Food for thought: Average mature male Arctodus simus - 1650 pounds ( 748.43 kg ). Average mature Foxe Basin polar bear - 1300 pounds ( 589.67 kg ). Difference between the two - 350 pounds ( 158.76 kg ). True. There are actually male polar bears outside Foxe Basin which are lighter than the male kodiak bears at average weight. There is quite a bit of weight overlapping between both the polar and kodiak bear. |

Here is GuateGojira stating that polar bears can hunt prey up to 2000 kg while big cats can hunt up to 1000 kg:
GUATEGOJIRA: That conclution is correct. Big cats over 227 kg can kill prey up to 1,000 kg alone.
About the polar bear, as far I know the biggest prey that they can hunt is the walrus which may weight over 2,000 kg. On the Kodiak bears, I think that the maximum prey are deer species like the Roosevelt elk of up to 500 kg, but no animal in the region is bigger than the bears, so this is a case when the predator is bigger than its prey.

Grrraaahhh once explained ( maybe I can locate the original ) the big cats have specific killing techniques which has been perfected over the course of millions of years as ambush predators.
*Basically ( in my own words ) the big cats are using killing methods like a Ninja assassin; to kill without a fight ( is the basic idea ).
Bears are completely different animals in every sense of the word. A bear must wrestle and overpower his adversary with physical force. The bear has no highly tuned killing methods. In fact, in the end, the bear gives little though to whether his opponent is alive or dead, just so long as it is disabled and no longer a bother.

Yeah, am just surprised that Guate thinks the largest prey a lone tiger can hunt is 1000 kg gaurs. He is not naming elephants, rhinos, or any of that crap.

shaggygod.proboards.com/thread/653/brown-bear-predator Bears typically kill using brute force and do not seem to exhibit any stereotyped killing postures or behaviours as seen in canids and felids (R. Boertje, pers. comm.; J. Hechtel, pers. comm.). Polar bears and brown bears have been observed to attack their prey both with bites and crushing forepaw slaps, apparently to whatever region of the prey’s body is accessible (Murie, 1985; Boertje et al., 1988; Case & Stevenson, 1991; M. Ramsay, pers. comm; J. Hechtel, pers. comm.). Sacco, T. and Van Valkenburgh, B. (2004), Ecomorphological indicators of feeding behaviour in the bears (Carnivora: Ursidae).

A 600kg polar bear is considered heavier than average.

The 600kg+ polar bear was ~19y of age; most likely an experienced veteran entering the last years of his physical wellbeing.

King KodiakI've noticed that there are two numbers specifying the sex; 1 and 0.1. Do you know which indicates which gender?

Maybe you can ask Warsaw at Carnivora, he is the one that originally posted this 10 years ago:

Does someone know how I can get into contact with Warsaw; I am unable to send personal messages to him via Carnivora. I've heard that he is on Wildfact, is his name also "Warsaw" over there?

Some more information by "Warsaw" on "Stan", the enormous polar bear:
"Biologists, for example, rarely give names to the animals they handle, but one polar bear that Stenhouse and Nick Lunn caught on Southampton Island in 1985 was so big and burly -he weighed in at 810 kilograms (1,800 pounds) -that they nicknamed him "Stan." Stenhouse keeps a picture of "Stan" on the wall of his office in Hinton."
That would make "Stan" the largest polar bear weighed during scientific field work.

No; unless he has joined Wildfact within the last year or so, he is not a member there. Perhaps nocap, thenormalguy, or kussuts can send him a message on Carnivora. |

King KodiakYes, but the 2210lbs polar bear would count as a hunting record; "Stan" was part of scientific field work. Not that I don't believe in the 2210lbs polar bear but hunters often exaggerate the weight of their trophies and one can always raise doubts on it.

Theundertaker: it would seem that 1.0 is male, while 0.1 is female. From this snake forum, they explain these numbers although i dont know if its the same situation or not:
ball-pythons.net/forums/showthread.php?172671-What-does-1-1-0-1-1-0-mean
But its just not possible to have so many females (0.1) with 400+, 500+, and 550+ kg, that's the problem, it does not make sense unless they are all pregnant females.

 Stan, the exceptionally large male polar bear will defeat any big cat both extinct and extant. Size does matter in the wild. |

Status report on the size of polar bears by "Polar Bear International": "In Hudson Bay, the mean scale weight of 94 males >5 years of age was 489 kg. The largest bear in that group was a 13-year-old, which weighed 654 kg (Kolenosky et al. 1992). The heaviest bear we have weighed in Alaska was 610 kg, and several animals were heavy enough that we could not raise them with our helicopter or weighing tripod. Some animals too heavy to lift have been estimated to weigh 800 kg (DeMaster and Stirling 1981). Females are smaller, with peak weights usually not exceeding 400 kg. Total lengths of males in the Beaufort Sea of Alaska ranged up to 285 cm. Such an animal may reach nearly 4 m when standing on its hind legs and is 1.7 m shoulder height when standing on all four legs. Chest girth for large males is close to 200 cm. Although smaller, females in the Beaufort sea were as long as 247 cm with chest girths up to 175 cm." carnivora.net/polar-bear-v-african-cape-buffalo-t5283-s60.html#p144049Credited to Undertaker on Carnivora. Warsaw originally posted that account on the now dead shaggygod forum. P/S: My fictional male blue ice bear is exactly ten times taller than Stan on all fours and also ten times his weight  . |
