| High total vertebral count (39-41); slender body; gut relatively long, slender and straight; head relatively small; eyes round; distinct pigmentation, particularly in caudal peduncle region and embedded above spinal column. Pigmentation: Preflexion: by 4.9 mm, elongate apposing median blotches in future caudal peduncle region, 1 above terminal gut section, 1 above gas bladder, 1 at nape, 1 embedded in otic region, 1 midline above cerebellum and 1 above medulla; by 6.8 mm, embedded series extends full length of spinal column. Postflexion: by about 10.0 mm, beginning of paired series on each side of dorsal fin, median spot at anal fin insertion, and series on hypural margin; in late postflexion stage, paired series extends from dorsal fin origin to caudal fin and paired ventral series at anal fin and posterior caudal peduncle. Sequence of fin formation: caudal, dorsal and anal, pectorals, pelvics. | ||||
