Descripción breve
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 0; Espinas anales: 0; Radios blandos anales: 20 - 22. Body slender, oval in cross-section. Snout long and pointed; maxilla short, tip bluntly rounded, not reaching to front border of pre-operculum, not projecting beyond tip of second supra-maxilla; teeth in jaws minute or absent. gill rakers long and slender, absent on face of third epibranchial. Dorsal fin origin at about midpoint of body; anal fin origin under last dorsal fin ray (Ref. 189). Olive above, silvery on sides and below. Snout blackish above. Fins pale orange; caudal rays blackish at tips (Ref. 37032).
Body shape (shape guide): elongated; Cross section: compressed.
Occurs in middle and upper reaches of rivers. The numerous and rather long gillrakers armed with fine setae, together with the very long and highly coiled gut suggest a microplanktonic diet. More data needed.
