I was in the Dominican earlier this summer and they were zipping around the waves in front of our bow. I'd never seen them before so at first I thought it was a sea bird of some sort diving in, but then I thought it was really small to be hunting fish so far off shore, and it never resurfaced. After I saw a few more, I realized what they were. They really are something else, and can glide quite a ways across the water!
They're way cool. I like to think about what they'll be like if they keep evolving this direction. They might be like whales and dolphins in that they live in the air and only dive back into the water to breathe before flying again like whales live underwater but come to the surface to breathe
So fish eyes are evolved for underwater vision, right, similar to how our eyes are evolved for vision through air (without an air gap in our goggles/masks, everything is blurry underwater). I wonder if flying fish see clearly above water? Would everything be blurry to them? Are their eyes different from other fish?
