How Strong Is a Grizzly Bear?
Grizzly bears are estimated to be 2.5 to 5 times as strong as an average human. Grizzly bear jaws are powerful enough to bite through a cast iron skillet and to crush a bowling bowl.
In one test, a 700 pound dumpster that required two people to tip it over could be rolled around like a beach ball by a single grizzly bear. Grizzly bears can sprint at up to 40 miles per hour.
A grizzly bear can weigh up to 800 pounds and live 20 to 30 years. These bears primarily eat plants, berries and tubers. They also eat grubs, fish and occasionally meat.
