Description
Ageneiosus inermis, called manduba in South America, is a scaleless catfish (family Auchenipteridae) of the tropical part of the continent. The species grows to about 65 cm and has an elongate, silvery-grey body with short barbels and, unlike many catfishes, without strong fin spines. It prefers vegetated, quiet parts of rivers and is reported to be nocturnal. It is a predator that hunts fishes and crustaceans. Reproduction involves internal fertilisation, for which the male has a modified anal fin. The flesh is highly esteemed, making the species an important food fish.
