## Quick answer

Glass frogs are small tree frogs of Central and South American rainforests, famous for the translucent skin on their bellies that reveals their internal organs and beating heart. They are nocturnal, arboreal, and care for their eggs on leaves above streams. Most species live around 10 to 14 years.

## Behavior and transparency

Glass frogs are named for the translucent skin on their undersides, through which the heart, liver, and digestive tract can be seen. Recent research found that some glass frogs become even more transparent while sleeping by tucking red blood cells into their liver. Their green backs help them blend with leaves by day, while they are active and vocal at night.

Even familiar animals lose ground as wild habitat keeps shrinking worldwide.
