Gazella Deperdita
A gazelle is one of many antelope species in the genus ''Gazella'' . This article also deals with the 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 are able to run at bursts as high as or run at a sustained speed of . 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 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. Currentl ...

Indian Subcontinent
The Indian subcontinent is a list of the physiographic regions of the world, physiographical region in United Nations geoscheme for Asia#Southern Asia, Southern Asia. It is situated on the Indian Plate, projecting southwards into the Indian Ocean from the Himalayas. Geopolitically, it includes the countries of Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, and Sri Lanka."Indian subcontinent". ''Oxford Dictionary of English, New Oxford Dictionary of English'' () New York: Oxford University Press, 2001; p. 929: "the part of Asia south of the Himalayas which forms a peninsula extending into the Indian Ocean, between the Arabian Sea and the Bay of Bengal. Historically forming the whole territory of Greater India, the region is now divided into three countries named Bangladesh, India and Pakistan." The terms ''Indian subcontinent'' and ''South Asia'' are often used interchangeably to denote the region, although the geopolitical term of South Asia frequently includes Afghanist ...

Lion
The lion (''Panthera leo'') is a large Felidae, cat of the genus ''Panthera'' native to Africa and India. It has a muscular, broad-chested body; short, rounded head; round ears; and a hairy tuft at the end of its tail. It is sexually dimorphic; adult male lions are larger than females and have a prominent mane. It is a social species, forming groups called ''prides''. A lion's pride consists of a few adult males, related females, and cubs. Groups of female lions usually hunt together, preying mostly on large ungulates. The lion is an apex predator, apex and keystone predator; although some lions scavenge when opportunities occur and have been known to hunt Human, humans, lions typically don't actively seek out and prey on humans. The lion inhabits grasslands, savannas and shrublands. It is usually more diurnality, diurnal than other wild cats, but when persecuted, it adapts to being active nocturnality, at night and crepuscular, at twilight. During the Neolithic period, the li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cheetah
The cheetah (''Acinonyx jubatus'') is a large cat native to Africa and central Iran. It is the fastest land animal, estimated to be capable of running at with the fastest reliably recorded speeds being , and as such has evolved specialized adaptations for speed, including a light build, long thin legs and a long tail. It typically reaches at the shoulder, and the head-and-body length is between . Adults weigh between . Its head is small and rounded, with a short snout and black tear-like facial streaks. The coat is typically tawny to creamy white or pale buff and is mostly covered with evenly spaced, solid black spots. Four subspecies are recognised. The cheetah lives in three main social groups: females and their cubs, male "coalitions", and solitary males. While females lead a nomadic life searching for prey in large home ranges, males are more sedentary and instead establish much smaller territories in areas with plentiful prey and access to females. The cheetah is act ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stotting
Stotting (also called pronking or pronging) is a behavior of quadrupeds, particularly gazelles, in which they spring into the air, lifting all four feet off the ground simultaneously. Usually, the legs are held in a relatively stiff position. Many explanations of stotting have been proposed, though for several of them there is little evidence either for or against. The question of why prey animals stot has been investigated by evolutionary biologists including John Maynard Smith, C. D. Fitzgibbon, and Tim Caro; all of them conclude that the most likely explanation given the available evidence is that it is an honest signal to predators that the stotting animal would be difficult to catch. Such a signal is called "honest" as it is not deceptive in any way, and would benefit both predator and prey; the predator as it avoids a costly and unproductive chase, and the prey as it does not get chased. Etymology ''Stot'' is a common Scots and Northern English verb meaning "bounce" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomson's Gazelle
Thomson's gazelle (''Eudorcas thomsonii'') 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. Thomson's gazelles can be found in numbers exceeding 200,000 in Africa and are recognized as the most common type of gazelle in East Africa. A small fast antelope, the Thomson's gazelle is claimed to have top speeds up to . It is the fourth-fastest land animal, after the cheetah (its main predator), pronghorn, and springbok. Taxonomy and etymology The current scientific name of Thomson's gazelle is ''Eudorcas thomsonii''. It is a member of the genus ''Eudorcas'' and is classified under the family Bovidae. Thomson's gazelle was first described by British zoologist Albert Günther in 1884. The rel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Springbok
The springbok (''Antidorcas marsupialis'') is a medium-sized antelope found mainly in south and southwest Africa. The sole member of the genus ''Antidorcas'', this bovid was first described by the German zoologist Eberhard August Wilhelm von Zimmermann in 1780. Three subspecies are identified. A slender, long-legged antelope, the springbok reaches at the shoulder and weighs between . Both sexes have a pair of black, long horns that curve backwards. The springbok is characterised by a white face, a dark stripe running from the eyes to the mouth, a light-brown coat marked by a reddish-brown stripe that runs from the upper fore leg to the buttocks across the flanks like the Thomson's gazelle, and a white rump flap. Active mainly at dawn and dusk, springbok form harems (mixed-sex herds). In earlier times, springbok of the Kalahari desert and Karoo migrated in large numbers across the countryside, a practice known as ''trekbokking''. A feature, peculiar but not unique, to t ...

