Skin Amphibian, 400X c.s.
Young amphibians generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrialsalamanders and frogs lack lungs and rely entirely on their skin. To compensate for their thin and delicate skin, amphibians have evolved mucous glands, principally on their heads, backs and tails. The secretions produced by these help keep the skin moist.
