Four-Wing Flying Fish: The 45-Second Flight

A flying fish named Hirundichthys routinely clears six feet above the surface of the Philippine Sea, and once, researchers clocked a glide lasting forty-five seconds straight. With only a split-second gap between tail and sky, It launches at up to forty miles per hour chased by dorado-carnivorous fish that can leap after them. Those extra-long pectoral fins look like a gimmick until they unfold mid-leap, each stretching more than half the fish’s body length, catching an updraft even as waves crash beneath. But the real trick hides in the lower fins: this species unfolds a second set, doubling its “wings” and steering like a biplane, tipping and banking to dodge seabirds. In June 2008 near Okinawa, scientists measured one fish covering 655 feet through the air without ever beating its tail again. How does it stay airborne long enough to cross half a city block while its predators thrash below? Each time the fish nears the water’s surface, it slaps its tail back through the waves, adding bursts of speed while never fully landing-so Hirundichthys can glide for forty-five seconds, farther than any other fish ever recorded.
