Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 49.0 cm TL male/unsexed; (Ref. 9710)
soft rays: 9. Scales large. 4 medial predorsal scales; 2 scale rows on cheek. Caudal fin truncate in both phases. Lips do not cover dental plates. Adults with 1-2 canines posteriorly on side of upper dental plate. The initial phase is reddish-brown with a diffuse yellowish patch in the center of the caudal peduncle and markings on the lips similar to those of the terminal male (Ref. 1602). Males identified by white patch on cheek and females strongly barred (Ref. 48636).
Indo-Pacific: East Indian region to Micronesia, Samoa, and Fiji and Philippines to Australia; throughout East Indian region except Andaman Sea.
Found in clear coastal and inner reefs (Ref. 48636); in lagoons and channel reefs (Ref. 2334). Feed mainly on algae (Ref. 26993). Females usually in small groups and maybe mixed with other species when feeding; males solitary nearby (Ref. 48636).
