Amphibians Breathe Through On Land

They breathe through gills while they are tadpoles. To exchange gases, terrestrial reptiles depend on their lungs. Mature frogs breathe mainly with lungs and also exchange gas with the environment through the skin.

Their makeup is so convenient, that people used it when creating flippers.

Amphibians breathe through on land. They spend their lives in water and on land. They also come under the class vertebrates (meaning they have backbone or spine). Amphibians almost always stay near water in order not to dry out.

Similarly amphibians have special structures to breathe when they are on land and also when they are in water. Amphibians breathe through their skin and live on both land and in water. Their larvae (not yet fully developed offspring) mature in water and breathe through gills, like fish, while adults breathe air through lungs and skin.

The name amphibian, derived from the greek word meaning ‘living a double life,’ reflects this dual life strategy, but some species are permanent land dwellers, and others are completely aquatic. They also have fins to help them swim, just like fish. Frogs breathe with their mouths closed and the throat sack pulls air through the nose and into their lungs.

Amphibians live partly on land and in water. Although most of the amphibians have lungs, they usually breathe through their skin and lining of their mouth, whereas most reptiles do not. The larvae mature while in the water.

Frogs go from a larval stage, to being a tadpole, and eventually grow into adult frogs. Amphibians are not fully adapted on land because adult amphibians breathe through their skin, and for oxygen to diffuse from air into the skin and into the body, the skin must be moist. Amphibians breathe through skin and they go through metamorphosis.

Later, their bodies change, growing legs and lungs enabling them to live on the land. Although they are not born with these organs, they develop them during the metamorphosis. Air is taken in through the nasal passage or the mouth, it then crosses the palate to the trachea, where the glottis divides the air to both bronchi, from where gas is transported to the lungs.
