In the Whirl.
Adorned for the hunt, with fin raised and changeable colors
flashing, a sailfish in the Gulf of Mexico circles a ball of
sardines, preparing to strike.

My contact at National Geographic magazine sent a link to an interesting story about billfish (sailfish) to share with you and she also gave me permission to use the incredible images of billfish (sailfish) that are there to see. They also have a video that shows how these fish make a “bait ball” that you will be fascinated with.
