Description

The crucifix sea catfish (Sciades proops) is a large sea catfish of the family Ariidae from coastal waters of northern South America. The species has an elongate, greyish body with barbels and can reach about one metre. The English and Dutch names refer to the underside of the skull, which resembles a crucifix. It lives mainly in brackish estuaries and lagoons and also occurs in fresh water, on shallow muddy bottoms. The diet consists of fishes and shrimps. The dorsal and pectoral fins bear a serrated, venomous spine that can cause painful puncture wounds; the male broods the eggs in its mouth.
