| Newly hatched larvae remained suspended in the water column in an inclined position with the ventral side oriented towards the surface. When in motion, it jerked, corrected its position, darted rapidly upward then sank to its resting position.
Unpigmented eyes, scattered melanophores, and absence of fin buds or mouth parts.
The larva has five or six pairs of cupulae on the body side from eye to tail, and several pairs on the front of the head (Ref. 79496). |

| At the early larval stages the urostyle region is sometimes pigmented.
At 4.0 mm, 7 caudal rays present; dorsal rays evident.
At 6.7 mm, spines of 1st dorsal and rays of 2nd dorsal can be easily counted.
At 5.4 mm, full complement of principal caudal rays and anal rays present.
At 9.7 mm, secondary caudal rays present.
At 35-45 mm SL, formation of 3rd anal spine and recognized as end of larval period.
The lower jaw region is characterised by an acute angle of the dentary symphysis and lightly pigmented ventro-opercular and gular regions of the head (Ref. 74869). Feeding begins three to five days after hatching (Ref. 79496). |
