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.
Another example of my definition of limb robusticity:
A 500-pound polar bear has a slightly longer humerus, radius, and ulna than a 400-pound tiger.
However, the polar bear's humerus takes about 56-58% of the total arm length; the tiger is 54% of the total arm length.
Even though polar bears have a greater arm span than tigers, the upper arm of the polar bear still is responsible for more of the total arm span than that of the tiger's, thus greater limb robusticity= ratio of upper arm length/lower arm length.
