Penguin, which I recall deep-dive to remarkable depths and must 
therefore require a long period where they do not breathe. What is 
even more remarkable is their ability to feed on krill etc at these 
depths under what one would presume to be substantial oxygen-debt. As 
for the physiology, we may need to consult a bird physiologist on that 
one. Are there any other thoughts?
