Some 30,000 zebras and 15,000 buffaloes bustle about in the vast savannah, and 5,000 giraffes and 8,000 elephants keep them company.
The striking pattern of stripes in savannah zebras is different in each animal. Therefore the members of a family can recognise each other by their stripes.
Although the stripes are extremely visible at close range, they make a good camouflage from far away and provide protection against predators. Lions in particular like to prey on zebras.
The group behaviour of zebras is quite fascinating. They live in small family units of up to 20 members, led by a stallion.
The families stay together for many years. If an animal gets lost, the group can spend days looking for it.
Blue wildebeests (also called gnu) wear dark stripes on the throat and on the sides.
They live all over in the open savannah of Southern Africa.
They are social creatures and live in groups of 20 to 40 animals, sometimes in larger herds, the members of which are usually cows and calves, led by a bull.
And there are herds consisting exclusively of bachelor bulls.
