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.
The history of invasiveness is uncertain. There were no records of introductions of Apteronotus leptorhynchus but it could not be determined if that was more likely due to a lack of introductions or a general lack of information. This species may be present in the aquarium trade but there was not enough information available to determine the length of time or at what volume it has been in trade. The climate match is low; only the southern tip of Florida has a medium match. The certainty of assessment is low due to a general lack of information. The overall risk assessment category is uncertain.
