Amphibians Breathe With Gill

Not all amphibians can breathe underwater.

Amphibians breathe with gill. They live the first part of their lives in the water and the last part on the land. Yes young amphibians breathe through their gills. Most amphibians begin their life cycles as water-dwelling animals complete with gills for breathing underwater.

Amphibians are a class of animals like reptiles mammals and birds. The oxygen is absorbed from the water by the lamellae. The lungs of amphibians are simple saclike structures that internally lack the complex spongy appearance of the lungs of birds and mammals.

They lay eggs in water not on land and their eggs are soft with no hard shell. For a time tadpoles have both lungs and gills. As amphibian larvae develop the gills and in frogs the tail fin degenerate paired lungs develop and the metamorphosing larvae begin making excursions to the water surface to take air breaths.

There are three main groups of amphibians. As the tadpole ages the gills disappear and legs begin to grow18 June 2008. Just like most amphibians the different salamander species breathe through a membrane in their throat and mouth skin lungs and gills.

Yes amphibians can smell. 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. Most amphibians begin their life cycles as water-dwelling animals complete with gills for breathing underwater.

When they hatch from their eggs amphibians have gills so they can breathe in the water. They have gills and tails but no legs. When they are adults they breathe through lungs and have four legs with interdigital membrane.
