البيئة
بحري مرتبطة بالشعاب; نطاق العمق 5 - 100 m (Ref. 55). Tropical; 34°N - 35°S, 47°E - 180°E (Ref. 55)
Indo-West Pacific: Persian Gulf and Gulf of Oman to Fiji, north to southern Japan and Jeju Island, Korea (Ref. 114833), south to New South Wales, Australia (Ref. 114833) and New Caledonia (Ref. 86942). This species has been referred to as Lutjanus malabaricus (non Schneider) or Lutjanus altifrontalis by many recent authors. Occurrence in the Red Sea is a misidentification (Ref. 84159).
Length at first maturity / الحجم / وزن / العمر
Maturity: Lm 50.2, range 50 - ? cm
Max length : 81.6 cm FL ذكر/ مختلط الجنس; (Ref. 5739); common length : 45.0 cm TL ذكر/ مختلط الجنس; (Ref. 55); العمر: 8 سنين (Ref. 5739)
الأشواك الظهرية (المجموع) : 11; الأشعة الظهرية الناعمة (المجموع) : 12 - 14; شوكة شرجية: 3; أشعه شرجية لينه: 8 - 9. Deep-bodied. Dorsal profile of head sloped. Length of upper jaw smaller than distance bet. base of last dorsal and anal rays. Preorbital bone usually narrower than eye diameter. Preopercular notch and knob poorly developed. Scale rows on back rising obliquely above lateral line. Juveniles with an oblique band extending from mouth to beginning of dorsal fin and a black spot at the caudal peduncle (Ref. 469). Body depth 2.5-3.0 in SL (Ref. 90102).
Adults inhabit trawling grounds and reefs. They are present over shoals, rubble, corals, large epibenthos, hard or sandy mud substrates and offshore reefs (Ref. 6390). Usually in groups (Ref. 90102). Juveniles from about 2.5 cm length inhabit shallow waters over muddy substrates (Ref. 6390). Feed on a broad range of prey dominated by fish, and with small amounts of crustaceans, cephalopods and other benthic invertebrates (Ref. 6390). They forage mostly at night (Ref. 6390). They are marketed either gilled and gutted, whole as fillets, as fresh chilled or frozen product (Ref. 6390).
Are serial batch spawners (Ref. 6390).
