Living underground, mole1 rats are sheltered from the Kalahari's worst extremes of temperature. We think of deserts as hot places. But nightly temperatures can fall well below zero.

At dawn, meerkats need to soak up the warmth of the rising sun to get fully2 active. The temperature in the Kalahari steadily3 climbs as high as 70 Celsius4 on the ground. Meerkats can only tolerate short bursts of activity in the morning and evening. This means they need to be very efficient at gathering5 food. So they quarter their territory, traveling several kilometers a day.

Tasty beetles6 and scorpions7 are common in this grassy8 desert. But finding them means spending a lot of time with your head in the sand. So meerkats are very vulnerable to predators9. To protect the group, young males take turns keeping watch. This frees the others up to keep hunting. Scorpions have a lethal10 sting, but meerkats are fast as lightning.

The Kalahari's high levels of rainfall mean food is plentiful11 year round, one reason why this desert can support more large mammals than any other in the world.

Springbok are the most successful desert antelopes12 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 lurking13 challenge. Cheetahs14 shadow the springbuck herds15. They ,too, evolve in the desert. Thinly-furred and lightly-built, everything about them is designed to deal with heat and speed.
