Etymology: Tylosurus: Greek, tylos = callus + Greek, oura = tail (Ref. 45335).
Taxonomic Remarks
Considered mostly as a subspecies in the literature. Therefore the upraise at species rank here is considered as a provisionally accepted name, until more works are conducted on T. acus susbepcies to fix their status.
