If so, we must determine what can be done about it. Perhaps it is not an anthropogenic contaminant at all. The fungus appears to impact the skin, resulting in the laying down of extra layers of keratin, thus impacting transdermal respiration. The questions just continue to build. Possible interrelations among environmental toxicants, amphibian development, and decline of amphibian populations.
Amphibian deformities continue to puzzle researchers.
