Amphibians Breathe With Gill

By the time the amphibian is an adult it usually has lungs not gills.

Amphibians breathe with gill. There are a few amphibians that do not have lungs and only breathe through their skin. The reptiles lung has a much greater surface area for the exchange of gases than the lungs of amphibians. Not all amphibians can breathe underwater.

When theyre born tadpoles live a fully aquatic life and breathe through their external gills exchanging gas directly with the surrounding water until they develop internal gills. When they are adults they breathe through lungs and have four legs with interdigital membrane. 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.

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. Yes young amphibians breathe through their gills. When they hatch from their eggs amphibians have gills so they can breathe in the water.

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. Early in life amphibians have gills for breathing.

Most hatch from eggs in water. 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 are cold-blooded which means that their body temperature changes with their surroundings.

They live the first part of their lives in the water and the last part on the land. Amphibians have bare skin breathe through gills and have no legs when young. Do all frogs have gills.
