Description

The Indo-Pacific sailfish is a large, fast predatory fish of the family Istiophoridae living in the tropical and subtropical Indian and Pacific Oceans. The species owes its name to the enormous, sail-like dorsal fin and bears a long, spear-shaped upper bill. The body is streamlined, dark blue above and silvery below, with pale vertical bars. It can reach about 3.5 m and is regarded as one of the fastest fishes in the world. It hunts fishes, crustaceans and squid in the upper water layers. The species is a prized target for sport fishing and is caught commercially.
