Jaguar average data may be right based on weights of numerous jaguar sub-populations.

Bears are cute but they are  ......  leave it.Don't want to prolong this discussion  Joking

Actually wolf 48,Jaguar 104 and Cougars 71 kg  average look fake for any sub-population. Hope new data/table will be available soon.

They sometimes exceed 250 centimeters (10 feet) in length, measured in a straight line from the tip of the nose to the tip of the tail, although most male polar bears are a bit shorter. They are roughly twice the size and weight of adult females, which weigh 200 to 350 kilograms (440-750 lb) and achieve an adult body length of about 190-220 centimeters (up to about 7 ft). Females first breed at four to six years of age and most often give birth to two cubs in snow dens on land (some cubs are born in dens on the sea ice). Cubs stay with their mothers for two and a half years before weaning which means that unless cubs die prematurely, females do not breed more frequently than every three years. Both sexes live twenty to twenty-five years and sometimes to over 30 years. Their primary prey is ringed seals and, to a lesser degree, bearded seals.

Edit and add: You are posting on the 'Premier League' with such nonsense as - I cant imagine any bear above 500 kg because bears are timid and fatty.(except during hibernation).
Very juvenile and doesn't even make sense. 

Generally i don't trust data of Game reserves (dependent on tourism) and Hunters but we can blindly believe government data(98%).Because govt officials data may have few errors but they don't cheat and mislead public intentionally.

So,Adult male Polar bear avg 329 Kg is confirm.

THE NUMBER OF POLAR BEARS IN THE RUSSIAN FEDERATION

According to expert estimates, in the early 1990s the size of the polarbear populations inhabiting the Russian Arctic and the adjacent areas amounted to: the Kara-Barents population – 2500-5000 animals, the Laptev population – 800-1200 animals, the Chukotka-Alaska population – 2000-5000 animals. For the latter population, the estimate recommended by the Polar Bear Specialist Group of the IUCN Species Survival Commission is 2000 animals. 

Based on the results of the polar bear census conducted in 2004 in the northern part of the Barents Sea, including the area of Svalbard and Franz Josef Land archipelagos, the size of the Barents Sea part of the Kara-Barents population was estimated at approximately 2650 animals. 


Appearance & Weight. Sizes are very large. Average body length of males 2 m, occasionally to 3 m, females - 1,85 m, weight - 700 kg, but usually less. The body, neck and head much elongated, in contrast to the brown bear. Ears are short, rounded, slightly prominent fur. Limbs long, the soles are covered with dense hair. Claws large, slightly curved, dark-brown color. The tail is noticeably longer than the brown bear. The coat is very thick and dense, but short. Ear hair is shiny, almost white, usually with yellow tops. Underfur pure white. When moving overland fur bears become a dirty gray. 

The polar bear is the largest land carnivore with adult males measuring up to 280 cm in length, and up to 160 cm in height at its shoulders. Males typically weigh 400-600 kg, although the weight of an adult male has reached 800 kg in some reported cases. Females are smaller and lighter (130-300 kg), however, the weight of a pregnant female going into a den may reach 500 kg.

"When fully grown, adult male polar bears in Canada range in weight from 450-550 kg and most adult females weigh between 160-270 kg."

So,Some Russian scientists claim 400-600 kg average and Americans research says 329 kg for Polar bears.

2.Who take those 'guess' weights based on Immobilon Etorphine dosage seriously?? 

Anyway, Polar is 329 kg and grizzly 193 kg as per reputed studies..There is nothing wrong it....  just take it easy... actually i thought they are 260kg and 180kg respectively based on their images even though some fanboys claim they are above ton Ha Ha

These are all reputable studies Vinay; different locations. 329 kg ( 725 pounds ) is less than the weight of the average mature male coastal brownie. As for grizzly, this also depends on location. Yellowstone - about 490 pounds. Inland Alaska ( south of the tundra ) - about 550 pounds. You are obviously cherry-picking your data to fit your agenda. We understand that your favorites are the big cats. If you really believe in them, then you should willing to provide accurate data.

