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.
Body shape (shape guide): elongated; Cross section: compressed.
Adults live in reef habitats from shallow coastal slopes to outer reef lagoons and slopes below drop-offs to 50 meters, among rubble (Ref. 48637). They occur in pairs and their burrows may be situated in coral rock or sand. Monogamous (Ref. 52884). Adults feed on zooplankton (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.
