Glass frogs have abdomens as transparent as glass. You can clearly see their internal organs and feel their heartbeats.

The glass frog is transparent for its own safety. When they are awake, they can actively hide from predators; but when they are sleeping and most vulnerable, they have adapted to remain hidden.

Glass frogs are able to "concentrate" or hide almost 90% of the red blood cells in their livers while they sleep, and can also shrink and flatten most of their internal organs.
Nature's master of camouflage, this is a very magical and dynamic form of camouflage.

What is the highest level of disguise? The glass frog gave his answer.
When darkness gradually descends on the tree crown branches, this ghost in the forest begins to wander around at night.
