Groves (2011) recognizes six Oryx species. The East African oryxes have traditionally been treated as a single species, Oryx beisa (and often even considered conspecific with the Gemsbok, O. gazella, of southwest Africa).According to Groves (2011), however, although they are very similar in appearance they are best treated as three distinct species: Beisa Oryx (O. beisa), found in northern and central Somalia and the Ogaden region of Ethiopia north to Berbera, west to Eritrea, and south into the Awash Valley; Galla Oryx (O. gallarum), found in northern Kenya and northeastern Uganda and extending into Somalia and southeastern Ethiopia; and Fringe-eared Oryx (O. callotis), found in southeastern Kenya and northeastern Tanzania. The fourth oryx species still living in the wild is the Gemsbok.
In addition to these four species are two species that went extinct in the wild, but persist in captivity and are the focus of reintroduction efforts. The Scimitar-horned Oryx (Oryx dammah)--both sexes of which have long, slender, hollow horns that are annulated (i.e. with ring-like divisions) for the basal third and curve over the back--used to be found on the southern and northern edges of the Sahara Desert. They did not inhabit the desert interior, as does the Addax (Addax nasomaculatus). The former range of the Scimitar-horned Oryx, which encompassed over 4 million square km, experiences prolonged droughts, the most recent of which extended from the 1960s to the early 1990s! The ongoing southward spread of the Sahara Desert likely contributed to the decline of this species. When sedentary, herds consisted of 10 to 30 or even 100 individuals. During migration, groups of 1000 or more would aggregate (an aggregation of 10,000 was reported from Chad in 1936). It is estimated the the wild population of Scimitar-horned Oryx once numbered around a million individuals. In addition to the expansion of the Sahara, the main causes of extinction were human population growth, motorized access to the desert, overhunting, and increased use of key habitats by livestock. The last known wild individuals were in Chad and Niger in the 1980s. Fortunately, captive populations were established beginning in the 1960s (around 4,000 captive animals are in the United Arab Emirates in a private collection and around 2,000 on private ranches in Texas, U.S.A.), so re-establishing wild Scimitar-horned Oryx populations is a possibility that is being actively pursued.
The only native oryx species outside Africa is the Arabian Oryx (Oryx leucoryx). This species was extinct in the wild by 1972, but since then free-ranging populations have been established in Israel, Oman, and Saudi Arabia. This species was formerly present throughout the Arabian Peninsula, extending north to Israel, Jordan, Kuwait, Iraq, Syria, and Sinai. Poaching and overhunting in Oman eliminated the last wild individuals. Fortunately, captive breeding efforts had begun in the 1950s and reintroduction efforts began in the early 1980s and are ongoing. The world captive population is around 6,000 to 7,000, but the re-introduced free-ranging populations include only around 250 mature individuals.

According to Fauna Europaea, the weevil genus name Oryx Tournier 1874 is an invalid synonym of Paroryx Reitter 1913 (presumably the genus name Oryx was not actually an available name in 1874 since it was already being used for the bovid mammal genus Oryx de Blainville 1816).
Oryx is a genus consisting of four large antelope species called oryxes. Their pelage is pale with contrasting dark markings in the face and on the legs, and their long horns are almost straight. The exception is the scimitar oryx, which lacks dark markings on the legs, only has faint dark markings on the head, has an ochre neck, and has horns that are clearly decurved.
The Arabian oryx was only saved from extinction through a captive-breeding program and reintroduction to the wild.[1] The scimitar oryx, which is now listed as extinct in the wild, also relies on a captive-breeding program for its survival.[2]
The term "oryx" comes from the Greek word ὄρυξ, óryx, for a type of antelope. The Greek plural form is óryges, although "oryxes" has been established in English. Herodotus mentions a type of gazelle in Libya called ὄρυς, orus, probably related to the verb ὀρύσσω, orussō, or ὀρύττω, oruttō,[3] meaning "to dig". White oryxes are known to dig holes in the sand.
