Maturity: Lm ?  range ? - ? cm
Max length : 25.0 cm TL male/unsexed; (Ref. 556); common length : 15.0 cm TL male/unsexed; (Ref. 556)
Diagnosed from its congeners by the possession of the following characters: lateral line usually with 30-38 + 2-3 scales; 3-4 (usually 3) scale rows between lateral line and pelvic fin origin; 11-12 circumpeduncular scale rows; eye diameter smaller than snout length; snout rounded, obtuse; and ventral profile of head with a marked angle at articulation of lower jaw (Ref. 59043).
Occur in coastal rivers and terminal segments of main rivers. Adults are found commonly in lower reaches of rivers (Ref. 59043). Threatened due to pollution and habitat destruction (Ref. 26100).
