(total): 8. A series of three large blackish blotches on upper side of body beneath dorsal fins; color variable but usually pale, the scales of the back with reddish or yellowish brown edges and a central pale blue spot; diagonal light blue lines on head. Capable of displaying a pattern of large red blotches on head and body in less than a minute (Ref. 13442).
Inhabits shallow waters to depths of 90 m (Ref. 9626), especially over sand and rock bottoms in reef areas. Young juveniles often found on beds of seagrass, e.g. Thalassia. Feeds on small invertebrates (Ref. 9626). Flesh highly esteemed; marketed fresh and frozen (Ref. 3792). Traded as an aquarium fish at Ceará, Brazil (Ref. 49392).
