Grant's gazelle (Nanger granti) is a species of gazelle distributed from northern Tanzania to southern Sudan and Ethiopia, and from the Kenyan coast to Lake Victoria. Grant's gazelle shows high genetic variation among its populations, though there is no geographic isolation.
The Grant's gazelle stands 30–37 in at the shoulder. 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 has lyre-shaped horns which are stout at the base, clearly ringed, and measuring 18–32 in long. It is distinguished by a white rump that extends above the base of the tail.
Thomson's gazelle (Eudorcas thomsonii) is one of the best-known gazelles. It is named after explorer Joseph Thomson and is sometimes referred to as a "tommie". Thomson's gazelles can be found in numbers exceeding 550,000 in Africa and are recognized as the most common type of gazelle in East Africa.
Thomson's gazelles are 22 to 32 in tall. They have light brown coats with white underparts and distinctive black stripes on the sides. Their horns are long and pointed with slight curvature. The white patch on their rumps extends to underneath the tail, but no further.
