Current Population Trend:Stable
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

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.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): 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.