Truth is Vinay; 2,000+ pound polar bears have been weighed although certainly not an average.

 Re-posting for you............. 83 adult male Polar bears and 65 Grizzly bears measurement is cherry picking and propaganda data for you!!  Funny (Gave pdf links too.. Still...) 

Measuring 83 and 65 adult bears for more than a decade is not a JOKE and it is not possible for an ordinary persons except huge funding and support from Government (or very reputed org).

Anyway,you don't accept the research findings!! ...Good....Please don't no-body forced you to accept this.

Vinay, I'm not saying that the studies you posted are inaccurate; I'm saying that you cannot state these measurements as averages for either the grizzly or the polar bear except within  those particular locations. Overall, the average polar bear ( mature male ) would likely weigh somewhere  between 950 and 1100 pounds. There is simply no such animal as an average grizzly - so many populations scattered across Europe, Asia, and North America and each population different. Perhaps Peter, Guate, or perhaps GrizzlyClaws can; I cannot.

Average is not said like this: 'somewhere between 950 and 1100 pounds'. 

Average is total weights/number of Animals........... so, it is a NUMBER not a RANGE.If you are confident say their average is 950 or 1000 or 1100 pounds from 1 or 2 or 10 reserves.

BTW Not only Polar, Brown bears but also all mega fauna are scattered and there is no such animal as as average Wild Boar,Tiger,Elephant and so on still we calculate the average based on that particular zone and later add all zones to find nearly accurate average.

Average 329 and 193 kg is not a small number for a bear family!! Anyway, discussion ends here ...... you can assume what ever average for your bears.

Vinay, posting a specific number does not make it a fact. Consider this hypothetical example; let's say that in 1995, every mature male lion on earth is captured and weighed. We add up the number of those weights then we divide by the number of lions. In this way we get the exact average for the mature male lion. Then again, in 2015 we repeat this process. After 20 years, the average will not likely be the same number. 
This is the only way in which we could get the exact average weight of any animal and, of course, this would be absolutely impossible. There are few animals on earth with such a wide variation of weights as a grizzly. Depending on where he lives, a mature male can weigh below 300 pounds or as much as 1500 pounds. The weight range I gave you for the polar bear shows you just how far off the mark your number is. As for a specific number for the average weight of either the polar bear or the grizzly, that would include coming up with the average weight of each population of bears and the number of bears within each given population. Even then, within each population, not every bear is weighed; just a few samples. 
Bottom line; no number can be carved in stone as the absolute average weight of any given animal.

This is your claim : Amurs have gotten over the 240kg mark, it's the modern stp report that hasn't seen a tiger reach that size.

I asked you source then you simply gave Gaute diagram .... Even in that table biggest Amur was only 212 kg. 
(Don't know where he got that weight as far as i know it is only 204 / 6 kg refer #1)

2.So,the entire Propaganda was started from here by these persons

320 Kg NORMAL ... Funny

Sorry to say i read  fairly 'NORMAL' 1 ton Polar and Grizzly too ... You can see their scientific results above.

Attached to the tables are the sources as well as the google link to them.
You also left out the most important word in the sentence..

Fairly normal "Maximum"
Not fairly normal like you presented.



Here they are in a "table form"

This slaght et al 2005 data (your so called 249.5 kg tiger) was from Goodwin 1933 research not his own.

Didn't get it!! Why are you stopped at 240 kg ?? By your source it is clearly visible normal MAXIMUM weights are 400 kg,389 kg,384 kg and so on in a SINGLE PARA.  Funny


'SLAGHT ET AL 2005' is a strange guy.......  every tiger he measured was over 200kg but NO identification number,head body length,Total body length,Height nothing only WEIGHTS. Of-course i 100% believes him and other historic 400 kg Normal maximum weights of Amur.
