Pacific Ocean: ranging eastward to the Gilbert Islands and Samoa, north to southern Japan. Confused with Hemiramphus archipelagicus under the name Hemiramphus marginatus by many authors (Ref. 10943).
太平洋: 向東延伸到吉柏特島與美屬薩摩亞, 北至日本南部。 與 Hemiramphus archipelagicus 被稱為許多作家的 Hemiramphus marginatus互相混淆了.(參考文獻 10943)

Greatly prolonged, beak-like lower jaw; upper jaw short, triangular and without scales; preorbital ridge absent; total number of gill rakers on first gill arch 33-46; pectoral fins long, reaching beyond anterior margin of nasal pit when folded forward; no spots or vertical bars on sides.

Inhabits coastal waters rich in vegetation (Ref. 5213). Found more offshore than other species of Hemiramphus in the western central Pacific; juveniles and immature individuals are relatively common far from shore, usually among floating plants (Ref. 9843). Caught by set-net.
栖息于沿岸水域丰富的在植物.(参考文献 5213) 在中太平洋西部发现于更外海胜于其他种的 Hemiramphus; 稚鱼与不成熟的个体是相当普遍的远离海岸, 通常在漂浮的植物之中.(参考文献 9843) 被定置网捕获了。
