The firewood catfish (Sorubimichthys planiceps) a species of South American pimelodid catfish, is the sole member of the genus Sorubimichthys. [2] Known by locals along the Amazon Basin as peixe-lenha, [3] the firewood catfish is so called because it is of little eating value and is often dried and used for firewood. [4]
Firewood catfish occur in the Orinoco and Amazon Basins. [5] It is normally found in whitewater high in suspended sediments. [6]
This species attains about 150 cm (5 ft) in standard length. [5]
These fish change in appearance as they grow. [7] In adults, the upper jaw is extremely long, about one-third the length of the snout. [7] The dorsum is ash-gray with darker spots. The sides have a white band, bordered below by a dark gray or brown band. The venter is usually white with some large spots. The dorsal fin and adipose fin are spotted. [7] However, in juveniles, the snout is short and the pectoral fins are large and rounded. The white band does not appear until the fish is about 40 0m (1.6 in).[ clarification needed] The full adult color pattern and fin shapes appear by at least 20 cm (8 in). [7]
This fish is mainly nocturnal. [5] Firewood catfish are highly predatory and feed on other fish. [6]
