Its ears are very large as you can see and on some are about half as long as their bodies. Those large ears are not just ornamental, though, for they help to regulate the body's heat.
Fennec foxes make their homes in the deserts of North Africa and Asia. They live in dens dug out of the sand ideally at the base of a stable sand dune, but they have also dug dens in open areas or near the shelter of plants. There are usually about 10 to a den, and sometimes the dens connect with others.
They have long, thick hair even on their feet. This helps protect them from the extreme temperatures of the desert and keeps their feet from getting too hot in the sand. They are omnivores and are also nocturnal. Rodents are a favorite food, but they also eat plants, insects and fruit. Some even eat eggs, birds and rabbits. They can also go along time without water.
One interesting fact I found on Wikipedia is that they can jump 2 ft. high and 4 ft. forward! This enables them to catch their prey or escape from predators. Fennec foxes usually mate for life and a litter will consist of 1 to 3 babies called kits. Their lifespan is usually about 10 years.
