Hints： Kalahari Springbok antelope Africa offload Cheetah Thinly-furred lightly-built

The Kalahari's high levels of rainfall mean food is plentiful year round, one reason why this desert can support more large mammals than any other in the world.
Springbok are the most successful desert antelopes in Africa. With short, thin fur, they can easily offload heat by sweating. The white patterns on their coats help to reflect solar radiation. And they never need to drink. They can extract all the moisture they need from the most meagre desert plants.
But in southern Africa's deserts, there is a lurking challenge. Cheetahs shadow the springbuck herds. They ,too, evolve in the desert. Thinly-furred and lightly-built, everything about them is designed to deal with heat and speed.
