1. Grizzly Bear
The grizzly’s weapons are formidable: They are huge (up to 1,200 pounds, but typically more like 500 to 800), strong (capable of lifting nearly their body weight or more), and powerful, with a bite that could crush a bowling ball. And there’s this: Since 1895, there have been 15 reported cases of grizzly bears decapitating moose with a single paw swipe.
