Now, the shark, the king of the sea, is on the boom
It became a hot topic on SNS
The goods related to sharks are also very popular
But speaking of sharks, it's a little scary
There is no such thing as human-eating sharks
That's right
There are two things that sharks have
The evolved shark has a great ability
They are going to attack a mysterious creature
Stand up!
Bow!
Nice to meet you!
This time, the special instructor is Mr. Asako Numaguchi
As the only shark journalist in the world,
he is a professor who is studying and interviewing sharks all over the world
Do you like sharks, teacher?
Yes, I love them
You have a shark in your mind
My whole body is a shark and my house is also a shark
I love sharks. What do you mean?
My house is a shark house.
From the wall of my house to the furniture.
You are the only one who has a shark house, right?
That's what I call it.
I have a shark's jaw on the wall.
I have about 30 of them in one room.
Are you sleeping there?
Yes.
Don't you have a weird dream?
I have a fun dream.
I have a shark's jaw.
In the past few years, books and goods related to sharks have become popular, and the number of shark lovers has increased.
Speaking of the beginning of the shark boom...
In the 1970s, it was the beginning of the shark boom.
However, since then, the image of sharks has become quite scary.
For example, when a shark appears in a seawater bath, it is forbidden to swim.
In fact, there is no such thing as a type of shark that eats people.
In fact, they are all cowardly and cute, so I don't want you to think that way.
I thought that sharks eat people.
The fact that there are no human-eating sharks means that sharks are not animals that attack people in the first place.
That's right. They don't attack people anymore.
For example, there is a shark called itachi shark in the south of Okinawa.
Its favorite food is a sea turtle.
When it eats a sea turtle, it looks up at the shark from the sea and recognizes the food.
At that time, the person on the surfboard who is paddling seems to have a similar silhouette.
Therefore, it is speculated that the shark has bitten it.
I'm a little scared because I'm a fan of sea turtles.
I want to buy a big one like that.
From the bottom, it looks like a turtle.
The hand is like this from the side of the surfboard.
That's right. Also, the shark has the habit of eating as weak as possible.
There is a theory that the sound of paddling is similar to the vibration of a weak fish.
That's why it attracts sharks.
Let's take a look at the charm of sharks.
White carp shark Ecology of white carp How many types of sharks are there?
According to a 2014 paper, 509 species have now been identified.
509 types!?
How many sharks are there that can attack humans?
said to be less than 1%.
Which of the largest shark species would you say?
A kind of whale shark.
They grow up to a total length of 17 meters.
This giant shark is really big, but is there a smaller type of shark?
Yes, there is. It's the smallest shark in the world, and it's the size of this palm.
It's black and really small, but if you look closely, you can see the gills of the shark's gills, and the teeth are jagged.
It's a long-standing friend of sharks.
Can you eat plankton around here?
Yes, because it is often confused with cherry shrimp, it is thought that it mainly eats cherry shrimp.
Next, let's take a look at the life of sharks that are not known.
First of all, the shark's ____ will change every two or three days.
What is it?
The shark's ____ will change every two or three days.
The quality of the ____.
What happens every two or three days?
The shark's ____ will change every two or three days.
Scary! It's gross!
What does it mean?
It's a momentary change.
It happens suddenly, doesn't it?
Uuka?
____.
Oh, the shark's ____ will change every two or three days.
The shark's ____ has a strong image.
Let's see the correct answer.
Shark's ____.
Uuka is correct.
It's said that it will continue to grow and grow until it dies for the rest of its life.
If there are a lot of sharks, they can grow up to 70,000 in their lifetime.
That's amazing.
Does this mean that the teeth fall out?
That's right. If the front teeth fall out, it feels like they're on the muscles.
The muscles come out like a belt conveyor from behind, and the teeth on it come out little by little.
It comes out like this?
It comes out like this.
That's amazing.
It seems that there are characteristics for each type of shark. Let's take a look.
