The term antelope is used to refer to many species of even-toed ruminant that are indigenous to various regions in Africa and Eurasia.
The klipspringer is a small antelope found in eastern and southern Africa. The sole member of its genus and subfamily/tribe, the klipspringer was first described by German zoologist Eberhard August Wilhelm von Zimmermann in 1783. The klipspringer is a small, sturdy antelope; it reaches 43–60 centimetres at the shoulder and weighs from 8 to 18 kilograms. The coat of the klipspringer, yellowish gray to reddish brown, acts as an efficient camouflage in its rocky habitat. Unlike most other antelopes, the klipspringer has a thick and coarse coat with hollow, brittle hairs. The horns, short and spiky, typically measure 7.5–9 cm.
The Zanzibar red colobus is a species of red colobus monkey endemic to Unguja, the main island of the Zanzibar Archipelago, off the coast of Tanzania. It is also known as Kirk's red colobus after Sir John Kirk, the British Resident of Zanzibar who first brought it to the attention of zoological science. It is now classified as an endangered species and in the mid-1990s was adopted as the flagship species for conservation in Zanzibar. The population is still decreasing, and conservationists are attempting to work with the local government to devise a proper, effective strategy to protect the population and habitat. Challenges include the species' habitat, which is limited to the archipelago. The species has been reclassified three times; it was previously in the genus Colobus, then in the genus Procolobus, and later in the genus Piliocolobus.
A dik-dik is the name for any of four species of small antelope in the genus Madoqua that live in the bushlands of eastern and southern Africa.
The addax, 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 55 to 80 cm in females and 70 to 85 cm in males. Males stand from 105 to 115 cm at the shoulder, with females at 95 to 110 cm. 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 sitatunga or marshbuck is a swamp-dwelling antelope found throughout central Africa, centering on the Democratic Republic of the Congo, the Republic of the Congo, Cameroon, parts of Southern Sudan, Equatorial Guinea, Burundi, Ghana, Botswana, Rwanda, Zambia, Gabon, the Central African Republic, Tanzania, Uganda and Kenya. The sitatunga is confined to swampy and marshy habitats. Here they occur in tall and dense vegetation as well as seasonal swamps, marshy clearings in forests, riparian thickets and mangrove swamps.
The common eland, also known as the southern eland or eland antelope, is a savannah and plains antelope found in East and Southern Africa. It is a species of the family Bovidae and genus Taurotragus. An adult male is around 1.6 metres (5') tall at the shoulder and can weigh up to 942 kg (2,077 lb) with an average of 500–600 kg (1,100–1,300 lb), 340–445 kg (750–981 lb) for females). It is the second largest antelope in the world, being slightly smaller on average than the giant eland. It was scientifically described by Peter Simon Pallas in 1766.
The royal antelope is a West African antelope, recognized as the world's smallest antelope. It was first described by Swedish zoologist Carl Linnaeus in 1758. It stands up to merely 25 centimetres (10 in) at the shoulder and weighs 2.5–3 kilograms (5.5–6.6 lb). A characteristic feature is the long and slender legs, with the hindlegs twice as long as the forelegs. Horns are possessed only by males; the short, smooth, spiky horns measure 2.5–3 centimetres (1.0–1.2 in) and bend backward. The soft coat is reddish to golden brown, in sharp contrast with the white ventral parts. In comparison to Bates's pygmy antelope, the royal antelope has a longer muzzle, broader lips, a smaller mouth and smaller cheek muscles.
The blackbuck, also known as the Indian antelope, is an antelope native to India and Nepal. It inhabits grassy plains and lightly forested areas with perennial water sources. It stands up to 74 to 84 cm high at the shoulder. Males weigh 20–57 kg (44–126 lb), with an average of 38 kg (84 lb). Females are lighter, weighing 20–33 kg (44–73 lb) or 27 kg (60 lb) on average. Males have 35–75 cm (14–30 in) long, ringed horns, though females may develop horns as well. The white fur on the chin and around the eyes is in sharp contrast with the black stripes on the face. The coats of males show a two-tone colouration; while the upper parts and outsides of the legs are dark brown to black, the underparts and the insides of the legs are white. Females and juveniles are yellowish fawn to tan. The blackbuck is the sole living member of the genus Antilope and was scientifically described by Carl Linnaeus in 1758. Two subspecies are recognized.
