The driftwood catfishes are catfishes of the family Auchenipteridae.
The two genera of the family Ageneiosidae have been placed here, resulting in a grouping of about 60 species in about 19 genera.[1]
These fish are found in rivers from Panama to Argentina.[1] They are commonly found in river flood plains.[2]
All but one species have three pairs of barbels, with the nasal barbels absent. The adipose is rarely absent, but is very small.[1] While Ageneiosus inermis is known to reach 59 centimetres in length, most are small, with some species not known at any longer than 3 cm.[1] Internal insemination is probable for all species.[1]
Auchenipterids are nocturnal. Some of the smaller species are known to hide in logs and crevices during the day and come out to feed during the night. Some larger species can consume fruits and insects and are probably omnivorous. Fish of this family seem to feed primarily on insects, but fish, shrimp, fruit, and even filamentous algae and other plant material may be consumed, at least occasionally.[2]
