Well, according to LiveScience, researchers discovered that moles have adapted an advanced way of removing toxic carbon dioxide from their blood in order to survive in subterranean environments. Animals living in places with low oxygen levels have an enhanced ability to bind oxygen to its transporter molecule, hemoglobin. So the mole’s ability to bind oxygen is not extraordinary, but it can also store deadly carbon dioxide in hemoglobin without having to release it into the air. This gives the mole the ability to re-breathe its own exhaled air, suggesting a possible future treatment for lung disease patients.
