Distribution: Throughout South America and to the east of the Andes.

Habitat: Open formations, in savannas, fields, pastures, edges of riparian and gallery forests, lakes, ponds, meadows, and swamps.

Habits: Crepuscular, nocturnal, terrestrial, and aquatic. Usually found in the low to mid-size vegetation, such as grasses and herbaceous plants in floodplains and swamps.

Diet: Insects, arthropods and other amphibian species.

Breeding: Oviparous, spawning on the surface of the water. Females care for both the eggs and the tadpoles. Males vocalize around bodies of water, whether temporary or permanent. The couple lays eggs in a foam nest, and they usually also open canals, interconnecting puddles, thus preventing the tadpoles from getting stuck and dying from dehydration.
