I didn't know this poor flying fishes were living in hell. This preview of a documentary from BBC is very beautiful, they follow flying fishes and their predators and as you can see there is no rest for these fishes. If the fly too high they finish in a stomach of birds but if they go too deep they finish in the stomach of bigger fishes. This is really well shot and slow motion are amazing in this video, you can even watch it in HD to have better sensation.
