Not all amphibians can breathe underwater.
Amphibians breathe with gill. 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. In addition some species of fully aquatic salamanders which have gills dont grow lungs either. An amphibian is a vertebrate an animal with a backbone.
They also have fins to help them swim just like fish. As the tadpole ages the gills disappear and legs begin to grow18 June 2008. Do all frogs have gills.
The lungs of amphibians are simple saclike structures that internally lack the complex spongy appearance of the lungs of birds and mammals. They spend part of their lives in water breathing with gills and part of their lives on land breathing with lungs. Amphibians are a class of animals like reptiles mammals and birds.
Most amphibians begin their life cycles as water-dwelling animals complete with gills for breathing underwater. Many young amphibians also have feathery gills to extract oxygen from water but later lose these and develop lungs. Do amphibians breathe through lungs.
Tadpoles are frog larvae. 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. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin.
Frogs like salamanders newts and toads are amphibians. The larvae live in water and breathe using their gills. Frogs and toads.
