| Branchiostegal rays 6; total first dorsal fin 10-12; pelvic fin 9-10; gas glands 6; basipterygia extremely robust from anal fin formation through transformation stages; relatively wide space between insertion of first dorsal fin and origin of second dorsal fin; pigmentation heavy over trunk in evenly spaced spots not extending posterior to tenth anal fin ray by juvenile. Pigmentation: Preanal fin formation: above, below, and posterior to eye; heavy on trunk; scattered dorsally from midbrain posteriorly to about myomere 7; absent from pectoral fin base. Anal fin formation: on frontal region of head, increasing below and posterior to eye; extending over trunk posteriorly to about the fifth dorsal fin ray. Transformation-juvenile: evenly scattered spots on trunk from just anterior to first dorsal fin posterior to about the tenth anal fin ray. Sequence of fin development: pelvics, first dorsal, anal, second dorsal, pectorals. | ||||
