Ready?

Inside the stomach of a sperm whale, there's an alarming amount of colossal squid.

And look at this thing, it's huge!

And scientists think something like 80% of a sperm whale's diet is this gigantic animal.

Which means there's gotta be tons of them in the ocean, right?

How hard could it be to find a live one in its natural habitat?

Based on what we know about sperm whales, we figure these colossal squid primarily live here, deep in the ocean.

To get there, we'll need a special submersible.

Down here, sunlight can't reach.

But wait, all around us, there's snow?

For kilometers in every direction, there's nothing else.

We strain our eyes to see, we're searching and searching, because the ocean is so much bigger than most people think.

An adult colossal squid can be over 9 meters long.

But down here, in our sub, it's like looking for a housefly in an arena with the lights off,

using only your phone's flashlight and the weather's bad.

So yeah, it's not looking great for our expedition.

Hello?

Fortunately, in 2025, 100 years after we first realized the colossal squid existed, we got incredibly lucky.

Researchers caught this footage of a young one, an absolutely unbelievable find, entirely by accident.

Just like this footage of an oarfish, or this genuinely terrifying footage of a big fin squid filmed by oil rig operators.

We have evidence that gigantic, monstrous, beautiful, bizarre animals thrive in the cold depths of our oceans.

But up until now, most of our discoveries have just been right place, right time.

But what if I told you there's another way to discover the giant animals in our deep sea?

And all we need is a drop of water.

If you dive into the ocean searching for life, you want to be prepared with the right tools.

And that depends entirely on how deep you plan to go.

For the first 30 meters or so, you can use scuba gear to dive and look around.

There's plenty of light here, and we spent tons of time studying these places.

But despite that easy access, we still keep finding new species all the time.

Experienced divers can go way farther, all the way down to about here.

But they can't stay there long, so sometimes they leave experiments, like these artificial reefs, to pick up later.

These were recovered in 2025 and unveiled around 20 entirely new species.

But the farther down we go, the harder it gets to explore.

By the time you get here, the pressure would make it feel like your entire body is being squeezed.

So scientists use specialized underwater robots.

Some work autonomously, and then they store data or video that's then retrieved after the dive.

Others are tethered to a ship and send back data almost instantaneously.

These can even have sampling arms, and they're equipped with all these cool different sensors.

But when you turn on the lights down here, the first thing that you see is pieces of scales,

and poop, and dust, and dead animals that drift down from the surface.

This is nicely called marine snow.

It's a really important food source for the animals down here, because sunlight struggles to reach this layer.

We're not seeing much at this point, but the animals that we do see are so cool.

Lots of them are transparent or they glow in the dark.

It's like a whole alien carnival happening down there.

But scientists discovered that there's something very weird happening in this part of the ocean.

During World War II, sailors noticed this mysterious shadow on their sonar.

It looked like the sea floor was only a couple hundred meters below them.

But what was alarming was that it was moving.

Every night this giant shadow would rise several hundred meters, inching closer to the ships, but every day it would drop away again.

We later learned this wasn't the sea floor, and it wasn't some hidden fleet, and it wasn't some giant monster.

It was the world's largest migration.

Billions of tons of animals leaving this dark zone to feed in the upper layer at night.

Every single night it's more biomass moving than like the Great Migration in Africa.

Which means that hidden somewhere in all this empty is actually one of the most crowded places on Earth.

Today we know that this giant shift happens all over the world.

It's so big, it actually churns the water.

And it's really important for the health of our planet.

At the surface, phytoplankton pull carbon dioxide out of the air.

And every night, billions of animals come up from the deep to eat those phytoplankton, bringing all that carbon waste deep into the sea, which speeds up how quickly it's removed from our atmosphere.

Today, we still use sound waves to study this zone.

The frequencies hint that there might be billions of tons of elusive animals down here.

But sound alone can't tell us exactly what kinds of animals.

And there's lots of unknown questions about who's moving, are they moving every night, is it different species?

Some come up earlier, some come up later.

Why do they do that?

We have specialized nets, but many of their soft bodies break apart.

And lots of them just avoid it entirely.

So we try to see them, but the trouble is that lights and motors can scare away animals adapted for dark, silent isolation.

We did find a giant monster down here.

But it took so much work.

