Biology
Glass frogs are mostly arboreal. They live along rivers and streams during the breeding season, and are particularly diverse in montane cloud forests of Central and South America, although some species occur also in Amazon and Chocóan rainforest and semi-deciduous forests.
The eggs are usually deposited on the leaves of trees or shrubs hanging over the running water of mountain streams, creeks, and small rivers. One species leave its eggs over stones close to waterfalls. The method of egg-laying on the leaf varies between species. The males usually call from leaves close to their egg clutches. The eggs are less vulnerable to predators than those laid within water, but are affected by the parasitic maggots of some fly species. As a result, some glass frogs show parental care. After they hatch, the tadpoles fall into the waters below. The tadpoles are elongated, with powerful tails and low fins, suited for fast flowing water. Outside of the breeding season some species live in the canopy.
