Maturity: Lm ? range ? - ? cm
Max length : 12.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 48637)
背棘 (總數) : 7; 背的軟條 (總數) : 35 - 39; 臀棘: 1; 臀鰭軟條: 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.
藍灰色到淡黃色的; 上面的腹部有一個較深的藍色的寬區域; 一條橫帶, 寬而黑色的延伸腹地從眼在下巴之上; 虹膜黃色又上、下邊緣寬廣深的藍色; 眼眶後的頭部有不規則又彩虹色的斑紋。 一, 連續的背鰭有硬棘的部分低於柔軟部位。 下巴有對細的低又中央的摺層狹窄的肉質的突起。 鱗片非常小的, 完全深入的而且分得很開。 關於它的連續背鰭同樣地命名。
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.
成對出現與它的洞穴可能在珊瑚礁或沙子中。 一夫一妻的.(參考文獻 52884) 他們趨向形成大的, 分散的, 集群; 對於限制後期幼體的沈降的區域的此魚種 (為是那一個類型的下層土壤, 水流類型與水深度是最重要的因素之一) 可能由於一個群集的習性或者可能是生態上的需求的一個結果。
