We are no strangers to the mighty grizzly bear. The strength of these critters is mind blowing. With a weight of nearly 700 lbs, and a top speed of 35mph, this is one predator that is not to be messed with. Much like an ant, who are able to lift 5,000 times their own body weight, watch as a griz lifts a 1-ton bison carcass in Yellowstone Park.
