Description
The swordfish is a large, powerful oceanic predator of the family Xiphiidae that can reach about 4.5 metres. Characteristic is the upper jaw extended into a long, flat sword, with which the fish injures and scatters prey schools. The streamlined body is dark above and paler below and, as an adult, lacks scales and pelvic fins. The swordfish is partly warm-blooded, allowing it to stay active in cold, deep water; by day it dives hundreds of metres, at night it hunts higher in the water column for squid and schooling fish. It lives oceanically in warm and temperate seas worldwide. Due to heavy fishing it is assessed as Near Threatened (NT) and is a prized sport and food fish.
