Glass Frogs or Glassfrogs is the common name for the frogs of the amphibian family Centrolenidae (order Anura). 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.
Transparency is a trait shared by all living glass frogs. In some species though, such as the Condor Glass Frog (Centrolene condor), the ventral peritoneum is white anteriorly, obscuring thus the heart and liver.
