Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 9; Dorsal soft rays (total): 11; Anal spines: 0; Anal soft rays: 11. Prominent pit present behind upper eye. Preopercular spines short, upper two subequal. Infraorbital ridge usually smooth over eye. Suborbital ridge bearing 1 spine below rear of eye. Dorsal fin IX or I,VIII. Dermal papillae (usually 6-9 in adults) on upper surface of eye, longest branched and reaching well above supraorbital ridge. Short dark streaks usually crossing rays in dorsal and caudal fins.

Biology     Glossary (e.g. epibenthic)

Inhabits shallow rocky coastal areas frequently associated with seaweed beds and mangroves, most commonly at depths of less than 5 m (Ref. 9790). Also found on sand bottoms (Ref. 3132).
