This species occurs throughout much of the Amazonian Basin, from Western Pacific lowlands, central Panama and eastern lowlands adjacent to central Panama, through the Guianas, south through the Orinoco and Caribbean regions of Colombia, Margarita Island (Venezuela), Bolivian lowlands, throughout much of Brazil, northwestern Paraguay and northern Argentina. It is not present in Trinidad and Tobago, Ecuador, Peru or Uruguay. Altitudinal range is up to 1,500m asl.
Habitat and Ecology
This taxon mainly inhabits open areas, savannahs, forests, river shorelines, and reproduces explosively in permanent and temporary waterbodies. By day, specimens hide in holes in the ground. Its presence in forests is apparently due to colonization of intervened habitats along roads and penetration tracks; it has been reported from urban areas in Bolivia. Breeding and larval development takes place in ponds. It can be found breeding in very small and shallow puddles (Lynch, 2006). Time of larvae development is 30 days. It feeds on ants and termites.
This is a very common species.
There are no major threats to this adaptable species. It is sometimes found in the international pet trade but at levels that do not currently constitute a major threat.
It is in protected areas throughout most of its range.
Considerable evidence suggests that this nominal species is composed of several biological species.
