Pseudacanthicus histrix is a species of freshwater ray-finned fish belonging to the family Loricariidae, the suckermouth armoured catfishes, and the subfamily Hypostominae, the suckermouth catfishes.[2] This catfish is endemic to Brazil where it occurs in the lower Amazon basin in the states of Pará and Amazonas.[1] This species grows to a total length of 90 cm (3 ft).[4] P. histrix has incredibly elongated odontodes that form a brush on the anterior margin of the pectoral fin spine in breeding males; however, sexual dimorphism has not been reported for the other Pseudacanthicus species.[5]
