Myoseptal pigment above gut; pigment over notochord and 6-7 predorsal melanophores; 8-9 (usually 9) ceratobranchial gill rakers, present by at least 11.5 mm, probably sooner. Pigmentation: Postflexion: at cleithral symphysis; pair long along sides of gut anteriorly; over gas bladder; 1 over end of hindgut; 10 on myosepta above gut anteriorly; 11 internal, ventrally along tail; external on anal fin ray bases; on parhypural; at center of hypural margin; over notochord, extending anteriorly to 6 melanophores past dorsal fin origin. Transformation: scaterred over dorsal surface of head and upper half of body by 14 mm; along margins of branchiostegal membranes by about 11.5 mm, covering membranes by 14 mm. |
