In 2009, a frog was discovered in a rain forest in Ecuador that changed its skin texture from smooth to spiky, and in 2014, a new species of frog was found in Staten Island. These amphibians continue to surprise scientists, yet many species have also been going extinct for decades. For today's Please Explain, we learn about the world of frogs, with Robin Moore, an award-winning photographer, a Senior Fellow of the International League of Conservation Photographers, and an advocate with the Amphibian Survival Alliance.
