The fish also has a long, pointed bill. Sailfish are dark blue on the back with a white or silvery underside.
Sailfish live in ocean waters throughout much of the world.
Sailfish normally eat smaller fish and squid. They use their long bills to stun prey. Occasionally, people have observed groups of sailfish working together to capture prey. Female sailfish lay several million eggs, but only a few of the young survive into adulthood. Sailfish rank as popular game fish.
