Peritoneal pigment present midway to anteriorly over gut by 6 mm, dorsolateral pair added posteriorly by 8.4 mm; laterally on caudal peduncle after 15-16 mm. Pigmentation: Preflexion-flexion: single peritoneal patch above mid-gut by about 6 mm, usually shifts slightly cephalad by about 10 mm; pair of dorsolateral peritoneal patches posteriorly by 8.4 mm. Postflexion: few externally over hypural area by 15-16 mm, spreading cephalad as dorsolateral and ventrolateral stripes adjacent to lateral midline beginning at about 25 mm; internally on hindbrain by 28 mm. Transformation: externally over midbrain by 33 mm, spreading over forebrain by about 42 mm; on snout, upper jaw, and gular membrane; on dorsal fin by 42 mm; peritoneal sections fuse. Sequence of fin development: caudal, pectorals, anal, dorsal, pelvics. |
