Hippotragini
A grazing antelope is any of the species of antelope that make up the subfamily Hippotraginae or Tribe (biology), tribe Hippotragini of the family (biology), family Bovidae. As grazers, rather than browsers, the "Hippo" in Hippotraginae refers to the slightly horse-like characteristics of body size and proportions: long legs and a solid body with a relatively thick muscular neck.

Bovidae
The Bovidae comprise the biological family of cloven-hoofed, ruminant mammals that includes cattle, bison, buffalo, antelopes, and caprines. A member of this family is called a bovid. With 143 extant species and 300 known extinct species, the family Bovidae consists of 11 (or two) major subfamilies and thirteen major tribes. The family evolved 20 million years ago, in the early Miocene. The bovids show great variation in size and pelage colouration. Excepting some domesticated forms, all male bovids have two or more horns, and in many species, females possess horns, too. The size and shape of the horns vary greatly, but the basic structure is always one or more pairs of simple bony protrusions without branches, often having a spiral, twisted or fluted form, each covered in a permanent sheath of keratin. Most bovids bear 30 to 32 teeth. Most bovids are diurnal. Social activity and feeding usually peak during dawn and dusk. Bovids typically rest before dawn, during midday ...

Bluebuck
The bluebuck (Afrikaans: bloubok ) or blue antelope (''Hippotragus leucophaeus'') is an extinct species of antelope that lived in South Africa until around 1800. It was smaller than the other two species in its genus ''Hippotragus,'' the roan antelope and sable antelope. The bluebuck was sometimes considered a subspecies of the roan antelope, but a genetic study has confirmed it as a distinct species. The largest mounted bluebuck specimen is tall at the withers. Its horns measure along the curve. The coat was a uniform bluish-grey, with a pale whitish belly. The forehead was brown, darker than the face. Its mane was not as developed as in the roan and sable antelopes; its ears were shorter and blunter, not tipped with black; and it had a darker tail tuft and smaller teeth. It also lacked the contrasting black and white patterns seen on the heads of its relatives. The bluebuck was a grazer, and may have calved where rainfall, and thus the availability of grasses, would peak. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Miocene
The Late Miocene (also known as Upper Miocene) is a sub-epoch of the Miocene epoch (geology), Epoch made up of two faunal stage, stages. The Tortonian and Messinian stages comprise the Late Miocene sub-epoch, which lasted from 11.63 Ma (million years ago) to 5.333 Ma. The evolution of life The gibbons (family Hylobatidae) and orangutans (genus ''Pongo'') are the first groups to split from the line leading to the hominins, including humans, then gorillas (genus ''Gorilla''), and finally, chimpanzees and bonobos (genus ''Pan (genus), Pan''). The splitting date between hominin and chimpanzee lineages is placed by some between 4 to 8 million years ago, that is, during the Late Miocene.

Sable Antelope
The sable antelope (''Hippotragus niger'') is an antelope which inhabits wooded savanna in East and Southern Africa, from the south of Kenya to South Africa, with a separate population in Angola. Taxonomy The sable antelope shares the genus ''Hippotragus'' with the extinct bluebuck (''H. leucophaeus'') and the roan antelope (''H. equinus''), and is a member of the family Bovidae. In 1996, an analysis of mitochondrial DNA extracted from a mounted specimen of the bluebuck showed that it is outside the clade containing the roan and sable antelopes. The cladogram below shows the position of the sable antelope among its relatives, following the 1996 analysis: Subspecies ''Hipotragus niger'' has four subspecies: * The southern sable antelope (''H. n. niger''; also known as the common sable antelope, black sable antelope, Matsetsi sable antelope or South Zambian sable antelope) is regarded as the nominate subspecies, as it was the first one to be described and named in 1838.

Addax (Addax Nasomaculatus) Adult Male And Juvenile
The addax (''Addax nasomaculatus''), also known as the white antelope and the screwhorn antelope, is an antelope native to the Sahara Desert. The only member of the genus ''Addax'', it was first described scientifically by Henri de Blainville in 1816. As suggested by its alternative name, the pale antelope has long, twisted horns – typically in females and in males. Males stand from at the shoulder, with females at . They are sexually dimorphic, as the females are smaller than the males. The colour of the coat depends on the season – in the winter, it is greyish-brown with white hindquarters and legs, and long, brown hair on the head, neck, and shoulders; in the summer, the coat turns almost completely white or sandy blonde. The addax mainly eats grasses and leaves of any available shrubs, leguminous herbs and bushes. They are well-adapted to exist in their desert habitat, as they can live without water for long periods of time. Addax form herds of five to 20 members, ...

Arabian Oryx
The Arabian oryx (''Oryx leucoryx'') or white oryx is a medium-sized antelope with a distinct shoulder bump, long, straight horns, and a tufted tail. It is a bovid, and the smallest member of the genus ''Oryx'', native to desert and steppe areas of the Arabian Peninsula. The Arabian oryx was extinct in the wild by the early 1970s, but was saved in zoos and private reserves, and was reintroduced into the wild starting in 1980. In 1986, the Arabian oryx was classified as endangered on the IUCN Red List, and in 2011, it was the first animal to revert to vulnerable status after previously being listed as extinct in the wild. It is listed in CITES Appendix I. In 2016, populations were estimated at 1,220 individuals in the wild, including 850 mature individuals, and 6,000–7,000 in captivity worldwide. Etymology The taxonomic name ''Oryx leucoryx'' is from the Greek ' (gazelle or antelope) and ' (white). The Arabian oryx is also called the white oryx in English, ' in Hebrew, and is ...

