Short description

Dorsal spines (total): 10; Dorsal soft rays (total): 9; Anal spines: 3; Anal soft rays: 8. The snout is moderately long, its dorsal profile slightly concave. Body color is bluish gray or brown often with scattered irregular dark blotches on sides; sometimes three dark streaks radiate forward from the eye. The fins are pale or orangish.

Found over sandy areas near coral reefs (Ref. 30573). Feeds on fish, crustaceans, cephalopods, and polychaetes. Swims in small schools sometimes together with L. olivaceous. Utilized as a food fish.
