Pectoral fins elongate and fan-shaped with distinctive pigmentation; no dorsal midline pigment; distinct pattern of bars in pelagic juveniles. Pigmentation: Preflexion: initially, dorsolaterally on gut, patch over mid- and hindbrain, on anterior margin of lower jaw, covering pectoral fin blade (heaviest at margin), 13-22 in postanal ventral series (from 2nd to 14th-17th postanal myomere); later in stage, several ventrally on gut, on pectoral fin blade (concentrated at margin)). Flexion: on nape, forebrain, snout near upper jaw, and on pelvic fins; on pectoral fins spreading from margin of blade toward base. Postflexion: on upper opercular region and posteriorly on upper head; on dorsum along first dorsal and second dorsal fins; late in stage, saddles begin to extend ventrad from dorsum, on first dorsal and second dorsal and anal fin membranes. Pelagic juvenile: saddle at dorsal fin origin; 2 bars below first dorsal fin, 1 below second dorsal fin, and 1 at caudal peduncle. Sequence of fin development: pectorals, caudal, dorsal and anal and pelvics. Also Ref. 34817.
