The Nonindigenous Occurrences section of the NAS species profiles has a new structure. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. Occurrences are summarized in Table 1, alphabetically by state, with years of earliest and most recent observations, and the tally and names of drainages where the species was observed. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. References to specimens that were not obtained through sighting reports and personal communications are found through the hyperlink in the Table 1 caption or through the individual specimens linked in the collections tables.

Nonindigenous Occurrences: A single specimen was collected from West Main Canal in Yuma, Arizona in 2010 (Gilbert 2010). The species identification is not certain. Body dimensions resemble Carcharhinus cerdale, but fin placement is typical of Rhizoprionodon longurio (J. Castro, personal communication). Both species are common to upper Gulf of California.

† Populations may not be currently present.

Means of Introduction: Released by an individual.

Status: Failed.

Impact of Introduction: The impacts of this species are currently unknown, as no studies have been done to determine how it has affected ecosystems in the invaded range. The absence of data does not equate to lack of effects. It does, however, mean that research is required to evaluate effects before conclusions can be made.
