8-11 vertebrae anterior to vexillum origin; 9-11 anal fin rays to dorsal fin origin; 39-42 dorsal fin rays anterior to 31st vertebra; prevexillum length > about 1.6 HL; vexillum just anterior to first dorsal fin ray; preanal fin formation larvae have pigment on tip of lower jaw, on gular region, and internally on snout; anal fin formation larvae have pigment ventrally on gut and dorsoposteriorly on peritoneum later in stage. Transformation length: vexillifer stage to about 130 mm TL; smallest adults about 85 mm TL. Pigmentation: Preanal fin formation: on gular region; over brain and gas bladder; internally anterior and posterior to vexillum to about 66% of tail; primarily midlaterally in posterior about 33% of tail; by about 8 mm TL, only laterally on tail; by about 10.5 mm, only near end of tail. Anal fin formation: at about 14 mm, over cranium and internal ventrally on brain; by 40 mm, dorsoposteriorly on peritoneum. Sequence of fin development: dorsal and anal, pectorals and caudal. |
