An adult male Thompson's Gazelle. This species is much smaller than the Grant's Gazelle. It has the characteristic diagonal black stripe on the body. Sometimes the female has horns, but their's are very thin and weak. The Tommy does not have to go to a watering site--dangerous because of predators. It can get enough moisture from the grasses that it eats. Also, a watering site is not where this species can best use its main defense--speed afoot. [Masai Mara, Kenya].
