Introduction

The Longnose Trevally is silvery to blue-green above and silver below. 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.

Identification

The Longnose Trevally is silvery to blue-green above and silver below. It has a black spot on the upper operculum 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 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).

Habitat

It occurs near coastal reefs.

Distribution

The Longnose Trevally has a widespread distribution 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.
