Introduction

The Finny Scad can be recognised by the long pectoral fin, by the prominent scutes and large black spot on the top of the operculum (gill cover). It is widely distributed in the Indo-Pacific.

Identification

The Finny Scad is a streamlined, countershaded fish which resembles other fishes in the Family Carangidae (trevallies, scads etc). The Finny Scad can be recognised by the long pectoral fin, by the prominent scutes (51-59) on the straight part of the lateral line on the side of the body, by the large black spot on the top of the operculum (gill cover) by the dorsal (7-9) and anal (8-10) finlets, and by the adipose eyelid which covers the pupil except a narrow vertical slit over the pupil.

Distribution

The Finny Scad has a wide distribution in the Indo-Pacific.
