Short description
आकृति विज्ञान | मौरफोमैटरिक्स
पृष्ठीय रीढ़ (सम्पूर्ण): 13; पृष्ठीय सौफट रेज़ (सम्पूर्ण): 10-13; गुदा कांटा 2; ऐनल सौफट रेज़: 9 - 11; जानवरों की रीड़ का जोड़: 26. This species is distinguished by the following set of characters: D XIII,10-13 (usually XIII,12); A II,9-11 (usually II,10); pectoral-fin rays 17-20 (usually 18-19); spiniform caudal-fin rays 2; tubed lateral-line scales 17-19 (rarely 17); total gill rakers on first branchial arch 29-34 (usually 31-32); body depth 2.1-2.4 (mean 2.2) in SL. Colouration: in life yellowish brown on dorsal head, nape, spinous dorsal fin, and back, grading to gray-brown on sides, with a prominent saddle-like white spot near the base of last dorsal-fin rays extending onto upper caudal peduncle; brownish bands edged with white along the upper and lower margins of caudal fin (Ref. 125611).
Usually found on the outer slope of coral reefs and on gradually sloping or flat bottoms of trawling grounds, presumably around rock outcrops, sponges, and sea fans (Ref. 125611).
