The scene of seeing whales in such a deep sea really made Su Ran extremely excited.

"I think it will be hard to encounter such a scene again in this life."

Su Ran was stunned. He didn't even have time to react and record this scene.

The body of this blue whale is so huge that it is almost impossible to describe in words. When its huge body swims in the sea, it is like a moving island, giving people an extremely shocking feeling.

At this time, Su Ran suddenly reacted and prepared to take out the camera to shoot.

And when observed at such a close distance, the blue whale's skin appears a deep blue, gleaming with the light of the ocean.

It was as if an endless blue sky merged into the sea.

Its back is wide and flat, like a vast deck, making people want to step on it and explore the unknown world.
When a blue whale dives into the water, its body seems to merge with the surrounding sea water and become part of the ocean.

The appearance of the blue whale makes the entire sea surface come alive. The waves gently hit its body, making soft sounds, as if it is a symphony played by nature for this giant beast.

The seabirds circling in the air seemed to be attracted by this spectacular scene. Their cheerful chirping sounds added a touch of vitality to the sea.

Su Ran stared at the blue whale intently, and his heart was deeply shocked. He had never seen such a huge and beautiful creature, and its existence made him have a deeper understanding of the power of nature and the miracle of life.

Every movement of the blue whale showed its strength and grace. The sound of its breathing was like a gentle breeze, blowing on Su Ran's face, making him feel close to nature.

"Look," Su Ran pointed suddenly, "Look, the surface of the blue whale is mostly gray and blue, with tiny light blue stripes on its back. There are white spots on its chest, and more than 20 folds."

"Its abdomen is also covered with wrinkles that extend all the way to the navel and have yellow spots, and there is a white callus on its upper jaw where hair once grew."

"But later it degenerated, leaving behind a wart-like growth that became a breeding ground for parasites. But the shape of this callus is different in each individual, so each blue whale can be distinguished by it."

The blue whale dived into the water the next second, seeming to be somewhat resisting the camera.

Su Ran smiled cheerfully and said, "It must be shy and hiding. Let's ignore it and continue moving forward."

The fishing boat continued to sail, and during the voyage, Su Ran was also discussing the narwhal with the audience.

"Well, let me show you a picture."

Su Ran searched the Internet and found a picture of a narwhal.

He looked closely at the picture and discovered that the narwhal had a relatively short forehead and mouth, and no dorsal fin.

The narwhal is a mysterious creature that lives in the deep sea. Its appearance is similar to that of the beluga whale, but its most striking feature is the long horns on its head.

This long horn is the unique mark of the narwhal, and it is also the difference between them and other cetaceans. The horn of the narwhal is usually curved and sometimes can even stretch to about half of the body length.

This horn not only makes the narwhal look more unique, but it may also play an important role in their living habits.

If it weren't for the narwhal's distinctive long horn, it would be almost indistinguishable in appearance from the beluga whale.

"That's not right, Brother Su, why are the colors of these whales different?" The audience noticed that the colors of the whales in these pictures were very different.

Su Ran didn't think there was anything strange about it: "The color of narwhals changes throughout their lives. When they are born, they are gray or gray-brown." "After they are two years old, more white spots appear on their bodies, and the gray areas become darker."

"Adult narwhals have white bellies and black and white stripes on their backs. As they age, the black areas on their bodies become less and less, and some narwhals are even completely white."

The long horn of the narwhal always reminds people of the legendary unicorn.

But their horns are not actually horns, but the long fangs of narwhals.

The canines on their left sides extended beyond their lips, forming an elongated spiral.

The spiral tusks grow as the narwhal grows and can reach 1.5 to 3.1 meters in length.

The tusked narwhals are mainly males, but some females also have tusks.

Some narwhals have more than just one horn. The fangs on both sides of their bodies protrude from their lips and become long tusks.

However, narwhals with two horns are very rare, and there may be only one male narwhal with two horns in 500.

So if you can really meet a narwhal with two horns, you are really very lucky.

"But I understand all of this. The only thing I don't understand is, what is the use of a whale having a horn?"

"Yeah, I don't know either. Does anyone know?"

"It's hard to say, maybe he's just pretending."

"I remember reading somewhere that some people thought that the tusks were used to chisel through the ice. But the truth is, they rammed the ice with their heads, not with their tusks."

"In fact, scientists have previously observed narwhals using their tusks to knock codfish unconscious and then catching them."

"Others have linked tusks to the attractiveness of male narwhals, believing that large, powerful tusks are more likely to win the hearts of female narwhals."

Su Ran smiled and said, "In fact, the view that scientists now agree on is that the tusks of narwhals can help them sense the surrounding environment and understand how hot and salty the water is."

Another comment in the live broadcast room said: "Let me tell you, growing teeth can help narwhals catch the fish they love to eat."

Su Ran nodded: "Yes, you are right."

"And the horn on the narwhal's head is actually a tooth. This tooth begins in the embryonic development stage, with a total of 16 teeth, but at birth, most of the teeth will degenerate and disappear, leaving only two in the upper jaw."

"Among them, the female whale's teeth are hidden in the upper jaw throughout life and are not exposed, while the male whale's left tooth will break through the upper lip and protrude forward, with a length of up to 2-3 meters. This feature makes the narwhal look like it has a horn."

"This horn is not only a feature of its appearance, but also has some functions, such as helping the narwhals dig mud and sand on the seabed to find food, or as a weapon of defense and attack, especially during the reproductive period, when male narwhals will use this horn to fight for the right to reproduce."
