Swordfish, also called broadbills, are large and highly migratory or predatory fish identifying by the long and flat bills. It is a well-known billfish category though elusive. It is round-bodied, elongated, and loses all teeth or scales by adulthood. It is widely found in temperate and tropical parts of the Atlantic, Indian, and Pacific Oceans and is typically found from near-surface to depth of 550 m (1,800 ft). Usually, it measures 3 m (9.8 ft) in length and the maximum length reported is 4.55 m (14.9 ft) weighing 650 kg (1,430 lb) in weight.

It is the exclusive member of the family Xiphiidae. They are formidable predators. It has acute? eyesight which helps them to address prey and its flesh is comprised of white muscle providing energy for sudden bursts of activity when chased its prey. Then swordfish uses its bill to impale or stun its victim, lacerate it into pieces, or might swallow it whole. It feeds during the day mainly on squid but also fish and crustaceans infrequently. It undertakes vertical migrations in the ocean and follows the movement of small fish, shrimp, and squid which moves with changing the intensity of light for avoiding predators. It is unable to maintain a higher body temperature than the temperature of surrounding water. But they have uncommon muscle and brown tissue which warms blood flowing to the eyes and brain that helps to enable them to tolerate the extreme cold of ocean depths. They undertake lengthy seasonal migrations, to cold or temperate waters in summer where it feeds and returns back to warm waters for spawning in autumn.

The spawning occurs year-round in warm equatorial waters and it occurs in cooler regions in spring and summer. The finest spawning grounds are found in the Mediterranean sea, Sicily, and south of the Italian Peninsula. Eggs are found from June to September and juveniles occur throughout the Mediterranean from November to March. The fertilization is external. Female releases buoyant eggs in millions into the water which are fertilized by sperm secreted by males. Larvae hatch from fertilized eggs. In the first year of life, larvae grow at an exceptional rate reaching 90 centimeters long. Female reaches maturity at 150 centimeters and male around 100 centimeters.

The adult is scaleless and has no teeth. Females live longer and grow larger in comparison to males.

Reproduction

Throughout the year, spawning occurs in equatorial water but at higher latitudes during spring and summer. As external fertilization takes place, solitary males and female pairs during spawning. The egg varies from and 29 million in a 2,72,000 g female and 1 million to 16 million in 1,68,000 g female. The spawning occurs in the Atlantic Ocean at depths between 0 and 75 m with temperatures around 23 °C and salinity of 33.8 to 37.4 ppt. But in the Pacific Ocean spawning occurs in water having a temperature of 24°C or more.
