The 'udhrut (plural 'adharit) normally looks like a wolf, but it can change its shape into that of a dog, cat or any other animal, or it can resemble a stone, or even a man or woman.
According to Yemeni folklore, the 'udhrut is attracted by the blood of the dead and is known to appear at the scene of a murder. It will suddenly materialise before a person, bark or growl at him and then vanish. There is apparently no way to exorcise the 'udhrut, whose only purpose seems to be to frighten humans. They apparently do no other harm.
