| High dorsal fin ray count (21-24); initially slender, with short, strongly sigmoid gut; head and body become deep and compressed; snout acute in preflexion stage, becoming bulbous; eyes large, nearly round; teeth well developed; anteriorly hooked teeth on posterior part of lower jaw; complex pigment pattern; Br2 photophores form at 4.2 mm; PO5 at 6.2 mm; Vn at 9.2 mm; PLO at 16.2 mm. Pigmentation: Preflexion: jaw tips, above brain and swimbladder, lateral cleithral. Flexion: transverse pair above midbrain in some larvae and beginning of series on hypaxial region above anal fin base in some larvae. Postflexion: lower jaw, hindbrain, nape, double row of melanophores along dorsal midline beginning at midbody, series along anal fin base, caudal fin base, pelvic and anal fin, internal notochord pigment on trunk. Sequence of fin development: caudal, dorsal and anal, pectorals and pelvics. | ||||
