I was blown away by the longing for the live broadcast of the sea
Chapter 666 An unexpected new discovery, an extremely endangered and rare creature forced to migrate
Chapter 666 An unexpected new discovery, an extremely endangered and rare creature forced to migrate!
In the early morning, the sun was rising, the sea breeze was warm and pleasant, and the small red flag on the flagpole of the yacht was fluttering in the wind.
As for the dinosaur-like whales previously discovered in the Caribbean Sea, after being fueled by online platforms and news media, it naturally attracted many new viewers to Lin Yang's live broadcast room.
"I really regret that I only pay attention to such a treasured anchor now. I missed a lot of exciting content before!"
"Good guy, no one really paid attention to the anchor when the sea trip was almost over, right? No way, no way (manual dog head)"
"To be reasonable, I'm also very interested in the Nordic countries that the anchor will go to next, so it's not too late to pay attention now!"
"Then the question is, when will the anchor arrive at the next destination?"
At this moment.
Yue'er is in the cockpit of the yacht. While controlling the yacht, she chats with the water friends one after another.
Lin Yang, on the other hand, has been paying attention to the specific location of the A-level rare creature that was previously scanned by the radar.
Because the yacht keeps moving forward, the distance between the target creature and the yacht is naturally getting closer.
However, at this moment, in the footage of the live broadcast room, a small black spot seemed to jump up on the distant sea.
This unexpected discovery instantly attracted the curiosity of many water friends!
"I'll go! What is that? A dolphin? It shouldn't be. How can a dolphin be so small?"
"It feels like seabirds are flying out of the sea?"
"It is true that many seabirds can float on the surface of the sea."
"When Lin Yang's camera zooms in, the answer will be clear."
at the same time.
After Lin Yang photographed the little one jumping out of the sea not far away, the system immediately gave a feedback that made him a little confused;
[Congratulations to the host!World's smallest cetacean discovered: the vaquita!Attributes: Chordate, Mammalia, Cetacea, Porpoise!Original active range: Northern Gulf of California, Mexico!Current active area: Migration status! 】
no doubt.
Such a sudden reminder feedback from the system made Lin Yang a little confused for a while.
After all, he had some knowledge about creatures like vaquitas.
The current location they are in is the Caribbean Sea heading northwest, and there is still a certain distance from the northern Gulf of California, where creatures like vaquitas are often active.
That is to say, in the waters where vaquitas are unlikely to appear, they actually discovered the smallest cetacean creature in the world during their voyage!
The so-called vaquita, in terms of appearance, is actually not much different from ordinary dolphins.
But their overall shape is relatively chubby.
In addition, if you observe carefully, there are other differences.
At this moment, tens of millions of water friends in the live broadcast room are naturally very curious about the things captured by the distant lens. After all, no one knows what kind of marine life is captured by Lin Yang's lens.
Because the distance is relatively long, even if it is a relatively clear high-resolution camera lens, the amount of information that can be obtained by the eyes is still very limited without zooming in on the focal length.
In the cockpit of the yacht, Yueer frowned slightly and stared at the electronic screen. She tried to capture the images sent back through the camera to determine what creature was found.
Although this girl was considered a novice in marine life when she set sail from Alaska, but during the sea voyage with Lin Yang, this girl did not spend less time studying the relevant knowledge of marine life.
Compared with ordinary people, her current marine life knowledge reserve can be regarded as relatively rich.
It's just that this kind of richness is only relative to ordinary people. If what is found is a relatively unpopular and rare marine creature, the girl's eyes are still smeared, and she can't tell the difference.
Yue'er stared at the electronic screen and muttered to herself: "Brother Yang, the thing photographed in the distance seems to be a dolphin, but it looks a bit strange."
Lin Yang nodded.
However, although tens of millions of viewers were looking forward to what Lin Yang could say, he didn't say a word other than nodding his head to confirm Yueer's guess.
At the moment, the number of sand sculpture netizens in the live broadcast room has surged in the number of barrage messages!
"In my opinion, it should be an ordinary dolphin, right?"
"There are many species of dolphins, maybe the anchor captured a rarer species?"
"If you make some bold guesses, will it belong to a new subspecies like the Pacific panda dolphin discovered in the Pacific Ocean?"
"Although the ocean world is extremely vast, it shouldn't be particularly easy to discover new subspecies?"
"Brother in front, it seems that you have been following the anchor for a short time. Let alone a new subspecies, during the previous anchor's sea voyages, many new species have been discovered!"
Lin Yang glanced at the barrage message in the live broadcast room, and then he said with a smile: "This is not a new subspecies of dolphin, but compared with ordinary dolphins, it is indeed a bit special."
What he said once again aroused the strong curiosity of the audience in the live broadcast room!
Although the footage in the live broadcast room is not a new subspecies of dolphin, Lin Yang does have something special. What does it mean?
