7. Aquatic vs. Terrestrial Respiration
Amphibians showcase exceptional respiratory versatility, switching between aquatic methods like gills and cutaneous respiration, and terrestrial methods such as lung and skin breathing. This adaptability allows them to thrive in diverse habitats, though it also makes them more susceptible to environmental threats like pollution or climate change. For example, newts remain more aquatic, while toads are adapted for terrestrial life. These contrasts highlight the variety of amphibian breathing strategies shaped by evolution. Source
