Short description Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt): 1; Mjukstrålar i ryggfenan (totalt): 7; Taggstrålar i analfenan 0; Mjukstrålar i analfenan: 10 - 11. Body elongate and compressed; head conical; occipital process narrow. Maxillary barbels, in adults, extend posteriorly beyond the caudal fin base, but in young specimen, do not extend beyond the anal fin. Dorsal spine weak, often feebly serrated. Color is grayish with a more or less well-defined midlateral longitudinal stripe. A dark spot emphasized by a white or pale area along its ventral margin is just anterior to the first dorsal spine. Dorsal, adipose and caudal fins shaded with melanophores.

Biologi     Ordlista (t.ex. epibenthic)

Found in tidal rivers and lakes; also beels, canals, ditches, ponds, and inundated fields. Its pectoral spine can cause painful wounds (Ref. 4833). Found in the basin-wide tributary of the lower Mekong (Ref. 36667). Oviparous, distinct pairing possibly like other members of the same family (Ref. 205).
