Description
The sand sea catfish is a sea catfish (Ariidae) from coastal and estuarine water of the western Atlantic, off northern South America. The species grows to about 25 cm and has a streamlined, greyish body with a flattened head and barbels. The pectoral and dorsal fins each carry a stout, serrated spine linked to venom. As a bottom-oriented omnivore it searches sand and mud bottoms for worms, crustaceans and detritus; the male broods the eggs in its mouth. A sting is very painful; handle with care.