In 2012, scientists used a red LED light, invisible to most animals down here, and removed any motors to reduce noise.

And then they attached a special lure that flashed blue to mimic a certain jellyfish.

They dropped it 700 meters deep. And then...

A giant squid appeared filmed for the first time in its natural habitat.

But that's not a colossal squid.

Giant squid and colossal squid are different.

And this took a lot of engineering, 20 years of data on the whales that eat these giant squids,

over 100 dives and hundreds of hours just waiting to get these few minutes of footage.

That's a huge amount of time, money, and resources for just a few minutes, but we want to go deeper.

It's dark here.

I mean pitch black.

Any trace of light is quickly absorbed.

We're in the largest single habitat on the planet, accounting for 70% of all seawater.

And we know that giant animals like that squid haunt this place because we see the scars left behind on whales.

But what else?

A brand new, monstrous, beautiful species could be lurking right outside our field of view, and we would never know it.

This is a major problem with deep sea ocean exploration so far.

You just gotta get so lucky.

Most of what we see down here are scavengers, but we're still diving.

Now, welcome to the abyss.

It looks like a desolate desert here, with vast plains of mud and minerals, little metal spheres that have gained a lot of attention for deep sea mining recently

but also alarmingly gigantic animals like this 40 centimeter long isopod.

That thing is 16 times bigger than its terrestrial relative.

Or these 30 centimeter long amphipods that are over 10 times larger than their shallow water counterparts.

We still don't fully understand why these animals grow to these enormous sizes down here.

But our best guesses are that larger animals can go longer without eating and have slower metabolisms, which is great for a food-scarce environment.

One of these giant isopods went five years without eating in captivity.

Another is they evolved in isolation, which lets them grow to massive sizes without getting eaten.

100

And the final one is about temperature, because it's freezing down here, 0 to 4 degrees Celsius.

101

Colder water holds more oxygen, and freezing temperatures cause life to move in slow motion, letting cells grow to enormous sizes.

102

You see this in the freezing waters around Antarctica, which results in something called polar gigantism.

103

We think this is what led to the colossal squid and these gigantic sea spiders.

104

Oh my god, the ocean is terrifying.

105

Oh wait, look!

106

The Dumbo octopus!

107

He's so cute!

108

He comes down here sometimes.

109

But we're still going even deeper, into the Hadal Zone.

110

Trenches here are deeper than Mount Everest is tall, and the pressure feels like a hundred elephants standing on your head.

111

And yet, we're still uncovering tons of life.

112

We've gotten really good at improving our tools for exploring the ocean at all levels.

113

But the big point here is, it's often expensive and time-consuming and even dangerous,

114

which is why so much of what's down here is still invisible to us.

115

We needed a new tool.

116

Ideally, a cheaper one.

117

One that can give us a really broad view of our oceans

118

and all of the life here and help us find that fly in the arena.

119

And now we have one.

120

So I'm using this special water sampling kit, but to buy this and all of the equipment

121

that we use from our mics to our cameras to the software that we're going to use to edit this video, I used this.

122

This.

123

This is my real Mercury card.

124

Mercury is the tool that I've used since Puge started to manage our finances.

125

I can prove it to this is the email that I got activating my account right after I published our launch video.

126

January 31st, 2022.

127

So if you love our show, Mercury has genuinely been behind all of our productions.

128

And the reason for that is that it's all just incredibly easy.

129

Opening an account, sending a wire.

130

None of it requires phone calls, paperwork or in-person visits.

131

You don't have to do any mental gymnastics to figure out what you need to do.

132

From the dumb stuff, I mean on my end, like that time that I lost my card and then froze my account and then found my card and unfroze my account,

133

to the smart stuff like figuring out how to plan our finances and how we're going to make this show.

134

It's a financial technology company, not a bank.

135

If you want to learn more about what they do, you can check the link in the description or you can go to mercury.com.

136

Now, back to our story.

137

This little syringe holds traces of thousands of animals.

138

I collected this sample from the Hudson River, so really who knows what's in here?

139

But this is the same thing that scientists are doing in the deep ocean.

140

All the way down through our oceans, life takes many different forms, but they all have something in common.

141

They shed that snow, the feces and mucus and random scales and tissue particles.

142

So they essentially leave behind like little signals of who they are.

