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.

Sorubimichthys planiceps (Spix and Agassiz, 1829)

Common name: firewood catfish

Synonyms and Other Names: Shovelnose catfish.

Taxonomy: available through www.itis.govITIS logo

Identification: This large size leatherskin catfish can reach more than 1.5 m (4.9 ft). The body is extremely elongated and round, with a flat head and round snout proportionally larger than the rest of the body – adorned with long barbels. Coloration is dark gray, which a long narrow clear section extending from the pectoral to the caudal fins. Typically the dorsal region and fins are covered with dark spots. Lundberg et al. (1989) reviewed the taxonomy of Sorubimichthys and identified two nominal species: S. spatula (from a single specimen that is now destroyed) and S. planiceps.

Size: to 150 cm SL

Native Range: Native to the Amazon and Orinoco River basins (Lundberg et al 1989).

† Populations may not be currently present.


Ecology: Mainly nocturnal. Feeds primarily on small fishes and invertebrates (Lundberg and Littmann 2003).

Means of Introduction: Aquarium release.

Status: Failed in California.

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.

Remarks: Sorubimichthys planiceps has been listed as 'vulnerable to extinction' in the Orinoco River basin due to urbanization, development, and habitat destruction (Barletta et al. 2010).
