There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.
That is why I believe the kodiak bear is stronger pound to pound although I agree with you a polar bear with a decent weight advantage will be stronger. Feel free to disagree.
Interesting information and I appreciate it, however at least one bear expert will disagree in the last point (the hump), check what Dr Andrew Derocher (2012) says about it:

He says that grizzly bears hump is just more exacerbated because of the skin, not because is bigger itself.
It make sense, as polar bears are active hunters and, in theory, they should be stronger to kill its prey, which like you showed, it could be even belugas and walruses of large size.
I don't know what you think? After all, my data on bears is not as large as in felids.
