生態学
海 関連する礁; 深さの範囲 9 - 150 m (Ref. 9710). Tropical; 31°N - 30°S, 30°E - 77°E (Ref. 55)
Western Indian Ocean: Red Sea east to the Arabian Sea and south to Natal, South Africa. Records of this species from the eastern Indian Ocean and the Western Central Pacific are probably misidentifications of Lutjanus malabaricus (Ref. 55). Has been misidentified as Lutjanus coccineus by recent authors.
Length at first maturity / サイズ / 重さ / 年齢
Maturity: Lm 51.1, range 50 - 60 cm
Max length : 100.0 cm TL オス/雌雄の選別がない; (Ref. 9710); common length : 70.0 cm TL オス/雌雄の選別がない; (Ref. 5450); 最大公表体重: 23.0 kg (Ref. 469); 最大記録サイズ: 13 年 (Ref. 1488)
背面の脊椎 (合計) : 10; 背鰭 (合計) : 13 - 14; 肛門の骨: 3; 臀鰭: 8 - 9. Dorsal profile of head angular, snout steeply sloped. Preorbital bone broad, with horizontal grooves behind and below the eye. Anterior and posterior nostrils widely spaced. Preopercular notch and knob poorly developed. Scale rows on back rising obliquely above lateral line. Juveniles with a broad brown bar from upper jaw to beginning of dorsal fin and a series of reddish horizontal lines on sides.
Adults inhabit coral and rocky reefs to depths of at least 100 m (Ref. 30573). Off South Africa they display a preference for slightly silty, turbid regions in the vicinity of sometimes shallow, offshore banks. Captured mainly at night on coral banks off Mafia Island (Tanzania) in 9 to 12 m and off Zanzibar in about 75 m. They are active at night feeding over sandy or rubble bottoms (Ref. 9710). Maximum depth reported taken from Ref. 9773.
