Breathing is very common in the Wild, as you might imagine. Happily, a Reader* has written in to YIR, asking about it.
Rhinos are not only accomplished at Breathing, but We need lots of Air, due to perpetual Ruminations and Scentographic Analysis. Our systems need ventilation. Air is good for that.
Rhinos don’t take Air for granted, that’s for sure. Very useful, Air. Calming, actually.
