Summary:

A distinctive striped catfish with an eel-like body and mouth surrounded by 4 pairs of barbels. The stripes become less distinct in adults. Brightly-striped juveniles often form dense schools of hundreds of individuals that appear to move as one.

The serrated dorsal and pectoral-fin spines are highly venomous and can inflict a very painful wound.

More Info


Distribution

Found in tropical and subtropical waters of Australia from the Perth region, Western Australia, around the tropical north to Sydney, New South Wales; also at Lord Howe Island, Elizabeth and Middleton Reefs, Norfolk Island, Ashmore Reef in the Timor Sea, Rowley Shoals in Western Australia, and Christmas Island in the Indian Ocean. Elsewhere widespread throughout the tropical Indo-West Pacific. The Striped Catfish was recently recorded from the Mediterranean Sea.

Striped Catfish inhabit coral and rocky reefs, estuaries, tied pools and areas along the coast in depths of 0-76 m. This is the only species of catfish to occur on coral reefs.

Features

Dorsal fin I, 85-105; Anal fin 70-81.

Size

To 32 cm TL

Colour

Head and body dark brown to greyish-brown with two pale stripes along the sides.The stripes become less distinct in large adults.

Feeding

Carnivore - feeds mostly on benthic invertebrates such as crustaceans, molluscs, polychaete worms - and the occasional fish. Individuals search for food in sandy bottoms.

Biology

The sexes are separate and fertilisation is external. Although females lay demersal eggs, the larvae are planktonic.

While adults are usually solitary or form small groups, juveniles are usually seen in dense ball-shaped schools, sometimes containing hundreds of individuals.

Fisheries

Fished many parts of its range. Taken as bycatch in Australia and caught by recreational anglers.

Remarks

Striped Catfish must be handled with extreme caution. The sharp serrated fin spines are highly venomous and rare fatalities have occurred. People may also develop secondary infections if the spine tips break off in a wound.

Etymology

Plotosus is from the Greek plotos meaning "swimming". The species is named lineatus in reference to the stripes along the body.
