“Both walruses and polar bears are powerful in the water. Both could handle most potential predators, but not killer whales,” Kovacs said.
Do orcas have predators? Orcas are apex predators, which means they're at the very top of the food chain and they have no predators. Killer whales are some of the largest and most powerful animals in the ocean, and no other predator is able to challenge them.
Adult polar bears have no natural predators, though walruses and wolves can kill them.
Whale against Shark Who would win in a fight to the death? Although the great white shark has a fearsome reputation, in a straight fight it is outclassed by the orca. Not only are orcas much bigger, they are also smarter.
In the battle between a megalodon and an orca pod, the orcas would have the advantage.
But do sharks have a boogeyman they are afraid of? Well, it turns out they do. And they fear this black-and-white terror so much it's driving them away from what used to be some of their favorite spots. Great white sharks (Carcharodon carcharias) were once an icon off South African waters, giving it ...
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.
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.
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.
Absolutely. Killer whales have speed and size on their side. Even though saltwater crocodiles are large and armored, they're not strong enough to fight off a killer whale. If orcas can kill great white sharks, they can kill saltwater crocodiles.
#1. Wolf. The wolf is the top apex predator in the world.
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.
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 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.
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.
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
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.
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.
Polar bears can kill walruses on land, but they would probably lose the fight in the water. A polar bear would win a fight against a walrus on land, but a walrus would kill the polar bear in the water. Polar bears are highly aggressive, powerful, and smart.
With a stomach volume of almost 10,000 litres, the results suggest that the megalodon was capable of eating prey up to 8 meters long – whole! This means that today's top ocean predator, the killer whale, could have been eaten whole by this ancient sea monster.
Killer Whales
When you think of top ocean predators, you probably think of sharks. Great white sharks, to be exact. But the true ruler of the sea is the killer whale. Killer whales are apex predators, which means they have no natural predators.
"This kind of association between one species and its apparent predator is unusual." It turns out the dolphins have nothing to fear from these particular killer whales, also known as orcas.
