Small, deep-bodied, with large head; skin inflated and somewhat balloon-like; 5-6 preanal myomeres (through flexion stage), 18-20 total myomeres; "scutatus" stage develops between 3.4-3.6 mm; diagnostic fin ray counts present by 3.3 mm. Pigmentation: Preflexion-postflexion: on nape, becoming internal during flexion stage, extending posteriorly over notochord; under mid- and hindbrain; dorsally and dorsolaterally on gut; ventrally on gut beginning posteriorly, spreading anteriorly during flexion; inside gill cover at level of eye beginning in flexion stage. Juvenile: completely pigmented, with scattered darker spots; bands on dorsal, anal, caudal, pectoral fins. Sequence of fin development: caudal, dorsal and anal and pectorals and pelvics. |
