Grizzly Bear vs Lion: Why the Lion Needs a Perfect Fight and the Grizzly Just Has to Show Up

A grizzly bear versus a lion: who wins? My answer is the grizzly bear, because the lion needs a perfect fight and the grizzly just has to show up.

The grizzly bear's numbers get more absurd the closer you look

The grizzly bear is one of those animals where the more you look at the numbers, the more absurd they get. It weighs up to 800 lb and has a bite force of 1,200 PSI, nearly double the lion's. Its claws are 4 inches long, they don't retract, and they're designed for tearing through anything. A single paw swipe from a full-grown grizzly can break a lion's spine outright.

Grizzlies also run solo their entire lives. They hunt alone and survive conditions that would end most predators. Nobody does the hunting for a grizzly. It just handles things itself.

The lion's only real path is a clean neck bite early

The lion isn't a joke, though. It's faster than 50 mph, against the grizzly's 35. Its neck bite is one of the most precise killing strikes in the animal kingdom, evolved specifically to suffocate large prey quickly. Male lions have taken down Cape buffalo and held their own against hippos.

In the right circumstances, with the right first strike, a lion can end a fight before the size difference becomes relevant. That's the lion's only real path here: land a clean neck bite early and make it count before the grizzly's weight and power take over.

Why the grizzly bear wins a sustained brawl

Once this becomes a sustained brawl, the grizzly's strength, its 1,200 PSI bite and those 4 inch claws just overwhelm the lion's ability to stay in the fight. "Speed doesn't matter much when something twice your weight is sitting on you."

"The lion needs a perfect fight. The grizzly, it's just got to show up." The grizzly bear wins.

Could a lion's first strike ever be enough against a grizzly bear?
