Moderately slender; gut moderate in length, slightly sigmoid; eye slightly elliptical with lunate ventral choroid tissue; lateral midline and ventral finfold pigmentation; photophores form at transformation; caudal luminous glands form in late larvae. Pigmentation: Preflexion: at 3.0-4.5 mm, up to 11 dashes on lateral midline, 1 embedded at pectoral fin base, about 7 embedded ventral median postanal dashes, on margin of ventral finfold, and pair on terminal gut section and laterally on midgut; at 4.5-5.5 mm, 1 in midline at cleithral symphysis, 1 at lower symphysis, midlateral series reduced to 2-6, and postanal series reduced to 2-4. Flexion: pair at midlateral gut; delicate series along bases of anal fin rays; one at anal fin insertion and 1 or 2 on ventral margin of caudal peduncle. Postflexion: vertical series at base of caudal fin rays; by 10 mm, 1 or 2 above caudal peduncle and at adipose fin base. Sequence of fin development: caudal, anal, dorsal, pectorals, pelvics. |
