Issue
See Mees (1987: 186) for detailed description. Friel (1994: 86) removed this species from Aspredo to preserve monophyly of that genus.

Occurs mainly in brackish water. Found on soft bottoms of shallow turbid water near river mouths. Reported to migrate from estuary into freshwater, but actual spawning apparently takes place in brackish water (Ref. 6868). The species has a peculiar mode of egg incubation wherein the female banjo catfish carries the eggs firmly attached to the underside of the body. This seems to be an adaptation to facilitate the oxygenation of the eggs in muddy environments. Reproduction probably occurs during the earlier part of the year (Ref. 35381).