Blackbuck
The blackbuck (''Antilope cervicapra''), 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 high at the shoulder. Males weigh , with an average of . Females are lighter, weighing or on average. Males have 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 blackbuck is active mainly during the day. It forms three type of small groups, female, male, and bachelor h ...

Mongolian Gazelle
The Mongolian gazelle (''Procapra gutturosa''), or dzeren (russian: Дзерэн), is a medium-sized antelope native to the semiarid Central Asian steppes of Mongolia, as well as some parts of Siberia and China. The name ''dzeren'' is Russian misinterpretation of the Mongolian language name of ''zeer'' ( mn, Зээр) or Buryat zeeren ( Buryat: Зээрэн). Description In the summer, its coat is light brown with pinkish tones, becoming longer and paler during the winter. It also has a distinctive heart-shaped white patch on its rump area, divided by a median line of darker color. The male has lyre-shaped horns which curl backwards from the forehead. It is an extremely fast runner and good swimmer. In the winter, they are mostly diurnal, but in the summer, they are active shortly after sunrise and before sunset. They tend to travel a lot, and migrations takes place in spring and autumn, but the distance and direction vary depending on the weather and food availability. Behav ...

Goa (antelope)
The goa (''Procapra picticaudata''), also known as the Tibetan gazelle, is a species of antelope that inhabits the Tibetan plateau. Description The goa is a relatively small antelope, with slender and graceful bodies. Both males and females stand tall at the shoulder, measure in head-body length and weigh . Males have long, tapering, ridged horns, reaching lengths of . The horns are positioned close together on the forehead, and rise more or less vertically until they suddenly diverge towards the tips. Females have no horns, and neither sex has distinct facial markings. The goa is grayish brown over most of its body, with its summer coat being noticeably greyer in colour than its winter one. It has a short, black-tipped tail in the center of its heart-shaped white rump patches. Its fur lacks an undercoat, consisting of long guard hairs only, and is notably thicker in winter. It appears to have excellent senses, including keen eyesight and hearing. Its thin and long legs enh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Threatened
Threatened species are any species (including animals, plants and fungi) which are vulnerable to endangerment in the near future. Species that are threatened are sometimes characterised by the population dynamics measure of ''critical depensation'', a mathematical measure of biomass related to population growth rate. This quantitative metric is one method of evaluating the degree of endangerment. IUCN definition The International Union for Conservation of Nature (IUCN) is the foremost authority on threatened species, and treats threatened species not as a single category, but as a group of three categories, depending on the degree to which they are threatened: *Vulnerable species *Endangered species * Critically endangered species Less-than-threatened categories are near threatened, least concern, and the no longer assigned category of conservation dependent. Species which have not been evaluated (NE), or do not have sufficient data (data deficient) also are not considered "t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Queen Of Sheba's Gazelle
The Queen of Sheba's gazelle or Yemen gazelle (''Gazella bilkis''), is an extinct species of gazelle. It was sometimes regarded as a subspecies of the Arabian gazelle, which is no longer a valid species. It was found on the mountains and hillsides in Yemen, but none have been sighted since 1951, when five specimens were collected in mountains near Ta'izz, where it was reportedly common at the time. Surveys in the area of their former occurrence have failed to find any sign of its presence.Mallon, D.P. and Al-Safadi, M. 2001.Yemen. In: D.P. Mallon and S.C. Kingswood (compilers). 2001. Antelopes.
