Size / Weight / Age

Max length : 348 cm FL male/unsexed; (Ref. 40637); common length : 270 cm TL male/unsexed; (Ref. 9308); max. published weight: 100.2 kg (Ref. 40637); max. reported age: 13 years (Ref. 53742)

Environment

Marine; pelagic-oceanic; oceanodromous (Ref. 51243); depth range 0 - 200 m (Ref. 54238), usually 30 - ? m (Ref. 9688)

Climate / Range

Subtropical; 50°N - 43°S, 180°W - 180°E (Ref. 43)

Distribution

Indo-Pacific: tropical and temperate waters approximately 45°- 50°N and 40°-35°S in the western Pacific, 35°N and 35°S in the eastern Pacific; 45°S in western Indian Ocean and 35°S in eastern Indian Ocean. Entered Mediterranean Sea from Red sea via Suez Canal. 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 & Nodder 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 the differences between them.

Body elongate and compressed; upper jaw prolonged into a very long beak; two dorsal fins, the first very large and tail; pelvic fins narrow but very long, almost reaching anus, with 1 spine and 2 rays; body covered with small, embedded scales with 1 or 2 blunt points; back dark with about 20 bluish vertical bars; belly pale silver; membrane of first dorsal fin blue black with numerous dark spots (Ref. 55763). A slender billfish with a high, sail-like first dorsal fin (Ref. 26938).

Biology     Glossary (e.g. epibenthic)

Oceanic and epipelagic species usually found above the thermocline. Most densely distributed in waters close to coasts and islands (Ref. 9688). Most likely schools by size. Undergoes spawning migrations in the Pacific (Ref. 43). Feeds mainly on fishes, crustaceans and cephalopods. Utilized fresh, smoked and frozen; also used for sashimi and sushi; eaten broiled and baked (Ref. 9987).
