| Large melanophore on peritoneum anterior to liver; melanophore(s) at anterior margin of forebrain after 6-7 mm; relatively short, compact gut; up to 8 small to moderate spines on posterior preopercular margin; myomeres 7-9+16-19=25-27 (usually 8+18) through flexion stage, 9-12+14-17 (usually 10+16) in postflexion stage.
Pigmentation:
Preflexion-postflexion: None externally on head except at angular before about 8-9 mm, then forming and increasing on dorsum and jaws; on gular and opercular areas beginning at about 12.0 mm; present or absent under hindbrain after about 3.3 mm; at anterior margin of forebrain after about 6-7 mm; 1-7 on ventral margin between isthmus and anus; on dorsal surface of gas bladder and gut; usually 1 anteriorly at liver; externally, laterally on abdominal area after about 8.0 mm; 10-23 (usually 13-17) on ventral margin of tail; on anal fin base after about 4.4 mm; anteriorly on dorsal margin after 12.0 mm; 0-few on hypural margin and caudal fin rays.
Transformation: Dorsolateral and midlateral stripes; increasing on upper half of body; on first dorsal and caudal fin rays.
Sequence of fin development: principal caudal fin rays, second dorsal and anal, procurrent caudal fin rays, pectoral, first dorsal, pelvic. |
