Females are larger than males, and Pacific swordfish reach a greater size than northwest Atlantic and Mediterranean swordfish. The International Game Fish Association's all-tackle angling record for a swordfish was a 536 kg (1,182 lb) specimen taken off Chile in 1953. They commonly reach 3 m (10 ft) in length, and the maximum reported is 4.55 m (14 ft 11 in) in length and 650 kg (1,430 lb) in weight. Unlike modern taxa these have equally long lower jaws. Several extinct genera are known, such as a large sized Xiphiorhynchus and Aglyptorhynchus. This makes it superficially similar to other billfish such as marlin, but upon examination, their physiology is quite different and they are members of different families. The species name, Xiphias gladius, derives from Greek ξιφίας ( xiphias, "swordfish"), itself from ξίφος ( xiphos, "sword") and from Latin gladius ("sword"). The swordfish is named after its long pointed, flat bill, which resembles a sword. They are the sole member of their family, Xiphiidae. These fish are found widely in tropical and temperate parts of the Atlantic, Pacific, and Indian Oceans, and can typically be found from near the surface to a depth of 550 m (1,800 ft), and exceptionally up to depths of 2,234 m. ![]() Swordfish are elongated, round-bodied, and lose all teeth and scales by adulthood. They are a popular sport fish of the billfish category, though elusive. Swordfish ( Xiphias gladius), also known as broadbills in some countries, are large, highly migratory predatory fish characterized by a long, flat, pointed bill.
