Atlantic Smallwing Flyingfish

Adults with a single large chamber to the swim bladder. Average number of gill rakers on the first arch, 30.7; predorsal scales, 31.1 on the average. Branchiostegal rays: 11-14 (Ref. 36576).

Oviparous (Ref. 36576).

Oceanodromous. Migrating within oceans typically between spawning and different feeding areas, as tunas do. Migrations should be cyclical and predictable and cover more than 100 km.

Dorsal spines (total): 0; Dorsal soft rays (total): 13 - 15; Analspines: 0; Analsoft rays: 13 - 16; Vertebrae: 47 - 50

Found offshore (Ref. 9306). Also in Ref. 9137.

A true oceanic species, not bound to coastal waters at any period of its life (Ref. 9843).This species is the only halfbeak which doesn't have an extended lower jaw at the adult phase (Ref. 9306). Oviparous, with planktonic eggs and larvae (Ref. 36576).

廣泛分布於印度-泛太平洋區的熱帶及亞熱帶水域。臺灣分布於東部及東北部。

偶由流刺網、圍網、定置網等漁法捕獲，數量較少，較不具經濟價值。

體延長，側扁，標準體長為頭長之4.0-4.6倍。上頜短小，前緣平直，不明顯向前突出，無鱗；幼魚之下頜在發育過程中突出如喙，成魚時此喙退化消失，僅略較上頜突出。無眶前脊。第一鰓弓上鰓耙28-34。體被圓鱗；側線位低，於胸鰭基底下方具一向上分支，向上延伸至胸鰭基底；背前鱗28-32。鰾為單室型。背鰭與臀鰭對在，後位，臀鰭起點在背鰭第3-4軟條之下方，背鰭具13-15軟條，臀鰭具14-16軟條；胸鰭長於頭長，標準體長為胸鰭長之3.1-3.2倍，其末端幾達腹鰭基底上方；腹鰭短小，胸鰭基底至腹鰭基底之間距為腹鰭基底至尾鰭下葉基底之0.9-1.1倍；尾鰭深開叉，下葉遠長於上葉。體背呈淺灰藍，腹部白色。腹鰭後半部白色。另有一亞種/O. micropterus similis/ Bruun分布於大西洋熱帶海域。

純大洋洄游性魚種，會出現於近海，但不會出現於沿岸或島嶼四周的表層水域，或開放的港灣。一般皆成群洄游，容易受驚嚇，逃避敵害時，有時會有躍出水面的動作，甚至滑翔飛行。以水層中的浮游性生物或卵等為食。

Oxyporhamphus micropterus is a species of halfbeak found in the tropical oceans. Some sources elevate the two subspecies to species rank. Others classify it in the monotypic genus Oxyporhamphus. This taxon is found in the Indo-Pacific region where it is a pelagic, oceanodromous species. It was described by Achille Valenciennes as Exocoetus micropterus in 1847, with the type locality of King George Sound, Western Australia.
