The morphometric characteristics that separate white marlin Kajikia albidus from roundscale spearfish Tetrapturus georgii can be difficult for non-experts to distinguish, particularly when the animals are in the water. Using the measurements of the lower jaw tip to the longest branchiostegal ray (LJBR) and the opercle (LJOP), a discriminant function is presented that will help field observers separate the two species. The function DR-W = LJBR (3.31861) + LJOP (-2.84856) – 6.37198 classified specimens as roundscale spearfish when DR-W was > 0 and as white marlin when DR-W < 0 with a 95% correct classification rate overall. Since only the head of a specimen needs to be closely observed, the method has particular utility for tournament anglers during the hook removal process.
