Description
The Threadfin sea catfish is a sea catfish (Ariidae) from coastal and brackish water of South and Southeast Asia. The species grows to about 40 cm and has an elongate, greyish body with barbels around the mouth. As a bottom-dweller it searches turbid coastal and estuarine water for worms, crustaceans and small fish; the male broods the eggs in his mouth. Before the dorsal fin and each pectoral fin stands a stout, venomous spine that causes a painful wound; handle with care.