143

Sometimes I just get told I just study poop all day, but there's all kinds of junk that's left behind.

144

And we get all the way from bacteria to fish, all the way up to whales and sharks.

145

So if we dip into that water, pull it up and filter it, we can use those little pieces to extract DNA.

146

Environmental DNA.

147

E-DNA.

148

So what can you do with just a little bit of water?

149

You can do two things.

150

The first is, you can chase a specific animal that you already know exists.

151

Go find your fly in the arena.

152

Imagine the ocean is a giant bowl of alphabet soup, and you put your spoon in there and you sample it.

153

But you're only looking for the letter A.

154

Researchers will use short, single-stranded DNA sequences as a sort of magnet.

155

These will ignore all of the other letters in your soup and latch on to only the one that you want.

156

We could say, well, they were here.

157

We know they were here.

158

And we've done this.

159

This is an angel shark.

160

It's critically endangered.

161

And it's also an ambush predator that's really good at hiding.

162

So for years, the only way that we saw them was when they were accidentally scooped up by fishermen, or just luckily spotted by divers.

163

And so for a while we thought they were extinct in this one particular area.

164

But then researchers sampled the water and they found spikes in angel shark DNA.

165

So they sent the divers directly there.

166

And sure enough, they found them.

167

That sort of thing could help us really quickly find and protect and learn more about all kinds of species.

168

It's being used right now to protect this guy and many others.

169

This method can be faster than traditional methods and way less invasive.

170

And speaking of invasive, we can also use it to identify where invasive species are.

171

If one shows up in a port or in an area where it's not supposed to be, a dive team can really quickly go in and remove them.

172

But what about searching the deep ocean for animals that we know are there, like the colossal squid?

173

We are actually doing that right now in Antarctica.

174

There's a group from New Zealand trying to take samples, and that's our goal is to try

175

and identify all of the cephalopods in the samples

176

and trying to actually see the colossal squid this could be so helpful compared to the luck that we need now.

177

If you're sending a person out to look, they have to be there right at the right time.

178

And so this is another way for us to sort of look backwards in time and say, well, was it here a day ago or two days ago?

179

With enough sampling, there's a future where eDNA could tell us, hey, there's a lot of colossal squid DNA right here all the time,

180

which could let us create heat maps of the animal's range.

181

And it's not impossible to imagine a future where it doesn't

182

take 20 years of whale studies to find a giant squid or a hundred years of just waiting for a lucky break.

183

That is by itself incredible.

184

But here's what I find most huge if true.

185

What if we don't need to know who we're looking for?

186

This is the second thing that you can do.

187

You can hunt for the unknown.

188

You remember this migration?

189

Well, if we know that something is there, There's a good chance that eDNA can tell us who it is and at what times.

190

So during the day, researchers go out

191

and they collect liters of water from the surface

192

and the Twilight Zone area to catch traces of hundreds of species at once.

193

And instead of searching for one specific letter in that alphabet soup, they use something more universal, like, find me all the vowels.

194

And this will flag a bunch of species and then sort them based on the differences in their genes.

195

And later, scientists can go back out and repeat the same process at those locations.

196

So then, if you look at the changes in the DNA samples during the day versus the night, suddenly we have a much clearer picture of who is migrating at what times.

197

And we're doing this hunt for the unknown in the deep sea as well.

198

For us biodiversity scientists, it's the last frontier of exploration.

199

What she found with just water was incredible.

200

A world that we'd never seen with our eyes.

201

We're seeing that there is hot spots of biodiversity

202

and we're detecting these amazing creatures that no one's really seen before, recorded before.

203

A shark that we've only seen a handful of times.

204

Giant squid.

205

Even one animal that we so rarely see we once thought it was entirely extinct.

206

All detected with just water.

207

It's a really, really proof of concept that we can detect really small things in these huge, huge kilometer scales of water.

208

But most exciting to me is when researchers first sampled this area of the abyssal plain.

209

What they found was shocking.

210

You are never gonna see the ocean the same way because of the DNA that came back, 90% of it was unknown.

211

90% they call it dark taxa.

212

We think there are over 2 million different marine species in our oceans.

213

And estimates say that we have documented less than 10%.

214

When we sample water and sequence DNA, we still have to compare that to the databases to find out what it is.

