Glass Frog

The glass slipper, er, frog!

Class: Amphibians
Order: Frogs

Family: Glassfrogs

Before you scroll down the page, we should warn you: it’s about to get a little gross! The glass frog is completely normal and green from above, but from below, you can see all its organs: its liver, its heart, its intestines, everything! Why? Camouflage! Without a clear silhouette, it’s hard to see this frog.
