Paraguay, southern Brazil, Bolivia, and northern Argentina
The native range of the yellow anaconda is concentrated within the subtropical regions of central South America. Specifically, established occurrences are documented across Paraguay, Bolivia, northern Argentina, and the southern portions of Brazil. This geographical positioning is fundamental to understanding the species' ecological boundaries and habitat specialization within the continent.
