Descripción breve
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 1; Radios blandos dorsales (total) : 6; Radios blandos anales: 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. Mouth is inferior, provided with a pair of maxillary barbels branching into 12 or 13 branches and 4 short mandibular barbels. Adipose fin short
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).
