Diagnostic characters: cross-hatched pattern of muscle fibers visible until 15 mm; anus migrates anteriorly from myomere 35 to 30 between 2.5 and 19.1 mm; posterior end of dorsal fin 3-6 myomeres in front of origin of anal fin; melanophores over gut in postflexion larvae restricted to posteriormost portion of hindgut.
Sequence of fin development: caudal (5.3-10.0 mm); dorsal (5.4-10.4 mm); anal (7.2-11.8 mm); pelvic (10.4-15.6 mm); pectoral (15.6->18.1 mm).
Minute teeth in both jaws by mid-flexion stage (Ref. 33617). Gut very long, straight and with striated hindgut (Ref. 33617). Gas bladder inflated only in larvae caught at night (Ref. 33617).
Larvae have been caught in Lake Macquarie from September to April, with peak abundances between January and March (Ref. 33621). |