There are various types of shark, but they can be divided into these three.
Let's start with this blue shark.
This blue shark is a type of hawk.
For example, it is a type of shark that does not have a jagged teeth like a hawk.
Therefore, it is a type of shark that is very suitable for eating big fish.
The blue shark next to it is a type of shark that has jagged teeth like a hawk.
The teeth themselves are jagged, and in the case of the blue shark, the teeth are thick, so this can be used as a shell of a sea turtle.
Sea turtles, mammals, and when the blue shark is released, sea birds and so on come out, and anything, and it's a cat shark, but
it's cute when the mouth is like this. What kind of mouth do you think it is?
What you can actually see from the outside is the front teeth of the upper teeth, and this is the front teeth of the lower teeth, so you can only see it from the outside.
This cat shark loves sardines and sea urchins, so eat it with shellfish and crush it with a tooth like a cow in the back.
There is a habit of eating the contents, so it is said that it evolved into a tooth like this, so it seems to be stabbed.
The next unknown life form shark skin is the same material as the one
Do you know what it is?
Mamone Helicopter
Bitoon? Bitoon? Bitoon's skin? Bitoon is shark skin.
It's hard, isn't it? Because it's shark skin.
Ha-san? Concrete.
I see. I see. I understand.
I didn't raise my hand, but it's here.
It's a sponge.
Can you be motivated?
You said you'd be motivated in the future.
But I didn't raise my hand, so it's a sponge.
It's the opposite.
Let's take a look.
What? Again?
The correct answer is teeth.
teeth?
I've never heard of it.
Is it the same material as shark's teeth?
Yes, that's right.
Tooth is made of enamel.
Tooth is made of the same material as shark's skin.
In the case of Yumewake, it's so sharp that just touching it will cut your hand, yes, it's shark teeth.
It's dangerous.
It's really shaped like a shark's tooth.
It's good at a sushi restaurant, the guy doing this.
Like wasabi?
Oh yeah, those are shark teeth.
Eh, is that so?
Is that so? Are you pasting it?
If you didn't know, I would have done it.
No, hey, don't cut it!
That's it.
That's all.
Sharks have two reproductive organs. Let's take a look at the actual photo.
The shark is a shark called star shark, but the top is female and the bottom is male.
It's more genital than you think.
This arrow is called a clasper.
Clasper?
It's technically called a clasper.
Don't worry about your nails.
What is your teacher holding?
What I want you to see is a shark tooth in the nail.
shark teeth?
The white parts are shark teeth.
This contains the teeth of a shark called silky shark.
I'm a big shark today.
I'm still wearing shark teeth today.
Uh, shark teeth? Uh, you mean you like looking at shark teeth?
I like being one with myself.
A shark is in his body. It's hentai.
You say it well. It's hentai.
It's the same as a shark.
This is a big shark.
This is a shark clasper that is up to 12 meters long.
This is me.
What are you thinking about?
This is a big shark.
This is a fish.
However, there is a rare habit of mating.
Normally, they don't mate.
They mate where they lay their eggs.
There is a mystery that there are two of them even though one should be enough.
Is this still a mystery?
There are several theories.
One is that it is advantageous for survival.
One theory is that even if one is accidentally lost, it can be left by descendants.
The other theory is that this is a belly fin.
The belly fin is deformed and there is something hard attached to it.
There are two belly fins.
When I see sharks in the natural world, I sometimes find one without a belly fin.
Is that so?
I personally think that the first theory is advantageous.
Does this mean that sharks mate because they are fish?
That's right.
It is written that sharks mate because they are fish.
That's great.
I knew it for the first time.
When they mate, they are really ferocious.
The female swims in parallel with the male.
The male bites the gills and chest fins.
It bites.
When the female is unable to move, it bends the gills and shoots.
That's crazy.
The female is really ferocious.
When you see it in the sea, it looks like it's going to die.
But sharks are quite strong, so it's been about a year.
That's a long time.
