Description

Pseudancistrus barbatus is an armoured catfish of the family Loricariidae from northern South America. The body is covered with bony plates and the species has a ventral sucker mouth; adult males bear a row of stout bristle-spines (odontodes) on the snout, whose length is related to rank within the population. It reaches about 20 cm and lives in rapids, where it stays in rock crevices in strong current and clings to the rocks with its sucker mouth. With its rasping mouth it scrapes off algae and aufwuchs. The species is fished locally with harpoons or bow and arrow.
