Grant's gazelle (Nanger granti) is a relatively large species of gazelle antelope, distributed from northern Tanzania to South Sudan and Ethiopia, and from the Kenyan coast to Lake Victoria. Its Swahili name is swala granti. It was named for a 19th-century British explorer, James Grant. Taxonomy and genetics Grant's gazelle is genetically related to Soemmerring's gazelle (N. soemmerringii) and Thomson's gazelle (Eudorcas thomsonii) with Soemmering's gazelle being the closer relative. Grant's gazelle shows high genetic variation among its populations, although there is no geographic isolation. The differentiation of the species may have evolved during repeated expansion and contraction of arid habitats during the late Pleistocene era in which populations were possibly isolated. Grant's gazelle was formerly considered a member of the genus Gazella within the subgenus Nanger before Nanger was elevated to genus status. In 2021, the American Society of Mammalogists granted full species status to Bright's gazelle (Nanger notatus) and the Peter's gazelle (Nanger petersii). Subspecies Listed alphabetically. N. g. granti (Brooke, 1872) – southern Grant's gazelle N. g. lacuum (Neumann, 1906) – northern Grant's gazelle N. g. robertsi (Thomas, 1903) – Robert's gazelle Description The Grant's gazelle stands at the shoulder. The females weigh from and males from . Its coat is a beige orange on the back with a white belly. The Grant's gazelle looks similar to a Thomson's gazelle, except it is much larger and has lyre-shaped horns which are stout at the base, clearly ringed, and measuring long. A useful field mark is the white on the rump that extends over the top of the tail in Grant's but not Thomson's gazelles. The subspecies are segregated by different morphological characters, such as horn shape and slight differences in coat colour. These differences are not indicative of ecological separation as with some species. Ecology and behaviour The Grant's gazelle is found in East Africa and lives in open grass plains and is frequently found in shrublands; it avoids areas with high grass where the visibility of predators is compromised. They also occur in semiarid areas and are relatively well adapted to dry areas, relying on more browse or leafy material during dry seasons to supplement their intake of water. They are sometimes migratory, but do not travel along with most of the other ungulates, such as Thomson's gazelles, zebras, and wildebeest, which are more water dependent. They can subsist on vegetation in waterless, semiarid areas, where
