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.

Length at first maturity / サイズ / 重さ / 年齢
Maturity: Lm ?, range 13 - ? cm
Max length : 31.2 cm SL オス/雌雄の選別がない; (Ref. 9843)
背面の脊椎 (合計) : 0; 背鰭 (合計) : 14 - 17; 肛門の骨: 0; 臀鰭: 13 - 17; 脊つい: 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.
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).
