Perfect example is how the OP say goes so far to say bat lungs are better (because they are more efficient as they have more surface area per volume) but they also are seemingly more fragile: suffering barotrauma from extreme changes in pressure: https://www.newscientist.com/article/dn14593-wind-turbines-make-bat-lungs-explode/ https://www.newscientist.com/article/dn14593-wind-turbines-m.... > Baerwald and her colleagues believe that birds do not suffer the same fate as bats – the majority of birds are killed by direct contact with the blades – because their lungs are more rigid than those of bats and therefore more resistant to sudden changes in pressure.
