Do Amphibians Breathe With Lungs. Thus, they breathe into their lungs opposite to how mammals do, using positive pressure to inhale and negative pressure to exhale. There are aquatic amphibians too that have gills (fish) to breathe.
How do terrestrial reptiles breathe? When they are tadpoles they breathe through gills. The reptiles’ lung has a much greater surface area for the exchange of gases than the lungs of amphibians.
There is another wonderful feature of the amphibian’s organism.
Yes amphibians breathe through their lungs and skin. Clearly, how amphibians look varies depending on the stage of their life. They don’t have gills, and instead of gills, they do have papillae that do the same function as gills when they are inside water for a long time. Their skin has to stay wet in order for them to absorb oxygen so they secrete mucous to keep their skin moist (if they get too dry, they cannot breathe and will die).
