Description

Pseudauchenipterus nodosus is a scaleless catfish (family Auchenipteridae) of north-eastern South America. The species reaches about 22 cm and has a streamlined, silvery-grey body with barbels. It lives over muddy bottoms in brackish river mouths and probably prefers large rivers and slightly brackish water. Notably it occurs in very dense schools over muddy bottoms. It is an omnivore with a tendency towards detritivory. Reproduction involves internal fertilisation, for which the male has a modified anal fin. The species is of modest commercial value and is harmless to humans.
