Fact: The jaws of a wolf apply 1,000 to 1,500 pounds of pressure per square inch, enough to crush bones. By comparison, a German shepherd has a biting pressure of 750 pounds per square inch, and a human can muster about 300 pounds per square inch of pressure.
Fact: Adult female wolves in northern Minnesota weigh 50 to 85 pounds; males are 70 to 110 pounds. (Wolves are larger in the northwestern U.S., Canada and Alaska, where males can reach 130 pounds.)
Fact: Wolves travel long distances by trotting at about 5 miles per hour, but they can sprint at 36 to 38 miles per hour while chasing prey.
Fact: Wolves are opportunistic: They'll eat road kill, rabbits and anything else they come across, including domestic animals. Since last summer, they've killed 165 cattle, 16 sheep, 17 farm-raised deer, six goats, four horses, a donkey, a llama and 364 farm-raised turkeys.
