A hippo would win a fight against a polar bear. The hippo is larger, stronger, has better offensive powers and a defense that would allow it to last longer in a battle than a polar bear.
Adult polar bears have no natural predators, though walruses and wolves can kill them.
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.
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.
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.
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.
If the grizzly were fighting a wildebeest or moose, it'd only need to land one big bite. But this is a grizzly bear vs. hippo battle, and hippos have thick hides. The grizzly bear must go all out with multiple bites and claw slashes to overpower the thick-skinned hippo.
It is unlikely a gorilla would be able to match the strength of a hippo, or get close enough to do damage without getting severely injured. The tough skin on a hippo will likely keep them safe from any attack a gorilla throws at them.
Hippopotamus should wreck a gorilla on land with little to no effort and in the water with no effort. A hippo can get up to 16.5 feet long, 5 feet high (from hooves to shoulder) and weigh up to 9,000 lbs [1]vs a gorilla which can top out at about 6 feet tall and 500 pounds [2].
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.
Gorillas are strong and powerful animals. They are known to be able to fight off lions and other large predators.
A human cannot outrun a bear if being chased. All bear species could easily chase down the average human. The only scenario where a human might out-sprint a bear is if a polar bear was chasing Usain Bolt. A human can, however, outrun a bear in terms of distance.
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.
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.
Even if a swimming tiger catches up with a hippo, it'll have a tough time winning the fight. Hippos have thick, strong skin that protects them from predators. Plus, their massive body makes them almost impossible to take down. Hippos have the most powerful jaws in the animal kingdom with a bite force of 1,800 psi.
Predators. Leopards and crocodiles are large carnivores which may prey upon gorillas. Humans are the greatest threat to all gorilla populations.
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.
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. Hippos are too smart to pick a fight with an elephant, so they have no idea what it takes to bring one down.
Two ton hippos are quite capable of killing a lion. He drives the predator away from his old enemy.
A hippo would win a fight against a polar bear.
Sure, the polar bear could use its claws to cut the hippo to ribbons, but it would take some time and power to cut through all that flesh and fat.
A grizzly bear would win a fight against a lion, probably with a grizzly bear breaking the lion's back or biting through its skull. The lion indeed has an advantage in terms of their skill in hunting, especially if they are attacking in a pack.
They conclude that while one on one, a tiger would certainly best a lion, in the wild the lion pride could hold their own against the solitary tiger.
Lion vs Wolf: Physical Defenses
Although they can each use their size to scare off prey, only the lion can use its immense size to demoralize enemies in such a way that a pack of hyenas has trouble finishing a single lion. Lions get the advantage in terms of their physical defenses.