The Antilopines are even-toed ungulates belong to the family Bovidae. The members of Antilopini are often referred to as true antelopes, and are usually classified as the only living representatives of the Antilopinae. 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 saigas and Tibetan antelopes are related to true antelopes (Antilopinae) and sheep and goats (Caprinae), but are often placed in their own subfamily, Saiginae. These animals inhabit much of central and western Asia. The dwarf antelopes are sometimes placed in a separate subfamily, Neotraginae, and live entirely in sub-Saharan Africa. The Antilopinae are a subfamily of Bovidae that roam the East African savannas and deserts and they have acclimated to possess wider insertion muscles to enable them to avoid predators in the open savanna.
The bohor reedbuck is an antelope native to central Africa. The animal is placed under the genus Redunca and in the family Bovidae. It was first described by German zoologist and botanist Peter Simon Pallas in 1767. The bohor reedbuck has five subspecies. The head-and-body length of this medium-sized antelope is typically between 100–135 cm (39–53 in). Males reach approximately 75–89 cm (30–35 in) at the shoulder, while females reach 69–76 cm (27–30 in). Males typically weigh 43–65 kg (95–143 lb) and females 35–45 kg (77–99 lb). This sturdily built antelope has a yellow to grayish brown coat. Only the males possess horns which measure about 25–35 cm (9.8–13.8 in) long.
The oribi is a small antelope found in eastern, southern and western Africa. The sole member of its genus, it was described by the German zoologist Eberhard August Wilhelm von Zimmermann in 1783. Eight subspecies are identified. The oribi reaches nearly 50–67 centimetres (20–26 in) at the shoulder and weighs 12–22 kilograms (26–49 lb). It possesses a slightly raised back, and long neck and limbs. The glossy, yellowish to rufous brown coat contrasts with the white chin, throat, underparts and rump. Only males possess horns; the thin, straight horns, 8–18 centimetres (3.1–7.1 in) long, are smooth at the tips and ringed at the base.
The Suni is a small antelope. It occurs in dense underbrush from central Kenya to KwaZulu-Natal in South Africa.
The dibatag, or Clarke's gazelle, is a medium-sized slender antelope native to Ethiopia and Somalia. Though not a true gazelle, it is similarly marked, with long legs and neck. It is often confused with the gerenuk due to their striking resemblance. The typical head-and-body length is about 103 to 117 cm. They stand up to about 80 to 90 cm. Male dibatag weigh between 20 and 35 kg, whereas females range from 22 and 29 kg. The length of the curved horns, present only on males, is typically between 10 and 25 cm. The upper parts are gray to fawn, while the dorsal and lateral areas are cinnamon to rufous. The underparts, rump and the insides of the legs are all white. While markings are visible on the face, there are none on the flanks or the buttocks.
The Patagonian mara is a relatively large rodent in the mara genus Dolichotis. It is also known as the Patagonian cavy, Patagonian hare, or dillaby. This herbivorous, somewhat rabbit-like animal is found in open and semiopen habitats in Argentina, including large parts of Patagonia. A population has also been recorded in the northern United Arab Emirates, possibly as a result of escaped pets or captive animals. It is monogamous, but often breeds in warrens shared by several pairs.
The red-flanked duiker is a species of small antelope found in western and central Africa in countries as far apart as Senegal and Sudan. Red-flanked duikers grow to almost 15 in (35 cm) in height and weigh up to 31 lb (14 kg). They have russet coats, with greyish-black legs and backs, and white underbellies. They feed on leaves, fallen fruits, seeds and flowers, and sometimes twigs and shoots. The adults are territorial, living in savannah and lightly wooded habitats, and the females usually produce a single offspring each year. They have lifespans of ten to fifteen years in captivity.
The steenbok is a common small antelope of southern and eastern Africa. It is sometimes known as the steinbuck or steinbok.
Salt's dik-dik is a small antelope found in semidesert, bushland, and thickets in the Horn of Africa, but marginally also in northern Kenya and eastern Sudan. It is named after Henry Salt, who was the first European to acknowledge the species in Abyssinia in the early 19th century.
Günther's dik-dik is a small antelope found in arid zones of East Africa.
The preorbital gland is a paired exocrine gland found in many species of hoofed animals, which is homologous to the lacrimal gland found in humans. These glands are trenchlike slits of dark blue to black, nearly bare skin extending from the medial canthus of each eye. They are lined by a combination of sebaceous and sudoriferous glands, and they produce secretions which contain pheromones and other semiochemical compounds. Ungulates frequently deposit these secretions on twigs and grass as a means of communication with other animals.
