These are short black-tailed antelopes known to be the fastest of their kind. They are found in the Savannah and the floodplains of Sudan, Chad, Kenya, Tanzania and Southern Africa. They are famous for their solitary sentinel position. The animal stands for hours on a termite mound surveying the surrounding territory in this position. The Topi, Impalas and the Giraffes are the only animals that are not found on the Ngorongoro Crater. They have a rusty-red colour coat. Their legs and chest are black in colour with a black strip running from the forehead to the tip of their nose.
