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.
Pygocentrus palometa is a species of piranha native to the Orinoco River basin in Venezuela. Little information is available about this species. It has not been introduced outside its native range, so the history of invasiveness is uncertain. P. palometa has a low climate match to the contiguous United States. However, the climate match is based on a description of the type locality, rather than reported occurrences, which were not available. Certainty of assessment is low due to a lack of information and taxonomic uncertainty. Given all factors, the overall risk assessment for P. palometa is uncertain.
