A swordfish (Ameki, Aokiki, scientific name Xiphias gladius) is a kind of swordfish classified in the perch swordfish family. It is the largest of the marlins and is caught for food. It is the only living species of the swordfish family and the only species of the swordfish genus. The fossil fish Protosphyraena has a similar form but is not a related species (previously considered an ancestor of barracuda or swordfish, but is now denied).
