They have an eerie howling that can be heard for miles and that strikes fear in the listener. To the wolf this is simply a social activity of the pack—a form of communication. A wolf who has become separated during a hunt may climb a ridge and howl to attract other members of the pack. Or howling may be used to define its territory.
The individual wolf has powerful jaws and the teeth of a carnivore; canines designed to grab and hold and carnassial designed to cut meat.

Three to ten wolves, depending on area pack size, would be a formidable defense against any other top their predator, excepting man.
