While the general background coloration of most glass frogs is primarily lime green, the abdominal skin of some members of this family is translucent. The internal viscera, including the heart, liver, and gastrointestinal tract are visible through this translucent skin, hence the common name.
Glassfrog. They are amazing transparent frogs that are found in Central and South America. They are nocturnal and live in the tree canopy, rarely venturing low; although some do make their homes closer to the ground, living in the vegetation around small forest streams.
