A gazelle is one of many antelope species in the genus Gazella /ɡəˈzɛlə/ . [2] There are also seven species included in two further genera; Eudorcas and Nanger , which were formerly considered subgenera of Gazella. A third former subgenus, Procapra , includes three living species of Asian gazelles.
Gazelles are known as swift animals. Some can run at bursts as high as 100 km/h (60 mph) or run at a sustained speed of 50 km/h (30 mph). [3] Gazelles are found mostly in the deserts, grasslands, and savannas of Africa, but they are also found in southwest and central Asia and the Indian subcontinent. They tend to live in herds, and eat fine, easily digestible plants and leaves.
Gazelles are relatively small antelopes, most standing 60–110 cm (2–3.5 ft) high at the shoulder, and are generally fawn-colored.
The gazelle genera are Gazella, Eudorcas, and Nanger. The taxonomy of these genera is confused, and the classification of species and subspecies has been an unsettled issue. Currently, the genus Gazella is widely considered to contain about 10 species. [4] One subspecies is extinct: the Queen of Sheba's gazelle. Most surviving gazelle species are considered threatened to varying degrees. Closely related to the true gazelles are the Tibetan goa, and Mongolian gazelles (species of the genus Procapra), the blackbuck of Asia, and the African springbok.
One widely familiar gazelle is the African species Thomson's gazelle (Eudorcas thomsonii), sometimes referred to as a "tommie". It is around 60 to 70 cm (24 to 28 in) in shoulder height and is coloured brown and white with a distinguishing black stripe. The males have long, often curved, horns. Like many other prey species, tommies exhibit a distinctive behaviour of stotting (running and jumping high before fleeing) when they are threatened by predators such as cheetahs, lions, African wild dogs, crocodiles, hyenas, and leopards.
Gazelle is derived from French gazelle, Old French gazel, probably via Old Spanish gacel, probably from North African pronunciation of Arabic : غزالġazāl, [5] [6] Maghrebi pronunciation ġazēl. [7] To Europe it first came to Old Spanish and Old French, [7] and then around 1600 the word entered the English language. [8] The Arab people traditionally hunted the gazelle. Later appreciated for its grace, however, it became a symbol most commonly associated in Arabic literature with human female beauty. [9] [10] In many countries in northwestern Sub-Saharan Africa, the gazelle is commonly referred to as "dangelo", meaning "swift deer". [11]
The gazelle, like the antelope to which it is related, is the totem of many African families. Some examples include the Joof family of the Senegambia region, [12] [13] the Bagananoa of Botswana in Southern Africa (said to be descended from the BaHurutshe), [14] and the Eraraka (or Erarak) clan of Uganda. [15] As is common in many African societies, it is forbidden for the Joof or Eraraka to kill or touch the family totem. [13] [15]
One of the traditional themes of Arabic love poetry involves comparing the gazelle with the beloved, and linguists theorize ghazal , the word for love poetry in Arabic, is related to the word for gazelle. [16] It is related that the Caliph Abd al-Malik (646–705) freed a gazelle that he had captured because of her resemblance to his beloved:
O likeness of Layla, never fear!
For I am your friend, today, O wild gazelle!
Then I say, after freeing her from her fetters:
You are free for the sake of Layla, for ever! [16]
The theme is found in the ancient Hebrew Song of Songs. (8:14)
Come away, my beloved,
and be like a gazelle
or like a young stag
on the spice-laden mountains.
The gazelles are divided into three genera and numerous species. [17]
Fossils of genus Gazella are found in Miocene, Pliocene and Pleistocene deposits of Eurasia and Africa, which occupuied a broader distribution that modern members of the genus. The earliest members of the genus are known from the Middle Miocene of Africa, around 14 million years ago with members of the genus inhabiting Europe from the Late Miocene until their extinction in the region during the Early Pleistocene around 1.8 million years ago. [18]
Struthionidae is a family of flightless birds, containing the extant ostriches and their extinct relatives. The two extant species of ostrich are the common ostrich and Somali ostrich, both in the genus Struthio, which also contains several species known from Holocene fossils such as the Asian ostrich. The common ostrich is the more widespread of the two living species, and is the largest living bird species. The extinct genus Pachystruthio from the Late Pliocene-Early Pleistocene of Eurasia is one of the largest birds ever.
