Description

The false-spine eeltail catfish is an eel-tailed catfish (Plotosidae) from fresh water of inland river systems in northern Australia. The species grows to about 25 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 nocturnal bottom-dweller it searches turbid rivers and pools for insect larvae, molluscs and crustaceans. The stout, serrated dorsal and pectoral spines are venomous and can give a painful puncture wound.
