简单描述 检索表 | 型态特徵 | 形态测量图

背棘 (总数) : 7 - 9; 背的软条 (总数) : 26 - 33; 臀棘: 2 - 3; 臀鳍软条: 22 - 28. This species is distinguished by the following characters: head broad and depressed; first dorsal fin usually with VIII short but strong isolated spines, not connected by a membrane; caudal fin lunate to emarginate in adults, upper lobe longer than lower, rounded in young with prolonged central rays. Colour of back and sides dark brown, with 2 sharply defined narrow silvery bands, belly yellowish (Ref. 10948, 90102).
头部宽且侧扁。 第一背鳍有短但是强的分离硬棘, 不连接经由一个膜。 尾鳍新月状的当成鱼时, 上叶比下叶长。 背面与侧边深褐色的, 有两个轮廓分明的狭窄银色的条纹。

生物学特性     字汇 (例如 epibenthic)

Adults occur in a variety of habitats, over mud, sand and gravel bottoms; over coral reefs, off rocky shores (Ref. 10948) and in mangrove sloughs; inshore around pilings and buoys, and offshore around drifting and stationary objects; occasionally in estuaries (Ref. 9739). Form small groups and may pursue small pelagic inshore (Ref. 48635). Feed on crabs, fishes, and squids (Ref. 5213, 10948, 13442). Form spawning aggregations during the warm months in the western Atlantic; eggs and larvae planktonic (Ref. 12459). Caught in small quantities due to its solitary behavior (Ref. 9626). Caught mainly with handlines, and by trolling pelagically offshore over the continental shelf (Ref. 10948). Good food fish; marketed fresh (Ref. 5284), smoked, and frozen (Ref. 9987). Also caught for sport (Ref. 26938).

出现于多种栖息地,在泥之上,沙与碎石底部; 在珊瑚礁,外海的岩岸 (参考文献 10948) 之上与在红树林泥坑中; 桩材与浮标的周围沿海地区, 与漂流与静止的目标周围的外海; 偶见于河口。 (参考文献 9739) 形成小群鱼群而且可能追逐小型大洋性鱼类沿海地区.(参考文献 48635) 吃螃蟹,鱼与乌贼。 (参考文献 5213,10948,13442) 在大西洋西部中产卵于温暖的个月; 卵与仔鱼为浮游性.(参考文献 12459) 捕获量很少由于它的独居性行为.(参考文献 9626) 好食用鱼; 在市场上销售生鲜地 (参考文献 5284),烟熏了, 与冷冻.(参考文献 9987) 也游钓捕获。 (参考文献 26938)
