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.
Serrasalmus neveriensis is a piranha native to the coastal rivers of Venezuela. S. neveriensis was described relatively recently (1993), and very little is known about the species. No evidence of trade in this species was found. Numerous U.S. states prohibit the possession or trade of piranhas. No introductions have been reported outside the native range, therefore, history of invasiveness is No Known Nonnative Population. No georeferenced occurrence records were available, so the climate matching analysis was based on a verbal description of the type locality. The climate match to the contiguous United States was low overall, with medium match only in the southernmost areas of Florida and Texas. Certainty of assessment is low because of the lack of information. Given the lack of introduction history and the low climate match to the contiguous United States, overall risk posed by S. neveriensis is Uncertain.
