why do amphibians breathe through their skin
Animals which Breathe through their Skin. Some animals which live on land have a skin which is so thin that gases can easily pass through it. We say that they have a permeable skin. Earthworms and amphibians have a skin which is permeable to gases. Amphibians also have a pair of simple lungs but they are not sufficient on their own for breathing. Large animals which breathe through their skin also use blood to transport oxygen to their tissues and to bring carbon dioxide to the surface of the body.
