| Diagnosis: | In preflexion larvae, head pigment absent, 1 peritoneal pigment patch; in flexion-postflexion larvae, 1-9 peritoneal pigment patches, decreasing in size posteriad; pelvic fin posterior to a vertical through dorsal fin origin in transformation and juvenile specimens. Pigmentation: Preflexion: 1 peritoneal patch. Flexion: 1-4 peritoneal patches, decreasing posteriad. Postflexion: on tip of snout; lower jaw; infraorbital region; cranium; above and below notochord from posterior part of anal fin through caudal peduncle; 4-9 peritoneal patches; by about 25 mm, on base of dorsal fin and bases of first few anal fin rays. Transformation: on dorsum from dorsal fin to caudal fin. Sequence of fin development: caudal, anal, dorsal, pectorals, pelvics, adipose.. See also LARVAE table. | |||
