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.
And regardless of them being smaller subspecies of females used we need to understand the benefits of a smaller clavicle. The smaller clavicle allows for more mobility without compensating the Tigers muscle mass in it's forequarters. Being an ambush hunter the Tiger needs to be strong and agile as well as carrying it's head low compared to a Lion which holds it's head high and generally goes on a longer, more sustained hunts.
Obviously the clavicle isn't going to impact muscle mass in the forequarters since Tigers have chest girths equal or greater than any lion which is the same in their forelimbs.
