Bear Strength

[Pckts]

Wouldn't the shoulder impede the polar bears main purpose?
The reason they have a thinner skull and neck is so they can penetrate seal pup burrows under the snow correct?
The reason they would have more massive limbs and hindquarters would be for dragging prey such as walrus and beluga out of the water I would think.
I also assume that the need for blubber out weighs the need for excess muscle in an are where they don't require it.... In the shoulders. Polar bears aren't diggers while brown bears are which I assume is why they have the embellished shoulder hump. 
That's just my theory on it, nothing more. Reply
