背棘 (总数) : 7; 背的软条 (总数) : 35 - 39; 臀棘: 1; 臀鳍软条: 33 - 37; 脊椎骨: 26. Pale blue to yellowish; upper abdomen with a broad area of deeper blue; a bar, broad and blackish extending ventrally from eye onto chin; iris yellow, upper and lower edges broadly deep blue; postorbital head with irregular, iridescent markings. A single, continuous dorsal fin with spinous part lower than soft portion. Chin with fleshy protuberance narrowing to a thin low, median fold. Scales very small, fully embedded and well separated. Named as such in reference to its continuous dorsal fin.
蓝灰色到淡黄色的; 上面的腹部有一个较深的蓝色的宽区域; 一条横带, 宽而黑色的延伸腹地从眼在下巴之上; 虹膜黄色又上、下边缘宽广深的蓝色; 眼眶后的头部有不规则又彩虹色的斑纹。 一, 连续的背鳍有硬棘的部分低于柔软部位。 下巴有对细的低又中央的折层狭窄的肉质的突起。 鳞片非常小的, 完全深入的而且分得很开。 关于它的连续背鳍同样地命名。
Lives in reef habitats from shallow coastal slopes to outer reef lagoons and slopes below drop-offs to 50 meters, among rubble (Ref. 48637). Occurs in pairs and its burrow may be in coral rock or sand. Monogamous (Ref. 52884). Feeds on zooplanktons (Ref. 89972). They tend to form large, though diffuse, colonies; may be due to a propensity to aggregate or may be a result of the ecological requirements for the species (for which type of substratum, current pattern, and water depth among the most important) which restrict the areas of settlement of the postlarvae.
在对 50 公尺的海峭壁之下生活在礁石栖地从浅水的海岸斜坡到外围礁石舄湖与斜坡, 在碎石之中。 (参考文献 48637) 成对出现与它的洞穴可能在珊瑚礁或沙子中。 一夫一妻的.(参考文献 52884) 他们趋向形成大的, 分散的, 集群; 对于限制后期幼体的沈降的区域的此鱼种 (为是那一个类型的下层土壤, 水流类型与水深度是最重要的因素之一) 可能由于一个群集的习性或者可能是生态上的需求的一个结果。
