Pectoral fin with elongate lower portion; trailing gut after about 5-6 mm; pigmented along lower part of myosepta, on pectoral fin and ventrum between pectoral fins, on branchiostegal membrane, stripes on snout. Pigmentation: Preflexion-postflexion: ventrolateral series along myosepta, increases with larval size, extends onto caudal finfold by about 6 mm; increases on pectoral fin base and ventrum between bases, spreads onto isthmus by 6 mm; patch on branchiostegal membrane by 4.9 mm; pair of longitudinal bands on snout; along mandibular symphysis extending along sides of lower jaw by 8 mm; on trailing part of gut. Sequence of fin development: caudal, dorsal, anal, pelvics, pectorals. |
