Spine dorsali (totale): 12; Raggi dorsali molli (totale): 12; Spine anali 3; Raggi anali molli: 10. Blue line under each eye. Corner of mouth and isthmus have orange cast (Ref. 26938). An irregular row of small molariform teeth inside and toward the front of the three usual rows of molars at side of upper jaw; dorsal profile of head evenly convex and not very steep (Ref. 13442).

Biologia     Glossario (es. epibenthic)

Inhabits coastal waters. Found on vegetated sand bottoms and more frequently on coral bottoms. Occasionally found at depths at least 180m (Ref. 09710) and 200 m. (Ref. 26938). Large adults are usually solitary. Feeds mainly on sea urchins, (including Diadema, Ref. 13442), crabs and mollusks. Excellent food fish (Ref. 5521).
