Liu Wei: "Not all whales will sink to the bottom of the sea to form whale falls after they die, some will be pushed to the shore by the sea water and run aground to die, and some whales will take the initiative to pounce on the shore and commit suicide!"

"Suicide?"

"Did I hear me wrong? Whales kill themselves!"

"First time I've heard of it!"

"There are times when whales can't think about it!"

"Why?"

The audience in the live broadcast room was collectively confused.

Very curious about the claim that whales "commit suicide".

Liu Wei originally thought that many viewers should have understood this situation, after all, there are many reported whale suicides in the world, and it can even be said that it is about to become a commonplace phenomenon.

Whale suicide is not just seen in individuals, many times it is a group suicide.

Liu Wei said: "Marine biologists have put forward many hypotheses about the phenomenon of whale suicide, such as topography, aberration, guidance, atavism, etiology, feeding, and so on.

These assertions are based on research into the anatomy and lifestyle of whales.

And one of the objective causes of whale suicide that I would like to mention is marine pollution.

From the beginning of the century to the present, whale suicides have been found in the low-coast areas of many coastal countries, including our country.

Scientists discovered the same phenomenon when dissecting whale carcasses, which were filled with indigestible plastic waste.

Once on the southwest coast of Norway, someone witnessed a whale suicide, a 20-ton sperm whale.

It repeatedly slapped against the shallows, looking very uncomfortable, as if only stranded death could end its suffering.

Later, scientists dissected the sperm whale and found that its stomach was filled with more than 30 plastic pockets, which could not be digested, and the penetration of chemical components caused the sperm whale's stomach to be severely informed.

I can't vomit, I can't eat, it's very uncomfortable, you can imagine it!"

"It's so uncomfortable!

"I want to cry!"

"Hey, I don't know what to say!"

"Can I say sorry for humanity?"

"To be honest, in reality, there is no existential conflict between sea creatures and us!"

All kinds of barrages of righteous indignation and guilt in the live broadcast room were brushed up.

Liu Wei's feelings are the same as the audience's, "I hope there will be less and less news like this!"

After adjusting his mood, he swam to the belly of the whale, and there were still a few fish and crabs eating away at the remaining soft tissues, but the internal organs had been hollowed out.

Liu Wei filmed: "I just mentioned the matter of the Japanese scientists artificially creating whale falls, which is a huge systematic scientific experiment.

Often, stranded whale carcasses are used for scientific research or taxidermy.

The handling of whale carcasses needs to be very careful, as there is a high chance of causing a whale explosion!"

Another word that the audience has not heard of.

The question mark barrage immediately covered the live broadcast screen.

Liu Wei explained: "As the name suggests, a whale explosion is the possibility of an explosion of a whale's carcass.

After the whale dies, the internal organs and tissues will decay, the bacteria will spread, and the proteins in the body will be broken down, producing methane, ammonia, hydride and other gases.

These gases cause the whale's carcass to expand rapidly, threatening to explode at any moment.

If the operator does not handle it properly, he will directly take the knife to dissect the whale carcass, and when the knife cuts an opening on the whale carcass, the gas in the body will be discharged at one time, and the organs that have not yet decayed will also explode. ”

"Hey~, there's a picture!"

"Damn, the movie scene is here!"

"It's disgusting!"

"Entrails are flying all over the sky!"

"Don't say it, I'm eating!"

"Hahaha!"

Liu Wei: "The gas discharged from the corpse is very toxic, which can harm the human body and many organisms, and may even poison people to death.

Of course, people with sensitive breathing can also stink to death from the smell of the explosion.

Therefore, if you want to make a whole whale carcass into a complete specimen, you will usually bury it in the ground for a few years and wait for the gas in the body to dissipate before proceeding to the next process.

In 04, there was a whale explosion incident in Wanwan, which was a sperm whale weighing 50 tons, and the experts in Wanwan wanted to make it directly into a whale specimen, and called a tow truck to drag the body back, just when it was dragged to the city center, the whale carcass suddenly exploded, and the entire city center was shrouded in blood mist, and many people were admitted to the hospital, and the stench produced after the explosion lasted for several months before dissipating!

"Poof~ Laughing!"

"The experts at Wanwan are so cute!"

"Hahaha, I'm sick of it!Do you know that people are most afraid of smelling the smell!Hmph~"

"Laughing and crying, the talent upstairs, it's exactly the same!"

Liu Wei looked at these actors in the live broadcast room, and couldn't help laughing.

He turned on the system ventilator and adjusted his breathing.

He was in a position where he could barely receive sunlight anymore, and the water around him was very smooth, although he was in the middle of a wide sea, which made him feel like he was in a claustrophobic space.

There is no sunlight, no plants can photosynthesize, no hot and cold water flows, and no geothermal heat generated by submarine volcanoes, making the seabed environment very poor.

In this case, the nutrients and energy brought by the more than 10-meter-long sperm whale carcass in front of you are particularly important to the biome that "survives" on the barren seabed.

It can be said that the effect of a sunken whale carcass on the bottom of the sea is the same effect of a fully loaded oil depot on the icebreaker "Dream"!

After Liu Wei breathed, he continued, "At the beginning, we mentioned the first process in the evolution of whale falls, the mobile scavenger stage.

Let's move on to the second stage, the opportunist stage.

At this time, the whale carcass has only a small amount of soft tissue and a large skeleton, and some invertebrates and crustaceans will move to live there for a long time.

For example: the bone-eating worms, an ancient sea creature that lives by eating bones, burrow into whales' bones and rely on symbiotic bacteria to break down and absorb bone oil and nutrients!"

"Bone-eating worms, the name sounds like something inside a tomb!"

"I feel the same way!"

"I've already remembered the worms in the ghost blowing the lamp and the tomb robbery notes!"

"It's terrifying!"

"Drilling holes in bones? Dense phobia collapsed!"

The audience reacted strongly.

Liu Wei said: "These creatures gnaw on the residue while reproducing offspring, and they will not leave until the last trace of flesh has been eaten away. This process usually lasts about two years!

After the end of this stage, the whale fall enters the third evolutionary stage, the chemoautotrophic stage, which is also the most important stage of the whale fall evolution.

When only the skeleton of the whale remains, the whale fall is truly revealed as a unique survival system in the deep sea.

A large number of anaerobic bacteria will enter the whale bone and other tissues left in droves, break down the lipids in it, and use the sulfate dissolved in the sea as an oxidizing agent to produce hydrogen sulfide, which is a toxic gas, but for many deep-sea biomes, it is the sunlight on the ocean floor!"
