Leisurely Live Broadcast from Ocean Global

Yang Xu's sentence "Bernoulli's Law!

Door

It made Yi Qian and the audience in the live broadcast room extremely puzzled.

The "sail jellyfish" in those pictures

0

About five to fifteen centimeters in diameter.

The transparent "sails" erected on the body are like crystals.

A sea breeze blew.

Or a burst of waves.

will make them float a long distance.

They don't swim like normal jellyfish, they can only migrate and move with wind and waves.

The "sail jellyfish" on the sea is like a miniature fleet of creatures~

"Brother Xu, you are going too far. How can the body structure of this jellyfish be related to the laws of science?"

Yi scratched his head and asked.

Her remarks can be regarded as the voice of the audience in the live broadcast room.

【Sister Ying is right, do these cute little jellyfish still understand science?”

"It's really too much. Brother Xu is in and out of my knowledge blind spot, which makes me feel so uneducated~QAQ~)

[The small book is ready, ready to record today's little knowledge point VI

at the same time.

Yang Xu did not directly answer the question about Bernoulli's law.

Instead, I went to the hydrophilic deck, intending to say hello to those sail jellyfish!

0

The little silly dog ​​Nennen followed closely, and seemed to want to go to the uninhabited island to play.

"I'm going to see those sail jellyfish up close." Yi Qian said with great interest.

After all, it was the first time she and the 13 viewers in the live broadcast room saw this thing.

But fresh is rare.

wow~

The night wind blew softly.

After leaving cold Alaska.

The temperature of the sea is rising.

There was even a warm air in the wind.

Compared to the cold wind like a knife.

The warm sea breeze is more comfortable.

Follow the Yunfan number all the way south.

Yang Xu and Yi Qian will re-cross the 'International Date Line'

0

When traveling to the Bering Sea.

They "travel" from today back to yesterday.

In the next voyage, except from today to tomorrow.

They will also move from autumn and winter into spring and summer.

It's not just sea voyages from north to south.

At the same time, it is also a strange journey through the seasons~

"Can't these little jellyfish swim by themselves? All rely on waves?" Yi Qian and Yang Xu got off the yacht.

The nights on the uninhabited reefs are extraordinarily peaceful.

Yang Xu zoomed in and captured the small sail of the sail jellyfish more clearly.

"They don't rely entirely on the waves, but also on the sea breeze. Do you think these 'sails' are decorations?"

The audience in the live broadcast room talked a lot:

[I understand, these "sail jellyfish" use their bodies to set up small sails~ relying on the wind and waves to drift on the sea to hunt for food.

[Really. The world is home, where the waves go, where do I go~)

[I just did a search by Du Niang, Bernoulli's law is the equation of fluid dynamics! For example, the scientific formula of the potential energy and kinetic energy of airflow and water flow! 】

[So they have a special "scientific way of sailing"? So interesting!)

Yang Xu crouched down.

Pick up a small sail jellyfish.

He went on to say:

They "also have buoyancy sacs like the man's jellyfish, made of hard chitin, but the ones we encountered were larger than the usual sail jellyfish.

Yi Qian supported her legs and squatted beside Yang Xu.

"Is that the venom gland in the transparent body? But it's not very lethal, it can't pierce the skin of the human body, right?"

She added: "That being said, these sail jellyfish are somewhat similar to the man's jellyfish."

Yang Xu nodded and said: "In their stomachs, there are radial pipe networks that capture some plankton and algae life.

True.

The sail jellyfish is the strangest.

It is above the blue-purple floating sac, erected a nearly transparent triangular "sailboard"

this body structure.

Help them travel across the ocean, propelled by the wind and waves.

Yang Xu then used the lens.

To those little sails of the sail jellyfish, here comes a close-up.

He continued: "The 'surfboard' on these little jellyfish is inclined at a 45-degree angle to the plane of the body, and anyone who has played sailboats should know that this is a very delicate angle."

The sail jellyfish's "sail" is not upright.

The inclination formed is very similar to that of a sailor grasping a sail.

"If according to Bernoulli's law, the human sailboat can travel at the maximum speed at this angle under limited wind conditions!

Yi Ying was taken aback for a moment.

The audience even sighed at the magic of the evolution of nature's creations!

"In the process of natural evolution, they have mastered the dynamics researched by scientists! So those "small sails" are efficient physiological structures for sea navigation!

Yi Qian added incredulously:

"The evolution of these little sea creatures is really amazing!"

After such an explanation by Yang Xu.

The audience in the live broadcast room woke up:

[It turns out that this is why Brother Xu mentioned "Bernoulli's Law" before~ These sail jellyfish are so powerful."

[That's not true, relying on the body structure of hydrodynamics, everyone is a little expert at sea navigation! 】

"Sail jellyfish inner OS: no one knows the wind and waves better than me~)

"So can they reorient at any time? Wouldn't that be passive?

Ida tilted her neck, watching the little sail jellyfish.

Their construction is complex, yet simple at the same time.

No ability to actively swim.

They can only really go with the flow~

Yang Xu shrugged and said, "If it really washed up on the shore, it would only be stranded and become food for other animals."99

Nature is like that.

The ecological cycle is like a nesting doll, I eat you, it eats me...

As Yang Xu said.

With the waves crashing against the reef.

Many "sail jellyfish" drifted ashore and washed ashore.

Meow claws take those stranded sail jellyfish.

One by one, they were pulled back into the sea.

But then came the next wave.

Those sail jellyfish will run aground again.

But Nennen was so anxious that she screamed and turned in circles.

Yang Xu and Yi Qian looked at each other...

I didn't expect this dog to be so loving.

Yang Xu patted the tender dog's head and said:

"Don't waste your time, you, a little wolf dog, can't save thousands of sail jellyfish."

Although a lot of cute sail jellyfish.

Stranded on an uninhabited reef island in the wind and waves.

It made Yi Qian a little surprised, but she was relieved.

She 883 said to the audience in the live broadcast room: "These small marine life have mastered the scientific body structure in the wonderful process of evolution, but the cycle of the ecological circle, like the "whale fall", is part of the ocean . "

and.

still an integral part.

The night is getting darker.

The sail jellyfish on the uninhabited reef is an unexpected encounter between Yang Xu and Yi Qian.

More sail jellyfish, after the wind has changed.

Raised their 'little sails'.

Continue to cross the ocean~

"Can we have some of these 'sail jellyfish'? Don't we have an aquarium?

Yi Qian was talking.

He hugged the little silly dog ​​Shisou who was trying to die in the water.

Yang Xu shook his head and did not speak.

Although these sail jellyfish are special, they are also cute.

But with Yang Xu's character.

Your own aquarium, if you want to keep it, you need to keep something more special!

Immediately after.

Yang Xu narrowed his eyes slightly.

It's like finding something in the shallow sea.

He threw the fishing rod in his hand to Yi Qian.

Walk alone towards the shallow sea area.

"Do you still want to fish, I'm going back to the yacht to cook.

Yi Qian rubbed her belly.

Really hungry.

Yang Xu didn't even say, "I found something good to add to my meal!"

"What good stuff? Is it delicious?" Yi Qian asked curiously.

The audience was also very puzzled.

Brother Xu, what did you find again?

(Seeking monthly ticket QAQ~).
