Ecologia
marino associati a barriera corallina; distribuzione batimetrica ? - 20 m (Ref. 9710). Subtropical; 10°S - 37°S, 143°E - 170°E (Ref. 55)
Western Pacific: restricted to the east coast of Australia and New Caledonia. The main Australian distribution is off southern Queensland between Cape Moreton (about 27°S) and the Capricorn Group(23°S). This species has been usually referred to as Lutjanus amabilis by previous authors.
Length at first maturity / Size / Peso / Age
Maturity: Lm 25.0, range 20 - 30 cm
Max length : 50.0 cm TL maschio/sesso non determinato; (Ref. 55); common length : 30.0 cm TL maschio/sesso non determinato; (Ref. 55); Età massima riportata: 40 anni (Ref. 2290)
Spine dorsali (totale) : 10; Raggi dorsali molli (totale) : 14; Spine anali: 3; Raggi anali molli: 8. Snout somewhat pointed. Preopercular notch and knob moderately well developed. Scale rows on back rising obliquely above lateral line. Generally pale blue-gray to whitish with suffusion of yellow on upper back. A prominent golden brown stripe, slightly narrower than the eye, runs laterally from the rear edge of the of the opercle to the caudal peduncle.
Adults mainly inhabit coral reefs. Sometimes forming large aggregations around rocky outcrops during daylight hours. They disperse to feed at night (Ref. 9710). Usually marketed fresh.
