Amphibians Breathe Through Skin
The skin of amphibians is a major site of respiration in all species for which measurements are available.
Amphibians breathe through skin. Earthworms do not have lungs and breathe only through their skin. Some axolotl salamanders keep their gills throughout life. When the frog is out of the water, mucus glands in the skin keep the frog moist, which helps absorb dissolved oxygen from the air.
As compared to reptiles, amphibians have smooth skin. Yes, all amphibians breathe through their skin as adults. Their skin has to stay wet in order for them to absorb oxygen so they secrete mucous to keep their skin moist (if they get too dry, they cannot breathe and will die).
First, it means that their skin helps them breathe, since oxygen passes easily through it. Amphibians also have a pair of simple lungs but they are not sufficient on their own for breathing. The moist skin allows the oxygen to diffuse at a sufficiently high rate.
Their lungs are not powerful enough to properly supply their bodies with the needed oxygen. Amphibians have primitive lungs compared to reptiles, birds, or mammals. All earthworms breathe through their skin throughout their lives.;
Most amphibians breathe through lungs and their skin. In areas where water is scarce, amphibians are able to simply absorb any moisture within the soil. Skin is their most important and largest organ.
Because reptiles don’t have sweat glands, their skin is usually cool and dry. Oxygen from the air or water can pass through the moist skin of amphibians to enter the blood. Look at that moist skin.
