Fish farts caught on microphone

Okay yeah. So I wanted to post a thread in the science forum about fish farting noises. Who wouldn't?

You might expect the middle of the Pacific Ocean to be a pretty quiet place, especially a thousand feet down. But it turns out that huge parts of the ocean are humming. Scientists have puzzled over the source of the sound for several years. Now, a marine biologist reporting Monday at a meeting of ocean scientists in New Orleans says she thinks her team may have figured it out.

But there's another more mundane possibility. "It's known that some fish are considered to be farting," says Baumann-Pickering, "that they emit gas as they change depths in the water column." The gas comes from a swim bladder inside the fish that controls its buoyancy. In either case, billions of fish may be jetting up and down in the ocean every day, and making it hum. If so, it would likely be the largest migration of vertebrate animals on the planet, Baumann-Pickering says. She calculates that the weight of the fish amounts to some 10 billion tons.
