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.
It may be difficult for old or big one hippos. But as for child hippo may be easy. Nile crocodiles, lions and spotted hyenas are known to prey on young hippos. What would win a fight between an elephant and a hippopotamus?
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 biggest determining factor in a fight between a rhino and hippo would be whether the fight was in the water or on land. A fight on the land could end with a rhino charging at 30mph with its horn and strong neck muscles thrusting into the side of hippo, knocking him over, and using his horn to finish the hippo off.
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 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.
A hippo would win a fight against a solo lion, and it would even fight several lions to a draw. The hippo's sheer power and ability to hide in a place lions must visit, the water, would give them an advantage in a fight.
A hippo would win a fight against a crocodile. Although crocodiles are large, powerful creatures, they cannot kill a fully grown hippo. Hippos are large, roundish animals that are much taller than crocodiles. The only place they would be vulnerable to attack is their legs.
A lion would almost certainly win in a fight against a gorilla. The reasoning should not be all that surprising. A lion will stalk and ambush a gorilla in the dense vegetation of their natural habitat by waiting until it's dark to have the edge. They have a good chance at ending the fight in seconds.
Hippos are among the most dangerous African animals because they are very aggressive, have little fear of humans, they can outrun a man, and are unpredictable. Hippopotamus is also a valued food source for many Africans.
“Both walruses and polar bears are powerful in the water. Both could handle most potential predators, but not killer whales,” Kovacs said.
The two species most often reported to prey upon rhinos – usually young ones – are lions in Africa and tigers in Asia. However, leopards, hyenas, wild dogs and Nile crocodiles are also known to kill African rhino calves on occasion. By far, though, people are rhinos' #1 enemy.
The strongest land animal in the world is the elephant. The typical Asian elephant has 100,000 muscles and tendons arranged along the length of the trunk, enabling it to lift almost 800 pounds.
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].
No predators hunt lions to eat them; however, they do have a few natural enemies, such as hyenas and cheetahs. Hyenas compete with lions for food and often try to steal their kills.
Mountain lions are top predators. They may be preyed on by other mountain lions, wolves, or bear when they are young or ill.
At the top of the food chain, orcas are commonly spotted in the seas of Western Australia between January to April each year. Five hours south-east of Perth, The Bremer Bay Canyon is a hive of killer whale activity, and orca-watching tours headed for 70 kilometres off the coast offer a 90% sighting rate.
A bear would win a fight against a lion. Bears have the advantage in just about every aspect, from size to offensive capabilities. The only time that a lion would win is if it managed to sneak up and ambush a bear, leaping onto it and biting into its head with such power that it shattered the skill.
But despite their size and strength, there are animals that do prey on them. Man appears to be their biggest predator. Big cats like leopards and panthers sometimes kill and eat these big reptiles. Large snakes can also do a lot of damage to alligators and crocodiles.
This confirms the general agreement in the literature that snakes and spiders are the most intensively feared animals in humans with the highest prevalence in the general population.”
