توصيف مختصر
ريخت شناسي | ريخت ستجي بوسيله انداره گيري
خارهاي باله پشتي (کل): 7; شعاع نرم باله پشتي (کل): 113; خارهاي باله مخرجي 1; شعاع نرم باله مخرجي: 10 - 12; مهره ها: 26. This species is distinguished by the following characters: D VI + I,11-13 (rarely 13), the spines of first dorsal fin with protruding filaments; A I,10-12 (rarely 12); pectoral-fin rays 18-19; scales in longitudinal series 52-58; total gill rakers on first arch 15-16; segmented caudal-fin rays 17; branched caudal-fin rays 11; forked caudal fin with filament on upper and lower lobe; no preopercular pores; interorbital pores paired; colour in life semi-translucent grey with yellowish hue; with short yellow stripe on snout and from upper eye to pectoral-fin base; blue stripe from mid-interorbital to first dorsal-fin origin; dorsal fins are translucent with yellowish hue, both dorsal fins have prominent basal and submarginal blue stripes; caudal fin yellowish to yellow-brown with blue upper and lower margins (Ref. 105381).
Form loose aggregations of 10-50 individuals, observed hovering 50-100 cm above the substrate on a very gradual but strongly current-swept sand and rubble slope in 28-31 m depth. Collection reef with visibility invariably quite low (5-8 m maximum) and where there was frequently a minor thermocline at the 20-25 m depth range, with the fish exposed to moderately cooler temperatures down to 27°C. When approached too closely, individuals would dive into burrows in the sand, sometimes individually but also multiple individuals entering the same burrow (Ref. 105381).
