Description

Aspistor quadriscutis is a sea catfish of the family Ariidae from coastal waters of eastern South America. The species has an elongate, greyish body with barbels and a bony armoured head shield, and lives on muddy bottoms of turbid estuaries, mangrove lagoons and the lower reaches of rivers, tolerating strongly varying salinities. As a bottom dweller it feeds on benthic animals, crustaceans and small fishes. The dorsal and pectoral fins bear a serrated, venomous spine that can cause painful puncture wounds. Like other sea catfishes the male broods the relatively large eggs in its mouth. The species is of local fishery importance.
