While a polar bear can beat a Siberian tiger in the realm of brute force, it can't match a tiger's sheer speed or agility (at least on land). At top speed, polar bears can run nearly 25 miles per hour. However, its top speed pales in comparison to the ...
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.
Adult polar bears have no natural predators, though walruses and wolves can kill them. Longevity in the wild is 25 to 30 years, but in captivity several polar bears have lived to more than 35 years old. Humans probably cause most polar bear deaths, by hunting and by destroying problem animals near settlements.
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.
There were numerous reports of tigers preying on both brown bears and Asiatic black bears, but the relationship, it seems, was not that simple; there were also reports of bears killing tigers.
So, it's best to just observe these formidable animals in their natural habitats from a safe distance. The polar bear would win a fight vs. a silverback gorilla, having a size, speed, and strength advantage.
A polar bear would devastate a gorilla, this shouldn't be a debate at all. Let us have a look at how a gorilla would likely go against a polar bear in a fight. The predators of gorillas are leopards and crocodiles.
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.
A hippo would win a fight against a polar bear.
Instead, the hippo needs one or two bites to incapacitate the polar bear. Its massive teeth would penetrate the bear's fur and skin, breaking bones and ripping into organs. In this rare case, speed on land would only matter at the beginning of the fight.
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.
Predators. 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.
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.
It could simply sit on the lion and call it a victory. Lion have more speed, but they are used to hunting in packs, not individually. So a lion would have trouble fighting a polar bear alone. But if there was a fight between a polar bear and a PACK of lions, well, then the lions would definitely win.
Polar Bears can weigh up to 1700 pounds and lions up to 600 pounds. Since the lion is so much smaller than the polar bears, the lion's attack would be ineffective against the polar bear and he would just get knocked out by a swipe of the polar bear's paw or bite from its jaws.
If the two were hitting each other with their claws, it's likely the brown bear would have the advantage as their claws are more adapted to swiping. If a battle between grizzlies and polar bears turned into a wrestling match, the advantage could swing to polar bears.
However, grizzly bears are tougher than polar bears as they possess stronger and longer claws and an elongated skull with sharp and long canines that can completely separate the flesh from bone.
Massively Strong: Bears
They are swathed in huge muscles and powerful claws that enable them to dig and hunt with incredible expertise. Among all bear species, both the grizzly bear and polar bear take the crown as the strongest.
Although a silverback gorilla is very fast, quite strong, and has a longer arm span, it is unlikely that a silverback could defeat the much larger and faster grizzly bear in a fair fight.
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.
A polar bear's strength is no match for a rhino. The most it could do would cause the rhino to bleed, but ultimately it would definitely lose in a one-on-one battle with this animal, since a rhino can weigh up to 7 times as much as an adult polar bear.
An elephant would win in a tiger vs elephant fight.
The tiger is undoubtedly a fierce beast, and it might stand the best chance out of all other land-dwelling animals of successfully hunting an adult elephant. Yet, the elephant's size and power are simply indomitable.
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.
While the tiger has bigger teeth and a stronger bite, it will also take a lot of damage from the Kodiak bear. The large ursine creature would probably rear up on its hind legs, get the tiger to come close, and then bring down all its weight and power on the tiger to maul it.
