Adults: Pale yellow-green-blue dorsally, becoming silver on the underside, often with a yellow cast. Tail yellow. One of the major identification features is that the upper jaw does not extend to the inferior margin of the eye.
Juvenile: With a dark, almost vertical, bar through eye to mouth.
A reef-associated species occurring over continental shelves and slopes in depths between 5-70 m. It usually occurs as a solitary species or in small groups, often around outer reefs (it is not common inshore). Adults feed primarily on bottom-dwelling fishes.
It reaches sexual maturity at 30 cm fork length (FL) in males and 32 cm FL in females. It exhibits group spawning behaviour closely resembling that of Permit. Schooling densely at ~40-45 m and subgroups of 5 to 8 fish then detach themselves from the school to spawn.
