The Science Behind Amphibians’ Underwater Breathing: A Dive into Evolutionary Adaptations

11. Carbon Dioxide Elimination

Efficient removal of carbon dioxide (CO₂) is vital for amphibian survival. These animals expel CO₂ through both their skin and lungs, using whichever pathway is most effective in their environment. During prolonged underwater activity, when lung breathing is reduced, cutaneous respiration becomes the primary method for CO₂ elimination. This dual strategy highlights their remarkable adaptability. Read more
