Li Gesheng found Xiang Yang's serious expression a little funny. She covered her mouth and laughed, "Can octopuses also use tools?"
"Yes, that's right. The octopus is a very capable animal. It can use tools ingeniously, such as moving rocks."
Stones are very versatile for octopuses.
Octopuses know how to use stones to build houses. When they have nowhere to hide, they will build their own houses. They pile stones, shells and crab shells together to build a nest similar to a volcanic crater, and then hide in it so that no one can find it.
In addition, stones are also the octopus's weapons of attack and self-defense.
When fighting with its natural enemies, an octopus often grabs two stones that are half the size of its head. One is the octopus's weapon of attack, and the octopus will use its tentacles to wrap the stone and smash it hard at the opponent. The other is the octopus's weapon of self-defense. When fighting with other ferocious marine predators, it will use a large stone as a shield in front of its head. No matter from which direction the opponent attacks, it must first attack the stone it is wrapping before attacking its head.
When the octopus cannot defeat its opponent and needs to retreat, it will use stones to block its retreat.
"Octopuses can build houses? Brother Xiang, you are not talking nonsense, right? Why have I never heard of this?" Li Chao looked at Xiang Yang suspiciously.
Zhang Qicheng also frowned. "I do know that octopuses, like squids, like to hide in bottles and jars, or in sealed places like shipwrecks. I don't know how to build houses."
Many animals have the habit of building nests.
The most famous are birds, such as swallows. The bird’s nests built by swallows are also a very precious food ingredient.
However, those are all land creatures, and there are very few marine creatures that can build nests.
"Yes, octopuses can build houses, and it is a very interesting thing to see octopuses building houses." Xiang Yang said with a smile.
Octopus is one of the most common creatures in the ocean. Xiang Yang had studied it in school, so he knew a lot about it. He also knew a little about many interesting things that have no practical use but do exist.
"Every time an octopus builds a nest, it does so at night. Before midnight, no sound can be heard. After midnight, as if receiving an order, the octopus will quickly use its eight legs to crawl on the seabed, collecting stones that it can carry, and then move all the stones together to build a stone house that it can move into."
In 2009, scientists discovered an "octopus city" at a depth of 10-15 meters in Jervis Bay, eastern Australia.
The layout of that octopus city is similar to that of cities inhabited by humans. The houses are arranged in an orderly manner, and there are standard intervals between the houses, just like the convenient and developed transportation in a city.
At first, scientists thought they had discovered an alien civilization and were very excited.
But later through research and investigation, it was found that it was actually a gathering place for a group of octopuses.
The octopus city is made up of a series of stone nests, with unique architecture and perfect layout.
Those stone nests are mostly made of food scraps, glass bottles and fish bait.
Scientists speculate that the octopuses extended their tentacles from the stone nest and gathered the surrounding rubble to reinforce their nests, but because the Octopus City was formed too long ago, researchers have no way of knowing its real secret.
Scholars published a report about Octopus City in the journal "Marine Freshwater Behavior and Physiology". The report said: Octopus City does exist, but it is more like a college dormitory than a city. In Octopus City, octopuses will cooperate with each other and send signals, protect their partners, male octopuses will chase each other, change roommates, and even ignore unwelcome companions.
The discovery of Octopus City broke people’s inherent perception of octopuses.
Before 2009, scientists defined octopuses as solitary and loners. Marine biologists believed that octopuses were moody and desired to live alone, and were not interested in so-called companions or partners. After laying eggs, female octopuses would leave once the larvae hatched.
After Xiang Yang finished speaking, he found that Li Chao, Zhang Qicheng, and Li Gesheng were all looking at him with a confused look on their faces.
Xiang Yang suddenly burst out laughing, "Why are you all looking at me like that?"
Li Chao laughed and joked, "Brother Xiang, I didn't expect you to have a talent for storytelling."
Xiang Yang: “…”
Xiang Yang told it as a story, and Li Chao and others listened to it as a story, but they didn't know that what Xiang Yang said was actually true.
Seeing that Li Chao and Zhang Qicheng didn't believe him, Xiang Yang didn't explain much, "Come, cut open this bamboo saury, and let's grill it first."
Li Chao and his friends didn't take it seriously, but some people did.
He is a visitor in Li Gesheng’s live broadcast room.
"Ge Sheng, I just checked online, and what that guy said seems to be true."
One stone caused a thousand ripples, and the live broadcast room immediately exploded.
"What's true?"
"Octopus City? Don't be ridiculous. Even science fiction movies don't dare to film it like this. How can such a thing be true?"
"If it's true, I'll turn on the 15th setting of the electric fan during the live broadcast."
There was a lot of doubt in the live broadcast room.
Seeing that no one believed him, the man angrily asked, "Is it true that you can't check it online?"
Then... ...
"Fuck!"
"My eyes!"
"There really is an Octopus City in this world!"
"How is it possible? How come I have no impression of such explosive news?"
The live broadcast room exploded instantly, with dozens of people commenting in the comments to give the impression that hundreds or thousands of people were watching the live broadcast. The popularity of Li Gesheng's live broadcast room also instantly moved up several industry rankings, with more than a dozen visitors pouring in at once.
Li Gesheng looked at the comments, then looked at Xiang Yang who was standing in front of the grill and grilling, "Brother Yang."
"Hmm?" Xiang Yang looked at her.
"Is what you just said true?" Li Gesheng asked.
Xiang Yang smiled, "I never tell lies."
Li Chao, Zhang Qicheng and others were confused. "What's true or false? What do you mean by never telling lies?"
"Octopus City!" Li Gesheng handed the phone to Li Chao and followed everyone else's example of calling Li Chao "Brother Chao". "Brother Chao, look, my friends in the live broadcast room just checked online and found that there really is an Octopus City in the world."
Li Chao insisted, "This is impossible."
"Looked it up on the Internet? Which Internet? Let me check it too." Zhang Qicheng took out his mobile phone and typed in the three words "Octopus City".
Then, he read out the words one by one: "In 2009, people discovered an octopus city on the coast of Australia. On September 27, 2017, scientists found another octopus city at a depth of 10-15 meters in nearby waters."
