The range of the goitred gazelle extends across the Asian deserts to China, though its population is greatly reduced in numbers. The dorcas gazelle also ranges into North Africa. bilkis now extinct), and the dorcas gazelle ( G. saudiya now extinct in the wild), the Queen of Sheba’s gazelle ( G. arabica now extinct), the Saudi gazelle ( G. gazella), the goitred, or sand, gazelle ( G. The Arabian Peninsula is the centre of diversity of the revised genus Gazella, with six species: the mountain gazelle ( G. In the revised classification, Gazella contains ten species-three exclusively African, five exclusively Asian, and one shared by both continents. The Gazella genus as traditionally defined includes eight species that occur only in Africa, five that occur only in Asia, and one species that occurs both in Africa and Asia. The three largest species-the dama gazelle, Grant’s gazelle, and Soemmering’s gazelle-are placed in the genus Nanger (formerly considered a subgenus), and three of the smaller species- Thomson’s gazelle, the red-fronted gazelle, and the Mongalla gazelle-have become the genus Eudorcas. Accordingly, six species, all African, have been removed from Gazella by some authorities and placed in two different genera. However, specialists in the taxonomy of the gazelle tribe (Antilopini), using genetic techniques for studying phylogenetic relationships, now believe that gazelles stem from not one but several different ancestors. The genus Gazella was traditionally considered to contain 14 species. Where can you find a capybara? How many cervical vertebrae do giraffes have? Test your knowledge of mammals by taking this quiz.
If all else fails, they can cool down by rapid nasal panting. Gazelles seek shade and avoid activity in the hottest weather by feeding at night and early morning when plants contain the most moisture. They can tolerate an increase in their core temperature by as much as 5 ☌ (9 ☏). Their coats are light-coloured and reflective. Their urine is concentrated, and, before excretion, moisture is extracted from their fecal pellets. They have narrow jaws and incisor rows for highly selective feeding on the most nutritious growth. They can extract water from the plants they browse without having to drink. Gazelles have adapted to inhabit waterless steppe, subdesert, and even desert. Most gazelles are placed in the genus Gazella, family Bovidae (order Artiodactyla). They inhabit the arid lands of Asia from China to the Arabian Peninsula, North Africa from the Saharan deserts to the sub-Saharan Sahel, and northeast Africa from the Horn of Africa to Tanzania. Most gazelles are tan-coloured, with white underparts and rump patch, a dark side stripe, and contrasting facial markings. Gazelle, any of several fleet, medium-sized antelopes with slender, evenly developed limbs, level backs, and long necks.
