Shadowing Practice: What If Megalodon Met the Biggest Snake Ever - Learn English Speaking with Video
Creando lección...
1
This is going to be a very unusual match, but I bet it'll also be spectacular and intense.
2
In the left corner, we have Megalodon.
3
This species went extinct about 3 million years ago, but there are good reasons why it's now a legendary animal.
4
It's the biggest shark that ever existed, and it was a super powerful predator in its time.
5
And a round of applause for our contender in the right corner, Titanoboa.
6
This one's way bigger than any other snake.
7
It lives in the swamps of Colombia, and it's the real boss of the area.
8
Titanoboa can eat absolutely any animal it decides to hunt, and it faces no competition.
9
It can swallow a giant turtle or even a crocodile.
10
It looks like a modern boa but behaves like an anaconda, and that's a very scary mix!
11
But can it stop a giant shark?
12
Let's start by looking at their sizes.
13
We still don't know about Megalodon's exact size, because the only remains of them that have survived are just fossilized backbones and teeth.
14
But scientists generally think this monster was about 50 feet long.
15
So it wasn't just the biggest shark that ever existed, but also one of the biggest fish of its time.
16
Its closest rival is the modern whale shark, but they're only about 40 feet.
17
The giant Titanoboa got so big thanks to a lucky coincidence since.
18
Snakes are cold-blooded animals, so they need a warm climate to live and grow in.
19
Northeastern Colombia is perfect.
20
It was about 90 degrees when Titanoboa was alive.
21
This helped it grow to an incredible 42 feet in length.
22
Titanoboa could easily swallow the longest snake registered in the Guinness Book of Records, which is only about 25 feet long.
23
And that's a big gulp!
24
So we have 50 feet versus 42.
25
The first point goes to Megalodon.
26
What about weight?
27
Titanoboa is about 2,500 pounds.
28
That's heavier than a small car, including the passengers.
29
But it might be even heavier if you run into Titanoboa after it's had lunch.
30
In that case, you can add a few hundred pounds more from the turtle or the alligator that it just swallowed.
31
If you put Titanoboa on some very large scales, you'd need 5 giant anacondas on the other side to balance them out.
32
But Megalodon is an incredible 50 times heavier than Titanoboa.
33
The average adult female weighs between 27 and 59 tons.
34
That's as much as an empty Boeing 737 airplane.
35
And that's without carry-on luggage, either.
36
Luckily enough, Megalodon can't fly.
37
So obviously, Megalodon wins in the weight category.
38
That's one more point to the ancient shark.
39
Although having such a large weight makes it difficult for the shark to move and also means it's a little clumsy.
40
Which leads us to our next category, speed and agility.
41
Megalodon can swim at about 16 feet per second.
42
That's enough to make it the ultimate predator.
43
But it's still slower than plenty of other species.
44
If Megalodon was swimming in a pool and Usain Bolt was running along next to it, he would be twice as fast.
45
His top speed is almost 40 feet per second.
46
Now a sailfish, which is the fastest sea creature, can reach about 100 feet per second.
47
Giant size and weight make it turn really slowly, just the same as a large truck.
48
So when it attacks, the shark has only one chance to strike.
49
If it misses, it has to go around for a second attempt.
50
This gives its prey more than enough time to run away.
51
Titanoboa isn't that fast either, especially on land.
52
But when the giant snake is in the water, it can swim at a speed of up to 12 miles per hour.
53
Not much, but enough for it to escape from Megalodon if it needs to.
54
It's learned to swim so well because water is its main hunting ground.
55
And because Titanoboa is a snake, duh, it also has incredible mobility.
56
It can wriggle around and change direction very quickly.
57
So it can easily dodge Megalodon's bite.
58
So here's the first point for Titanoboa.
59
The score is 2-1 in favor of megalodon.
60
Next section, fighting skills.
61
Megalodon is incredibly smart.
62
It can change tactics depending on what kind of prey it's hunting.
63
Scientists have found teeth markings from megalodon on some whale fossils.
64
These show that the giant sharks aim their bites at their prey's vital body parts to take them out quickly.
65
Other remains of Megalodon's victims have multiple fractures.
