The reason I brought up this topic is because there are some whom think polar bears only specialize in animals like seals.
They do not have that much experience in hunting ungulates as much as grizzlies and while they have lower acceleration spped compared to grizzlies, they can run longer strides since there are accounts (though brief) saying they can outrun a reeindeer over a short distance.
They are acctually more agile than they look and I do believe a large polar bear does have the weaponary to kill large bovids (e.g. gaur and cape buffalo) even though it might be a dangerouse task, it is going to be easier to take them out once the polar bear has got its hold on the necks of the gaur or cape buffalo compared to taking out walruses which have a neck almost as thick as its body coupled with blubber and four inch thick skin.

I believe that although the grizzly bear has higher acceleration in speed compared to the polar bear, the polar bear can run longer strides thus making it able to outrun reeindeer over a short distance. Can anyone clarify that? I could not combine the two threads so I had to combine them as separate posts. IMO, these questions overlap. The reason I brought up this topic is because there are some whom think polar bears only specialize in animals like seals.They do. The vast majority of a polar bear's diet is seal. It is true that polar bears are able to prey on other mammals & even fish on very rare occasions but basically it's either seal or nothing. How agile is a polar bear or how formidable their weaponry is or how fast they can run as it relates to hunting ungulates/bovids is secondary because the bigger problem a polar bear faces in this scenario is overheating which can occur even in cold/icy Arctic conditions to say the least about warmer terrestrial land. |

[ The reason I brought up this topic is because there are some whom think polar bears only specialize in animals like seals.They do. The vast majority of a polar bear's diet is seal. It is true that polar bears are able to prey on other mammals & even fish on very rare occasions but basically it's either seal or nothing. True. Yet they are accounts of them killing musk oxens though those usually consist of old bulls which have been seperated from the herd and they do occassionally kill belugas, narwhales, and walruses. And some downplay the bears strength because it feeds mainly on seals which I highly disagree with considering other animals that eat only plants or insects and still can be deadly. Brown bars prey mainly on fish and berries though some prey on ungulates more yet they would be stronger than smaller predators which hunt larger prey more often. [How agile is a polar bear or how formidable their weaponry is or how fast they can run as it relates to hunting ungulates/bovids is secondary because the bigger problem a polar bear faces in this scenario is overheating which can occur even in cold/icy Arctic conditions to say the least about warmer terrestrial land. At least the polar bear is still more agile than the ungulates (e.g. gaur, cape buffalo, and bison) and while they do overheat, they acctually do fight till death during mating season. Other animals like siberian tigers are said to overheat as well (there was an account that say brown bears overheat during winter because of the fat stored up - I am not downplaying brown bear in any way). Furthermore just because an animal like a crocordile has low stamina, its jaws are still able to kill larger prey if its large enough. This being said, I believe that once or if a large polar bear catches a gaur/bison/ or musk oxen (which are acctually easier to kill than walruses) in the flank or neck, overheating won't count much  . Sadly overheating occurs more frequently given global warming  . |

Anyone trying to minimize either the brown or polar bear as you describe it is clueless & IMHO such communications are not worth the effort. In their respective environments both sit a top of the food pyramid & both have enjoyed impressive feats of predation.
