Description

The estuary catfish is an eeltail catfish (Plotosidae) from the waters around southern Australia. The species has a robust, elongate, scaleless body with a large head, barbels and a continuous fin margin around the tail. It lives inshore in shallow bays and sandy inlets near river mouths. As a bottom hunter it feeds on crustaceans, molluscs, worms and small fishes. The dorsal and pectoral fin spines carry venom; a sting causes intense pain.
