Etymology: Hyporhamphus: Greek, hypo = under + Greek, rhamphos = beak, bill (Ref. 45335).
Eponymy: Benoit Gernart (ca: 1797–1843) was French Consul-General in China based in Canton (1827–1837), and later in West Java and at Macao where he obtained the halfbeak. (Ref. 128868), visit book page.

Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt) : 0; Rückenflossenweichstrahlen (insgesamt) : 13 - 15; Afterflossenstacheln: 0; Afterflossenweichstrahlen: 14 - 17; Wirbelzahl: 51 - 53. Long recurved unicuspid teeth arranged in only 1-2 rows in the anterior parts of both jaws. Predorsal scales 35-40; pelvic fins located closer to the origin of the pectoral fin so that the P2-C distance extended forward reaches the orbit. Lower jaw about equal to head length.
A coastal water species.
