Swordfish (Xiphias gladius) are large, highly migratory, predatory fish characterized by a long, flat bill in contrast to the smooth, round bill of the marlins. Swordfish are elongate, round-bodied, and lack teeth and scales as adults. They reach a maximum size of 14 ft (4.3 m) and 1,190 lb (540 kg). The International Game Fish Association’s all-tackle angling record is a 1,182 lb (536 kg) fish taken off Chile in 1953.
They are the sole member of their family Xiphiidae.
The swordfish is known as The Gladiator (gladius) because of the sharp, sword-like bill it wields as a weapon
