Bestämningsnycklar | Morfologi | Morfometri
This species is distinguished from its congeners by the following characters: osseous medial groove present; lateral margin of sphenotic notched, narrower medially than anteriorly;
fleshy medial groove of neurocranium, never surpassing posterior margin of eyes; pterotic lateral margin convex, sometimes angled; gill rakers on the first and second gill arches 30-36;
mouth narrow 9.7-12.7% SL; median portion of mesethmoid narrow, medial notch of mesethmoid narrow and deep; external posterior branch of lateral ethmoid columnar and thin;
fenestra delimited by mesethmoid and lateral ethmoid conspicuous (Ref. 116660).
Common in coastal marine and brackish waters (Ref. 9271). Inhabits medium and large rivers to an elevation of at least 25 m (Ref. 36880). Marketed fresh or salted (Ref. 9271). Aquarium keeping: not suitable for home aquarium; adults in seawater; minimum aquarium size >150 cm (Ref. 51539).
