Adult polar bears have no natural predators, though walruses and wolves can kill them.
Hippos are more powerful than polar bears. Polar bears have sharp, curved 4-inch claws that they can use to grab their prey and hold it in place while delivering a 1,200PSI bite. That is an incredibly powerful chomp that can help them break bones and remove the flesh from other animals.
Adult polar bears have no natural predators except other polar bears. Cubs less than one year old sometimes are prey to wolves and other carnivores. Newborn cubs may be cannibalized by malnourished mothers or adult male polar bears.
Ayotte made headlines around the world in November 2013 when he rescued Montrealer Erin Greene, 32, from a polar bear attack in Churchill. Ayotte beat the bear with a shovel, which distracted it long enough for Greene to escape.
The lion is the winner of the animal battle!
Even in a one-on-one fight, the lion stands a good chance of walking away from the champion. Polar bears have great endurance in the water and can swim for miles. But on land, these large bears can get dangerously hot.
However, if it comes down to one-on-one combat, the polar bear will have a huge advantage over the gorilla. A polar bear's jaw can exert up to 1,200 pounds of pressure per square inch which is twice that of the silverback gorilla.
If a tiger could get its teeth around a bear's jugular or on its spinal cord, it could quickly make short work of a smaller polar bear. However, the polar bear would likely win the battle in a head-to-head fight featuring two fully grown males.
Crocodiles are too large and strong for bears to overcome. A fully grown saltwater crocodile would win a fight against the largest bears. Size matters in these fights and crocodiles have that advantage. Bears are undoubtedly strong, but they've never faced anything like a crocodile to know their weaknesses.
The bottom line: in a fight between a polar bear and a grizzly bear, the grizzly bear reigns supreme.
An elephant would win in a polar bear vs elephant fight. The elephant is simply too large for the bear to do anything meaningful against. The polar bear can't exactly leap onto an elephant's back, so it would only be able to attack the elephant's legs and stomach area.
A dung beetle is not only the world's strongest insect but also the strongest animal on the planet compared to body weight. They can pull 1,141 times their own body weight. This is the equivalent of an average person pulling six double-decker buses full of people.
Although a polar bear might be the best match out of any bear for a shark, it would still lose. It doesn't have the toolkit needed to slay a creature so much larger, faster, and deadlier than it. The shark would probably attack from behind or beneath the polar bear, tearing open the bear's blubbery middle.
In the battle of the grizzly bear vs tiger, a Siberian tiger would win a fight against a grizzly bear. The Siberian tiger is an ambush predator, and it's the only big cat that comes close to the grizzly bear in terms of size and power.
If the fight takes place in an open area, then the rhino would likely win due to its greater speed and agility. However, if the fight takes place in water, then the hippo would likely have the advantage due to its greater strength and jaw power.
Since adult hippos can hold their breath for 30 minutes, the brown bear won't be able to survive. Grizzly bears are capable of being fierce killing machines. But they're only the ultimate predator when they're on land.
They are both highly aggressive creatures, so a prolonged fight could be brutal. Even then, the lion would probably come out on top, making up for its relative lack of stamina with sheer power. A lion has a good chance of killing a gorilla in a one-on-one fight. The only thing is that a lion rarely fights alone.
Among all bear species, both the grizzly bear and polar bear take the crown as the strongest. Weighing more than around 800 pounds — the maximum recorded size is twice that figure — an individual male grizzly is equivalent to around five humans in strength … and even more when enraged.
Grizzly Bears have 20 claws, several inches in length, one on each toe of their four feet. Silverback Gorillas have nails on their fingers and toes like humans. The grizzly would more than likely win in a fight against a Silverback gorilla.
A tiger would kill a gorilla in a fight. If a tiger managed to ambush a gorilla, the tiger would immediately kill it. Although the gorilla is strong, the fact is that it could not stop 600 pounds of charging muscle and teeth.
Tigers have an advantage over rhinos because of their speed and agility. However, they are significantly smaller than rhinos, giving them an edge in size and strength.
A gorilla would win in a fight against an orangutan. Gorillas are far better fighters and far more capable of inflicting fatal trauma on enemies. An orangutan might escape a gorilla by climbing trees, but that is not going to defeat the gorilla.
It is a close call, but the polar bear is generally considered the largest bear species on Earth. A close second is the brown bear, specifically the Kodiak bear.
