Glass Frog Definition
The glass frog is a unique and fascinating group of small, semi-transparent frogs belonging to the family Centrolenidae. They are named “glass frogs” because of their translucent skin, which allows you to see their internal organs, including their heart and digestive system, through their belly.
Glass Frog General Characteristics & Facts
General Characteristics of Glass Frogs:
One of the most distinguishing features of glass frogs is their translucent skin on the ventral side of their bodies, which allows you to see their internal organs, including their heart, liver, and digestive system.
Glass frogs are relatively small, with adults typically ranging from 0.8 to 3 inches (2 to 7.5 centimeters) in length.
Coloration: They often have bright green or lime-colored skin on their dorsal side, which provides camouflage in the lush green environments where they live.
Glass frogs have large, bulging eyes that contribute to their excellent vision and enable them to be active during the night.
They have partially webbed feet that help them in their arboreal (tree-dwelling) lifestyle, as they are skilled climbers.
Glass frogs are known for their distinctive vocalizations, which they use for communication, especially during the breeding season.