215

But since we don't have the genome for nearly 90% of life in our oceans, a lot of it comes back unknown.

216

Especially in the deep.

217

These might be species that we know about but never genomed.

218

Or it could be something entirely new.

219

Researchers are starting to use machine learning and AI to help fill in those gaps.

220

And the hope is that this could take dark taxa and group it into similar groups.

221

So you could start to say, this unknown animal kind of looks like this one that we do know.

222

We're trying to see like what is like the other.

223

This looks like squid.

224

Is it squid?

225

But to do that, you need data.

226

So that's the true new frontier of ocean discovery.

227

Right now, we're in a big race to sequence our oceans.

228

And the cool thing is we can preserve these eDNA samples and run them again years later with new information.

229

For now, it's a bit of a black box.

230

And that's okay.

231

Because unlike our ROVs where we can only guess that something is lurking behind us, eDNA is telling us, hey, something is here.

232

We just might not know what yet.

233

That's not to say that this is easy.

234

No, this is hard.

235

For one thing, some animals shed more than others.

236

DNA degrades really quickly in shallow waters.

237

In the deep, it stays longer, but it's harder to collect.

238

It's complicated.

239

But the need to go deeper, to learn more, is more urgent than ever.

240

Our planet's biggest ecosystem is changing faster than we can understand it.

241

But fortunately, so is our technology to learn more.

242

Because eDNA doesn't just give us a glimpse at what might be hiding.

243

It also gives us a baseline for the health of our oceans.

244

It's sort of like a totally different type of medical test for the environment that we can start to look at.

245

So we can show it to the world and show them

246

that these are really exciting habitats that are worth us caring about.

247

And what's really cool is that anybody can be involved.

248

They ask for samples from all over the world.

249

I'm going to send off my sample and see what we find.

250

As it gets better and as we put more effort and time into this, it's just going to explode and our applications in the deep sea are...

251

We haven't even scratched the surface of what we can do yet.

252

But as we continue to learn more,

253

we'll find new tech and new life and new ghosts in the deep calling for us to go find them.

FOR YOU

為什麼要通過這個影片練習口語？

看YouTube學英語是一個非常有效的學習方式。通過觀看“巨型烏賊的新獵手”這段影片，學習者可以在探索海洋生物的同時練習英語口語。這段影片講述了科學家們如何研究巨型烏賊及其棲息地，帶給觀眾不只是科學知識的涵養，同時也增強了他們對自然界的好奇心。在口語練習中，學習者可以模仿影片講述者的發音和語調，提高英語口語表達能力。通過英語影子跟讀，學習者可以自信地與他人進行交流。

語法與表達在語境中的應用

在影片中，講述者使用了一些關鍵的語法結構，以下是幾個例子：

使用“there is/there are”結構：例如“there's an alarming amount of colossal squid.”這種結構幫助描述特定情況，可以用於對任何事物的簡單描述。
動詞不定式：短語“to get there”展示了目的和方向，學習者可以在自己的句子中靈活使用。
條件句：句子“if you dive into the ocean searching for life”引導了條件句的使用，幫助學習者理解如何表達假設和條件。
現在進行時：短語“we're searching and searching”強調了動作的持續性，適合用於日常對話。

常見發音陷阱

在影片中，有一些詞彙和發音可能會讓英語學習者感到困惑：

colossal：這個詞的發音較為複雜，注意重音位置，通常在第二個音節上。
squid：海洋生物的名稱，有時由於其含糊的母音，發音可能不清晰，需要反覆練習。
autonomously：這個詞較長，通常學習者可能會在發音上錯誤分割，建議進行慢速朗讀以掌握其節奏。

通過練習這些發音，學習者可以改善發音的準確性，為與他人進行流利的英語對話打下基礎。多次使用英語影子跟讀和相關的shadow speech練習，可以有效提升口語能力。

影片中的語法

說話人最常用的結構，並附上影片中的原話：

結構	影片中的用法
現在完成時 have/has + 過去分詞 — 過去發生但與現在仍有關聯的事	have just been · have specialized · have gained
被動語態 be + 過去分詞 — 強調發生了什麼，而不是誰做的	were recovered · being squeezed · are tethered

什麼是跟讀法？

跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧，最初開發用於專業口譯員的培訓，並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大：您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同，跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性，語調，節奏，連讀，聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
