Wolves have 42 teeth, and their jaws can crush caribou, elk, white tail deer, and moose bones. Their jaws pack 1,500 pounds of pressure per square inch, two times stronger than that of a German Shepherd.
Wolves howl to communicate with other wolves. Some howls warn the pack of danger ahead, while other sounds—such as barking, growling, whimpering, and whining—have different meanings.
