The Eiffinger’s tree frog (Kurixalus eiffingeri), found on Ishigaki and Iriomote islands in Japan, has a unique biological adaptation: its tadpoles do not defecate during their early developmental stages. This finding by researchers at Nagoya University in Japan contributes to our understanding of how these small frogs survive in the tiny bodies of water where they spawn. The findings were published in the journal Ecology.
