Grey Wolf

Perhaps the only creature tough enough to match Liam Neeson on a bad day, the grey wolf is tough on its own and all-but inescapable when encountered in a pack. It can handle temperatures at -40 degrees and can move at almost 40 mph. Its bite can be as strong as 1,500 pounds per square inch. And you can bet that, if you encounter a whole pack, you won’t be getting bit just once.
