Transverse rugae lining gut only in posterior section, anteriorly an elongate s-shaped fold is present along with longitudinal rugae; gut fold unpigmented; paired melanophore series between trunk and gut; hypural pigment; dorsal and pelvic fin origins slightly posterior to midbody; rays form early in pectoral fin; guanine layer developing in late postflexion stage; fin rays form in finfold, away from body margin. Pigmentation: embedded pigment above gut; superficial head pigment (>8.4 mm SL); with development, embedded line of melanophores running length of body; conspicuous caudal pigment; ventral pigment from isthmus along anterior 2/3 of gut Sequence of fin development: pectorals, caudal, dorsal and anal, pelvics. |