66
This is because Megalodon performs a super-powerful ram attack that can knock almost anything out.
67
In fact, this 50-ton beast can easily smash through concrete walls.
68
So, Megalodon's opponents don't really stand a chance.
69
Some of them prefer to first damage the tails and fins of the whale they're hunting.
70
This stops it from escaping, letting the huge predator finish off its defenseless victim.
71
Now, what can Titanoboa do in response?
72
The giant snake isn't poisonous, but this doesn't stop it from hunting prey up to 4 meters long.
73
Its bite has a very special design.
74
The structure of its teeth and jaws lets Titanoboa really clamp down on the body of its prey, so there's no escape.
75
When hunting, Titanoboa uses similar tactics to an anaconda or a boa.
76
By that, I mean it uses its powerful muscles and weight to stop its prey from moving.
77
It deploys all of its strength to take away the animal's energy, making it helpless.
78
So Titanoboa is not only really speedy and agile, it can also fight its corner pretty well.
79
It's definitely earned a point in the fighting skills section.
80
The score is now 2-2!
81
That's a tie going into the final round!
82
We've got one more section before we find out which of these ancient monsters will win!
83
Up now is Fighting Tools!
84
Apart from its ramming power, Megalodon has something else up its sleeve, even though it really doesn't have arms or wears a coat.
85
Let's take a look at its jaw.
86
Its teeth are about 7 inches long.
87
an absolute record for all known shark species in the world.
88
Megalodon has about 250 of these deadly pointy things arranged in 5 rows.
89
They're also really sharp, which helps it penetrate the thick skin of big animals like whales.
90
Megalodon's jaws are 6.5 feet wide, and it has one of the strongest bites of any animal on the planet.
91
Not only are Are they super dangerous?
92
Megalodon's teeth are also really valuable.
93
One of these ancient incisors was once found in Western Australia.
94
The location where it was dug up was kept secret, but this didn't stop intruders from stealing it.
95
It's probably in someone's private collection by now, and sadly, scientists missed the chance to learn something new about Megalodon.
96
Titanoboa also has a mean set of teeth.
97
They're thin and pointed like needles.
98
They bend inwards in the snake's jaw like fishing hooks.
99
This little feature helps Titanoboa get a grip on its prey and prevent the slightest chance of it running or swimming away.
100
If the animal tries to pull itself free, it will only hurt itself even more.
101
And remember that Titanoboa is incredibly agile, so it can strike with that bite at an incredible speed.
102
Now it's time for the fight itself!
103
but never swims in the open sea.
104
But here Megalodon has gotten lost and ended up in a shallow swampy area off the coast of Colombia.
105
In water like this, Megalodon finds it even harder to move around.
106
It could bite Titanoboa just once and the fight would be over.
107
But because the shark moves so much slower than the snake, for now, he doesn't get the chance to snap those enormous jaws.
108
Titanoboa starts attacking Megalodon, but it can't do much damage to that thick skin with its sharp but very short teeth.
109
Eventually, Megalodon gets its chance and ends the fight with a single bite.
110
It turns out that those huge teeth were what really mattered in this competition.
111
Chew on that for a while.
112
That's 3 to 2 and a victory to the giant shark!

¿Qué es la Técnica de Shadowing?
Shadowing es una técnica de aprendizaje de idiomas respaldada por la ciencia, desarrollada originalmente para la formación de intérpretes profesionales y popularizada por el políglota Dr. Alexander Arguelles. El método es simple pero poderoso: escuchas audio en inglés nativo y lo repites en voz alta de inmediato, como una sombra que sigue al hablante con solo 1-2 segundos de retraso. A diferencia de la escucha pasiva o los ejercicios de gramática, el shadowing obliga a tu cerebro y músculos de la boca a procesar y reproducir simultáneamente patrones de habla reales. Las investigaciones muestran que mejora significativamente la precisión de la pronunciación, la entonación, el ritmo, el habla conectada, la comprensión auditiva y la fluidez al hablar, convirtiéndola en una de las metodologías más efectivas para la preparación del IELTS Speaking y la comunicación en inglés en el mundo real.
