The northernmost reaches of the world are home to animals that can thrive in adverse conditions. Polar bears are some of the most dangerous predators in the Arctic. They hunt seals using their intelligence, endurance, and raw power, sometimes swimming for dozens of miles to find a meal. They’re not the only deadly animals that thrive in this part of the world, though. Orcas, also called killer whales, are moving into the area as sea ice becomes scarcer. Today, we’re going to examine an orca vs polar bear fight to show you which animal would win the battle and why!

A fight between a polar bear and an orca is highly unlikely, so we’ll use the available data about these creatures to determine which one would be most likely to win a battle.

Comparing an Orca and a Polar Bear

OrcaPolar Bear
SizeWeight: 6,600 to 13,000 pounds
Length: 16 to 26 feet
Weight: 330 to 1,300 pounds
Length: 6 to 9.5 feet
Height: 3 to 5 feet tall
Speed– Up to 35 mph– 25 mph
– 6 mph when swimming
Defenses– The sheer size of this creature makes it hard to kill
– Their flesh is over 12 inches thick at some point
– The orca’s speed allows it to get away from trouble
– Orcas live in pods, providing significant protection from others
– Their fur color offers them some camouflage on ice
– Have a flesh and fat layer measuring 2 to 4 inches thick
– Large, imposing bodies make them an unlikely target for most animals
Offensive Capabilities– Orcas have an incredibly high bite force at 19,000 psi
– Their 40 to 56 teeth measure between 2 and 4 inches long
– Can use their tails to smack animals in the water
– Have a reasonably powerful bite force of 1,200 psi
–  Largest teeth measure up to 2 inches in length
– Have strong forelegs and large paws along with 4-inch-long claws that allow them to deliver a powerful bash
Predatory Behavior– Opportunistic predators that attack a variety of marine animals as they find them
– Can work with their pod to hunt animals in unique ways, such as splashing water to wash seals off ice sheets
– Ambush predators that wait above openings in ice for seals
– Also, they can act as pursuit predators – Will often scavenge any food possible

Although they’re both mammals, orcas and polar bears have many differences. For example, polar bears are terrestrial animals while orcas are marine animals. The animals’ morphologies are completely different as well.

Also, orcas are far larger than polar bears weighing up to 10 times as much as the Arctic-dwelling bears. Lastly, although orcas often live in groups, adult polar bears are usually solitary creatures except when mating or raising their young.

These are just a few of the major differences between these combatants, but we’re going to look at many others throughout this article.

Polar bears incredibly deadly hunters, and they’re easily capable of dispatching other animals in their range.


The key factors in this battle are going to be very similar to every other battle in the wild. We have to take into account defenses, offenses, predation, speed, and size. Moreover, we have to consider where this fight would sensibly occur. We’re going to examine the most important facets of this fight below and determine which animal has the edge in each facet.  

Orca vs Polar Bear: Size

The average polar bear weighs anywhere between 330 and 1,300 pounds. They grow about 6 to 9.5 feet long, and they can stand as much as 3 to 5 feet tall at the shoulder. They’re seriously large animals. The largest one ever recorded weighed 2,209 pounds!

Meanwhile, orcas weigh between 6,600 and 13,000 pounds, and they grow up to 26 feet long.

Orcas have a major size advantage.  

Orca vs Polar Bear: Speed

Polar bears are rather speedy on land. They can hit speeds of 25 mph while bounding across the Arctic. However, they can only reach speeds of about 6 mph in the water. Meanwhile, orcas have a top speed of nearly 35 mph while swimming.

Orcas have a huge speed advantage in the water where the fight will take place.

Orca vs Polar Bear: Defenses

Polar bears are solitary creatures. They’re large, powerful apex predators that do not have to fear much in their range except for humans. Their massive bodies have a thick layer of fur and flesh that can measure as much as 4 inches thick in some parts. They also have whitish-yellow fur that helps them stay hidden in their range.

Orcas are even larger than polar bears. Their vast size makes killing one of these animals very difficult. Their layers of flesh and fat can reach 12 inches thick at some points on the orca’s body. They also live in pods with several other members of their species, making them even less approachable. For this fight, though, we’re only going to consider the one-on-one battle between the two creatures.

The orca has an advantage in terms of defense.

Orca vs Polar Bear: Offensive Capabilities

Polar bears are large, powerful animals that rely on their strong bites to kill their prey. These bears will often bite their prey’s necks, delivering a vicious bite with a 1,200 psi power behind it. They can also beat their prey around with their powerful forelegs and gigantic paws. These bears use overwhelming power to attack their prey.

Orcas are also very powerful. They can smash prey with their tails and use them to wash seals off of ice sheets, but they’re more likely to use their bite to kill prey. Orcas have a bite power of 19,000 psi, more powerful than any terrestrial animal. Killer whales have between 40 and 56 teeth measuring from 2 to 4 inches long.

Orcas have the offensive advantage in this fight.  

Orca vs Polar Bear: Predatory Behavior

Polar bears take prey and scavenge food as often as they can. They can ambush seals that come up through the ice, scavenge food and carrion, or they can pursue prey as they see it. Meanwhile, orcas are opportunists that attack many kinds of marine prey. They can hunt alone or work with their pod to coordinate and kill prey.

Neither animal has a predatory advantage that would impact this bout.

An orca would win a fight against a polar bear. Since this fight would occur in the water, the bear would be at a massive disadvantage. The orca is stronger, faster, and more capable in the water. The orca could simply attack and overwhelm the polar bear, first using its tail smash to disorient the polar bear and then finishing the job with a powerful chomp. There are not many paths to victory for the polar bear in this fight.
