Grant’s gazelles resemble Thomson’s gazelles, and the two species are often seen together. They are similarly colored and marked, but Grant’s are noticeably larger than Thomson’s and easily distinguished by the broad white patch on the rump that extends upward, beyond the tail and onto the back. The white patch on the Thomson’s gazelle stops at the tail. Some varieties of Grant’s have a black stripe on each side of the body like the Thomson’s gazelle; in others the stripe is very light or absent. A black stripe runs down the thigh.
