Ocean Hum secret signal that migration, or fish Farting
#Cosmoread: Large communities of deep-sea marine life in the ocean getaway mysterious, low-frequency humming sound, as creatures and swim to the surface to feed on them are the perpetrators behind made.
Search, California, San Diego Simeone Baumann- Pickering assistant research biologist, conducted by the University for a long time to answer the question. For years the source of the hum, sea creatures vexed because NPR reports. They knew the sound transmission, such as dolphins or other marine mammals did not conform to the whale calls.
Now, thanks to the high sensitivity down to the audio recording, Baumann- Pickering says that this kind of fish, jelly, shrimp, and squid living in what is known as ocean mesopelagic zone as animals – down 200 1000 meter range (660 3300 ft) surface – that are behind the sound.
Mesopelagic neighborhood creatures live deep down, a dark world where the sun rarely shines and there really is not in the food reward. So every night, with the safety of darkness, they venture to the surface where food is more plentiful.
And when they head up to the top (or bottom back) hum – the kicks – the ocean about 3 to 6 decibels louder than the background noise.
“It is not loud,” Baumann- Pickering said in a statement. “It sounds like a buzzing or humming, and that goes on for an hour to two hours, the day depends on.”
The purpose behind the sound is still an open question. Pickering said it Baumann- a signal to the whole group or back up to the surface and down to the head can be.
However, it seems that this may be happening is clear communication between animals, there is also a less high-minded may cause harm. It turns out that life is just passing gas as their swim bladder may regulate their buoyancy.
“It is known that some fish farting, considered” Baumann- Pickering told NPR, “that they emit gas depth in the water column as they change.”
Mesopelagic’s Denizens engage in any such communication, then learn more about the messages being given and what are the messages of specific animals would help scientists a better understanding of the ecosystem they inhabit come Baumann- according to Pickering.
Also mesopelagic predators that feed on animals may tell researchers more about – listening to the hunters, we could tip them off food is nearby.
