park, where several large carnivores exist, the survival rate was just 17%. Deaths also occur from starvation if their mothers abandon them, fires, or pneumonia because of exposure to bad weather.[66][112]Generation lengthof the cheetah is six years.[139]

Cubs start coming out of the lair at two months of age, trailing after their mother wherever she goes. At this point the mother nurses less and brings solid food to the cubs; they retreat away from the carcass in fear initially, but gradually start eating it. The cubs might purr as the mother licks them clean after the meal. Weaning occurs at four to six months. To train her cubs in hunting, the mother will catch and let go of live prey in front of her cubs.[112]Cubs' play behaviour includes chasing, crouching, pouncing and wrestling; there is plenty of agility, and attacks are seldom lethal.[66][112]Playing can improve catching skills in cubs, though the ability to crouch and hide may not develop remarkably.[140]

Cubs as young as six months try to capture small prey like hares and young gazelles. However, they may have to wait until as long as 15 months of age to make a successful kill on their own. At around 20 months, offspring become independent; mothers might have conceived again by then. Siblings may remain together for a few more months before parting ways. While females stay close to their mothers, males move farther off.[66][112][141]The lifespan of wild cheetahs is 14 to 15 years for females, and their reproductive cycle typically ends by 12 years of age; males generally live as long as ten years.[1]

Distribution and habitat

The historic and present range of the cheetah

Cheetahs occur in various habitats, such as the grasslands of theSerengeti

In eastern and southern Africa, the cheetah occurs mostly in savannas like the Kalahari and Serengeti. In central, northern and western Africa, it inhabits arid mountain ranges and valleys; in the harsh climate of the Sahara, it prefers high mountains, which receive more rainfall than the surrounding desert. The vegetation and water resources in these mountains support antelopes. In Iran, it occurs in hilly terrain of deserts at elevations up to 2,000–3,000 m (6,600–9,800 ft), where annual precipitation is generally below 100 mm (3.9 in); the primary vegetation in these areas is thinly distributed shrubs, less than 1 m (3 ft 3 in) tall.[1][64][111]

The cheetah inhabits a variety ofecosystemsand appears to be less selective in habitat choice than other felids; it prefers areas with greater availability of prey, good visibility and minimal chances of encountering larger predators. It seldom occurs in tropical forests. It has been reported at the elevation of 4,000 m (13,000 ft). An open area with some cover, such as diffused bushes, is probably ideal for the cheetah because it needs to stalk and pursue its prey over a distance. This also minimises the risk of encountering larger carnivores. The cheetah tends to occur in low densities typically between 0.3 and 3.0 adults per 100 km2(39 sq mi); these values are 10–30% of those reported for leopards and lions.[1][111]

Historical range

In prehistoric times, the cheetah was distributed throughout Africa, Asia and Europe.[58]It gradually fell to extinction in Europe, possibly because of competition with the lion.[14]Today the cheetah has beenextirpatedin most of its historical range; the numbers of the Asiatic cheetah had begun plummeting since the late 1800s, long before the other subspecies started their decline. As of 2017, cheetahs occur in just nine per cent of their erstwhile range in Africa, mostly in unprotected areas.[25]

In the past until the mid-20th century, the cheetah ranged across vast stretches in Asia, from theArabian Peninsulain the west to the Indian subcontinent in the east, and as far north as theAralandCaspianSeas.[142]A few centuries ago the cheetah was abundant in India, and its range coincided with the distribution of major prey like the blackbuck.[58]However, its numbers in India plummeted from the 19th century onward; Divyabhanusinh of theBombay Natural History Societynotes that the last three individuals in the wild were killed by Maharaja Ramanuj Pratap Singh ofSurgujain 1947.[143][144]The last confirmed sighting in India was of a cheetah that drowned in a well near Hyderabad in 1957.[145]In Iran there were around 400 cheetahs beforeWorld War II,distributed across deserts and steppes to the east and the borderlands with Iraq to the west; the numbers were falling because of a decline in prey. In Iraq, cheetahs were reported fromBasrain the 1920s. Conservation efforts in the 1950s stabilised the population, but prey species declined again in the wake of theIranian Revolution(1979) and theIran–Iraq War(1980–1988), leading to a significant contraction of the cheetah's historical range in the region.[25][146]

In 1975, the cheetah population was estimated at 15,000 individuals throughoutSub-Saharan Africa,following the first survey in this region byNorman Myers.The range covered most of eastern and southern Africa, except for the desert region on the western coast of modern-day Angola and Namibia.[147]In the following years, cheetah populations across the region have become smaller and more fragmented as their natural habitat has been modified dramatically.[148]

