Etymology: Cephalopholis: Greek, kephale = head + Greek, pholis = scale (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 1 - 60 m (Ref. 5222), usually 3 - 15 m (Ref. 9710). Tropical; 34°N - 30°S, 33°E - 131°W (Ref. 5222)
Pacific Ocean: eastward to French Polynesia and the Pitcairn Islands, and to Christmas Isalnd in the Indian Ocean
17Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 17 - ? cm
Max length : 28.0 cm TL male/unsexed; (Ref. 5222)
soft rays: 8 - 9. Distinguished by the following characteristics: fin with a pair of diagonal white bands; body scales ctenoid; greatest depth of body 2.7-3.1 in SL; rounded caudal fin; pelvic fins 1.8-2.2 in head length (Ref. 90102); head length 2.4-2.7 in SL; convex interorbital area; rounded preopercle, finely serrate, fleshy lower edge; subopercle and interopercle usually smooth; maxilla reaching well past eye; pectoral fins distinctly longer than pelvic fins; caudal fin rounded; snout and maxilla with minute cycloid scales (Ref. 089707).
Inhabits clear, shallow waters of outer reef areas. Also found in lagoons, back-reef areas, and on the reef-top. Prefers healthy coral reef in shallow area therefore is greatly affected by reef degredation (Ref. 089707). Feeds on small fishes (68%) and crustaceans. Solitary (Ref 90102).
