Taxonomic Remarks
Common names may have to be split accordingly to former synonym japonicus and new species insularis), following distribution (Ref. 123820).

生態学
海 関連する礁; 移住性ではない; 深さの範囲 4 - 300 m (Ref. 11888). Tropical; 37°N - 34°S, 28°E - 169°W (Ref. 5222)
Western Indian Ocean: restricted.
初回成熟時の長さ / サイズ / 重さ / 年齢
成熟: Lm 27.0, range 23 - 31 cm
Max length : 80.0 cm TL オス/雌雄の選別がない; (Ref. 89707); common length : 50.0 cm TL オス/雌雄の選別がない; (Ref. 5450); 最大公表体重: 7.0 kg (Ref. 4787); 最大記録サイズ: 29 年 (Ref. 42001)
背面の脊椎 (合計) : 11; 背鰭 (合計) : 16 - 18; 肛門の骨: 3; 臀鰭: 8. Live color whitish, with small dark brown spots on head, body, and fins except ventrally on head, thorax, and lower abdomen. Can assume a transient color phase of 3-4 rows of very large round dark spots on top of the small-spot pattern. 96-125 scales in longitudinal series. Pyloric caeca 26-52 (Ref. 04787); characterized further by having ctenoid body scales, except cycloid scales on nape, thorax, parts of ventral abdomen; body with auxiliary scales; greatest depth of body 2.8-3.3 in SL; truncate to slightly emarginate caudal fin; pelvic fins 1.7-2.4 in head length (Ref. 90102); interorbital slightly convex; preopercle angle rounded, 4-7 enlarged serrae at angle below a slight notch; upper edge of operculum straight; posterior nostril not noticeably larger than anterior nostril; maxilla reaches about to vertical at rear edge of eye; scaly maxilla, low step on posterior part of ventral edge; 2-4 rows of teeth in midlateral part of lower jaw, inner ones about twice the size of outer teeth (Ref. 089707).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Found over a wide range of habitats like seagrass beds and outer reef slopes (Ref. 5213), also on mud bottoms. Solitary (Ref. 90102). Feed on small fishes and crustaceans (mainly stomatopods and crabs). Sexual transition from female to male occurs between 35-45 cm, but not all females change sex. Mature individuals form spawning aggregations (Ref. 55367). E. chlorostigma is closely related and very similar to E. polylepis and E. gabriellae which seem to replace it in the northwestern Indian Ocean. Solitary (Ref. 90102).
