Description

The shortbill spearfish is a large, fast predatory fish of the billfish family (Istiophoridae) found worldwide in tropical and subtropical oceans. The species reaches about 230 cm and has a streamlined, blue-black body with a long dorsal fin and a short, spear-shaped upper jaw, the shortest bill of all billfishes. It is oceanic and epipelagic, staying above the thermocline. The fish hunts fishes, squid and crustaceans. It is caught mainly as bycatch of tuna longline fisheries and processed in Japan into fish cakes, sashimi and sausages. The IUCN has insufficient data (DD).
