This species' geographic range is from the Chacoan region of Argentina, Bolivia, Brazil, and Paraguay. It has an altitudinal range of up to 700m asl.
Habitat and Ecology
It is a fossorial species. It breeds explosively during the first heavy rains of the year. In Cordoba, Argentina, it does not reproduce every year. The eggs are scattered on the bottom of the ponds and it adapts well to anthropogenic disturbance.
It is a common species, but it is seldom found during the dry season. It is declining in the southern portion of the range due to persecution.
Local human populations persecute this species because of unfounded beliefs that it is venomous. It is also collected for the international pet trade. Eggs are sold internationally for scientific research.
It occurs in several protected areas.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, tolerance of a broad range of habitats, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
