Summary:

Large oceanic fishes with brilliant silvery skin and bright red fins. Southern Ribbonfish have a long, compressed body that tapers to a very narrow tail base, large eyes, a large very protrusible mouth, and a long-based dorsal fin extending from the top of head with a high crest at the front in young. Juveniles have a large red caudal fin, and long, fan-like pelvic fins that reduce with growth to become small tubercles in adults. They also have several large black blotches or spots on the side: usually 3-4 above the lateral line, and 1-2 below.

Southern Ribbonfish occasionally enter coastal bays.

Although some authors referred to this species as Trachipterus jacksonensis, Clark's description was published before that of T. jacksonenesis (April 1881 vs May 1881).

Southern Ribbonfish, Trachipterus arawatae (Clarke 1881)

More Info


Distribution

Known in Australian waters from north Queensland to west of Bunbury, southwestern Western Australia, including around Tasmania; depth range 0-1000 m. The specimen off Bunbury was taken on hook and line. Elsewhere the species most likely circumglobal in the Southern Hemisphere,  where it is widespread in deeper oceanic waters to depths of 1000 m.

Features

Dorsal fin 145-185; Caudal fin 8 + 5; Pectoral fin 9-11; Pelvic fin 5; Gill rakers (lower limb) 10; Vertebrae 81-83.

Body long, very compressed, deep anteriorly, tapering to a very narrow tail base; eyes large, mouth very protrusible; dorsal fin long-based, extending from top of head to tail, with a high crest at the front in young, crest reducing in size and finally lost with growth; pelvic fins long and fan-like in juveniles, reduced to small tubercles in adults; anal fin absent.

Size

To 2.2 metres.

Colour

Body silver, partly transparent; juveniles with several large black blotches on either side, usually 3-4 above lateral line, 1-2 below; fins bright red.

Feeding

Feeds mostly on pelagic fishes, crustaceans and squids.

Fisheries

These fishes are most often taken in deepwater trawls, but are occasionally sighted at the ocean surface or found stranded ashore after storms.

Remarks

This species was considered a synonym of Trachipterus trachipterus (Gmelin 1789) by Heemstra & Kannemeyer (1984). Some authors refers to this species as Trachipterus jacksonensis, which was described by Ramsay based on a specimen from Manly, Sydney, New South Wales. Ramsay's description was published in May 1881, after the description of Trachipterus arawatae was published.
