It breeds in temporary pools (A. Fouquet, pers. comm. 2008).
There are no obvious ecological differences with Rhinella margaritifera (A. Fouquet, pers. comm. 2008).
This is likely an abundant species (A. Fouquet, pers. comm. 2008).
The region where the species occurs is quite pristine but regional threats are forest clearing and gold mining (A. Fouquet, pers. comm. 2008).
