Polar bear Vs Grizzly bear, who would win a fight between two of the strongest predators?

Let’s imagine two of the strongest animals, the grizzly bear and polar bear going head-to-head. That would be one of the deadliest battles of the animal kingdom. Both Grizzlies and polar bears are large, muscular, and territorial and are strong enough to take on a fight with any potential enemy.

So, what happens in the fight between these two beasts, who is truly the strongest?

Size and Appearance

Male polar bears weigh 350 to 700 kg and have a total length of 7 ft 10 inches to 9 ft 10 inches. Females are nearly half the size of males, weighing between 150 to 250 kg and standing 5 ft 11 inches to 7 ft 10 inches tall. A polar bear's shoulder height ranges from 4 ft 0 inches to 5 ft 3 inches.

A male shot near Kotzebue Sound in northeastern Alaska in 1960 was said to be the world's largest polar bear, weighing 1,002 kg. This specimen stood 11 feet 1 inch tall on its hind legs when mounted.

Compared with its closest relative, the brown bear, the polar bear has a more elongated body build and a longer skull and nose.

On the other hand, our opponent,

Adult female grizzlies weigh 130–180 kilograms on average, while adult males weigh 180–360 kilograms on average. This subspecies' average total length is 198 centimeters, with a shoulder height of 102 centimeters and a hindfoot length of 28 centimeters. However, one study indicated that an inland male grizzly's average weight was around 272 kilograms, whereas a coastal male’s average weight was around 408.

Grizzly Bear

Because it spends so much of the year near the water, the polar bear is classified as a marine animal. It is, however, the only extant marine mammal with robust, big limbs and feet that allow it to walk and run for kilometers on land. The annual sea ice that covers the waters above the continental shelf and the Arctic inter-island archipelagos is its favored habitat. In comparison to the deep waters of the high Arctic, these areas, known as the "Arctic ring of life," have high biological productivity.

The grizzly bear, commonly known as the North American brown bear or just grizzly, is a North American brown bear population or subspecies.

In addition to the mainland grizzly, other morphological forms of brown bears in North America are sometimes identified as grizzly bears. The Kodiak bear and the peninsular grizzly are two viable populations, while the California grizzly, Mexican grizzly, and Ungava-Labrador grizzly are all extinct. Grizzly bears near the coast are larger on average, while inland grizzlies are smaller.

Woodlands, woods, alpine meadows, and plains are all home to grizzly bears. They enjoy riparian areas near rivers and streams in many environments.


The polar bear is the most carnivorous member of the bear family, and it eats ringed and bearded seals across the majority of its range. Adult male bearded seals, weighing between 350 and 500 kilograms, are too enormous for a female bear to overpower, making them only suitable prey for mature male bears. Large males will also occasionally attempt to seek and kill even larger prey. Although it is rarely done, it is capable of killing an adult walrus. A walrus can weigh up to 2,000 kg and has an average adult mass of 600 to 1,500 kg, making it more than twice the size of a bear.

Although grizzlies belong to the Carnivora order and have a carnivore digestive system, they are usually omnivores, eating both plants and animals. When large mammals such as moose, elk, caribou, white-tailed deer, mule deer, bighorn sheep, bison, and even black bears are accessible, they have been known to prey on them, however, they are more inclined to take calves and injured individuals rather than healthy adults. Grizzly bears eat salmon, trout, and bass, and those who have access to a more protein-rich diet in coastal locations may grow larger than those who live inland. Grizzly bears are also quick to scavenge food or carcasses abandoned by other animals. Grizzly bears will eat birds and their eggs, as well as spawning salmon, and will congregate in huge numbers at fishing spots.

Polar Bear vs Grizzly Bear - Final Thoughts

Now let’s see who will win the battle between these beasts.

Many people are curious as to who will win the fight between the Grizzly bear and the Polar bear. It's a point of contention. Polar bears are larger and heavier than grizzly bears, with sharper teeth and more strong paws, yet grizzly bears are more robust, have a compact bone structure, and are more aggressive than Polar bears. Polar bears are the largest bears but are not as tough as other bears. In comparison to grizzly bears, polar bears have slimmer and longer craniums. Grizzly bears have thicker, shorter, and heavier craniums and a stronger shoulder structure.

When the ice melts, polar bears are drawn to grizzly areas, where they can fight grizzly bears. In such encounters, grizzlies attack polar bears with all their strength and might, making less aggressive polar bears withdraw and retreat. In some cases, grizzlies are also known to attack and kill smaller males and female polar bears.

From all this, we can tell that the grizzly bear is the clear winner in this battle of beasts. Though situations can change the results, the polar bear may also be the winner.
