An anonymous reader writes Having completed his 31-day stretch underwater, Fabien Cousteau, grandson of famed oceanographer Jacques Cousteau, shows off his underwater laboratory to PBS in this video. When asked about his observations' Fabien said' "It's just amazing, we've seen so much new behavior that I've never seen before. Fish sleeping in sponges, a goliath grouper attacking a barracuda, never seen that before, I don't think anyone has ever caught it on film before. Christmas tree worms, spawning and giving off this milky smoke like stuff off. I mean it's just science fiction, it's really amazing down here. And that's why we're down here, my grandfather used to say, in order to film a fish you must become a fish. So we're trying to get as close as we can to becoming fish."
