Myomeres 16-18 (usually 16-17) + 15-18 (usually 16-17) = 32-35 (usually 33-34); dorsal and anal fin rays 5-8; pectoral fin rays 17-19 (usually 18: full complement present in postflexion stage); eyes more or less round in larval stage; larvae with lateral pigment, usually in single row along lateral midline from about myomere 3-5 through 10-12, usually expanding to 2 or 3 rows to about postanal myomere 3-5; no pigment on dorsal or ventral margins. Pigmentation: Yolk-sac through postflexion: 7-22 laterally in 1-3 longitudinal rows between myomeres 3-5 and 19-20, usually about 11-16 to flexion stage, decreasing to 8-10, mainly along lateral midline, by postflexion stage; series (widely spaced) internally under hindbrain and over gas bladder and gut to end of hindgut, becoming more or less continuous pigment by about 3.5 mm; 1 (large) laterally under pectoral fin base in preflexion stage, disappears during flexion stage; dorsal and ventral margins unpigmented. Juvenile: no melanistic pigment. Sequence of fin development: caudal, pectorals, dorsal and anal, pelvics. |
