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.

Tilapia sp. Smith, 1840

Common name: unidentified tilapia

Taxonomy: available through www.itis.govITIS logo

Identification: In general, cichlids (Cichlidae) are superficially similar to sunfishes and black basses (Lepomis and Micropterus; family Centrarchidae). Cichlids can be distinguished from centrarchids by a single nostril opening on each side of the head (vs. two openings in centrarchids) and the presence of a discontinuous or two-part lateral line (vs. a continuous lateral line in centrarchids).
