Thomson's Gazelle of East Africa is similar to the Red-fronted Gazelle of West Africa, Grant's Gazelle of East Africa and the
Springbok of South Africa, but the latter two have white on their rump above the tail as well as below. All are fast (up to 80 km/hr)
small antelopes and all but Grant's have the thick black bar on their side to make them look less well-fed to predators.
The adult male has long, ridged horns (above left); the female and juvenile male have short straight horns (top right) or no horns.
They live in herds on grasslands/Savannah.
