Save the Amphibians. The $40-million-a-year trade in frog legs could be spreading pathogens that are killing off amphibian populations, scientists report. Researchers said that disease spread through poorly regulated amphibian trade probably posed a greater risk to amphibian biodiversity than overharvesting. The American bullfrog, pictured here, is one of the many species used in the frog-leg trade. Photo: Mehgan Murphy/Smithsonian’s National Zoo (via Science in Pictures - The New York Times)
