Cheetah
The cheetah (Acinonyx jubatus) is a large cat and the fastest land 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 short snout and 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 65 kg (46 and 143 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 first scientifically described in the late 18th century. Four subspecies are recognised today that are native to Africa and central Iran. An African subspecies was introduced to India in 2022. It is now distributed mainly in small, fragmented populations in northwestern, eastern and southern Africa and central Iran. It lives in a variety of habitats such as savannahs in the Serengeti, arid mountain ranges in the Sahara, and hilly desert terrain.
The cheetah lives in three main social groups: females and their cubs, male "coalitions", and solitary males. While females lead a nomadic life searching for prey in large home ranges, males are more sedentary and instead establish much smaller territories in 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-sized ungulates such as impala, springbok and Thomson'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 a gestation of 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 by habitat loss, conflict with humans, poaching and high susceptibility to diseases. The global cheetah population was estimated at 6,517 individuals in 2021; it is listed as Vulnerable on the IUCN Red List. It has been widely depicted in art, literature, advertising, and animation. It was tamed in ancient Egypt and trained for hunting ungulates in the Arabian Peninsula and India. It has been kept in zoos since the early 19th century.
The vernacular name "cheetah" is derived from Hindustani Urdu: چیتا and Hindi: चीता (ćītā). This in turn comes from Sanskrit: चित्रय (Chitra-ya) meaning 'variegated', 'adorned' or 'painted'. In the past, the cheetah was often called "hunting leopard" because they could be tamed and used for coursing. The generic name Acinonyx probably derives from the combination of two Greek words: ἀκίνητος (akī́nētos) meaning 'unmoved' or 'motionless', and ὄνυξ (ónyx) meaning 'nail' or 'hoof'. A rough translation is "immobile nails", a reference to the cheetah's limited ability to retract its claws. A similar meaning can be obtained by the combination of the Greek prefix a– (implying a lack of) and κῑνέω (kīnéō) meaning 'to move' or 'to set in motion'. The specific name jubatus is Latin for 'crested, having a mane'.
A few old generic names such as Cynailurus and Cynofelis allude to the similarities between the cheetah and canids.
In 1777, Johann Christian Daniel von Schreber described the cheetah based on a skin from the Cape of Good Hope and gave it the scientific name Felis jubatus. Joshua Brookes proposed the generic name Acinonyx in 1828. In 1917, Reginald Innes Pocock placed the cheetah in a subfamily of its own, Acinonychinae, given its striking morphological resemblance to the greyhound and significant deviation from typical felid features; the cheetah was classified in Felinae in later taxonomic revisions.
In the 19th and 20th centuries, several cheetah zoological specimens were described; some were proposed as subspecies. A South African specimen with notably dense fur was proposed as (Felis lanea) by Philip Sclater in 1877 and became known as the "woolly cheetah". Its classification as a species was mostly disputed. There has been considerable confusion in the nomenclature of the cheetah and leopard (Panthera pardus) as authors often confused the two; some considered "hunting leopards" an independent species, or equal to the leopard.
