Amphibians Breathe With Gill

Many young amphibians also have feathery gills to extract oxygen from water but later lose these and develop lungs.

Amphibians breathe with gill. The mouth closes the gill cover opens and the water is pressed out of the body together with the carbon dioxide as a by-product see picture. They can now breathe air on land. Most amphibians begin their life cycles as water-dwelling animals complete with gills for breathing underwater.

No matter how big or small the mammal is they always use their lungs to inhale oxygen and exhale carbon dioxide. In addition some species of fully aquatic salamanders which have gills dont grow lungs either. The gills lie behind and to the side of the mouth cavity and consist of fleshy filaments supported by the gill arches and filled with blood vessels which give gills a bright red colour.

A few amphibians dont bother with lungs and instead absorb oxygen through their skin. Frogs and toads. Within a few days of life the external gills of tadpoles are covered by a fold of tissue called the operculum which leaves only one or two small openings to the outside known as spiracles.

There are three main groups of amphibians. In addition they undergo metamorphosis that is they go through different phases of life mainly three. By the time the amphibian is an adult it usually has lungs not gills.

The lungs of amphibians are simple saclike structures that internally lack the complex spongy appearance of the lungs of birds and mammals. When they are adults they breathe through lungs and have four legs with interdigital membrane. Do all frogs have gills.
