Heavy pigment on top of head, on jaws, in a ventral postanal series, and on paired fins; pigment on pectoral fin base and on blade, heaviest at distal margin; large, serrated parietal spines; larvae of other Sebastomus species share these features. Pigmentation: Preflexion: initially, dorsolaterally on gut, 11-17 in postanal ventral midline series (from 3rd to 15th postanal myomere), at lower jaw tip, ventral midline series below gut, and pectoral fin blade covered (darkest at distal margin). Flexion: at 7.1 mm, on snout, above brain, on nape, 1 at hypural margin, solid on pectoral fin base, on pelvics, on isthmus, and 11 in embedded series on postanal ventral midline. Sequence of fin development: caudal, pectorals, dorsal and anal and pelvics. Also Ref. 34817. |
