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.

It seems that the brown bears skull grow taller while the Polar bears skull grew wider.
At least based off these two scans. But its hardly enough for a rule, which I get.
