Researchers in Peru have discovered four new species of tiny so-called "glass frogs" (family: Centrolenidae).
Centrolene charapita: with the yellow splotches on its back, this species was aptly named after little yellow chili peppers. Their hindlegs also had fleshy little zigzag-like protuberances whose purpose is unknown.
Cochranella guayasamini: This species is mostly green with yellow encircling its eyes. Interestingly, the tadpoles begin as a reddish pink color. Since they live in streambeds that are low in oxygen, this coloration may reflect the numerous blood vessels in their skin, although that remains just a hypothesis as studies of glass frog tadpoles are rare.
Chimerella corleone: Yes, it is indeed named after the famed character from The Godfather. This tiny frog is only 2cm long and has green bones, which they suspect may arise from build-up of the green pigment in bile, biliverdin.
Hyalinobatrachium anachoretus: This new species was discovered in the cloud forest of Peru at 2,050 meters (6,725 feet), which is reportedly an unusually high altitude for other frogs in this genus.
What is currently unknown is why these species evolved transparent bodies.

Yet another proof of how adaptive organisms become over millions of years…
Hard to believe sometimes but absolutely true to me.
There is a common theme of utilizing the animals natural proteins to enhance its camouflage, in this case the green bones!
As a lover of nature it is really amazing to hear that in the century we live in with all the global warming, animal poaching and pollution with hundreds of species becoming extinct each year that there are still new species developing and being discovered making our ecosystems grow.
It truly blows my mind how adaptive species are to their environment and that species are still evolving in our modern lives.