The Arabian oryx (Oryx leucoryx, Arabic: المها), became extinct in the wild in 1972 in the Arabian Peninsula. It was reintroduced in 1982 in Oman, but poaching has reduced its numbers there. One of the largest populations of Arabian oryxes exists on Sir Bani Yas Island in the United Arab Emirates. Additional populations have been reintroduced in Qatar, Bahrain, Israel, Jordan, and Saudi Arabia. As of 2011, the total wild population is over 1,000, and 6,000–7,000 are being held in captivity. In 2011, the IUCN downgraded its threat category from extinct in the wild to vulnerable, the first species to have changed back in this way.[1][4][5]
The scimitar oryx, also called the scimitar-horned oryx (Oryx dammah), of North Africa, is now listed as extinct in the wild. Unconfirmed surviving populations have been reported in central Niger and Chad, and a semiwild population currently inhabiting a fenced nature reserve in Tunisia is being expanded for reintroduction to the wild in that country.[6] Several thousand are held in captivity around the world.[2]
The East African oryx (Oryx beisa) inhabits eastern Africa and the closely related gemsbok (Oryx gazella) inhabits southern Africa. The gemsbok is monotypic and the East African oryx has two subspecies; the common beisa oryx (O. b. beisa) and the fringe-eared oryx (O. b. callotis). In the past, both were considered subspecies of the gemsbok. The East African oryx is an endangered species,[7] whereas the gemsbok is not.[8]
Gemsbok were introduced in New Mexico by the Department of Game and Fish in the late 1960s and early 1970s as an experiment in offering a unique hunting opportunity to New Mexico residents. Between 1969 and 1973, 93 oryx were released onto White Sands Missile Range. White Sands Missile Range, located between the cities of Albuquerque, NM and El Paso, TX, is a 3,200 square mile US Army facility which also hosts White Sands National Park. The first atomic bomb was test detonated at Trinity Site near the northern boundary of the range. The gemsbok released onto the range quickly began to reproduce. Researchers believed that the population would never grow beyond 500 to 600 and would remain within the Tularosa Basin. However, the animals proved to be extremely opportunistic, and quickly spread into the San Andres Mountains to the north and west of Tularosa Basin. At one time, numbers of Oryx in New Mexico were estimated to be around 6,000 (original release numbers were less than 100). Today, numbers have been held around the 2,000 mark through managed hunting efforts. The success of the oryx in New Mexico is due in part to the abundance of food. In Africa, they eat grasses, forbs, and melons. In New Mexico, they feed on desert grasses, yucca, buffalo gourds, and mesquite bean pods. They are especially adapted to desert life and can go a long time without drinking water. This area also lacks a way to control the population. Lions and other natural predators cull the population in Africa, with only 10% of calves reaching one year of age. In New Mexico, predators like coyotes and mountain lions are not effective at controlling numbers, allowing the oryx to reproduce without restriction. [9] [10] [11] [12]

All oryx species prefer near-desert conditions and can survive without water for long periods. They live in herds of up to 600 animals. Newborn calves are able to run with the herd immediately after birth. Both males and females possess permanent horns. The horns are narrow and straight except in the scimitar oryx, where they curve backwards like a scimitar. The horns can be lethal: oryxes have been known to kill lions with them, and they are thus sometimes called sabre antelopes (not to be confused with the sable antelope). The horns also make the animals a prized game trophy, which has led to the near-extinction of the two northern species.
Between 1969 and 1977, the New Mexico Department of Game and Fish in the US intentionally released 95 gemsbok into its state's White Sands Missile Range[13] and that population is now estimated between 3,000 and 6,000 animals.[14] Within the state of New Mexico, oryxes are classified as "big game" and can be hunted.
The oryx is the national animal of Namibia, the State of Qatar, and the company Qatar Airways has an oryx as its logo.[15][16]
The main boss of the MMO game Realm of the Mad God is Oryx the Mad God, named after the creator of the original sprite sheets, Oryx. His four direct subordinates also bear the names of four South African species of oryx.
Oryxes appear briefly, along with many other species of animal, in the Talk Talk music video It's My Life.
In the video game Tom Clancy's Rainbow Six Siege, a playable defending operator nicknamed Oryx was introduced in Year 5 Season 1. His ability is called "Remah Dash," where he can charge to break holes in walls and knock down enemies.
Oryx is a nickname for a character in Margaret Atwood's book Oryx and Crake.
Oryx is also the main antagonist’s name in the video game Destiny: The Taken King, a god who seeks vengeance on the player, known as a Guardian, after they killed his son Crota. He is killed by the player in the raid “King’s Fall”. He is portrayed as “Oryx, the Taken King”.
The Oryx is mentioned in Pliny's Natural History, where he writes, "There is a wild beast, named by the Egyptians Oryx, which, when the star rises, is said to stand opposite to it, to look steadfastly at it, and then to sneeze, as if it were worshiping it."[17]
