Atlantic Ocean: in tropical and temperate waters approximately 40°N in the northwest Atlantic, 50°N in the northeast Atlantic, 40°S in the southwest Atlantic, and 32°S in the southeast Atlantic. Migrating to Mediterranean Sea, mostly based on juvenile specimens. Highly migratory species, Annex I of the 1982 Convention on the Law of the Sea (Ref. 26139). Some authors recognize a single worldwide species, Istiophorus platypterus (Shaw 1792) but we follow Nakamura 1990 (Ref. 10820) retaining the usage of Istiophorus platypterus for the Indo-Pacific sailfish and Istiophorus albicans for the Atlantic sailfish in recognition of differences between them.
Usually found in the upper layers of warm water above the thermocline, but also capable of descending to rather deep water. Often migrate into near-shore waters. Occasionally form schools or smaller groups of 3 to 30 individuals, but often occur in loose aggregations over a wide area. Feed mainly on small pelagic fishes but also takes bottom-dwelling organisms. Females grow larger (Ref. 4770). Utilized fresh, canned and frozen; eaten steamed (Ref. 9987).
