The ship was sailing very fast, and Su Ran seemed to have discovered some clues on the sea.

"Look, there, it seems like there's a horn sticking out!"

Su Ran clearly saw a unicorn horn appearing on the calm sea surface.

That's clearly a narwhal!

"I found a narwhal!"

Su Ran was overjoyed. He immediately controlled the drone to fly in the direction of the narwhal.

As the drone got closer, a huge narwhal appeared in his sight in the bird's-eye view.

This narwhal is huge and magnificent, and its long horn is like the horn of the legendary unicorn.

When the drone got closer, Su Ran could clearly see that its smooth skin was covered with some fine textures, as if it was a unique mark given to it by nature.

The narwhal's body is a deep blue color that contrasts sharply with the surrounding water.

Its back is bulging like a small hill, giving people a sense of powerful strength.

As the drone continued to fly forward, Su Ran noticed that the narwhal's tail was swaying in the water, and it seemed to be swimming gracefully.

"Is this the narwhal? I didn't expect there are such creatures in the ocean."

"Oh my god, I wonder if unicorns are based on that."

"This is the second creature that I know of that has horns, besides rhinos."

"It looks like this is the first time for everyone to see this."

"This opportunity can only be had in Su Shen's live studio."

Deng Jiaying was also very excited when he discovered the narwhal.

He really didn't expect Su Ran to be so lucky that he could get something on his first trip to the sea.

As the drone continued to fly forward, Su Ran discovered that there was a group of small fish surrounding the narwhal.

They don't seem to be afraid of this huge creature, but instead live in harmony with it.

"It seems that most marine life is relatively harmonious. Now that we have found the narwhal, we just need to collect a few more samples and we can go back."

After completing the task assigned by Deng Jiaying, Su Ran had nothing else to do.

Before leaving, he opened the trawl directly.

With such a large fishing boat, the catch is naturally very large.

When Su Ran was returning and about to dock, he suddenly saw a stranded whale on the coast.

His brows furrowed. “Look, that’s a whale. It seems to be stranded.”

Su Ran's face did not look good, and the audience also noticed this.

"Brother Su, did something bad happen to you?"

It’s hard to say it’s bad, but Su Ran is now feeling a little worried.

He steered the fishing boat and started to leave the port.

This left the audience very confused.

"You were clearly preparing to go ashore, why are you suddenly going back now?"

"Brother Su, aren't you going ashore?"

It’s not that Su Ran didn’t want to go ashore, but that he didn’t dare.

"Do you know that there are two situations when a whale dies?" Su Ran's expression was serious.

The first one he mentioned was whale fall.

As the saying goes, when a giant whale falls, all things come to life!
Simply put, whale fall is the process of a whale slowly sinking to the bottom of the sea after death.

Although this phenomenon seems common, it is not easy for a creature to sink to the bottom of the water after death.

In nature, the phenomenon of dead animals floating in water is a fascinating topic.

Take pigs for example. When they drown, their bodies are usually found floating on the surface of the water.

This situation is not unique to pigs. Even the huge hippopotamus will float upside down after death.

Behind this phenomenon lie the mysteries of biology and physics.

The floating of animal carcasses in water is closely related to the decay process.

When an animal dies, the microorganisms inside its body become active, decomposing the organic matter in the corpse and producing large amounts of gas.

These gases mainly include methane, hydrogen sulfide, ammonia, etc., which accumulate inside the corpse, causing the corpse to gradually swell.

As the gas continues to be produced, the air pressure inside the body gradually increases. When the air pressure reaches a certain level, the body will be filled up like a balloon, thus generating buoyancy.

This buoyancy is enough to offset the body's weight in the water, causing it to float on the surface.

This is why it is common to see the bodies of drowned pigs or hippos floating on the water.

According to the above statement, the animal's body will float to the surface after it begins to rot in the water. Strictly speaking, all whales that die of natural causes may form a whale fall.

However, not all whales that die naturally form whale falls.

Because the conditions for the formation of whale falls are relatively harsh.

There are nearly 100 different species of animals in the entire order of whales. After their death, the smaller whales are mostly eaten directly by other carnivores, so naturally no whale fall can form.

Large whales do not necessarily form whale falls because once the density of the whale is less than the density of seawater, it is difficult for it to sink. For example, blubber is a substance with a lower density than seawater.

If a whale has too much blubber, it will be difficult for it to sink after death, such as the right whale, which has a thick layer of fat all over its body.

Therefore, as long as a whale is large enough, its body will not be eaten quickly after it dies. Moreover, after the whale dies, the blubber of whales with less blubber will be slowly decomposed over time.

What is left is whale meat, which is denser than seawater. In addition, as the whale's carcass floats, seawater will enter its abdominal cavity, which makes it easy for a whale fall to form.

Su Ran described two situations to the audience.

The first situation is relatively peaceful, while the second is full of danger and uncertainty.

In the second case, the whales' death process is not peaceful. Their bodies will slowly sink to the bottom of the sea and become food and home for deep-sea creatures.

However, for those whales that unfortunately become sick or die, their fate is even more tragic.

They may drift with the current, be swept ashore by the tide and become stranded on the beach. Stranded whales have little chance of survival because they need to consume food equivalent to 2-10% of their body weight to survive.

The whales seen now are undoubtedly dead, and may even be dead.

Therefore, even if there were people in the live broadcast room asking Su Ran for help, he basically ignored them all.

Su Ran told everyone that the reason he wanted to leave the boat was because the whale on the shore was likely to explode.

He could conclude that the gas in the whale's body was accumulating more and more, like an inflated balloon that could explode at any time.

The marine zoology expert in the live broadcast room also confirmed this.

"Whales eat a lot before they die, and their skin is usually very thick and durable. The gas produced slowly accumulates in the body and is compressed until it can no longer be contained and explodes." (End of this chapter)
