Diagnostic characters: anus migrates anteriorly from myomere 40 to 36 between 4.0 and 16.8 mm; posterior end of dorsal fin 5-8 myomeres in front of origin of anal fin; 5-8 internal melanophores dorsally along hindgut. Sequence of fin development: dorsal (6.7-16.0 mm); caudal (7.6-13.0 mm); anal (10.0-16.0 mm); pelvic (14.0->16.8 mm); pectoral (>16.8 mm). Larvae have been caught in the upper Swan Estuary in December and January (Ref. 33820). Gas bladder inflated in postflexion larvae caught at night (Ref. 33617). Yolk sac is resorbed by 4.2 mm NL (Ref. 33617). Scales form after 30 mm SL (Ref. 33830). |
