Épines dorsales (Total) : 12; Rayons mous dorsaux (Total) : 12; Épines anales: 3; Rayons mous anaux: 10. Dorsal profile of head moderately steep; prefrontal tubercle not well developed; silvery with a lavender iridescence, the edges of the scales brownish yellow and the centers with a vertically elongate iridescent blue-green or blue spot (Ref. 13442).
Adults often seen over rocky areas or reefs, but also on flat bottoms to about 85 m depth, while the young inhabit shallower waters (Ref. 3815).