Present distribution

The cheetah occurs mostly in eastern and southern Africa; its presence in Asia is limited to the central deserts of Iran, though there have been unconfirmed reports of sightings in Afghanistan, Iraq and Pakistan in the last few decades.[1][25]The global population of cheetahs was estimated at nearly 7,100 mature individuals in 2016. The Iranian population appears to have decreased from 60–100 individuals in 2007 to 43 in 2016, distributed in three subpopulations over less than 150,000 km2(58,000 sq mi) in Iran's central plateau.[23][149]The largest population of nearly 4,000 individuals is sparsely distributed over Angola, Botswana, Mozambique, Namibia, South Africa and Zambia. Another population in Kenya and Tanzania comprises about 1,000 individuals. All other cheetahs occur in small, fragmented groups of less than 100 individuals each. Populations are thought to be declining.[23]

Threats

The cheetah is threatened by several factors, likehabitat lossand fragmentation of populations. Habitat loss is caused mainly by the introduction of commercial land use, such as agriculture and industry.[1]It is further aggravated by ecological degradation, likewoody plant encroachment,which is common in southern Africa.[150][151][152]Moreover, the species apparently requires a sizeable area to live in as indicated by its low population densities. Shortage of prey and conflict with other species such as humans and large carnivores are other major threats.[1][153]The cheetah appears to be less capable of coexisting with humans than the leopard.[154]With 76% of its range consisting of unprotected land, the cheetah is often targeted by farmers and pastoralists who attempt to protect their livestock, especially in Namibia.[155]Illegalwildlife tradeand trafficking is another problem in some places (like Ethiopia). Some tribes, like theMaasai peoplein Tanzania, have been reported to use cheetah skins in ceremonies.[5][31]Roadkillis another threat, especially in areas where roads have been constructed near natural habitat or protected areas. Cases of roadkill involving cheetahs have been reported from Kalmand,Touran National Park,andBafqin Iran.[1]The reduced genetic variability makes cheetahs more vulnerable to diseases;[48]however, the threat posed by infectious diseases may be minor, given the low population densities and hence a reduced chance of infection.[1]

Conservation

The cheetah has been classified asVulnerableby the IUCN; it is listed under AppendixI of theCMSand AppendixI ofCITES.[1]TheEndangered Species Actenlists the cheetah as Endangered.[156]

In Africa

Until the 1970s, cheetahs and other carnivores were frequently killed to protect livestock in Africa. Gradually the understanding of cheetah ecology increased and their falling numbers became a matter of concern. The De Wildt Cheetah and Wildlife Centre was set up in 1971 in South Africa to provide care for wild cheetahs regularly trapped or injured by Namibian farmers.[5]By 1987, the first major research project to outline cheetah conservation strategies was underway.[157]TheCheetah Conservation Fund,founded in 1990 in Namibia, put efforts into field research and education about cheetahs on the global platform.[5]The CCF runs a cheetah genetics laboratory, the only one of its kind, inOtjiwarongo(Namibia);[158]"Bushblok" is an initiative to restore habitat systematically through targeted bush thinning and biomass utilisation.[151][159]Several more cheetah-specific conservation programmes have since been established, like Cheetah Outreach in South Africa.[5]

The Global Cheetah Action Plan Workshop in 2002 laid emphasis on the need for a range-wide survey of wild cheetahs to demarcate areas for conservation efforts and on creating awareness through training programs.[160]The Range Wide Conservation Program for Cheetah and African Wild Dogs (RWCP) began in 2007 as a joint initiative of the IUCN Cat and Canid Specialist Groups, theWildlife Conservation Societyand theZoological Society of London.National conservation plans have been developed successfully for several African countries.[161][162]In 2014, the CITES Standing Committee recognised the cheetah as a "species of priority" in their strategies in northeastern Africa to counter wildlife trafficking.[163]In December 2016 the results of an extensive survey detailing the distribution and demography of cheetahs throughout the range were published; the researchers recommended listing the cheetah asEndangeredon the IUCN Red List.[23]

The cheetah was reintroduced in Malawi in 2017.[164]

In Asia

In 2001, the Iranian government collaborated with the CCF, the IUCN,Panthera Corporation,UNDPand the Wildlife Conservation Society on the Conservation of Asiatic Cheetah Project (CACP) to protect the natural habitat of the Asiatic cheetah and its prey.[165][166]In 2004, the Iranian Centre for Sustainable Development (CENESTA) conducted an international workshop to discuss conservation plans with local stakeholders.[5]Iran declared 31August as National Cheetah Day in 2006.[167]The Iranian Cheetah Strategic Planning meet in 2010 formulated a five-year conservation plan for Asiatic cheetahs.[5]The CACP Phase II was implemented in 2009, and the third phase was drafted in 2018.[168]

