In 1984, a very strange thing happened in the United States.
Floating residents living in Francisco Bay are kept awake every night by an ear-shaking buzzing sound.
At first, locals thought it was the sound of a pump or underwater generator.
As a result, when the locals raised money to hire people to go underwater to take a look, they did not see any pumps or underwater generators at all. Moreover, as soon as someone went underwater, the annoying buzzing sound immediately disappeared, but as soon as the person came up, the sound would immediately start again.
That's better.
Haunted Thresh.
There is nothing more to say.
Even if the king of heaven comes, there will be ghosts.
Locals moved away overnight and fled the town.
In fact, the buzzing sound is made by a kind of fish.
In 1991, the incident continued to ferment and became more and more serious.
The United States was forced to send troops and scientific research teams to investigate and confirm.
When the investigation results came out, the military’s popularity was ruined.
It turned out that the sound was made by a local fish living on the seabed, which was vigorously flapping its swim bladder as a way of courting.
Coincidentally, in a shallow bay in Sri Lanka, when night falls and everything is quiet, tourists can often clearly hear beautiful sounds coming from the bottom of the water, just like the sound of the organ described in ancient Greek mythology. In fact, it is also the fish singing.
The only difference from Francisco Bay is that the locals in Sri Lanka did not regard this sound as a supernatural event, but adapted to local conditions and vigorously developed the tourism industry. Now Sri Lanka's Repulse Bay is a very popular tourist destination.
Xiang Yang put on his diving suit again and said, "You guys wait on the boat. I'll go down and see what kind of fish is making such a loud noise. It's making the noise under the sea, and my ears are vibrating even when I'm on the surface of the water."
Chen Qingsheng was shocked by Xiang Yang's words, "No, Captain, please don't do that."
"Think positively!" Zhang Qicheng also grabbed Xiang Yang's arm. "If someone can make such a loud noise, you can imagine how big the other person is, right? If you go down here, there is an 80% chance, no, 100% chance that you won't be able to come up."
"I think it's a sea monster." Fang Youqun said with a smile.
Xiang Yang smiled as he put on his diving suit, "Fish have many organs, including upper and lower jaws, throat teeth, fins, swim bladders, and air sacs. The sound-making mechanism of fish can be divided into rubbing sounds, swim bladder sounds, and inhalation and exhaust sounds. The sounds made by these are very loud. Just like frogs and cicadas, small creatures that are no bigger than a palm, the sounds they make can be heard a mile away."
"I also guess that the fish making the sound below is not big." Xia Pengjie said.
"What's the basis?" Xiang Yang asked him.
Xia Pengjie pointed at the killer whale playing behind the boat and said, "Because that guy must not have any fear at all."
Xiang Yang smiled and nodded, but he was slightly disappointed in his heart. He thought Xia Pengjie was relying on knowledge.
But it is also very good to know how to observe carefully.
Frictional vocalization refers to the sound produced by fish by rubbing the hard parts of their bodies against each other, such as the throat, teeth, gill covers, and fins.
Swim bladder vocalization refers to the fact that fish make sounds by vibrating their swim bladder.
The sound of inhaling and exhaling air is produced by some fish through the sucking action. A small number of fish can make a loud noise at the moment of swallowing sea water.
The fish's genetic system and mechanism are slowly formed in the long-term natural selection process. Some fish use sound to gather groups, transmit information, seek help, courtship, etc.
Some fish also use sound waves to detect their location and find food.
Some fish, such as killer whales, use sound to scare off their enemies.
Xiang Yang briefly introduced the sounds made by some fish to the crew, and then said: "In the early 19th century, geographer Alexander Humboldt wrote that on the night of February 20, 1803, all the crew were frightened by an extremely strange sound, which sounded like the sound of drums in the open air... That was the first recorded sound heard by humans from fish. In fact, what they heard was the sound made by a fish called a drum fish."
Xiang Yang jumped into the sea.
The killer whale swam over immediately, turned its big head towards Xiang Yang, and its eyes rolled around.
Xiang Yang patted the killer whale's head, then swam underwater and turned back to signal the killer whale to follow him.
soon.
Xiang Yang went down to the bottom of the sea and found the creature that could make sounds in a very dense seaweed patch.
right.
Strange fish.
A very strange fish.
Xiang Yang tried every word in his mind, but couldn't find one to perfectly describe the strange fish.
The fish was not big, about 30 centimeters long, but its body was very wide, almost two-thirds of its length, and it looked particularly fat, just like the fat silver carp in the cartoon The Adventures of Little Carp.
What’s interesting is that the fish’s forehead and body are covered with stripes. The base color is sky blue, but the patterns are an indescribable color. There are black patterns, dark blue patterns, and sky blue patterns that are lighter than the base color.
Its lips were very thick and its mouth was very wide. Its two eyes were symmetrically located above its mouth, staring at Xiang Yang without blinking. To be precise, it was staring at the killer whale behind Xiang Yang. Its mouth was slightly open, revealing two snow-white little fangs, and its body was trembling.
Xiang Yang raised his eyebrows. "This fish should also be called a sea toad, right? Was it the one that made the deafening sound just now?"
Xiang Yang swam towards the fish.
The fish didn't even look at Xiang Yang. It continued to stare at the killer whale without blinking. It closed its mouth and its body trembled even more violently.
Xiang Yang stretched out his hand and caught the sea toad.
"They are both called toadfish, but this sea toad is much better looking than that stonefish." Xiang Yang teased the sky blue sea toad with a smile. The sea toad raised its head, and its two little eyes looked at Xiang Yang eagerly, looking so cute and adorable.
Xiang Yang looked at the fish carefully and found a row of sky blue whiskers under its mouth.
The sea toad's whiskers are as strange as its appearance.
Its whiskers are very long, each one is about two or three centimeters long.
Moreover, each of its whiskers is very thick and fleshy.
The strangest thing is that the shapes of its beards are different. Some are normal beards with a wide base and a pointed top, while some have a lot of branches in the middle, as if a row of Christmas trees were planted on the chin.
"What a strange fish. Bring it up and show it to everyone." Xiang Yang smiled and put the sea toad into the net bag, then swam towards the surface of the sea.
