How long can a missing person be declared dead
Different countries have different regulations on this issue. Generally speaking, it is about three to five years, and shorter or longer is not uncommon.
So, how long before a whale is missing can it be considered dead
Hard to say.
It's been almost 30 years since the whale, dubbed "52 Hertz" because of its unique vocal range, was discovered in 1989, and it's at least in its 30s.
The lifespan of whales is generally very long, much longer than 30 years, but too many things can happen in 30 years.
And it hasn't been heard from since 2004, 15 years after its discovery.
Reminiscent of some countries in the world still going out to sea to hunt whales, whalers will not distinguish the sound of the target before shooting a harpoon. For them, a whale is a whale, nothing more than a huge mass of flesh and blood, there is no difference.
This can't help but make people worry about the fate of 52 Hz.
Zhang Zian had read stories about it before, but when he learned that it hadn't shown up for many years, he also tended to think that it was dead, maybe from old age, or from natural causes, such as encountering a large group of killer whales in the sea , or encountered health problems, and of course may have died at the hands of whalers.
When he met the mysterious giant whale, he had already forgotten the story in the corner of his memory. He didn't realize that the other party might be 52 hertz. After all, the ocean is too big and there are many giant whales in the ocean. Maybe it just happened to come across it? How is it possible to see a giant whale and think it is 52 Hz
You know, people have only heard its voice before, but no one has ever seen its real body, and they are not even sure what kind of whale it is.
The only way to determine 52 Hertz's identity is by its sound; no other method is reliable.
Just now Zhang Zian played the sound of this giant whale on his laptop, and found that its sound range is very unique, between 45 and 50 Hz. He didn't immediately think of 52 Hz, but thought it was another whale nearby. Fortunately, he immediately denied his guess, and then recalled the related rumors on the other side that the sound of 52 Hz was 52 Hz when he first discovered it, but it gradually became deeper and deeper, which coincided with 45 to 45 Hz. 50 Hz range.
Previously, 52 Hz often wandered from the west coast of the United States to the waters of Alaska, that is, the Northeast Pacific Ocean. Could it be that it ventured to the completely unfamiliar Western Pacific Ocean, that is, near Northeast Asia
This possibility exists, after all, it is an alternative.
Since it arrived in the western Pacific, scientists on the West Coast of the United States have lost track of it.
The long coastline of Northeast Asia, many places are desolate and backward areas, without coverage of accurate underwater listening system, it is normal not to record its sound.
It may be due to some kind of opportunity, for example, it heard Shihua's singing, although it may not understand it, but it also felt the loneliness in the singing, so it followed the singing to the sea outside Binhai City, and lingered nearby.
The closest route between the pet shop and the sea is the beach that Zhang Zian often goes to, so it always appears there, meeting Zhang Zian unexpectedly.
What is it waiting for
What is it expecting
After figuring it out, before Zhang Zian had time to figure out how to deal with this discovery, he was overwhelmed by Shihua's crying...
Shihua, Fei Na, Lao Cha, and π were all very engrossed in listening, as if following Zhang Zian's narration, they also traveled the entire vast Pacific Ocean with the loneliest whale, witnessed countless magnificent beauties, and witnessed countless times. The weak and the strong in the ocean have called out to the same kind countless times but have never received a response.
It is consumed by a bottomless loneliness, as if abandoned by the whole world, without being disheartened.
In particular, Shihua touched me the most. Like it, she is truly unique, and there is no other like it in the world.
She wept silently again.
Today, she no longer knows how many times she shed tears. This time, it was not for herself, but for the fate of 52 Hertz, for its 30 years of tireless search, and for its courage to come across the ocean.
No one can imagine how it spent 30 years alone.
The old tea sighed: "It can be said that it can be said that dust and earth for thirty years of fame, eight thousand miles of cloud and moon... it has traveled all the way with only clouds and moon as its companions. Who knows how hard it is?"
Even Fina, who is usually not pretentious, nodded in approval.
"That..." Shihua raised his head, with crystal tears rolling in his eyes, he choked up and said, "What can we do for it?"
Zhang Zian said: "Some people speculate that 52 Hertz may be the offspring of a hybrid between a blue whale and a fin whale. After seeing it with my own eyes, I think this guess is very reasonable. Its greatest wish should be to find another similar to it. But it's difficult because even if there was another whale that was also a hybrid, it wouldn't necessarily be using the 45 to 50 hertz band."
The courtship and mating of whales is quite meaty and unscrupulous. As long as they are relatively similar in size, even different types of whales may spark passion.
There have been rumors of interbreeding between different species of whales for a long time, but due to the vastness and depth of the sea, confirmed examples are extremely rare.
The Discovery Channel once told a case that a researcher came to Fusang and bought whale meat from the Fusang market. The original intention was to study the DNA of the whale meat to trace its source, but it turned out that the DNA of this piece of whale meat showed that it was a hybrid, from Blue Whales and Fin Whales.
It is quite a pity that a rare hybrid whale was sent to Fusang's dining table in this way.
However, blue whales and fin whales can mate and give birth to hybrids. In addition to their similar size, another reason may be that their voices are both around 20 Hz, and they can find and communicate with each other.
There are not no whales that can emit 45 to 50 Hz sound, but the size of those whales is far from 52 Hz... If you insist on mating, the picture is too beautiful to imagine.
Zhang Zian continued: "It's almost impossible for 52 Hertz to find its kind, and we can't help it find it... But that doesn't mean we can't do anything. Although we can't help it find its kind, we can make it rekindle. Hope. There's only one way if you want to help it."
"What way?" Shihua asked impatiently.
Zhang Zian didn't hold back, and replied directly: "You can learn its singing, and then use the same voice segment to tell it not to be afraid, you are not alone."
