Silvery body, often with a darker bluish-grey dorsal surface and a lighter, sometimes yellowish, ventral side. Fins are typically dusky or yellowish, with the caudal fin often having a darker margin. Juveniles may exhibit faint vertical bars.

Scale type

cycloid

Mouth position

terminal

Distinctive features

Deeply compressed, ovate body shape., Small, embedded scales., Forked caudal fin with pointed lobes., Absence of scutes along the lateral line (distinguishing feature from some other carangids)., Short, blunt snout.

Dorsal fin

Two dorsal fins; the first with 6-7 short, stout spines, the second with 1 spine and 23-27 soft rays. The anterior rays of the second dorsal fin are elongated in adults.

Tail fin

Deeply forked, with long, pointed lobes.

Pectoral fin

Identification Tips

1. 1

   Body Shape

   Look for the distinctly ovate and compressed body, which is deeper than many other Trachinotus species.

2. 2

   Fin Structure

   Note the elongated anterior rays of the second dorsal and anal fins in adults, and the deeply forked caudal fin.

3. 3

   Coloration

   The overall silvery body with a darker back and sometimes yellowish fins is characteristic. Absence of prominent dark spots or bars (though juveniles may have faint ones).

4. 4

   Lateral Line

   The lateral line is smooth and lacks scutes, which helps differentiate it from some other carangid species.
