Shadowing Practice: Why Does the OCEAN Get Creepier the Deeper You Go? - Learn English Speaking with Video
Ders oluşturuluyor...
1
The ocean covers 71% of the planet.
2
Fewer people have stood at the bottom of the ocean than have walked on the moon.
3
We've mapped Mars in higher resolution than the ocean floor.
4
And the reason isn't budget or interest.
5
It's that space is genuinely easier to reach.
6
The pressure at the bottom would crush a submarine like a tin can.
7
The darkness is total.
8
The cold is near freezing.
9
And the things living there look like nothing that should exist on Earth.
10
The ocean has five layers.
11
The deeper you go, the less it resembles a place life should survive.
12
The top 200 meters is the sunlight zone.
13
This is the ocean you know.
14
Coral reefs, dolphins, tuna, sea turtles.
15
Phytoplankton here produce roughly half of all the oxygen on Earth.
16
Every second breath you take came from this layer.
17
Almost all marine life lives here.
18
Below 200 meters, sunlight stops.
19
And so does everything familiar.
20
From 200 to 1000 meters is the twilight zone.
21
1% of surface light reaches this depth, enough to see shapes and shadows.
22
Not enough for plants.
23
Pressure climbs to around 100 atmospheres and creatures start getting strange.
24
This is where the Barrelife fish lives.
25
Its head is completely transparent, a dome of clear fluid you can see straight through.
26
Inside, two barrel-shaped eyes rotate inside its own skull, pointing upward through its forehead to spot prey silhouetted against the faint light above.
27
When scientists first caught specimens in nets, they assumed the transparent heads had been damaged.
28
In 2004, researchers at the Monterey Bay Aquarium Research Institute filmed one alive and confirmed the transparency was completely natural.
29
This zone also hosts the largest daily animal migration on Earth.
30
Billions of creatures, fish, squid, jellyfish, rise toward the surface every night to feed, then descend at dawn.
31
Every ocean, every night, simultaneously, invisible to almost everyone alive.
32
At around 900 meters, the vampire squid waits.
33
Despite the name, it doesn't drink blood.
34
It has the largest eyes relative to body size of any animal on Earth.
35
It survives in oxygen levels as low as 3% of surface concentrations, conditions lethal to almost anything else.
36
When threatened, it turns itself inside out, wrapping webbed arms around its body like a cloak,
37
and fires bioluminescent mucus from its arm tips as glowing decoys into the darkness.
38
Below 1000 meters is the midnight zone, down to 4000 meters.
39
No sunlight.
40
Complete darkness.
41
Pressure between 100 and 400 atmospheres.
42
Temperature near freezing.
43
No plants.
44
The only food is marine snow.
45
Dead organisms drifting down from above.
46
The only consistent food source for an enormous amount of life.
47
Nearly 90% of creatures here produce their own light.
48
The dragonfish has a jet black body making it invisible.
49
But it produces and detects red light.
50
A wavelength almost nothing at this depth can see.
51
Deep Sea biologist Edith Witter, who received a MacArthur Fellowship for her bioluminescence research, described it as one of the most sophisticated stealth systems in the animal kingdom.
52
It hunts using a beam its prey cannot perceive.
53
The goblin shark has been here unchanged for 125 million years.
54
It detects electrical fields from other animals through sensors covering its snout.
55
When prey is close, its jaw fires forward like a slingshot, extending 9% of its body length in milliseconds.
56
It doesn't need speed, just proximity.
57
Then there is the anglerfish.
58
The female hangs a bioluminescent lure from her forehead in complete darkness.
59
A small fish approaches, the jaws close, her body expands to swallow prey twice her size, but the mating is what stops people.
60
The male bites into her skin and never lets go.
61
His body fuses to hers, his organs dissolve.
62
He loses his eyes, his fins, his independence, becoming a permanent reproductive attachment.
63
Evolutionary biologist Theodore Peach, at the University of Washington, documented females with six fused males attached simultaneously.
64
What started as a creature becomes part of another one.
65
From 4,000 to 6,000 meters is the abyssal zone.
66
83% of the ocean floor, the largest habitat on Earth, almost entirely unknown.
67
At around 4,000 meters, the water crosses the carbonate compensation depth depth.
68
Below this line, calcium carbonate dissolves so aggressively that shelled creatures virtually vanish.
69
The water literally dissolves their protective armor.
70
The few exceptions use specialized organic coatings or aluminium in their exoskeletons just to hold together.
71
Everything else is soft, gelatinous, built from water, the only structure that survives.
72
Giant isopods roam here, resembling wood lice the size of footballs.
73
They endure years without food, waiting until a whale carcass sinks from above.
74
They strip it to nothing, then return to stillness.
75
Hydrothermal vents split open where tectonic plates pull apart, releasing water above 400 degrees Celsius.
76
Around them, entire ecosystems exist with no sunlight at all.
77
Tube worms two meters long.
78
Ghost white crabs.
79
Shrimp detecting infrared from the vents.
80
These organisms convert chemicals rather than light into energy.
81
Life without a sun, which quietly changes the question of where else in the universe life might exist.
