Whose discovery showed that frogs can breathe through their skin?
Quick Answer
This is closely associated with physiologist August Krogh, who helped demonstrate the importance of cutaneous respiration in amphibians. Frogs and many other amphibians can absorb oxygen through their skin, especially in water or at rest.
The Full Story
The role of skin breathing in amphibians is strongly associated with Danish physiologist August Krogh, who won the 1920 Nobel Prize in Physiology or Medicine. His work helped show how gas exchange can occur through moist skin, an important adaptation in frogs and salamanders. Amphibians use both lungs and skin for respiration, and in some species the skin does a large share of the work. Because amphibian skin must stay moist, it also makes them especially sensitive to pollution and dehydration.
