简单描述 型态特徵 | 形态测量图

背棘 (总数): 12 - 13; 背的软条 (总数): 7; 臀棘 3; 臀鳍软条: 9. This species is distinguished by the following characters: body deep, its depth 2.4-2.7 times in standard length; dorsal profile of head convexly curved above eyes; anterior tip of head forming a broad angle with snout steeply inclined; jaws prominent; 4 strong canines situated anteriorly in each jaw with second pair in lower jaw directed laterally; an enlarged canine present on each side at rear of upper jaw; D XIII,7, continuous with spines and anterior soft rays of similar length; A III,9; pectoral fins with ii unbranched and 13-14 branched rays; pelvic fins not filamentous; caudal fin truncate to slightly rounded; lateral line continuous, smoothly curved, with 29 pored scales; scales barely reaching onto bases of dorsal and anal fins; scales in front of dorsal fin distinctly not extending forward to above eye; cheek and opercle scaly, scales on preopercle small, less than 1/4 the size of those on body; lower jaw without scales. Colour of body greenish to grey with underside of head, chest and lower portion of sides white or bluish; a wedge-shaped white band extending upward onto back behind pectoral fins; a large rectangular white saddle situated dorsally on caudal peduncle extending forward below rear of dorsal fin; head speckled with orange; pectoral-fin base covered by a large blue to black spot; dorsal fin greenish grey anteriorly and yellowish posteriorly; caudal fin greenish orange; anal fin yellow with orange markings; a narrow blue margin on dorsal and anal fins. Small individuals overall greenish grey with several whitish bars (Ref. 9823).
一对明显增大犬齿出现在颚的前面。 历经颜色随着成长很少的改变。 成鱼能被辨识特徵为腹面的白色下面与头部。 稚鱼是呈绿色的当在海草中.(参考文献 48636)

生物学特性     字汇 (例如 epibenthic)

Adults inhabit reef flats and lagoon reefs, in areas with seagrass or mixed sand, rubble, and coral (Ref. 9710). They often form small aggregations (Ref. 8631). Juveniles occur inshore and usually form small groups in estuarine seagrass beds. Adults can be found in inner as well as outer reefs and are territorial (Ref. 48636). Feed mainly on hard-shelled prey including crustaceans, mollusks and sea urchins. Oviparous, distinct pairing during breeding (Ref. 205). In Hong Kong live fish markets (Ref. 27253).

栖息于礁石平台与泻湖礁, 在有海草或混合的沙子,碎石与珊瑚的区域中.(参考文献 9710) 时常形成小群鱼群.(参考文献 8631) 稚鱼出现沿海地区而且通常形成河口的海草床的小群鱼群。 成鱼被发现于在内部的以及外海岩礁而且是具有领域性.(参考文献 48636) 主要吃具有硬壳的猎物包括甲壳动物,软件动物与海胆。 在香港活鱼贩售。 (参考文献 27253)
