Moreover, in order to walk on the hot sand, a Fennec foxs feet are covered with thick fur. N

34、ot only that, the feet also help in digging, as this animal lives under the ground.Habitat and LifestyleThe habitat of this animal is mainly in the Sahara Desert, and also in other parts of North Africa. The Fennec fox is usually active during the night. This character helps it deal successfully wit

35、h the extreme heat in the desert.As an extremely social animal, it often lives in groups of ten and each group has its own land.

36、mnivore (杂食动物). While it can survive on plants, it also needs other items such as insects, rabbits, birds and eggs.