82
In 2024, the Ocean Census, a global initiative to catalog new deep-sea species, sent expeditions to remote Pacific ridges and trenches near New Zealand.
83
What came back included a creature resembling a glowing red sea tomato with no identifiable relatives, and a new species of coral that feeds on flesh.
84
These weren't found in unexplored abyss.
85
They were found on the edges of the already mapped territory, which raises an obvious question about everything beyond it.
86
The deeper we explore the oceans, the stranger life becomes.
87
But here's the thing.
88
Some of the most fascinating ecosystems on Earth are also among the most vulnerable.
89
But it can feel impossible to make a difference when it comes to protecting oceans and the life inside them.
90
The scale of the problem is overwhelming, and there's only so much you can do as an individual.
91
But as a group, as a community, we can make a tremendous difference.
92
That's one reason I like what Planet Wild is doing.
93
PlantWild is a community of more than 25,000 people, including myself, funding real conservation missions around the world,
94
from protecting endangered species to restoring ecosystems and safeguarding marine environments.
95
Think of it like crowdfunding for nature.
96
What I like is that you don't just donate and forget about it.
97
Every month, members receive video updates right here on YouTube showing exactly what's happening on the ground.
98
So instead of wondering whether your contribution made any difference, you actually get to see the results.
99
For example, in one of their latest missions, they used a simple yet effective solution to help fight ocean plastic at the source.
100
I've always been fascinated by the natural world, and the more I learn about it, the more I realize how much there is worth protecting.
101
If you'd like to support real conservation work and help protect the natural world, including the oceans we're talking about today, you can give whatever amount feels right to you.
102
The first 100 people using my code AXEN6 will get their first month paid for by me.
103
Just scan this QR code or click the link in the description.
104
After that, you can cancel any time.
105
If you want to see them in action first, check out their mission video Fighting Ocean Plastic linked below.
106
And now, let's go even deeper.
107
Below 6,000 meters is the Hadal Zone, named after Hades, god of the underworld.
108
It exists only in ocean trenches.
109
The Mariana Trench reaches 10,935 meters at Challenger Deep.
110
Pressure there is 1,086 bar, 8 tons per square inch.
111
People assume the deep ocean is silent.
112
It isn't.
113
Hydrophones dropped into the Mariana Trench recorded a constant eerie acoustic environment.
114
The low rumble of distant earthquakes, whale calls moaning down from miles above, the screech of shifting tectonic plates amplified by the trench walls.
115
Researchers who first listened described it as sounding like a haunted house.
116
The deepest place on Earth is not quiet.
117
The Hadal snailfish is the deepest fish ever filmed.
118
captured at 8,336 meters in a 2023 expedition led by marine biologist Alan Jameson at the University of Western Australia.
119
Translucent.
120
Organs visible through its skin.
121
Cartilage skeleton because bone becomes brittle under this pressure.
122
The apex predator of the Hadal food web.
123
It looks like something biology was not supposed to produce.
124
Below where snailfish survive, amphipods swarm, tiny shrimp-like creatures consuming whatever falls from the world above.
125
Scientists found microplastics in their tissue.
126
Even here, at nearly 11 kilometers below the surface, in the most remote place on Earth, we have already arrived.
127
Researchers also found xenophiophores in Challenger Deep, single-celled organisms growing to the size of a dinner plate.
128
One cell, plate-sized, in total darkness under eight tons of pressure.
129
We have mapped roughly 25% of the ocean floor according to the Seabed 2030 Initiative.
130
The remaining 75% is completely unmapped dark territory.
131
We know more about the surface of the moon.
132
And based on what the explored 25% contains, glowing creatures with no known relatives, fish that fuse their bodies together, coral that eats flesh.
133
The remaining 75% has no obligation to be less strange.
134
Before you go, if you enjoyed learning about the hidden world beneath the ocean, consider checking out Planet Wild.
135
See them in action with their mission-fighting ocean plastic right here.
136
Thanks for watching, and I'll see you in the next one.

Gölgeleme Tekniği Nedir?
Gölgeleme, başlangıçta profesyonel tercüman eğitimi için geliştirilen ve çok dilli Dr. Alexander Arguelles tarafından popüler hale getirilen, bilim destekli bir dil öğrenme tekniğidir. Yöntem basit ama güçlüdür: ana dili İngilizce olan bir sesi dinler ve hemen yüksek sesle tekrar edersiniz — konuşmacıyı 1-2 saniye gecikmeyle takip eden bir gölge gibi. Pasif dinleme veya dilbilgisi alıştırmalarının aksine, gölgeleme beyninizi ve ağız kaslarınızı gerçek konuşma kalıplarını eşzamanlı olarak işlemeye ve yeniden üretmeye zorlar. Araştırmalar, telaffuz doğruluğu, tonlama, ritim, bağlı konuşma, dinleme anlama ve konuşma akıcılığını önemli ölçüde geliştirdiğini göstermektedir — bu da onu IELTS Konuşma hazırlığı ve gerçek dünya İngilizce iletişimi için en etkili yöntemlerden biri yapar.
