Description

Graeffe's catfish is a sea catfish (Ariidae) from Australia and New Guinea. The species grows to about 60 cm and has a streamlined, scaleless body with barbels and stout, serrated pectoral and dorsal fin spines. It is remarkably salt-tolerant and inhabits freshwater rivers and lagoons, brackish estuaries and coastal waters, at temperatures from 11 to 38 degrees. As an omnivore it searches the bottom for invertebrates, small fishes and plant matter. The male incubates the eggs in its mouth. The pectoral and dorsal fin spines are venomous and give a painful puncture wound.
