What is the strongest species of bear?

i would say polar bear but ive heard good arguments for grizzly,brown bear,and Kodiak bear

  • In all of this, the overall build of the contenders is irrelevant and so does not factor…

    To answer this most directly and efficiently – it is decisively the polar bear. The reason for this is in the wording of what you say, ‘species’. The brown bear is excluded from contention because across the ‘species’, it is considerably the smaller bear. What would make the question more interesting and hence require a more detailed explanation is if you simply asked ‘strongest bear’. Then, the largest brown bears must come into contention given their similarity in size to the polar.

    Before moving onto that, I want to bring to your attention something you have stated incorrectly…

    “i would say polar bear but ive heard good arguments for grizzly,brown bear,and Kodiak bear”

    – the grizzly and the kodiak ARE brown bears (2 subspecies), and so how you presented that is incorrect…

    Ok, the bears in contention are the polar and 3 brown bears (that is, 3 subspecies) – in size order the kodiak, kamchatka brown and the grizzly. The reason the kodiak is joined by the other 2 is that the largest subpopulations of both the kamchatkan and the grizzly are comparable in size to kodiak with some overlap. With that addressed, these 3 candidates (provided we are specifically talking of large examples from within each) are a good match in strength for the polar. In one strength dynamic, the shoulder, it is likely that relative to size these brown bears are stronger. But that is only one aspect and it does not really translate into usable power in any meaningful way here.

    The simple answer is that the 4 are evenly matched, if the 4 individuals are the same size. What decides it, by the slimmest of margins is that they do not happen to be of equal size, particularly the kamchatkan and the grizzly – even within the specific context I described above. For this reason on a statistical basis the polar is the strongest because statistically it is the largest bear. In reality I could not call it between polars, kodiaks and the largest subpopulations of the kamchatkan and grizzly.

    Donuts – breed is a term relating to domestic animals. There is nothing unusual about the size and strength of those 2.

    darksky – the grizzly is far from a close second, when you refer to the entire subspecies as you have, the consideration is not what I have detailed. As an entire subspecies, the grizzly is considerably smaller than the others I mention.

    JoeJack – that would be ‘other subspecies’ and the grizzly would not be third.

    LesCRNI – some good, informed info there…there is no rule that correlates weight with strength in any comparison, only rules of thumb. Consider a polar at 1000 lbs and a grizzly at the same weight, but the grizzly is obese and some of its weight is comprised of fat. This clearly does not contribute to strength, meanwhile (in this example) the polar is a lean 1000 lbs (typical weight of a lean mature male). I think you get my point…

    Your third paragraph is flawed, but without getting into all that, suffice to say that adaptive traits are an irrelevance to physical strength.

    The dietary strategy does not play a part beyond my cursory mention of the shoulders of brown bears. The occasional physicality involved in dealing with whales by polars is infrequent enough to be excluded in any analysis of strength dynamics across successive generations. The same reasoning can be applied when speaking of the polar bear’s thickly muscled neck.

  • i know this comes late in the conversation but again other fact has to be entered into play, when dealing with which of anything is stronger as appose to who would win in a fight you need to look at strength per pound. Since no bear even of the same breed or sub-breed aren’t always the same height or weight yet at times the smaller looking of the two wins this is due to the ratio of muscle and fat. Also age of the two would play a factor due to the live span of the breed as a polar bear lives 15 to 18 year on average where as a Kodiak lives 25 to 30 years that would mean that with both bears being 10 years old the polar bear would be technically older and there for weaker in the bodies abilities as to the “younger” Kodiak. The other factor would be place of fight, if in the arctic the polar bear is made to fight in snow where as a Kodiak or grizzly or black bear don’t fair well in cold or on ice like the polar bear, where as in the forest of Canada (being the closes to the polar bear’s home and also if summer) the heat would fatigue the polar bear much faster as appose to the Kodiak. So when it comes to pure strength the Grizzly bear can lift over 500kg, 0.8 times its body weight making it the strongest bear per pound.

  • I would say without any doubts that the strongest bear species is the Polar Bear. The Grizzly and Kodiak Bear belong to the same species: Brown Bear. It is worth noting that the Kodiak subspecies is almost the same size as the Polar Bear, so both have a really tough competition. However by comparing their size and their behavior we can find out that the Polar Bear is the strongest bear species in the World. Not mentioning that it is also the most powerful land carnivore in the World.

    The Polar Bear is definitely larger and heavier than most Brown Bear subspecies. The Kodiak Bear has roughly the same size and weight. A Polar Bear measures on average 2.2 to 2.5 meters long, head and body, the tail may add up an additional 12 cm. A Brown Bear measures on average 1.5 to 2.5 meters, depending on the subspecies: the ones that measure from 1.5-2.0 meters are the Brown Bears from Eurasia; Grizzly bears may reach 2.3 meters; while large Kodiak Bears may reach 2.5 meters, the same as a Polar Bear. Regarding weight, the average for the Polar Bear is 410 to 720 kg; compared to about 318 kg of the Brown Bear (taken the species as a whole; Grizzly Bears may reach 450 kg, and Kodiak Bears are capable of reaching 700 kg; on the other hand, European Brown Bears rarely weight more than 200 kg). The highest weight recorded for Polar Bears are close to 1,000 kg (1 metric ton), while that for Kodiak Bears is about 850 kg. As the numbers show, the Polar Bear is definitely the heaviest of all bears, and its size is only matched by the Kodiak Bear. Given its weight and size I conclude that the Polar Bear is the strongest of all bears. Strength is very related to weight.

    But there is far more than both bears’ measurements; the conditions in which they live may give us some clues to find the answer. And the nature gives the victory to the Polar Bear. It is far more resistant than any other bear. Polar bears live on the Artic, no other land animal of that size would be able to endure temperatures below -50 degrees Celsius. It is true that Brown Bears also live in similar environments (Kodiak Bears are native to Alaska; Usury Bears live in Northern Siberia, not far from the Artic); but Brown Bears do not endure the coldest temperatures because they hibernate. Male Polar Bears do not hibernate, only the pregnant females do it. An animal must be strong in order to endure extreme conditions, such as the ones in the Polar Bear’s habitat. Thus we can assume that the Polar Bear is stronger than all the other bears.

    Finally the food they eat complements the analysis. Polar Bears are the only land animals capable of hunting small whales; “small” being only a relative term, because the beluga whales and narwhals killed by Polar Bears may reach up to 6 meters in size (twice as big as a dolphin/half the size of a bus. The largest prey of most Brown Bears are deer and moose. Kodiak Bears (despite their big size) do not hunt many large animals, they specialize in salmon and fish. The Polar Bear must be a strong animal in order to hunt a whale.

    As the evidence shows, the Polar Bear is definitely the largest, heaviest, and strongest of all bears.

  • Strongest Bear

  • Polar bear, he is only equaled by the largest of the Kodiak bears.

  • The polar bear is, followed closely by the kodiak bear, then grizzly and then the other species of brown bear.

  • Polar Bear because of their enormous size.

  • Actually you are right the polar bear.

  • I would think polar bear too, grizzly a close second. Or visa versa

  • kodiak-polar bear breed. They Grow unusually in size and strenght
