Breathing through skin in a newborn mammal

The exchange of oxygen and carbon dioxide through the skin does not occur in most mammals because they have high metabolic rates and diffusion through the skin is poor. But we have found that in the Julia Creek dunnart (Sminthopsis douglasi), a marsupial mouse with one of the smallest newborns of an...

Zusammenfassung:	The exchange of oxygen and carbon dioxide through the skin does not occur in most mammals because they have high metabolic rates and diffusion through the skin is poor. But we have found that in the Julia Creek dunnart (Sminthopsis douglasi), a marsupial mouse with one of the smallest newborns of any mammal, gas exchange through the skin is the predominant form of O2 and CO2 transfer in the first days after birth.
