Wildlife of Iran: The wildlife of Iran includes its flora and fauna and their natural habitats.  One of the most famous members of wildlife in Iran are the world's last surviving, critically endangered Asiatic cheetah ("Acinonyx jubatus venaticus") also known as the Iranian cheetah, which are today found nowhere else but in Iran.  Iran had lost all its elephants, lions and tigers by the 21st century.

Entabeni Game Reserve: The Entabeni Game Reserve, Entabeni means 'place of the mountain', is a 220 km2 private reserve situated in the Waterberg in Limpopo Province in northern South Africa.  The Entabeni Reserve is popular for safari trips because of the opportunity to see big game and a variety of birds and antelope species, as well as its beautiful scenery, and the fact that it is in a malaria-free zone.  The reserve is home to Transvaal lion, African bush elephant, South African giraffe, African leopard, South African cheetah, warthog, African buffalo, hippopotamus and other safari animals in a variety of habitats.

South African cheetah: The South African cheetah ("Acinonyx jubatus jubatus"), also known as the Namibian cheetah, is the most numerous and the nominate cheetah subspecies native to Southern Africa.  Since 1986, it has been classified as Vulnerable by the IUCN.  The South African cheetah live mainly in the lowland areas and deserts of the Kalahari, the savannahs of Okavango Delta and the grasslands of the Transvaal region in South Africa.  In Namibia, cheetahs are mostly found in farmlands.

Waterberg Plateau Park: Waterberg Plateau Park is a national park in central Namibia on the Waterberg Plateau, 68 km south-east of Otjiwarongo.  The plateau and the national park are named after the prominent table mountain that rises from the plateau, the Waterberg (Afrikaans: "Water Mountain" ).  The Waterberg Plateau is a particularly prominent location, elevating high above the plains of the Kalahari of Eastern Namibia.  Waterberg Park and some 405 km2 of surrounding land were declared a Nature Reserve in 1972.  As the plateau is largely inaccessible from beneath several of Namibia's endangered species were relocated in the early 1970s to protect them from predators and poaching to extinction.  The programme was very successful and Waterberg now supplies other Namibian parks with rare animals.  In 1989, the black rhinoceros was reintroduced to the area from Damaraland.

Helicobacter acinonychis: Helicobacter acinonychis is a bacterium in the Helicobacteraceae family, Campylobacterales order.  It was first isolated from cheetahs ("Acinonyx jubatus") with gastritis, so has been associated with this disease in this particular species and others of its kind.  It is Gram-negative, spiral-shaped, and grows under microaerophilic conditions.  The type strain is 90-119 (CCUG 29263, ATCC 51101).

Sarah (cheetah): Sarah, also known as Sahara, ( 2001 – 22 January 2016) was a female South African cheetah ("Acinonyx jubatus jubatus") that lived in the Cincinnati Zoo in Cincinnati, Ohio.  Sarah was known as the world's fastest land mammal according to National Geographic magazine.  She ran 100 meters in 5.95 seconds (up to 61 miles (98 km) an hour) in 2012 when she was 11 years old.  She died on 22 January 2016 at the age of 15.

Northwest African cheetah: The Northwest African cheetah ("Acinonyx jubatus hecki"), also known as the Senegal cheetah or Saharan cheetah, is a subspecies of cheetah native to Northwest Africa (particularly the central western Sahara desert and the Sahel).  It is classified as critically endangered by the IUCN, with a total world population estimated to be about 250 mature individuals.  The Northwest African cheetah was described by German zoologist Max Hilzheimer under the scientific name "Acinonyx hecki" in Senegal of West Africa in 1913.

Cheetah: The cheetah ("Acinonyx jubatus") is a large felid of the subfamily Felinae that occurs mainly in eastern and southern Africa and a few parts of Iran.  The only extant member of the genus "Acinonyx", the cheetah was first described by Johann Christian Daniel von Schreber in 1775.  The cheetah is characterised by a slender body, deep chest, spotted coat, a small rounded head, black tear-like streaks on the face, long thin legs and a 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 70 to at the shoulder, and weighs 21 - .  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.

Tanzanian cheetah: The Tanzanian cheetah ("Acinonyx jubatus raineyi" syn.  "Acinonyx jubatus fearsoni"), also commonly known as East African cheetah or Kenyan cheetah, is a subspecies of cheetah native to East Africa.  They live in grasslands and savannas of Tanzania, Kenya, Uganda and Somalia.  The Tanzanian cheetahs are inhabiting mainly the Serengeti ecosystem, the Maasai Mara and the Tsavo landscape.  The East African specimen was described by the American zoologist Edmund Heller under the trinomen "Felis jubatus raineyi" in British East Africa in 1913.

Sudan cheetah: The Sudan cheetah ("Acinonyx jubatus soemmeringii") is a cheetah subspecies native to Central and Northeast Africa.  It lives grasslands, savannahs, lowlands of the Nile Valley, inland Lake Chad, arid Sahelian and Saharan deserts and steppes. Its population is fragmented in several areas of South Sudan, Ethiopia, Chad, Somalia and the Central African Republic.  It is also nearly extinct in Sudan.  Other common names are Somali cheetah, Northeast African cheetah or Central African cheetah.  The Sudan specimen was first described by the Austrian zoologist Leopold Fitzinger under the scientific name "Cynailurus soemmeringii" in Bayuda Desert of colonial Sudan in 1855.
