Tsessebe can be easily distinguished from other antilopes by having bluish-black faces, forelimbs, thighs and tail tufts.
Both sexes have horns, but females usually have shorter horns which are less thick at the base.
They prefer grassland habitats.
Tsessebe are the fastest antelope in Africa and can run at speeds over 90 km/h.
