How the Weeping Frog lives

It lives on the ground in low grasslands that can flood. In an Argentine soybean field, it was recorded eating ants and common pill woodlice. Its breeding is linked to heavy rain. Males call while floating on the water surface.

Sources and how we check

We check each fact against its source. The illustrations simplify how the real animal looks.

The classification (class, order, family, genus) follows Wikidata records, checked against GBIF. Classifications can change as research goes on.

The basic data are the values given in each source. They vary with how the animal is measured, whether it is male or female, and whether it lives in the wild or in captivity.
