Description

The Tete sea catfish is a sea catfish (Ariidae) from the eastern Pacific. The species has a silvery-grey, streamlined body with a high, shark-like dorsal fin and barbels. It is common in coastal seas and brackish water and ascends the middle and lower reaches of rivers to about 25 m above sea level. As an omnivore it searches the bottom with its barbels for crustaceans, molluscs, worms and small fishes. The male incubates the large eggs in its mouth. The pectoral and dorsal fin spines are venomous and give a painful puncture wound.
