Description

Butler's eeltail catfish is an eeltail catfish (Plotosidae) from coastal waters of northern Australia and New Guinea. The species grows to about 33 cm and has an elongate, dark body with a long anal and dorsal fin joined to the tail and four pairs of barbels. The pectoral and dorsal spines are linked to powerful venom glands; a sting is very painful and dangerous. As a bottom-dweller it searches around reefs and on sand and mud bottoms for invertebrates and small fish. Do not touch; handle with care.
