Aspredo aspredo   (Linnaeus, 1758)
Family:	Aspredinidae (Banjo catfishes) , subfamily: Aspredininae			picture (Asasp_u3.jpg) by Friel, J.P.
Order:	Siluriformes  (catfish)
Class:	Actinopterygii (ray-finned fishes)

Environment:	demersal
Climate:	tropical

Distribution:	Central and South America: lower portions of coastal rivers from Venezuela to northern Brazil.
Biology:	Benthic fish occurring on sandy-muddy bottoms of brackish waters (Ref. 35381) and coastal rivers (Ref. 36695). Found on soft bottoms of shallow turbid water near river mouths. 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)
Threatened:	Not Evaluated, see IUCN Red List  , (Ref. 36508)
Dangerous:	harmless
