Glass Frogs

This Hyalinobatrachium bergeri is one of the most common glass frogs here.  The genus Hyalinobatrachium can be distinguished (in part) by it's transparent peritoneum, allowing full view of its organs. The frogs breed on leaves overhanging streams.  The male will guard clutches to prevent predation (and possibly desiccation) until they hatch and drop into the water below.  The tadpoles are pink and often elusive, living at the bottoms of fast moving streams.
