I thought that was why they were such good bioindicators. I thought all frogs breathed through the skin. I thought that was why they were such good bioindicators.

While cold water has a higher dissolved oxygen content than warm water, both are still markedly lower than the oxygen content of air. Obviously, the frog has found ways to increase his rate of oxygen uptake (increased surface-to-volume ratio, thinner diffusion barrier, decreased blood flow rate, more capillaries, etc). If you've ever pithed a frog, you know that they live for hours in dry environments, even after their lungs have been disabled. The problem with removing the frog from the damp environment is that the skin is not exclusively a respiration organ. In frogs, water contact is used to maintain ionic concentrations and the resulting gradients, remove metabolic waste products from the body, and perform a variety of other functions. Not that anybody here really cares that much about cutaneous respiration... @the robot child: Yes, but not necessarily because of the most obvious seeming answer.

He's obsessed with conservation, and every time we go camping, he makes us attempt to identify animals based on their call. My science teacher would be so happy to see this news.

Their evolution shows unique physiological adaptations to their very specific environment. People generally think of pool ventilation, lung breathing, as being a marker of higher evolution, but it's not actually the most efficient method of respiration. @ the robot child: I wouldn’t necessarily say that they are “less” evolved.

For a species to be discovered to have no lungs today, doesn't mean that they just got that way yesterday. @ andrew — I’m pretty sure if you’ve dissected one, you’ve dissected them all.
