Scale rows on back rising obliquely above lateral line. Back and upper sides vermilion, shading to silvery with reddish tinge ventrally, with narrow horizontal yellow lines below the lateral line. The dorsal and caudal fins yellowish; the anal and pelvic fins whitish.
吻短, 下颌些微突出。 嘴小的。 胸鳍相当短的, 不达到肛门高度。 鳞片列背面斜向上升在侧联机面。 背面与上侧面朱红, 颜色变化成腹地银色的有淡红的淡色, 在侧线之下有狭窄的水平黄线。 背鳍与尾鳍淡黄色的; 臀鳍与腹鳍鳍微白色的。
Adults are found in moderately deep waters, most common over rock, gravel or sand bottoms near the edge of the continental and island shelves, often in large schools. Young fish occur in shallower depths (below 25 m), also often forming large schools. They feed on fishes, shrimps, crabs, polychaetes, other benthic invertebrates, cephalopods and planktonic organisms. Good food fish (Ref. 9626).
发现于中等深度的水域了, 最常见的在大陆架与岛屿架的边缘附近的岩石，砾石或砂质底部之上。 幼鱼出现在深度较浅的地方。 (在 25 公尺之下) 时常形成大群鱼群, 特别地幼鱼。 吃鱼，虾，螃蟹，多毛类动物, 其他的底栖无脊椎动物，头足类动物与浮游生物生物。 好食用鱼.(参考文献 9626)
