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.
The above shows the relative nasal aperture area to body mass ratio of a lot of cat species. Those who fall above the lions have more nasal aperture area relatively and vice versa for those below. A proportiontaly larger nasal aperture area would be indicative of higher air intake per mass, and in a sense more efficient breathing. Lions and cheetahs, from the big cats, are the more efficient breathers. That makes sense considering the more cursorial lifestyle. The jaguar, on the other hand, was below average. Such is perhaps explained by it being a stocky, short burst predator generally easily and quickly overpowering its usual prey.
