Justification: Anodontites trigonus has been assessed as Data Deficient. Despite it being widely distributed throughout South and Central America, there is insufficient data about the population and habitat. As this species is experiencing localised declines and even localised extinctions, further research is recommended in order to accurately assess and elevate this species to a higher category.

Threats [top]

Major Threat(s):	It is unknown whether this species is impacted by any major threats. It is possibly threatened with extinction in Rio Grande du Sul, Brazil, but it is unknown what is causing this decline (Castillo et al. 2007). It is likely that this species is experiencing localized declines due to urbanization, habitat degradation and laterations to the hydrological regime. This species has become extinct in Rio la Plata, due to similar conditions currently present in Rio Grande du Sul (G. Pastorino and G. Darrigran pers. comm. 2010).
