背棘 (总数) : 1; 背的软条 (总数) : 6; 臀鳍软条: 11 - 15. Body elongated, without scales but with a range of 33-35 spiny bony plaque which runs along the length of the lateral, starting from the extreme end of the caudal fin up to the point directly below the origin of the dorsal fin. Head is pointed and laterally compressed, its width being far less than its length. Eyes are high and are situated in the posterior half of the head.

Can emit sounds by moving its pectoral spines. Every basic unit of sound emitted lasts for 60-70 millisecond, with a frequency of 60-90 Hertz corresponding to the reply frequency of the muscles utilized (Ref. 35381).
