Partially translucent 'glass frog'
The 'glass frogs' of Central America and the Amazon belong to a family of more than 10 genera and around 150 species. These frogs, green on their dorsal part, have a translucent chest and abdomen hence their nickname. Their lungs, intestines, eggs, and even their heartbeat can be seen through their skin.
