Environment: milieu / climate zone / depth range / distribution range
Ecologia
marino associati a barriera corallina; non migratori; distribuzione batimetrica 1 - 30 m (Ref. 89707), usually 1 - 15 m (Ref. 90102). Tropical; 36°N - 34°S, 30°E - 143°E (Ref. 5222)
Indo-West Pacific: western India to Philippines, north to southern Japan (Honshu), south to northern Australia. 'Epinephelus formosus' from Madagascar (Ref. 6457), Réunion and Mauritius (Ref. 6458) are probably based on misidentifications of Cephalopholis polleni. Confused with Cephalopholis boenak.
Length at first maturity / Size / Peso / Age
Maturity: Lm 17.0 range ? - ? cm
Max length : 34.0 cm TL maschio/sesso non determinato; (Ref. 4787)
Spine dorsali (totale) : 9; Raggi dorsali molli (totale) : 15 - 17; Spine anali: 3; Raggi anali molli: 7 - 8. Characterized by: dark brown to yellowish brown color with narrow blue stripes; body with ctenoid scales, including abdomen; greatest depth of body 2.5-2.9 in SL; rounded caudal fin; pelvic fins, 1.6-2.0 in head length (Ref. 90102): head length 2.4-2.6 in SL; preorbital depth 3.6-4.3% SL, more than half maxilla width; convex interorbital area; rounded preopercle, finely serrate, lower edge fleshy; smooth subopercle and interopercle; maxilla naked, reaching to or just past vertical at rear edge of eye (Ref. 089707).
Like C. boenak, it prefers shallow dead or silty reefs and this may account for the primarily continental distributions of these two species. Solitary (Ref 90102).
