Swordfish (redirected from Sword Fish)

swordfish, large food and game fish, Xiphias gladius, of the warmer Atlantic and Pacific waters, related to the sailfish. It is named for its sharp, broad, elongated upper jaw, which it uses to flail and pierce its prey of smaller fish, rising beneath a school to kill and then devour. Swordfish breed as far N as Nova Scotia; they are often seen basking on the water's surface, and their fins are sometimes mistaken for those of sharks. They may reach 15 ft (457 cm) and 1,000 lb (450 kg); however, specimens half this size are considered large. Swordfish were formerly harpooned commercially but now are taken using long lines with multiple baited hooks. Conservation efforts are underway to rebuild depleted stocks. Swordfish are classified in the phylum Chordata, subphylum Vertebrata, class Osteichthyes, order Perciformes, family Xiphiidae.

swordfish

Species (Xiphias gladius) of prized food and game fish, found in warm and temperate oceans worldwide. A slender, scaleless fish, it has a tall dorsal fin and a long extension of the snout, used for slashing at prey. The “sword” is flat, rather than rounded as in marlins. The swordfish is also distinguished by its lack of teeth and pelvic fins. It is purplish or bluish above, silvery below, and grows as large as 15 ft (4.5 m) and 1,000 lb (450 kg). Though a popular food fish, it may have dangerous levels of mercury concentrated in its flesh.