The Bovidae comprise the biological family of cloven-hoofed, ruminant mammals that includes cattle, bison, buffalo, antelopes, sheep and goats. A member of this family is called a bovid. With 143 extant species and 300 known extinct species, the family Bovidae consists of 11 major subfamilies and thirteen major tribes. The family evolved 20 million years ago, in the early Miocene.
The bovid subfamily Reduncinae or tribe Reduncini is composed of nine species of antelope, all of which dwell in marshes, floodplains, or other well-watered areas, including the waterbucks and reedbucks. These antelopes first appear in the fossil record 7.4 million years ago in Eurasia and 6.6 Mya in Africa.
Hadar or Hadar Formation is a paleontological fossil site located in Mille district, Administrative Zone 1 of the Afar Region, Ethiopia, 15 km upstream (west) of the A1 road's bridge across the Awash River.
The antilopines are even-toed ungulates belonging to the subfamily Antilopinae of the family Bovidae. The members of tribe Antilopini are often referred to as true antelopes, and include the gazelles, blackbucks, springboks, gerenuks, dibatags, and Central Asian gazelles. True antelopes occur in much of Africa and Asia, with the highest concentration of species occurring in East Africa in Sudan, Eritrea, Ethiopia, Somalia, Kenya, and Tanzania. The saiga inhabits Central and Western Asia, mostly in regions from the Tibetan Plateau and north of the Indian Subcontinent. The dwarf antelope species of tribe Neotragini live entirely in sub-Saharan Africa.
Aepyceros is a genus of African antelope that contains a single living species, the impala. It is the only known member of the tribe Aepycerotini.
Thomson's gazelle is one of the best known species of gazelles. It is named after explorer Joseph Thomson and is sometimes referred to as a "tommie". It is considered by some to be a subspecies of the red-fronted gazelle and was formerly considered a member of the genus Gazella within the subgenus Eudorcas, before Eudorcas was elevated to genus status.
Chalicotheriidae is an extinct family of herbivorous, odd-toed ungulate (perissodactyl) mammals that lived in North America, Eurasia, and Africa from the Middle Eocene to the Early Pleistocene. They are often called chalicotheres, a term which is also applied to the broader grouping of Chalicotherioidea. They are noted for their unusual morphology compared to other ungulates, such as their clawed forelimbs. Members of the subfamily Chalicotheriinae developed elongate gorilla-like forelimbs that are thought to have been used to grasp vegetation. They are thought to have been browsers on foliage as well as possibly bark and fruit.
Chasmaporthetes, also known as hunting or running hyena, is an extinct genus of hyenas distributed in Eurasia, North America, and Africa during the Pliocene-Pleistocene epochs, living from 4.9 million to 780,000 years ago, existing for about 4.12 million years. The genus probably arose from Eurasian Miocene hyenas such as Thalassictis or Lycyaena, with C. borissiaki being the oldest known representative. The species C. ossifragus was the only hyena to cross the Bering land bridge into the Americas, and ranged over what is now Arizona and Mexico during Blancan and early Irvingtonian Land Mammal ages, between 5.0 and 1.5 million years ago.
Xenocyon is an extinct group of canids, either considered a distinct genus or a subgenus of Canis. The group includes Canis (Xenocyon) africanus, Canis (Xenocyon) antonii and Canis (Xenocyon) falconeri that gave rise to Canis (Xenocyon) lycanoides. The hypercarnivorous Xenocyon is thought to be closely related and possibly ancestral to modern dhole and the African wild dog, as well as the insular Sardinian dhole.
Procapra is a genus of Asian gazelles, including three living species:
Gazella harmonae is an extinct gazelle which existed in what is now Ethiopia during the Pliocene epoch. It was described by Denis Geraads, René Bobe and Kaye Reed in 2012. Approximately the size of a living dorcas gazelle, the animal was noted for its unusual, spiral horn cores.
