Current Population Trend: Unknown
Habitat and Ecology (see Appendix for additional information)
This species is an anuran-eating snake, which is active throughout the year. The species is found in the
Caatinga dry forests of Brazil and is reportedly a habitat generalist.
Systems: Terrestrial
Threats
Although there has been a great deal of habitat degradation of the natural Caatinga habitat as a result
of expanding urbanization and agriculture, this species is reportedly a habitat generalist, and no reports
of habitat loss or degradation as a direct threat to the species are known.
Conservation Actions
There are currently no conservation measures in place or needed for this species.
