Amphibians Breathe Through Skin

Specific species, such as the lungless salamanders, lack the primitive lungs that other amphibians have and breathe exclusively through their skin. They supplement this with gas exchange through the skin. 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.

They live underwater and breathe through gills at one stage of their life, and live on land breathing through lungs at another stage.

Amphibians breathe through skin. However, some adult amphibians breathe only through their skin and are lungless. To breathe through their skin, the skin must stay moist/wet. Some crocodiles swallow stones and rocks so that they can dive deeper underwater with more ease.

When their skin is moist, and particularly when they are in water where it is their only form of gas exchange, they breathe through their skin. The moist skin allows the oxygen to diffuse at a sufficiently high rate. Contrary to popular belief, most reptiles are not actually slimy.

So there are many amphibians adapted to spending a bit or a lot of time underwater. They breathe through gills while they are tadpoles. All adults are carnivorous but larvae are frequently herbivorous.

Most amphibians have thin skin that is very permeable (allowing liquids and gases to pass through it easily). As we’ve already learned, amphibians are very different to reptiles. They are vertebrates and cold blooded like amphibians.

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. Amphibians breathe by means of a pump action in which air is first drawn into the buccopharyngeal region through the nostrils. The skin of amphibians is a major site of respiration in all species for which measurements are available.

The skin breathing or breathing through the skin occurs in animals found in quite humid and even aquatic environments, this despite some count on lungs. In areas where water is scarce, amphibians are able to simply absorb any moisture within the soil. Adult amphibians either have lungs or continue to breathe through their skin.amphibians have three ways of breathing.
