Longnose Trevally
Carangoides chrysophrys (Cuvier, 1833)
A Longnose Trevally at a depth of 20m, North Solitary Island, New South Wales, January 2000. View larger image.
The Longnose Trevally is silvery to blue-green above and silver below. It has a black spot on the upper operculum (diagram of fish parts) and a long pectoral fin that reaches to the straight portion of the lateral line. This species also has a blunt snout which gives it one of its common names, the Club-nosed Trevally.
The Longnose Trevally has a widespread distribution on coastal reefs throughout marine waters of the Indo-west Pacific.
In Australia it is recorded from tropical waters of the central coast of Western Australia, around the north of the country, and south to northern New South Wales. Small juveniles are sometimes seen as far south as Sydney, presumably carried south by the east Australian current.
This species grows to 60cm in length.
The Longnose Trevally can be distinguished from several similar species by a combination of characters including the scalation of the breast (naked area of breast does not extend above the pectoral fin), the number of gill rakers (21-24) and fin ray counts (Dorsal 19-20, Anal 15-16).
