Description
The eel-tailed catfish, also called dewfish, is a catfish (Plotosidae) from fresh water of eastern Australia. The species grows to about 90 cm and has a stocky forebody with barbels that merges into an elongate, eel-like rear body, where the dorsal, tail and anal fins fuse into a continuous margin. As a bottom-dweller it searches rivers and lakes for crustaceans, molluscs, insects and small fish; the male guards a gravel nest. The stout, serrated dorsal and pectoral spines are venomous and can give a very painful puncture wound.
