Transparent, with yellow eyes and a small yolk sac (Ref. 27547). Swims actively toward the light (Ref. 27547). Pigmentation: cluster on posterior surface of yolk sac; 9 on ventral midline below gut, some entering finfold; 4 on postanal ventral midline; 1 below notochord tip; lateral pair below pectoral fin base. |

Number and arrangement of preanal ventral midline melanophores (lacking in clupeoid larvae); absence of diagonal muscle layers that are present in clupeoids. Pigmentation: Preflexion-flexion: 8-11 on preanal ventral midline; 2-4 on postanal ventral midline; 1-4 below notochord tip; about one-third of larvae have 1-2 on postanal dorsal midline; lateral pairs between gut and trunk musculature increasing to 15-16 at end of flexion stage; lateral pair on terminal section of gut. Sequence of fin development: caudal, anal and dorsal, pectoral and pelvics. |
