So the essential difference lies in their life cycle and physical appearances.
Do amphibians breathe through lungs. When a toad is inactive the skin usually absorbs enough oxygen to meet its needs. There are some salamanders called the lungless salamanders that have no lungs and rely entirely on their skin to breathe. Frogs Can Breathe Through Their Skin.
As tadpoles metamorphose into adult frogs they begin to breathe through lungs. Most amphibians breathe through lungs and their skin. Most amphibians breathe through lungs and their skin.
Likewise how do amphibians breathe. However some salamanders remain in. Do Amphibians Breathe Through Lungs.
Amphibian skin is moistened by mucous secretions and is well supplied with blood vessels. Tadpoles and some aquatic amphibians have gills like fish that they use to breathe. Consequently do amphibians breathe air or water.
Oxygen from the air or water can pass through the moist skin of amphibians to enter the blood. To produce inspiration the floor of the mouth is depressed causing air to be drawn into the buccal cavity through the nostrils. The mechanism of lung inflation in amphibians is the buccal cavity mouth-throat pumping mechanism that also functions in air-breathing fishes.
Most amphibians breathe through lungs and their skin. When amphibians first hatch from their eggs they live in the water. With some amphibians it appears that they can breathe underwater when in fact they are holding their breath.
