About the Plantation Glass Frog

Hyalinobatrachium colymbiphyllum, also called the bare-hearted glass frog, plantation glass frog and the cricket glass frog, is a species of frog in the family Centrolenidae that is found in moist forests, often near streams, in countries in Central America and South America. They are small, green frogs with many similarities to other glass frogs, however, they have the most transparent undersides of any glass frogs. Their transparent undersides make them ideal bio-indicators for how global warming and other threats are affecting the animals in the forests.

Bare-hearted glass frogs are similar in features to most glass frogs but have their own distinct characteristics. Like most glass frogs, they are small and green with yellow spots and transparent undersides. The transparent undersides are the main feature of most glass frogs, but the bare-hearted glass frog has the clearest underside, allowing almost full visibility of their internal organs. Their transparent skin also makes them difficult to see, as well as their size. They are very small, with male frogs being 22–27 mm (0.87–1.06 in) long and females 24.5–29 mm (0.96–1.14 in) long.
