Ecological Risk Screening Summary - Metynnis longipinnis (a fish, 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.

Metynnis longipinnis is a freshwater fish native to Brazil and Venezuela. It is not known to be introduced outside of its native range, which makes its history of invasiveness uncertain. Members of the Metynnis genus (species uncertain) have been collected beyond their native range in Florida, where their status is listed as locally established. M. longipinnis has a low climate match with the contiguous United States. There is very little information available on this species and the taxonomy of the genus is unresolved, which makes the certainty of this assessment low. Overall risk for this species is uncertain.
