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.
Although a polar bear is much better equipped, it's only 1600 lbs compared to the seal's 8,800. The bear would have to come close to attempt to kill it, and when it does the seal could just crush it.
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.
Aside from humans, lions are the only predators powerful enough to kill an elephant. The males, being 50% heavier than the females, are especially suited to the task. It typically takes seven lionesses to kill an elephant, but just two males could do the same. Even a single male can overpower a young elephant.
A grizzly bear is likely able to beat both a polar bear and a black bear in a battle for survival.
However, the polar bear would likely win the battle in a head-to-head fight featuring two fully grown males. Their larger mass, stronger bite force, and greater stamina would allow them to outlast the smaller, weaker tiger.
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.
Carnivores (meat eaters) such as lions, hyenas, and crocodiles may prey upon young, sick, orphaned, or injured elephants. Humans are the greatest threat to all elephant populations.
In an elephant vs hippo fight, the elephant is going to win. Assuming both creatures are fully grown adults, the elephant is just too big for the hippo to handle.
An elephant would beat a bear in a fight. Even though we have granted this hypothetical bear the best features of all the various species, the fact remains that they cannot do enough damage to kill an adult elephant. A fully grown bull elephant would most likely smell or hear a bear coming long before it showed up.
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.
With that said, the polar bear has the advantage of speed, strength, and endurance. Its large size and powerful jaws give it the upper hand, while the silverback gorilla's smaller stature means it would have a hard time competing against the bear's strength and agility.
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.
An elephant would win in a fight against a gorilla. Gorillas are certainly powerful and smart animals, but they lack any definitive means of killing an elephant. Unless they happened upon an elephant lying down and managed to inflict severe bites to them, a gorilla simply would not stand a chance.
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.
Exerts Most Absolute Force: Whales
A blue whale can generate a maximum force of approximately 60 kilonewtons. Whales can claim the title of the strongest creature on the planet simply due to their enormous size.
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.
A lion is large, but it can't deal with 20 times its own weigh being pushed into its body by a rampaging beast. Multiple lions can kill an elephant, or a large lion can kill a young elephant. However, there is no competition between an elephant and a lion in a one-on-one setting.
“We noticed that the elephants were more scared of tigers than of leopards,” says Vivek Thuppil, who carried out the work with Richard Coss, professor of psychology at the University of California, Davis, as part of his PhD in animal behavior.
Animals with no natural predators are called apex predators, because they sit at the top (or apex) of the food chain. The list is indefinite, but it includes lions, grizzly bears, crocodiles, giant constrictor snakes, wolves, sharks, electric eels, giant jellyfish, killer whales, polar bears, and arguably, humans.
The ultimate charismatic megafauna, the largest of all land mammals, the megaherbivores that can radically change their environments. But these goliaths are afraid of tiny insects – bees. And where they are in danger from humans, this fear is being used to save their lives.
Polar bears have a powerful bite force of 1200 psi, the strongest amongst all bear species. Their large size contributes to how strong they can bite and what makes them the most deadly bear in the world. The largest polar bear ever recorded weighed more than 2,000 pounds and had a height of around 11 feet.
Polar bears are generally more aggressive than grizzly bears. Example: in the northerly Norwegian islands of Svalbard, there is a significant polar bear population. They're aggressive enough that when outside settlements it's mandatory to carry firearms to scare off polar bears.
Would it surprise you to know that an adult bear has almost no predators? Bears are large and can be quite intimidating so they don't have many enemies. Their biggest enemies are humans and each other. It's the cubs and the smaller females that have to watch out.
