By late preflexion stage, pigment row present along ventral tail margin and heavy patch anterior to anus; total caudal fin rays 27-32; pelvic fin rays 7; morphology similar to P. nematopus; voluminous fins. Pigmentation: Preflexion: on brain, nape, gut, jaw angle, and operculum; along cleithrum; in finfold near end of tail; by 5 mm, heavy anterior to anus, on isthmus, and internal rows dorsal and ventral to notochord at midtail. Flexion: line along ventral tail margin extending almost to trunk; row along dorsal tail margin, reduced near end of tail. Preflexion: on base of pelvic fin and pectoral fin, on pectoral fin rays, and on dorsum in anterior tail region. Juvenile: on fins, peritoneum, branchiostegal region, and scattered all over the body. Sequence of fin development: pelvics, pectorals, second dorsal and anal, first dorsal and caudal. |