Gemsbok
The gemsbok or South African oryx (''Oryx gazella'') is a large antelope in the genus ''Oryx''. It is native to the extremely dry, arid regions of Southern Africa; notably, the Kalahari Desert. Some authorities formerly classified the East African oryx, or ''beisa'' oryx, as a subspecies. The gemsbok is depicted on the coat of arms of Namibia, where the current population of the species is estimated at 373,000 individuals. In the town of Oranjemund, resident gemsbok wander freely around the streets, taking advantage of the vegetation in the town, such as the grass in parks, road medians, and browsing on low branches of the many trees. Name The name ''gemsbok'' is from Afrikaans, which itself is from the Dutch word of the same spelling, meaning "male chamois", composed of (“chamois”) + (“buck, male goat”). The Dutch is further from German ("chamois"). Although some superficial similarities in appearance (especially in the facial pattern) are noticed, the chamois and t ...

Scimitar Oryx
The scimitar oryx (''Oryx dammah''), also known as the scimitar-horned oryx and the Sahara oryx, is a ''Oryx'' species that was once widespread across North Africa. In 2000, it was declared extinct in the wild on the IUCN Red List. A captive bred group was released into an acclimation enclosure within the Ouadi Rimé-Ouadi Achim Faunal Reserve in 2016, then reintroduced into the wild. An additional 21 individuals were released into the acclimation enclosure in 2017. The first ones to be relocated were released into the wild in 2016 and have adapted well to their surroundings. In 2017, another herd of 75 scimitar-horned oryxes arrived in an operation led by Chad's Ministry of Environment and Fisheries and the Sahara Conservation Fund. In 2021, 60 new calves were born, bringing the number in the wild to about 400. This particular oryx can survive for months or even years without drinking water. A grazing animal, it derives most of its daily moisture intake from plants. The scimit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fringe-eared Oryx
The fringe-eared oryx (''Oryx callotis'' or ''Oryx beisa callotis''), is a large species or subspecies of oryx antelope native to east Africa. It was originally described as a distinct species by Oldfield Thomas in 1892, but was subsequently re-evaluated as a subspecies of the East African oryx by Richard Lydekker in 1912. Recently, however, analysis using the phylogenetic species concept has led some authors to conclude that it should be returned to full species status. Description Fringe-eared oryxes are relatively muscular antelopes with short, slender legs. Adults are in head-body length, with a tail long, and stand tall at the shoulder. Males are heavier, weighing , compared with for females, but the two sexes are otherwise difficult to distinguish. The hair is fawn-coloured across almost the entire body, with a black stripe down the flanks. There are also black bands on the front and side of the face, and down the throat, while the muzzle is white. There is a shor ...

Common Beisa Oryx
The common beisa oryx (''Oryx beisa beisa''), also known as the beisa oryx, is the nominate subspecies of the East African oryx native to the Horn of Africa and Kenya. It is closely related to the fringe-eared oryx. There are four species of oryx, one of which has two distinct subspecies. Although they are very similar in appearance, they have a number of distinct characteristics that allow identification. Common beisa oryx have fringed ears and black tufts of hair that extend past their ears. However, all species of oryx are compact and muscular, with relative long bodies and broad necks. There are not any marked difference between male and female oryx. The common beisa oryx enjoys feeding on a variety of grass species. They feed during the day, when the plants hold the most water. During the dry season, they feed on poisonous ''Adenium'' plants. Habitat The common beisa oryx once inhabited a large region of northeastern Africa, from Sudan down to Tanzania, but it has been goin ...

East African Oryx
The East African oryx (''Oryx beisa''), also known as the beisa is a species of antelope from East Africa. It has two subspecies: the common beisa oryx (''Oryx beisa beisa'') found in steppe and semidesert throughout the Horn of Africa and north of the Tana River (Kenya), Tana River, and the fringe-eared oryx (''Oryx beisa callotis'') south of the Tana River in southern Kenya and parts of Tanzania. In the past, some Taxonomy (biology), taxonomists considered it a subspecies of the gemsbok (''Oryx gazella''), but they are genetically distinct; the Ploidy#Diploid, diploid chromosome count is 56 for the beisa and 58 for the gemsbok. The species is listed as Endangered by the IUCN. Description The East African oryx stands just over a metre at the shoulder and weight, weighs around . It has a grey coat with a white underside, separated from the grey by a stripe of black, with black stripes where the head attaches to the neck, along the nose, and from the eye to the mouth and on the fo ...

Etosha National Park, Namibia (2826106980)
Etosha National Park is a national park in northwestern Namibia and one of the largest national parks in Africa. It was proclaimed a game reserve in March 1907 in Ordinance 88 by the Governor of German South West Africa, Friedrich von Lindequist. It was designated as ''Wildschutzgebiet'' in 1958, and was elevated to the status of a national park in 1967 by an act of parliament of the Republic of South Africa. It spans an area of and gets its name from the large Etosha pan which is almost entirely within the park. With an area of , the Etosha pan covers 23% of the total area of the national park. The area is home to hundreds of species of mammals, birds and reptiles, including several threatened and endangered species such as the black rhinoceros. The park is located in the Kunene region and shares boundaries with the regions of Oshana, Oshikoto and Otjozondjupa. History Areas north of the Etosha pan were inhabited by Ovambo people, while various Otjiherero-speaking groups ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
