It has an elongated body with two separate dorsal fins. The back is yellowish-grey, while the belly is white to silvery. The caudal fin is yellow, with a black upper and trailing edge. A dusky band extends from the snout through the centre of the eye, above the pectoral fin base, and along the body to the caudal peduncle.
It looks like Sphyraena flavicauda (Yellowtail barracuda), which is similar in size and appearance to Sphyraena chrysotaenia. Distinguishing features include subtle differences in fin coloration, scale counts, and gill raker characteristics.
