Aliform pectoral base; head large, flattened; slightly stalked eyes in preflexion to early postflexion stages; narrow elliptical eyes in preflexion stage, becoming oval in postflexion stage; conical ventral choroid tissue; pigment sparse; Br2 photophores form from 6.5-7.0 mm. Pigmentation: Preflexion: by 3.0 mm, up to 2 postanal ventral margin, pair on terminal section of gut, 0-2 pairs along gut (sometimes missing on one side), and pair at cleithral symphysis; by 5.0 mm, pair at lower jaw symphysis and some have pair on isthmus. Flexion-postflexion: series basally on pectoral fin rays; lacking on postanal and gut regions. Sequence of fin development: pectorals, caudal, anal, dorsal, pelvics. |
