A new species of glass frog has been discovered tucked away in the Talamanca mountains.
Glass frogs can only be found in parts of Central and South America and are so translucent that their organs are visible from their underside.
This tiny, semi-translucent frog lurked out of scientists’ sight during more than a century. Now Hyalinobatrachium dianae has made its world debut in February in the taxonomy journal Zootaxa.
While H. dianae shares many characteristics of other glass frogs, the nocturnal frog’s strange call is what most distinguishes it as a separate species.
It’s advertisement call – used by male frogs to attract females for mating – is quite unique. It’s different than any other species that has been discovered. H. dianae’s advertisement is a long metallic whistle with rapid pulses, similar to an insect’s call.
