The aardwolf has a similar frame to the hyaena. Its small teeth are weak and set wide apart. Above the aardwolf's anus, it secretes a musky fluid from two glands, and applies a sweet-smelling substance to objects within its home range as a form of communication with other aardwolfs. When an aardwolf gets angry, it lets out a loud roar and raises its long dorsal mane into a crest. Their young are born in burrows which are usually skillfully enlarged by the parents. Males help in rearing the young by guarding the den against jackals, which are probably their greatest natural enemy.
They are very timid animals, and are primarily nocturnal, although they may be active during the late afternoon if termites are available at that time. They often get caught in the beam of car headlights: many aardwolf are killed accidentally by cars. Termites are the aardwolf's main dish and it is guided to them by its sharp hearing and keen nose. do not drink surface water, as they get all of their water requirements from termites. They have been known, however, to drink water during cold spells when termites are not available.
