A tadpole is the larval stage in the biological life cycle of an amphibian. Most tadpoles are fully aquatic, though some species of amphibians have tadpoles that are terrestrial. Tadpoles have some fish-like features that may not be found in adult amphibians such as a lateral line, gills and swimming tails. As they undergo metamorphosis, they start to develop functional lungs for breathing air… WebModern amphibians are characterized by the flexibility of their gaseous exchange mechanisms. Amphibian skin is moistened by mucous secretions and is well supplied with blood vessels. It is used for respiration to varying degrees. When lungs are present, carbon dioxide may pass out of the body across the skin, but in some salamanders there are no …

WebThen, the water moves into the gills which contain small membranes called as lamellae. The lamellae extract oxygen from the water and the oxygen is diffused into the bloodstream. Tadpoles can also rise to the surface and gulp oxygen from the air. As the tadpole matures, the gills are absorbed by the body and new respiratory organs are grown.
