简单描述 型态特徵 | 形态测量图

背棘 (总数): 11; 背的软条 (总数): 14-16; 臀棘 3; 臀鳍软条: 10 - 12. Distinguished by the following characteristics: brownish or dark grey body color of adults with irregular pale blotches and spots and prominent maxillary streak (capable of reversing body color pattern when under stress); juveniles mottled greenish brown, with prominent white spots on head and body, median fins with white streaks and hyaline golden pectoral fins; oblong and compressed body, depth 3.0-3.3 times in SL; head length 2.6-2.9 times in SL; convex interorbital area; enlarged serrae of preopercle at the angle, forming rounded lobe below shallow indentation on vertical limb; few small serrae on subopercle and interopercle; subequal sizes of anterior and posterior nostrils in juveniles, adults with 3 times larger posterior nostrils compared to anterior ones; lower jaws extends well in front of upper jaw (Ref. 89707).

生物学特性     字汇 (例如 epibenthic)

Adults occur near the bottom in rocky areas; juveniles are found in tide pools (Ref. 89707). Two specimens collected from the Cape Verde by J. Cadenat were from a depth of '50' m.

在岩石区中生活于靠近底部; 稚鱼被发现于潮池。 采集自 J. Cadenat 的维德角的二件标本是从深度 1950' 公尺。
