deskripsi pendek
Kunci identifiaksi (pengenalan) | Morfologi | Morfometrik
Duri punggung (Keseluruhan (total)) : 13; duri punggung lunak (Keseluruhan (total)) : 10 - 13; Duri dubur: 2; Sirip dubur lunak: 9 - 11; vertebrata, bertulang belakang: 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).
Cross section: compressed.
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).
