Translucent Glass Frog

The world’s first naturally fluorescent frog has been discovered in Argentina by scientists at the Bernardino Rivadaiva Natural Sciences Museum. They made the discovery while studying the metabolic origin of pigments in a tree-frog species common to South America. Under normal light, the animal’s translucent skin is a muted yellowish-brown color with red dots, but under ultraviolet light, it turns a celestial green.

“We were very excited. It was quite disconcerting. [It] radically modifies what is known about fluorescence in terrestrial environments, allowing the discovery of new fluorescent compounds that may have scientific or technological applications [and] generates new questions about visual communication in amphibians,” said researcher Julian Faivovich.
