The fennec fox is the smallest fox in the world. It weighs about as much as a bag of sugar. It lives in the Sahara Desert in North Africa, one of the hottest places on Earth.
The first thing most people notice about the fennec fox is its enormous ears. They can be as long as 15 centimetres, which is huge for such a small animal. The ears do two important jobs. First, they let heat escape from the fox's body, helping it to stay cool. Second, they are so sensitive that the fox can hear insects moving under the sand.
The fennec fox has other ways to survive in the desert, too. Thick fur on the bottoms of its feet protects it from the burning sand. During the hottest part of the day, it rests in a cool burrow underground. It comes out to hunt at night, when the air is cooler.
Water is hard to find in the desert, but the fennec fox can go a long time without drinking. It gets most of the water it needs from the food it eats, such as insects, plants and small animals.
