Ecological Risk Screening Summary - Ancistrus ranunculus (a freshwater fish, no English 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.

Ancistrus ranunculus is a Brazilian, armored catfish found in the Xingu and Tocantins River basins. The history of invasiveness is uncertain as there have been no reports of this fish outside of its native range. Due to its low climate match score and absence of introduction history, the overall risk for this species is uncertain.
