No they don't attack each other.They are in a whole family.If they do attack each other,that means they are not friends or a member from the family. Incorrect, there are sharks that attack other sharks, whether within a species or between species, it does happen.
sharks actually attack men more than women because the men are always surfing. the women appear to be attacked more because of hollywood's movies. hollywood always makes women the victims because they are supposed to be more "delicate".