During the early 2000s scientists from theCentre for Cellular and Molecular Biology(Hyderabad) proposed a plan tocloneAsiatic cheetahs from Iran for reintroduction in India, but Iran denied the proposal.[169]In September 2009, the Minister of Environment and Forests assigned theWildlife Trust of Indiaand theWildlife Institute of Indiawith examining the potential of importing African cheetahs to India.[170]Kuno Wildlife SanctuaryandNauradehi Wildlife Sanctuarywere suggested as reintroduction sites for the cheetah because of their high prey density.[171]However, plans for reintroduction were stalled in May 2012 by theSupreme Court of Indiabecause of a political dispute and concerns over introducing a non-native species to the country. Opponents stated the plan was "not a case of intentional movement of an organism into a part of its native range".[172][173]On 28 January 2020, the Supreme Court allowed the central government to introduce cheetahs to a suitable habitat in India on an experimental basis to see if they can adapt to it.[174][175]In 2020, India signed a memorandum of understanding with Namibia as part of Project Cheetah.[176]In July 2022, it was announced that eight cheetahs would be transferred from Namibia to India in August.[177]The eight cheetahs were released into Kuno on 17 September 2022, by Prime MinisterNarendra Modi.[178]

The cheetah shows little aggression toward humans, and can be tamed easily, as it has been since antiquity.[14]The earliest known depictions of the cheetah are from theChauvet Cavein France, dating back to 32,000–26,000 BC.[179]According to historians such as Heinz Friederichs andBurchard Brentjes,the cheetah was first tamed inSumerand this gradually spread out to central and northern Africa, from where it reached India. The evidence for this is mainly pictorial; for instance, a Sumerian seal dating back toc. 3000 BC,featuring a long-legged leashed animal has fueled speculation that the cheetah was first tamed in Sumer. However,Thomas Allsenargues that the depicted animal might be a large dog.[180]Other historians, such asFrederick Zeuner,have opined that ancient Egyptians were the first to tame the cheetah, from where it gradually spread into central Asia, Iran and India.[181]

In comparison, theories of the cheetah's taming in Egypt are stronger and include timelines proposed on this basis.[181]Mafdet,one of the ancient Egyptian deities worshiped during theFirst Dynasty(3100–2900BC), was sometimes depicted as a cheetah. Ancient Egyptians believed the spirits of deceasedpharaohswere taken away by cheetahs.[179]Reliefs in theDeir el-Baharitemple complex tell of an expedition by Egyptians to theLand of Puntduring the reign ofHatshepsut(1507–1458BC) that fetched, among other things, animals called "panthers". During theNew Kingdom(16th to 11th centuries BC), cheetahs were common pets for royalty, whoadornedthem with ornate collars and leashes.[181]Rock carvings depicting cheetahs dating back to 2000–6000 years ago have been found inTwyfelfontein;little else has been discovered in connection to the taming of cheetahs (or other cats) in southern Africa.[179]

Hunting cheetahs are known inpre-Islamic Arabic artfrom Yemen.[182]Hunting with cheetahs became more prevalent toward the seventh centuryAD. In the Middle East, the cheetah would accompany the nobility to hunts in a special seat on the back of the saddle. Taming was an elaborate process and could take a year to complete.[179]TheRomansmay have referred to the cheetah as theleopardos(λεοπάρδος) orleontopardos(λεοντόπαρδος), believing it to be a hybrid between a leopard and a lion because of the mantle seen in cheetah cubs and the difficulty of breeding them in captivity.[183]A Roman hunting cheetah is depicted in a 4th-century mosaic from Lod, Israel.[184]Cheetahs continued to be used into theByzantine periodof theRoman empire,with "hunting leopards" being mentioned in theCynegetica(283/284 AD).[183][185][186]

In eastern Asia, records are confusing as regional names for the leopard and the cheetah may be used interchangeably. The earliest depiction of cheetahs from eastern Asia dates back to theTang dynasty(7th to 10th centuriesAD); paintings depict tethered cheetahs and cheetahs mounted on horses. Chinese emperors would use cheetahs andcaracalsas gifts. In the 13th and 14th centuries, theYuanrulers bought numerous cheetahs from the western parts of the empire and from Muslim merchants. According to theMing Shilu,the subsequentMing dynasty(14th to 17th centuries) continued this practice.[181]Tomb figurines from the Mongol empire, dating back to the reign of Kublai Khan (1260–1294AD), represent cheetahs on horseback.[179]TheMughalrulerAkbar the Great(1556–1605AD) is said to have kept as many as 1000khasa(imperial) cheetahs.[79][179]His sonJahangirwrote in his memoirs,Tuzk-e-Jahangiri,that only one of them gave birth.[181]Mughal rulers trained cheetahs and caracals in a similar way as the western Asians, and used them to hunt game, especially blackbuck. The rampant hunting severely affected the populations of wild animals in India; by 1927, cheetahs had to be imported from Africa.[179]

