Ecological Risk Screening Summary - Typhlobelus ternetzi (a catfish, no common name) - Uncertain Risk

Species that are considered uncertain risk need a more in-depth assessment beyond the Risk Summary to better define the species’ risk to U.S. environments.

Typhlobelus ternetzi is native to South America and has been found in the Upper Negro River basin in Brazil. Fish belonging to the genus Typhlobelus are generally psammophilic (loose sand) in preference for habitat. There is no information or documentation on introductions outside of its native range; therefore, the history of invasiveness is uncertain. T. ternetzi has a low climate match within the contiguous United States. Due to lack of information the certainty of assessment is low. The overall risk assessment category for this species is “uncertain”
