Descripción breve
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 17 - 19. Distinguished from its congeners by having unique characters of 3 discontinuous dark stripes along flank and 55-62 + 4-5 scales along lateral line. Differs further from other species of the genus by having 17-19 dorsal spines (Ref. 59043).
Body shape (shape guide): fusiform / normal.
Adults occur in groups in open sand and mud bottom of large rivers with moderate current. Nocturnal, feeding on small invertebrates, especially molluscs, usually crepuscular but may also feed at daytime. Larvae are benthic (Ref. 59043).
