Excerpts from the journal of Paul Ponganis who has studied emperor penguins in the field for more than 20 years. He is both a medical doctor (anesthesiologist) and marine biologist and has combined these fields to pursue a lifelong fascination: oxygen regulation in mammals and birds.
Ponganis believes that by studying emperor penguin physiology, he can help doctors better understand hypoxia in human patients.
