Glass Frogs

Ranging from southern Mexico to northern Argentina, there are nearly 140 known species of glass frog. Costa Rica hosts 13 species--2 of them rediscovered by Kubicki more than 50 years after they'd previously been spotted by scientists. Glass frogs are difficult to study because, for one thing, they're hard to see, even right in front of your nose. Their skin--clear as glass on their bellies (with bones and organs on full display) and translucent green on their backs--gives the animals a ghostly appearance. Against a green leaf, where the frogs spend much of their time, they virtually vanish.
In addition, glass frogs are nocturnal and tend to hang out above mountain streams among overhanging leaves and branches, often in dense primary forest.
these translucent frogs are native to Central and South America.
