How Can Flying Fish Actually Fly?

Is it a bird? Is it a plane? No, it’s actually a fish. Strictly speaking though, flying fish do not really fly. They use their fins to help them glide through the air, but they do not flap them like wings. The fish developed this technique to help them escape predators in the water, but they cannot remain airborne for very long, because they need to return to the water to breathe.
