Short description
पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स
पृष्ठीय रीढ़ (सम्पूर्ण) : 7; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 10 - 11; गुदा कांटा: 1; ऐनल सौफट रेज़: 10. This species is distinguished by the following characters: predorsal midline no scales; fifth pelvic-fin ray unbranched; cheek with 6 papillae in row c; at least some inner pectoral-fin rays are branched; second spine of first dorsal fin extending posteriorly only to interspace between two fins; an interorbital trench that fades out between fifth and sixth papillae of row p. Colouration: no red bars across body; when alive, head with three blue stripes, one dorsal midline, second from top of orbit to near upper lip, and third across dorsal margin of preoperculum, lower part of iris, and across lips meeting counterpart at ventral midline, the intervening area on head red dorsally grading to yellow and light purplish ventrally, and body with many melanophores on a dirty yellow background; when preserved, blue lines on head are black (Ref. 131294).
Occurs in pairs or small groups. Sightings of this species suggest that it inhabits crevices (containing a mix of red coralline algae, Halimeda sp., Tubastrea coccinea, sponges and ascidians) and caves in steep sloping reefs deeper than 18-20 m. It has only been seen in such steep-sloping, coral-rich habitats on outer reefs facing open ocean. It was not observed during exploration of similar depth ranges around the same atolls in areas with different bathymetry and substrate type (very little coral, dominated by rock and algae, with gradual slopes). (Ref. 131294).
