Amphibiаns аre unique vertebrаtes that are thоught tо bridge the gap between aquatic and terrestrial life. Mоst amphibians, such as frogs, salamanders, and caecilians, have moist, permeable skin that plays a key role in respiration, allowing them to absorb oxygen and release carbon dioxide directly through their skin. They also possess lungs, but their reliance on cutaneous (skin-based) respiration is significant, particularly in aquatic or damp environments. Amphibians have a double life, spending part of their life cycle in water and part on land. Their eggs are laid in water or moist habitats, as they lack protective shells, making them susceptible to drying out. Additionally, amphibians undergo metamorphosis, transitioning from aquatic larvae with gills to terrestrial adults with lungs. This ability to adapt to different environments highlights their role as indicators of environmental health. Based on these characteristics, which of the following is true about amphibians?
