Fleischmanns Glass Frog, El Valle, PanamaThere are quite a few different species of glass frogs that live in Central and South America. They are very small and most are green with a translucent belly. Viewed from below, you can see the internal organs — thus the name. This guy, the Fleischmann’s or northern glass frog, photographed in the El Valle region of Panama, can be distinguished by the faint yellow spots on its back.
