The "King" of the bears - comparison between the Polar bear and the Brown bear

[GreenGrolar]

/\ The grizzly has a more developed hump but the polar bear seems to have more pronounced shoulder blades. It is interesting that one account does not cancel out the other. The grizzly hump does have muscle but it also has fluffier fur and fat (polar bears also have fat and thick fur to protect them from the extreme cold).

More on the shoulder hump:

Code:

In bear identification 101 the black bear’s rump is higher than front shoulders and a grizzly bear’s rump is lower than shoulder hump. On a grizzly this hump is made of fat and muscle and helps the grizzlies to dig up roots and tear apart logs to find food. The angle of this photo and the pose of the bear make the hump very obvious.

Both bears seem to have advantages that cancel out the other. Reply

The adult male grizzly bear weighed in at only 308 lbs. Another adult male grizzly bear in the documentary was estimated to weigh between 300-350 lbs. Reply
