Maturity: Lm ? range ? - 50 cm
Max length : 100.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 5222); common length : 75.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 5450); 最大体重: 9.0 kg (Ref. 3132)
背棘 (总数) : 11; 背的软条 (总数) : 15 - 17; 臀棘: 3; 臀鳍软条: 8. Distinguished by the following characteristics: color is dark purplish gray with scattered irregular whitish spots and blotches which are faint or absent in preserved fish; ctenoid body scales except cycloid dorsoanteriorly below anterior half of spinous dorsal fin, thorax, abdomen and above anterior anal fin; body with numerous auxiliary scales; greatest depth of body 2.5-3.0 in SL; slightly emarginate to truncate caudal fin; short pelvic fins, 1.7-2.3 in head length (Ref. 90102); head length 2.4-2.7 times in SL; distinctly convex interorbital, slightly convex dorsal head profile; subangular preopercle, shallow notch just above the angle, serrae at angle not or slightly enlarged; upper edge of operculum straight; posterior nostrils of adults is twice the size of anterior nostrils; maxilla reaches vertical at rear edge of eye or thereabouts; ventral edge of maxilla of adults with distinct step distally; 2 rows of teeth on midlateral part of lower jaw (Ref. 89707).
色彩是深色的带紫色的灰色有分散的不规则的微白色的斑点与斑块那是模糊的或者不存在于保存的标本。
Inhabit clear to turbid water in shallow as well as deep water (Ref. 4787). Juveniles are found in inshore coral reefs (Ref. 5222). They feed in water to more than 100 m depth (Ref. 27275). It has been suggested that juveniles mimic the herbivorous damselfish Neopomacentrus sindensis, presumably to get closer to their unsuspecting prey (Ref. 5222, 9710). Feed on small fishes and crabs. Probably spawn during restricted periods and form aggregations when doing so (Ref. 27352). Eggs and early larvae are probably pelagic (Ref. 6390). Solitary (Ref 90102).
在浅滩中栖息于清澈至浑浊的水以及深水域.(参考文献 4787) 稚鱼被发现于近萨达姆瑚礁。 (参考文献 5222) 他们在水到超过 100 公尺深中觅食。 (参考文献 27275) 它有被显示出拟态被可能的食草的雀鲷 辛德新雀鲷［Neopomacentrus sindensis］ 的稚鱼更靠近他们的未察觉猎物.(参考文献 5222,9710) 捕食小鱼与螃蟹。 在限制的期间可能产卵而且形成鱼群当这么做的时候.(参考文献 27352) 卵与初生仔鱼可能大洋性。 (参考文献 6390)
