The firewood catfish (Sorubimichthys planiceps) a species of South American pimelodid catfish, is the sole member of the genus Sorubimichthys.[3] Known by locals along the Amazon Basin as peixe-lenha,[4] the firewood catfish is so called because it is of little eating value and is often dried and used for firewood.[5]

Distribution and habitat

[edit]

Firewood catfish occur in the Orinoco and Amazon Basins.[6] It is normally found in whitewater high in suspended sediments.[7]

Appearance and anatomy

[edit]

This species attains about 150 cm (5 ft) in standard length.[6]

These fish change in appearance as they grow.[8] In adults, the upper jaw is extremely long, about one-third the length of the snout.[8] 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.[8] 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).[8]

Ecology

[edit]

This fish is mainly nocturnal.[6] Firewood catfish are highly predatory and feed on other fish.[7]
