All Decapterus Species: Posterior straight part of lateral line with enlarged hardened scutes ; adults of most species with pectoral fins long and falcate, shorter than head length. Scales obvious over most or all of body. No enlarged scute-like scales in curved lateral line; dorsal accessory lateral line terminating before origin of dorsal fin. Terminal ray of dorsal and anal fins consisting of a detached finlet not connected to penultimate ray by fin membrane; shoulder girdle margin with a shallow groove, a low moderate papilla above it, and a smaller papilla near upper edge (FAO 2002).

Unique Characters: Body very slender and elongate; cigar-shaped. Small black spot at edge of opercle. Last dorsal and anal fin rays separate as finlets from the rest of the fin. Conspicuous row of black spots on anterior portion of lateral line. Caudal fin yellowish. Posterior end of maxilla concave above, noticeably rounded and produced below. Straight part of lateral line usually with 0 (rarely 1 or 2) anterior scales and curved lateral line with 37-56 scales.