Sand sculpture netizens are naturally very puzzled.
"What's special? Could it be that this little dolphin doesn't eat meat and lives on a vegetarian diet?"
"Their size looks a bit different from normal dolphins."
"In other words, the specific special features exist on top of their physical characteristics?"
"When the camera can shoot more clearly later, the answer will naturally be revealed!"
This is true.
In Lin Yang's lens, the clarity of the image of the little dolphin that can be captured is still relatively blurry.
Therefore, ordinary water friends still need to spend a little effort to distinguish the special features of this dolphin with the naked eye.
At this moment.
Yue'er stared intently at the electronic screen in the cockpit of the yacht, trying to capture every detail captured by the camera.
However, the girl looked left and right, and she couldn't see the general difference between this dolphin and ordinary dolphins at a long distance.
"It doesn't look like there's anything special about it, at least in terms of appearance, apart from being slightly chubby, there's no difference."
As Yueer said.
The vaquitas currently appearing in the camera, in addition to their fat bodies, their markings are also another condition for identifying species.
Under the eager anticipation of thousands of water friends, as the yacht approached, the image of the little dolphin in the screen gradually became clearer due to the change of distance.
At this moment.
All water friends seem to have noticed some small details!
"Look quickly! This little dolphin seems to have black circles around its eyes!"
"Good guy, is this the result of being so playful that you don't want to sleep? It's the same as me playing with my phone at night qaq."
"This should be similar to dolphins like the Pacific Panda Dolphin, born with special leopard prints, right?"
"Brother in front, I think your analysis is more reliable."
Lin Yang didn't keep it secret, he said straight to the point: "This kind of dolphin is called vaquita, which is a small cetacean creature. From the appearance, they are slightly fatter than the most common dolphins. The most iconic feature is Count their dark circles."
Because of the close distance, the dark circles under the eyes of the vaquita captured in the camera are very obvious.
Around the round eyes of the vaquita, black eye circles are extremely evenly distributed.
As described by the audience in the previous live broadcast room, the dark circles under the eyes of this vaquita looked like they had been born without sleep for several days.
"Brother Yang, didn't you say before that the overall number of this kind of dolphin is very rare? I have never seen this kind of dolphin before!"
Yue'er was naturally very curious about this kind of dolphin with dark circles.
However, what Lin Yang said next surprised tens of millions of fans in the live broadcast!
He nodded, cleared his throat and said, "The number of this kind of vaquita is indeed extremely rare. According to incomplete statistics, there are only about 150 in the wild now."
Lin Yang looked at the vaquita in the camera, frowning slightly when he said this.
Hearing this, Yue'er opened her mouth slightly with surprise on her face.
Although Lin Yang mentioned before that the number of this kind of vaquita is relatively rare, even Yue'er did not expect that there are less than 150 of them!
"So, this vaquita is a properly endangered species!"
Yueer said incredulously.
Lin Yang nodded and replied: "On the one hand, they are rare. On the other hand, their habitat is not in the Caribbean Sea, but in the Gulf of California, Mexico. It is a matter of fact that they appear on our route. Very strange thing."
The porpoise, which is related to the vaquita, has a relatively wide distribution range, and there are relatively large numbers living in the wild now.
Like porpoises, vaquitas prefer relatively shallow waters.
However, the actual depth of the Caribbean Sea they are in is not shallow.
In other words, it may be due to other special reasons for survival that the vaquita, which lives in the northern Gulf of California, Mexico, appeared in the waters around the Caribbean Sea.
In this regard, the audience in the live broadcast room also noticed the clues.
"The anchor means that these creatures called vaquitas are unlikely to appear in this sea area?"
"I think it should be because their habitat has been destroyed, so they are forced to migrate?"
"They look so cute, they are more chubby than normal dolphins!"
"Especially the small dark circles, which are similar to pandas! In my opinion, they are called panda dolphins more appropriately!"
"The most important thing is that the number has become so rare that I didn't expect it."
In fact.
In the ocean world, many creatures are on the verge of extinction, and these are inseparable from human fishing operations.
Of course, in terms of the reduction in the number of small-headed porpoises, it has nothing to do with Longguo.
First of all, most of the seafood supply in the current Dragon Kingdom is from artificial fish farms, and the proportion of wild catches has been declining year after year.
Secondly, although porpoises can be found in the Haizhou Bay Fishing Ground of the Yellow Sea in Longguo and Lusi Fishing Ground, they are strictly protected.
Secondly, this kind of vaquita is not distributed in our country.
Lin Yang went on to say: "The decrease in the number of vaquitas is related to various factors."
Overfishing, habitat encroachment, and water pollution in living areas have drastically reduced the number of vaquitas living in the wild.
However, the most embarrassing thing is actually.
