Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 8 - 9; Spine anali: 0; Raggi anali molli: 9. Caudal fin rays 10. Juveniles bright yellow with black spots; the spots decrease proportionately and the bright yellow becomes a dirty mustard with growth; large adults become bluish with yellowish seams between the plates.
Body shape (shape guide): short and / or deep.
Inhabit lagoon and semi-sheltered seaward reefs. Juveniles often among Acropora corals (Ref. 9710). Benthopelagic (Ref. 58302). Solitary (Ref. 5503). Juveniles expatriating to subtropical zone from the pelagic larval stage. Small juveniles secretive in narrow crevices (Ref. 48637). Feed primarily on algae with a compliment of microorganisms, invertebrates, mollusks, sponges (Ref. 5503), sand dwelling polychaetes, crustaceans, foraminiferans, and fishes (Ref. 37816).
