Threadfin Leatherjacket, Paramonacanthus filicauda (Günther, 1880)
Thousands of juvenile Threadfin Leatherjackets washed up on New South Wales beaches in May and June 2004. Mass kills of this species have been recorded in New South Wales and Queensland in previous years.
The Threadfin Leatherjacket is greenish brown above and pale below. It has scattered brown spots on the head and body. There are small brown spots on the caudal fin.The upper two caudal fin rays are often elongate, producing a filament that is slightly shorter than the head length.
The species is found in tropical and temperate inshore marine waters in depths between 5 m and 125 m.
The species is found in Australia and Papua New Guinea. In Australia it is known from the north-western coast of Western Australia, around the tropical north of the country and south to Tasmania.
