Tylosurus acus (keel-jawed needlefish) is a game fish of the family Belonidae.
The keel-jawed needlefish is widespread in the Atlantic and Indo-Pacific oceans.[2]
There are four recognised subspecies of Tylosurus acus:[1]
Tylosurus pacificus was once considered a subspecies of T. acus but is now considered a distinct species.[3] Although acus was suppressed by ICZN Opinion 900, continued usage of the name led to Tylosurus acus being reinstated as a valid name.[4][5] Some authorities raise the four subspecies to species level.[6]