It's been a year.
That's a long time.
Does it mean that it runs away?
That's right.
When the female runs away, the male bullies it.
That's a bad guy.
But I think it's good for the sexual hormones to come out.
It's a do-em.
Why are you on the female side?
When I heard that, I thought it was a do-em.
It's a do-em.
It's do-em.
The female shark is the one that causes hormones.
What about the male shark?
I think it's the one that was bitten.
See? It's a do-em.
It's strange to look at.
It's a do-em.
If it's bitten, it'll go like this, right?
There's a theory that it will.
It won't bite.
It won't bend.
Up until now, there have been 509 types of sharks that have been confirmed.
From now on, we're going to learn about sharks that have slightly different characteristics.
First of all, this is a cat shark.
It looks very cute.
According to one theory, it has a cute expression like a cat.
That's why it's called a cat shark.
It's not the shark we're imagining.
Here's the quiz.
This cat shark lays a slightly strange egg.
Which of the following three is it?
Think about it.
If you think it's A, that's the shape of an egg.
It's changed a lot.
B.
C.
It's a shark.
There are a lot of C's.
It's a shark. It's like a caviar, isn't it?
Oh, I see.
It's C.
I see. Let's see the correct answer.
Here is the correct answer.
A.
This is an egg.
Wow, that's amazing.
It's a rare form.
How big is it?
It's about the size of a palm.
It's about this big.
It's big.
Is there one in this?
Yes, there is one.
Two females are born in one time.
About 12 are born in one season.
Why is it shaped like this?
There are several reasons.
Actually, this shape is very similar to a mekabu.
In the area where catfish live,
There are also areas where mekabu can be caught well.
Probably, the mother shark gave birth to this egg.
It's hidden in an environment where there are similar plants.
It's like a drill on a rock.
It's easy to bury.
That's why it evolved into this shape.
That's amazing.
Let's see the correct answer.
The correct answer is B.
B is also a strange shape, but B is a shark called Nanukazame.
Is this also an egg?
Yes, this egg is also called the wallet of a mermaid.
This was often found on the shore of the waves, and the person who picked it up thought it was the wallet of a mermaid.
It was called like this.
This is also a characteristic of Nanukazame's shell.
There is one in it.
And it's C.
C is what I said earlier.
Caviar.
This is a shark's egg, so it's caviar.
In fact, a shark is not a friend of a shark.
It's a completely different kind of fish, so it's a shark with the name of a shark, but it's a completely different animal from a shark.
I thought it was a shark.
Maybe it's because the face is similar, the mouth is on the bottom, and it looks like a shark.
The next interesting shark is this one.
What is this?
Mitsu-kuri shark. What kind of shark is this?
This is a shark that lives in the deep sea.
Looking at it like this, I think it's an ordinary type of shark.
Is it because this part is long?
That's right, but it has a very interesting feature.
In fact, the name of the devil shark is Goblin Shark in English.
Goblin Shark
It's creepy.
Its skin is dirty.
It's a deep sea shark, so it's a little rough when it comes up shallow.
So it's supposed to be a little cleaner.
It's scary.
Oh, it's touching.
It's mouth is open.
Another one came out from the inside.
It has a characteristic that the jaw of the mouth jumps out.
In the case of sharks, any shark can jump out of its mouth.
It's very rare to jump out that much.
What's more amazing about this shark is the speed at which its jaw comes out.
It is already calculated to be 3.1 meters per second. It's so fast that you can't see it with the naked eye.
Here's what's interesting next. Scalloped hammerhead shark.
Its Japanese name is Hammerhead Shark, but in English it is called Hammerhead Shark because it has a big hammer-shaped head.
This strangely shaped head is very distinctive,
The shark's head has a sensor called the sixth sense, which we humans don't have.
In technical terms, it is called the Lorentini backbone.
For example, even if we have crabs in the sand, we can't see them, so we can't prey on them.
