All frogs start life as aquatic tadpoles, breathing underwater through internal gills and their skin. Then later most develop into land animals with lungs for breathing air. But in all stages breathing is controlled by pulsing the throat. Most frogs loose their gills when they metaorphise.

Frogs can also breath through their skin, with tiny blood vessels, capillaries, under the outer skin layers. The African 'Hairy' frog, Trichobatrachus robustus, has small lungs and during breeding seasons the males get hair like projections on their back legs. This is because of the high oxygen needs at this time.

When the frog is out of the water, mucus glands in the skin keep the frog moist, which helps absorb dissolved oxygen from the air. A frog may also breathe much like a human, by taking air in through their nostrils and down into their lungs.

When breathing, the frog will keep its mouth closed. Air is then drawn through the nostrils to the lungs. This action is caused by the movement of their pulsing throat. Body contractions enable them to release carbon dioxide. When a frog fills its lungs with air, it enhances its buoyancy when back in the pond.

A. Most frogs and toads breathe (and take in moisture) through their skin through a process called cutaneous gas exchange, but they also have lungs with which they breathe. During the time they stay submerged under water or buried in soil (such as during hibernation) they ONLY breathe through their skin.

Large animals which breathe through their skin also use blood to transport oxygen to their tissues and to bring carbon dioxide to the surface of the body. This means that the blood vessels must come very close to the skin. With a microscope it is possible to see the tiny blood vessels called capillaries.
