Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 9; Raggi dorsali molli (totale) : 12; Spine anali: 3; Raggi anali molli: 12. Two-color forms: the 'true' species in the Indian Ocean and Red Sea and its sibling in the Pacific regions. Females look almost black; males mainly greenish with blue face, of which Indian form shows a white band central to the body, whilst the Pacific form a pale peduncular area when in nuptial mode (Ref. 48636). Juvenile H. annulatus very closely resemble juvenile Malacanthus latovittatus (Ref.1602). Poorly developed pharyngeal teeth (Ref. 1602).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Found on coral reefs and rocky substrates to depths of at least 30 m (Ref. 9823) on offshore reef slopes (Ref. 90102). Juveniles generally solitary (Ref. 9710). Feeds primarily on small fishes, also on crustaceans (Ref. 2334).
