Amphibians transport oxygen across the skin.
<h3>Amphibians </h3>
Tetrapod animals belonging to the class Amphibia, amphibians are ectothermic. The class Lissamphibia comprises all currently existing amphibians. They live in many different environments, the majority of which are terrestrial, fossorial, arboreal, or freshwater aquatic settings. As a result, most species of amphibians begin life as larvae that live in water, but others have evolved behavioral adaptations to get around this.
Typically, the young change from a larvae form with gills to an adult form with lungs. Amphibians use their skin as a supplementary respiratory surface, and some small terrestrial salamanders and frogs don't have lungs and only use their skin for breathing. They resemble reptiles like lizards on the surface, but reptiles are amniotes, like mammals and birds, and do not need bodies of water to procreate.
