It's a POLAR BEAR, the largest bear (alongside the omnivorous Alaskan brown bear the 'Kodiak bear'') and the largest land predator on earth. It can weight up to 1500 pounds, it has a bone crushing bite force (42 teeth closing down with a force over 440 psi), and takes down walruses. It's thick blubber(4 inches of it) would protect it from most major damage, and the fact that it's paws are gigantic (can rip off a head of an adult human with a single blow), means it could destroy the tiger within minutes maybe. Yes, some Siberian tigers have been known to kill grizzly bears, but a polar bear is just colossal (stands fully at upright an adult males can stands 10 feet in their hinder legs). They live in the Arctic, another factor that gives the bear the advantage - the Arctics a snowy wasteland.
POLAR BEAR!
(But I do still love tigers - they're awesome)
I totally agree, the polar bear is the biggest land carnivore growing to a length of around 2.5 metres which is basically just under 2 metres, so yes the polar bear would win.
Possibly, possibly not. Polar bears are quite a bit larger than Siberian tigers are, so there could be an advantage there. However, polar bears and Siberian tigers rarely, if ever, meet, so any fight between these two animals is nigh to impossible.
A polar bear could kill any tiger with ease, but these two animals would not really meet in the wild.
The black bear would win because it is heavier and can stand up.
Here's how it would work: Tiger or bear eats bat. Tiger or bear eats monkey. This leaves the bear and tiger to duke it out. So, what happens here really depends on the species of the tiger and the bear. Siberian versus black bear, chances are the Siberian will win. Bengal versus black bear, could be a draw or the black bear wins because tigers don't like going after animals that can fight back. Bengal versus grizzly or brown bear, high chance that grizzly or brown bear wins. Siberian versus grizzly or brown bear though, could be a draw, could end up that Siberian wins because brown bears actually make up 6% of the Siberian's diet.
The Siberian tiger is stronger and longer than the black bear and also can eat them, but against brown bears, it would have a little trouble.Answer 2It depends on who is bigger and the place these two animals are fighting. Black bears can kill siberian tigers if they attacked from the back.
The tiger would, Brown bears make up 1-1.5 % of there diet. Bears may be heavier but the tiger is faster and better fighter then a bear. Tigers are also very muscular compared to a bear that's more fat then muscle. The Siberian tiger could tale down any bear you wish; Koala, black , teddy, polar, panda, Kodiak, Grizzly
Depends on the age and sex of either animal. The answer would be no if you're comparing a male Siberian tiger with a male brown bear.
Most likely not. Since Russian Brown bears (which are close kin to the American Grizzly bear) have been known to be killed by Siberian tigers--1.5% of a Siberian's diet is made up of bear--it is highly likely that a grizzly bear would not be able to kill a Siberian tiger.
Since siberian tigers are faster and better hunters with good weight and length, the siberian tiger would have a chance to fight the grizzly bear off. In most situations, grizzly bears have been known to kill siberian tigers and siberian tigers have been known to kill grizzly bears. The grizzly bear will do anything to fight down the siberian tiger by using its claws, muscles, and teeth. Since a siberian tiger is good enough when its got its good body weight, then it could definitely win such a fight.
Bear would win
That all depends on the species and sex of either species. For instance, a Siberian tiger may weigh a bit more than an American black bear and an Asian black bear, but a Sumatran and Bengal tiger may weigh about the same or equal to a male American black bear.
Enemies of the grizzly bear are primarily other grizzly bears, wolverines and human hunters and poachers.
Depends on the experiences and age of each animal. A bengal tiger would usually beat an asiatic black bear in a combat, but an american black bear would stand more of a chance. American black bears are bigger in size compared with asiatic black bears, and a very big male can come across a small female brown bear, in which siberian tigers prey on. Asiatic black bears can weigh in size from 150 pounds to 440 pounds. American black bears are 200 pounds to 650 pounds. Bengal tigers weigh 450 pounds to 620 pounds. Even though the american black bear and the bengal tiger lives in different continents, the weight and size of the american black bear over a bengal tiger would make the american black bear dominate over the bengal tiger.
It really depends. A Siberian tiger is quite a bit larger than a black bear, and just as an adept hunter (probably better) as a black bear. Black bears are quite aggressive themselves, with the fact that they have to defend territories (males) or cubs (females) against other predators like other black bears, grizzlies, cougars, wolves and coyotes. And even humans. However, such a fight can only be imagined because in reality, black bears and Siberian tigers never have nor will meet in the wild. So, in letting my imagination run wild, I would say that no, a black bear could not kill a Siberian tiger because the tiger is much larger and probably more fiercer than the bear, which gives it an added advantage in "defending" itself against such a bear.
