This species is characterized by having 4 soft dorsal- fin rays, 54–74 soft anal-fin rays, 2 pairs of barbels; maxillary barbels reaching pelvic fins or anal fins; man- dibular barbels diminute, about as long as eye diameter; small eyes covered by skin; dorsal and pelvic fins small; anal fin long; pectoral fins well developed ( Taki 1974) and presence of vomerine teeth in 2 patches ( Rainboth 1996). The color body is brown, usually marmorated color body with conspicuous round black blotch above pectoral-fin base ( Kottelat 2001). Ompok siluroides dif- fers from O. bimaculatus by having rounded head and a mottled brown coloration of the body (vs sharped head, and gray coloration of the body). This species inhabits streams and rivers of all sizes with currents ranging from sluggish to moderate; it moves into freshly inundated habitats during the flood season. These fish feed on crus- taceans and mollusks ( Rainboth 1996).
