I live in Virginia and the ones in Shenandoah National Park are a bit smaller than that. Even if it's 450 pound average though, it's still nowhere near 400 kgs. I agree-400 kg is much to much. IIRC, the black bear claimed to weigh that much regularly fed on garbage and was very obese. Black bears in many other regions are far smaller. Average weight of males in Spring, Summer, and Fall of black bears from Upper Columbia and Flathead in Southeastern British Columbia between 1980 and 2010 were 93.7, 103.1, and 112.5 kg.

It looks like less than a a quarter it´s weight. Male black bears can reach 400kg and 1,8m in lenght, a large kodiak reaches 750kg and 2,5m in lenght. 400 kgs?? You mean 400 pounds? No, according to wikipedia, it can reach 400kg, some captive individuals even more. But most comaprisons that I know aren´t at average, but at maximum size. but when the kodiak bear is only around 300kg, the black bear looks far too small, like less than 100kg. What does the arctodus weigh? Are there enough specimen to give an average size? 400 pounds would be a large black bear. 400 kgs is impossible.

But the black bear in the comparison still looks far too small compared to the kodiak bear, even with the weights given. Why not make a comparison of maximum sizes, they are easier to verify.

With a 100 kgs of fat, then yes it would be possible but a healthy black bear will simply not weigh that much. You can't trust Wikipedia. I can change the text and claim that a black bear has a maximum weight of 50 kg...

Herbivore Posts: 648 Group: Members Member #13 Joined: Jan 7, 2012	Thanks for the black bear data, boldchamp. Very insightful and confirms that while they can get very big 400 kgs is probably out of range. But they can get bigger than I had thought

Omnivore Posts: 1,028 Group: Members Member #88 Joined: Jan 15, 2012	400 kg is possible, and has been recorded.....but then, humans have been recorded at 1400 lbs....but i wouldn`t use such a human for comparison, or one remotely close to that weight. Edited by boldchamp, Jun 12 2012, 02:08 AM.

I don't know if they grew up together but the Jaguar seems to not have any fear of the tiger. The jag seems a bit overweight though, which is not surprising considering it's a captive animal. That is kind of a mean thing to say. LOL