In their case, they are able to sense the faint bioelectric current emitted from these invisible creatures and prey on them.
That's amazing. You mean you can eat it even if you can't see it at all?
That's why I widened the area of the head where the sensor is located, I think it's good.
It is said that the hammerhead shark is one of the most evolved sharks out of 509 species of sharks.
The top of the shark world, the latest generation.
This shark has many interesting episodes,
It seems that she gave birth to a child when she was keeping only a female striped hammerhead shark in an aquarium.
female only?
female only. The people at the aquarium were surprised,
I did a lot of research to find out what this was, and after looking at the DNA,
After all, I found out that there is no illegal gene and it is like a clone of the mother of the maternal gene,
It's only in the aquarium, but I've been progressing with the play that I can make clones of my friends.
a child has been born. Well then, it doesn't have to be a full year.
However, if the genes of males and females do not match, the diversity will disappear and they will end up becoming weak creatures , so I think it is better to diversify the genes.
Here is the next interesting maker.
Tenjiku shark with magic crest. What kind of shark is this? It's called a walking shark.
walking shark. It means walking.
It's really a shark, but it's a very interesting shark that has evolved to walk instead of swim.
cute. She's so cute. Notice the pectoral and ventral fins.
I'm just swimming right now.
Oh, you're walking.
She's so cute.
quadruped direction.
It's a friend that has several species from the southern part of Australia to Papua New Guinea.
I'm walking I'm walking
The figure walking on the coral reef is really cute.
Do some people buy this as a pet? Should I buy this?
You can buy this, so I'm selling it.
It seems to be popular and cute.
However, there are only Australia and Papa New Guinea, so it's fine, the price is high.
How much? If I were to buy one.
I think it's probably about 200,000 Japa.
got it.
Then there is the shark named for its appearance. here.
megamouth shark. You have a big mouth. Sensei, this is. that's right. The mouth is big, so it's a mega mouse. It means mouth. mega mouse. This shark is very rare, and until just 40 years ago, no one knew about it.
It was amazing that in this day and age on Earth, giant creatures are not recognized.
Currently, about 200 individuals have been confirmed worldwide. The balance is strange, isn't it?
But it really is. As for what they eat, they eat the same plankton as whale sharks.
However, the way of eating is completely different. In the case of whale sharks, I'm sure some of you may have seen the whale shark sucking with a great boom when feeding it at the aquarium, called a suction installation.
This is, this is inflated like a balloon,
It is speculated that they are eating this krill and plankton all at once.
However, they are still too rare to be studied, so no one has yet seen them predating.
So it's a shark shrouded in mystery.
Did you mean earlier that a dead megamouth shark was found?
I agree. It is said that a live shark got into the net and died in it, so it was pulled out and used as a specimen.
For example, if you give him a living egg and do it in a aquarium, will it become a great eye ball?
It's a great thing in the world.
But we don't know how to raise it yet.
There's a high possibility that he'll die right away.
That's right. As long as we don't solve that, it's hard to raise it in a aquarium.
It's an interesting story.
Now, let's announce the prize or punishment game for KASHIKO, who was excellent last week.
I'll announce it.
This week's KASHIKO is...
Wooker!
The correct answer is bones grow back.
And this week's candidates are...
Chichi and Coconor!
chi-hi said bones grow back.
Coconor said I'm too careless.
This time, we will have a quiz about sharks that don't exist.
Among the five sharks that really exist, there is one that doesn't exist.
The person who gets it right will be the loser.
Rock-paper-scissors.
I'll go first.
You'll go first?
Yes.
This is hard.
Then, I'll go with a sawed-off shark.
Sawed-off shark.
Sawed-off shark is...
Here it is!
Next, Kokona.
Here it is.
Sawed-off shark is...
Here it is!
This is hard.
Sawed-off shark is...
Not here!
Only sawed-off shark is not here.
It seems to be here.
It seems to be here, but it's not here.
So, Chihirikete!
There is a sawed-off shark.
