Etymology: Lethrinus: Greek, lethrinia, a fish pertaining to genus Pagellus. More on author: Valenciennes.
Environment: milieu / climate zone / depth range / distribution range
; 海 関連する礁; 移住性ではない; 深さの範囲 ? - 40 m (Ref. 9710). Tropical; 30°N - 30°S, 33°E - 93°E
Indian Ocean: including the Red Sea and the Persian Gulf south to Durban, South Africa, then east to North Bay Reef, Andaman and Nicobar Islands. Reports of this species elsewhere are probably due to misidentification.
Length at first maturity / サイズ / 重さ / 年齢
Maturity: Lm 21.3  range ? - ? cm
Max length : 40.0 cm TL オス/雌雄の選別がない; (Ref. 2295); common length : 25.0 cm TL オス/雌雄の選別がない; (Ref. 2295)
背面の脊椎 (合計): 10; 背鰭 (合計): 9; 肛門の骨 3; 臀鰭: 8. The inner surface of the pectoral fin base is densely scaled; posterior angle of the operculum is fully scaled; cheeks without scales. Color of body is dark gray or yellow-brown, head is brown-gray. The centers of scales are lighter. Sometimes there is an irregular pattern of broken dusky bars becoming whitish on the lower part of the body. The pectoral and pelvic fins are white of pinkish. The dorsal and anal fins are mottled white or yellowish with reddish edge. The caudal fin has indistinct reddish bands.
Found in sandy areas near reefs during daytime, sometimes in small groups. At night, they are solitary and range over reef-flats and slopes where they feed primarily on echinoderms, mollusks and crustaceans (Ref. 2295). The taxonomy of this species has been considerably confused.