In captivity

The first cheetah to be brought into captivity in a zoo was at theZoological Society of Londonin 1829. Early captive cheetahs showed a high mortality rate, with an average lifespan of 3–4 years. After trade of wild cheetahs was delimited by the enforcement of CITES in 1975, more efforts were put into breeding in captivity; in 2014 the number of captive cheetahs worldwide was estimated at 1730 individuals, with 87% born in captivity.[5][187]

Mortality under captivity is generally high; in 2014, 23% of the captive cheetahs worldwide died under one year of age, mostly within a month of birth.[187]Deaths result from several reasons—stillbirths, birth defects,cannibalism,hypothermia,maternal neglect, and infectious diseases.[188]Compared to other felids, cheetahs need specialised care because of their higher vulnerability to stress-induced diseases; this has been attributed to their low genetic variability and factors of captive life.[189]Common diseases of cheetahs includefeline herpesvirus,feline infectious peritonitis,gastroenteritis,glomerulosclerosis,leukoencephalopathy,myelopathy,nephrosclerosisandveno-occlusive disease.[189][190]High density of cheetahs in a place, closeness to other large carnivores in enclosures, improper handling, exposure to public and frequent movement between zoos can be sources of stress for cheetahs. Recommended management practices for cheetahs include spacious and ample access to outdoors, stress minimisation by exercise and limited handling, and following proper hand-rearing protocols (especially for pregnant females).[191]

Wild cheetahs are far more successful breeders than captive cheetahs;[192]this has also been linked to increased stress levels in captive individuals.[189]In a study in the Serengeti, females were found to have a 95% success rate in breeding, compared to 20% recorded for North American captive cheetahs in another study.[131][193]On 26 November 2017, a female cheetah gave birth to eight cubs in theSaint Louis Zoo,setting a record for the most births recorded by theAssociation of Zoos and Aquariums.[194]Chances of successful mating in captive males can be improved by replicating social groups such as coalitions observed in the wild.[195]

Attacks on humans

There are no documented records of lethal attacks on humans by wild cheetahs.[196]However, there have been instances of people being fatally mauled by captive cheetahs. In 2007, a 37-year-old woman from Antwerp was killed by a cheetah in a Belgian zoo after sneaking into its cage outside of visiting hours.[197]In 2017, a three-year-old child was attacked by a captive cheetah on a farm inPhilippolis,South Africa.Despite being airlifted to a hospital inBloemfontein,the boy died from his injuries.[198]

In culture

The cheetah has been widely portrayed in a variety of artistic works. InBacchus and Ariadne,anoil paintingby the 16th-century Italian painterTitian,the chariot of theGreekgodDionysus(Bacchus) is depicted as being drawn by two cheetahs. The cheetahs in the painting were previously considered to be leopards.[199]In 1764, English painterGeorge Stubbscommemorated the gifting of a cheetah toGeorge IIIby the English Governor ofMadras,Sir George Pigotin his paintingCheetah with Two Indian Attendants and a Stag.The painting depicts a cheetah, hooded and collared by two Indian servants, along with astagit was supposed to prey upon.[200]The 1896 paintingThe Caressby the 19th-century Belgiansymbolist painterFernand Khnopffis a representation of the myth ofOedipusand theSphinxand portrays a creature with a woman's head and a cheetah's body.[201]

In 1969,Joy Adamson,ofBorn Freefame, wroteThe Spotted Sphinx,a biography of her pet cheetah Pippa.[203]Hussein, An Entertainment,a novel byPatrick O'Brianset in theBritish Rajperiod in India, illustrates the practice of royalty keeping and training cheetahs to hunt antelopes.[204]The bookHow It Was with Doomstells the true story of a family raising an orphaned cheetah cub named Dooms in Kenya. The 2005 filmDumawas based loosely on this book.[205]The animated seriesThunderCatshad a character named "Cheetara", an anthropomorphic cheetah, voiced byLynne Lipton.[206]Comic book heroineWonder Woman's chief adversary is Barbara Ann Minerva aliasThe Cheetah.[207]

TheBill Thomas CheetahAmerican racing car, aChevrolet-based coupe first designed and driven in 1963, was an attempt to challengeCarroll Shelby'sShelby Cobrain American sports car competition of the 1960s. Because only two dozen or fewer chassis were built, with only a dozen complete cars, the Cheetah was neverhomologatedfor competition beyond prototype status; its production ended in 1966.[208]In 1986,Frito-LayintroducedChester Cheetah,ananthropomorphiccheetah, as the mascot for their snack foodCheetos.[209]TheMac OS X 10.0was code-named "Cheetah".[210]
