If all you know about sailfish is that plastic trophy above your uncle's fireplace, prepare to have your mind blown. In this mesmerizing video filmed off the coast of Mexico's Isla Mujeres, a group of sailfish herd a "bait ball" of sardines, taking turns rushing up to it for bites of fish.
Photographer Sarosh Jacob recalled the moment when one frenzied sailfish charged straight at him and his friend: "At the last second, the sailfish turned just enough to miss my face," he told Stuart Magazine. "Imagine this 8-foot sailfish literally 'threading the needle' in the space between our heads. It was so close we both stopped shooting and looked at each other in shock."
With their iridescent blue spots and raised "sails" -- all the better to look bigger and scarier to terrified little fish -- these graceful hunters prove why they deserve their billing among the ocean's top predators.
