| Larvae slender; gut straight, extending to midpoint of body in early larvae (3.8 mm) and beyond midpoint (60% of BL) in larger larvae; eyes round in all the larval stages. Pigmentation: present over gas bladder; internal pigment on anterior part of the gut ( in front of liver) barely visible in largest larvae but distinct in larvae <7.5 mm, and generally more apparent in preflexion larvae; postanal pigmentation consists of a series of midventral tail melanophores (about 18-20) in preflexion stages that disappear gradually during flexion and fuse to form one or two large melanophores posterior to anal fin; dorsal pigmentation on tail appears in preflexion stages at about 5 mm and consists of a double line of pigment extending along 5 or 6 myomeres; in postflexion stages dorsal pigmentation consists of several melanophores located from dorsal fin insertion to caudal peduncle; pigmentation above brain distinct in largest larvae (12.4 mm), but indistinct or absent in earlier stages; pigmentation absent in otic region. Sequence of fin development: caudal; anal; dorsal; pectoral; pelvic. Sequence of photophore development: Br2 (6 mm BL); PLO (10 mm); PO5 (12.5 mm). Gill raker count: 3 or 4 +1+6 (12.4 mm). | ||||
