The Golden Eyed Tree Frog lives in the trees in tropical rain forests in South America. Its a nocturnal species, only moving around at night.

Following heavy rains during the rainy season, the male frogs gather at temporary or permanent water bodies to call out to attract the female frogs. The male frogs have paired vocal sacs that inflate comically large when they are calling. The female frogs can lay between 600 – 1000 eggs. The eggs hatch into tadpoles.

The International Union for the Conservation of Nature (IUCN) Red List assesses the Golden Eyed Tree Frog as Least Concern for Extinction. The species has a large range and are thought to be common throughout it. There are currently no major threats to the frog.
