Eponymy: Jean René Constant Quoy (1790–1869) was a French naval surgeon and zoologist who named many species, often with Joseph Paul Gaimard (q. [...] (Ref. 128868), visit book page.

Könsmognad: Lm ?, range 13 - ? cm
Max length : 31.2 cm SL hane/ej könsbestämd; (Ref. 9843)
Taggstrålar i ryggfenan (totalt) : 0; Mjukstrålar i ryggfenan (totalt) : 14 - 17; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 13 - 17; Ryggkotor: 51 - 56. Prolonged, beak-like lower jaw, shorter than head length, its length contained in 4.7-8.6 times in SL and 1.2-2.0 times in head length; upper jaw short, scaly, blunt and rounded, its width contained in 0.5-0.6 times in its length; preorbital bone 1.75-2.15 times in diameter of orbit and 0.9-1.15 times in length of upper jaw; preorbital ridge present; posterior branch to preorbital lateral line canal present. Total number of gill rakers on first arch 26-39; dorsal fin rays 14-17, usually 16; anal fin rays 13-17, usually 15 or 16. Caudal fin forked, with lower lobe longer than upper.
Body shape (shape guide): elongated.
Inhabits more turbid and estuarine situations than does Hyporhamphus dussumieri and is not found in oceanic islands (Ref. 9843). May enter rivers (Ref. 559). Found in medium to large-sized rivers of the lower Mekong (Ref. 12975). Occurs in schools (Ref. 3132). Taken mostly with shore seines; marketed mostly fresh and dried salted (Ref. 9843).