If Lin Yang hadn't accidentally photographed this rare and endangered marine creature in the camera of Lin Yang's live broadcast room, at least for ordinary viewers, even the name of the vaquita had never been heard of.
Lin Yang went on to say: "Although in 2009, Mexico officially issued a resolution to ban the use of harmful fishing nets in the waters where vaquitas live, but it still cannot change the fact that the number of vaquitas is already in danger."
Because of his words, many water friends in the live broadcast room have a common doubt.
Can it really work as a remedy after a dead sheep?
At least the scene captured from the footage of the current live broadcast room is enough to prove that it is a useless strategy when it is too late!
Although after realizing the sharp decline in the number of vaquitas, Mexico, the country where the habitat is located, issued relevant protection strategies.
However, the fact that the number has dropped sharply has been irreversible.
The polluted water source cannot be purified again, the encroached habitat cannot be restored again, and the vaquita killed by destructive fishing nets cannot be revived.
therefore.
In the subsequent assessment of the IUCN World Conservation Union, the vaquita was judged to be an endangered marine creature.
It is precisely because of the understanding of the cause and effect that the audience even felt that it was reasonable for Lin Yang and the others to find such a very small number of vaquitas in the Caribbean Sea.
When the habitat is destroyed, when the living environment is greatly threatened, in order to preserve the continuation of the species, it seems logical that they leave the habitat under natural selection.
However, even ordinary water friends in the live broadcast room seem to be able to imagine that the vaquita, which likes to move in shallow water areas, needs to have great courage in migration when entering the deeper waters of the Caribbean Sea!
However, if we don't leave the original habitat and wait for the end of the vaquita, I'm afraid it will be a collective annihilation!
In order to avoid this situation, they have to leave their hometowns under difficult choices.
Perhaps in the eyes of ordinary people, this is just wild marine life migrating to another sea area to seek a way of life.
But the reasons behind it can't help but make people fall into contemplation.
After all, within the limited time for the human scientific system to detect wild creatures, changes in the temperature, oxygen, and humidity of the earth itself are very limited within the limited time.
Therefore, it is almost impossible for a catastrophe such as the Cretaceous, Jurassic or even Devonian to occur.
Therefore, under natural evolution, the extinction and reduction of species has little to do with environmental changes.
Because of this, whether it is the extinction of species around the world, in most cases, it is inseparable from human factors.
Thylacine in Australia, great auk and Stella sea cow in the Arctic, and iconic creatures such as the dodo.
The reason why they disappear from the earth is not because of natural enemies, but because of human beings.
In the footage in Lin Yang's live broadcast room, the vaquitas were recorded migrating in groups. They sometimes jumped out of the sea slightly, and the number was about 6-7.
If you don't know their past and present lives, at least in the eyes of ordinary water friends, this is an ordinary group of dolphins, living carefree in the vast ocean world.
But because of Lin Yang's related popular science, more people have a little understanding of this embarrassing biological group.
"They look chubby, so cute!"
"After the yachts approach, will the anchor have close contact with them?"
"I think they should be afraid of humans? Maybe not? I'm just guessing."
"Hopefully their populations can grow stronger and their numbers can recover to get rid of the endangered situation."
"The dark circles under their eyes look so funny, and the cuteness factor also has a lot of points because of the dark circles!"
True.
While Lin Yang was shooting and recording the vaquita, ordinary sand sculpture netizens were amazed at seeing this smaller cetacean creature for the first time.
The pictures he took have also attracted the attention of professional research institutions in the related marine field.
Almost at the same time, the French National Institute of Marine Biology posted a tweet on its official channel——
[According to my research institute's data on vaquitas, the number of vaquitas that can be found in the northern Gulf of California, Mexico, has reached a new low in the past three years!The number of evaluations is about 100 or less.Mr. Lin Yang was able to find this kind of marine life in the Caribbean Sea, which seems to prove that they have been gradually forced to leave their habitats. Perhaps after leaving the shallow sea area near the coast, the vaquita may really find their habitat! 】
The French National Oceanographic Agency is relatively authoritative in the field of global marine biological research.
As early as 1984, the institute was merged by the Bresque National Marine Development Center and the South Side Marine Fisheries Science and Technology Institute, which formed a new institution called the French National Marine Research Institute.
Under its national institution, there are a total of 5 research centers, namely 'Brest Marine Science Center', 'Boulogne-sur-Mer Aquatic Research Center', 'Nantes Marine Fisheries Science and Technology Institute', 'Toulon Mediterranean Marine Science Base', Tahiti Pacific Marine Science Center'.
The agency's detection data on vaquitas in the northern Gulf of California, Mexico, is relatively accurate.
Therefore.
The audience in Lin Yang's live broadcast room couldn't help but sigh.
This cute little dolphin looks like a panda with black eyes. Even though it is chubby and cute, there is no shelter for them in the vast and boundless ocean world.
