In the blue sea and deep blue.
The giant whale was slowly falling.
Yang Xu captured this scene through the lens.
It was the first time that the audience in the live broadcast room had seen such a phenomenon in person.
And Yiying mentioned the four stages of whale landing.
It has also become a hot topic among the audience.
[I originally thought that the 'whale fall' was just a giant whale falling to the bottom of the sea after its death, but I didn't expect it to be that simple. ]
[The nature of death is not beautiful, but the process of whale landing is a contribution to the marine ecological cycle, which is undeniable. ]
[Then the question is, what do you mean by the stages of whale landing mentioned by sister Yiying? ]
Yang Xu is now under shallow water.
Although the diving depth was not deep, he couldn't communicate with the audience after he got into the water.
Yiying, who remained on the Yunfan, scratched her head.
She smiled and said, "Actually, I know a little bit, but Brother Xu told me."
Although whether it is the audience or Yiying.
When communicating.
The eyes never left the picture that Yang Xu sent back from underwater.
The huge blue whale sank slowly.
Visual pressure and impact coexist.
Occasionally, fish will flock to the carcass of a giant whale.
They are not 'escorting'.
It is absorbing the nutrients from the body of the blue whale.
at the same time. 557
This is also the first stage of "Whale Falling".
Yiying went on to say: "The four stages of whale landing,
They are "Mobile Scavenger Stage"
The 'opportunist stage'
"Chemical autotrophic stage"
And the 'reef stage'. "
Her series of answers.
Naturally, the audience was a little confused.
Maybe it suits Yang Xu for a long time together.
Yiying became more concise and concise when she spoke.
"In the first process of the fall of the giant whale, many small marine creatures will eat their carcasses."
"Blue whales weighing more than 100 tons will become a food source for small marine creatures for a long time to come."
In addition to the parasitism of some crustaceans.
Hagfish, sharks and other fish will also participate in this first whale landing stage.
These 'mobile scavengers' will feed on the soft tissues of whale carcasses.
The entire phase will last from four months to two years.
When more than 90% of the meat and soft tissues of the giant whale body are decomposed.
The first stage of the whale landing officially ended.
In the live broadcast room.
Audiences who have never understood "Whale Falling".
I was shocked by what Yiying said!
[More than 100 tons? These blue whales are too big! ]
[I think that humans have given a deeper meaning to the whale landing, but its essence is the process of being eaten away after death. ]
[It's cruel and not beautiful, but we can't seem to do much except for a'gentle interpretation' from a human perspective. ]
Although the sand sculpture netizens in the live broadcast room, they like to run the train with their mouths full.
But at this time they have some comments.
Yiying also recognized it very much.
The process of whale landing was not beautiful, and even cruel.
But except in artificial ways.
Understand it as 'giving back to the last tenderness of the sea'.
Cycle between natural ecology.
Humans are often just bystanders.
…
At this moment, Yang Xu is underwater.
An amazing move was made.
With the sinking of the huge blue whale, he was no longer able to dive with him.
The pressure in the deep ocean is rising.
Even with the ability to [deep sea sneak].
But wearing a wetsuit, he chose to float.
The only thing the audience did not expect was.
Yang Xu suddenly released the camera equipment in his hand.
Let the camera continue to follow the sinking of the giant whale…
The blue whale that is 'dying'.
Falling in the deep sea of Wang Yang…
whereabouts...
Shocked and oppressive.
Huge and lonely.
In the process of Yang Xu rising slowly.
The camera equipment fell at the same time as the giant whale.
In the live broadcast room, the audience lamented the beginning of this peculiar ecological cycle.
Giant whales are shocking existence in the ocean.
Their death.
It's also eye-catching!
[In this way, as the largest mammal in the ocean, whales can be considered alive and handsome, and deadly heroic! ]
[Sister Yiying hasn't mentioned the remaining three stages yet? ]
[When the giant whale sinks to the bottom of the sea, it will become a skeleton in two years…]
Seeing Yang Xu, Yi Ying chose to float to the surface.
Naturally, I was a little less worried.
Facing the doubts of the audience in the live broadcast room.
She went on to say:
"As for the subsequent'opportunist stage', it is the small creatures of crustaceans and polychaetes that turn the bones of giant whales into their own habitat."
"They will not only live in the bones of whales, but also clean up 10% of the meat and soft tissues left over from the first stage."
From larger fish such as hagfish.
To the smaller sea creatures.
After the death of the giant whale, it provides an ecological food chain that includes 43 kinds of creatures!
With the first and second stages of the whale landing process is over.
The anaerobic bacteria and archaea in the ocean will complete the third stage of "Whale Falling"!
These bacteria break down the lipids in the whale bones.
This produces deep-sea hydrogen sulfide.
With the continuous advancement of the whale landing process.
The object of energy supplied by the bones of the giant whale became smaller and smaller.
And the final result of "Whale Falling".
It is the last 'reef stage'!
The remaining giant whale bones cannot be completely decomposed by anaerobic bacteria.
Whale bones will eventually form minerals and turn into reefs.
And those reefs will endure on the bottom of the sea.
The final attribution of "Whale Falling".
Maybe it has witnessed the change of the sea into a sacred field.
…
Yiying scratched her head and said:
"Maybe what I said is not comprehensive. That is because Brother Xu hasn't taught enough. That's roughly what I meant anyway."
The audience in the live broadcast room, although unable to witness the four stages of the whale falling.
But with Yiying's explanation.
They can make up for the spectacular scenes at every stage.
At this time, Yang Xu has already floated back to the hydrophilic deck of the yacht.
The audience in the live broadcast room joked:
[Xu's diving skills are good, but it costs a lot of cameras. ]
[Isn't that to allow us to watch the first stage of the whale landing for a while? ]
Yang Xu took the towel from Yiying.
Wipe the wet hair clean.
"Brother Xu, I just briefly talked to the audience about the process of landing the whale, but I don't know if there was a mistake."
Yiying looked at Yang Xu east and west.
It seems to be checking whether he was injured just before diving.
Yang Xu threw the towel to Yiying, and then said plainly:
"It is precisely because of the length of the four stages of whale landing and the extensive circular ecological food chain that there is a saying that'one whale falls, all things live'."
indeed.
No matter how many stages the whale falls.
In the end, there is nothing more than 'a whale falls, everything is born'.
[Finally, whale bones turned into reefs~ Death is so vigorous, it is worthy of being the best in the ocean! ]
[The giant whale has sunk into the bottom of the sea, and the camera is probably about to stop working… It's a magnificent process! ]
Immediately afterwards.
Yang Xu instructed Yiying: "Continue sailing according to the original plan, and then stop at the islands and reefs ahead to rest."
The last light of the setting sun.
Already almost submerged in the sea level.
Both the Yunfan and Yang Xu Yiying need a little rest.
In order to continue sailing towards the subtropical waters in the south.
However...
Yang Xu changed his diving suit and took a cold shower by the way.
When he returned to the deck from the second-story cabin.
The situation on the deck stunned him…
