Summary:
A bluish-green to yellowish-green trevally becoming silvery below with 5-7 broad, vertical dusky bars along the sides, and often inconspicuous golden spots above the level of the pectoral fin. The soft dorsal and anal fins are yellowish-green with white tips on the lobes, the caudal fin is yellowish-green with a narrow dark margin, and the pelvic fins are whitish to clear.
The barred pattern is more pronounced in juveniles, which sometimes shelter among the tentacles of large pelagic jellyfish.
