The Atlantic Sailfish (Istiophorus albicans) is a species of marine fish in the family Istiophoridae of the order Perciformes. The Atlantic sailfish is related to the marlin.
The Atlantic sailfish is a pelagic fish of tropical and temperate waters in the Atlantic Ocean. It ranges from approximately 40°N in the northwestern Atlantic to 40°S in the southwestern Atlantic, and 50°N in the northeastern Atlantic to 32°S in the southeastern Atlantic. It is a migratory species and moves about the open ocean and into the Mediterranean Sea. Its depth range is from warm surface waters down to about 200 m (656 ft).
It is found in the Atlantic Oceans and the Caribbean Sea, except for large areas of the central North Atlantic and the central South Atlantic, from the surface to depths of 200 m (656 ft).
Tests in the 1920s estimated that the Atlantic sailfish was capable of short sprints of up to 111 kilometers per hour; however, more conservative estimates of 37 to 55 kilometers per hour are more widely accepted. Atlantic sailfish hunt schooling fish, such as sardines, anchovies and mackerel although they also feed on crustaceans and cephalopods.
