Pigmentation:
Preanal fin formation: over top of head; on snout and lower jaw; internally over peritoneum; along bases of dorsal and anal finfolds; absent laterally on the posterior one-third of tail.
Anal-fin formation through transformation: increasing laterally on body and tail; lateral posterior one-third of tail remains lightly pigmented.
Sequence of fin development: pelvics, first dorsal, anal, second dorsal, pectorals. |
