Slender gut with Sn-A/BL about 55-60% through postflexion stage; gas bladder far posterior (about myomeres 10-12); pigment only over gas bladder before transformation. Pigmentation: Preflexion-flexion: none. Postflexion: none initially, over gas bladder by about 8.5-9.0 mm. Transformation: initially over gas bladder only; on stomach by about 12.0 mm; increases over gut region; little over midbrain, few in dorsolateral series along trunk; beginning to form near end of stage. Sequence of fin development: caudal, anal, pectorals, dorsal and pelvics. |
