Short description

Dorsal spines (total): 9; Dorsal soft rays (total): 27-30; Anal spines: 3; Anal soft rays: 25 - 28. Upper 3/4 of body with alternating black-edged blue and yellow bands; lower 1/4 of body gray. Erectile spine on each side of caudal peduncle is sharp, strong, forward-pointing, and venomous. Upper part of head with yellow, oblique stripes. Pectoral fins pale with dusky rays; pelvic fins light yellowish brown with black outer margin; vertical markings in caudal fin. Gill rakers 14-16 anterior row, 13-15 posterior row. Minute scales. Philippine specimens demonstrate different color patterns.

A territorial species (Ref. 167) which is common in surge zones of exposed seaward reefs. The large male controls well-defined feeding territories and harems of females (Ref. 1602, 48637). Benthopelagic (Ref. 58302). Adult usually forms schools and commonly found in shallow gutters. Juvenile solitary and secretive on shallow rubble habitats (Ref. 48637). The species is almost continually in motion. Herbivorous but also feeds on crustaceans (Ref. 5503). The venomous caudal spine can cause painful wounds. Forms spawning aggregations (Ref. 27825).

IUCN Red List Status (Ref. 115185)

Least Concern (LC)
