6
00:00:10,655 --> 00:00:13,103
Researchers believe
these sharks gather here

7
00:00:13,206 --> 00:00:15,551
to feed on the island's
seal population.

8
00:00:16,137 --> 00:00:18,000
[man speaking over radio]

9
00:00:18,896 --> 00:00:20,034
[narrator] But recently,

10
00:00:20,137 --> 00:00:22,137
incredible new evidence
has surfaced

11
00:00:22,241 --> 00:00:25,482
about a battle royale
brewing beneath the waves.

12
00:00:27,689 --> 00:00:31,206
[Tristan]
Mexican scientists here
have started to see evidence

13
00:00:31,310 --> 00:00:33,896
of scarring on some of these
big white sharks,

14
00:00:34,000 --> 00:00:36,482
suggesting that they're having
these titanic battles

15
00:00:36,586 --> 00:00:39,103
with one of the most
mysterious creatures
on the planet...

16
00:00:40,896 --> 00:00:41,965
the giant squid.

17
00:00:45,655 --> 00:00:47,724
You just imagine
what that would look like.

18
00:00:47,827 --> 00:00:50,206
We've got the white shark
in one corner.

19
00:00:50,310 --> 00:00:53,896
Power, speed,
slicing triangular teeth.

20
00:00:54,000 --> 00:00:56,413
And in the other corner
we've got massive, big,

21
00:00:56,517 --> 00:00:58,379
and huge arms
to engulf something.

22
00:00:58,482 --> 00:01:00,206
Completely different
tools to be

23
00:01:00,310 --> 00:01:03,655
the most formidable predators
in the deep.

24
00:01:03,758 --> 00:01:06,275
[narrator] Now, a team
of researchers are
on a mission...

25
00:01:06,379 --> 00:01:08,103
[Tristan] Kraken,
here we come.

26
00:01:08,206 --> 00:01:10,896
...to discover how these
titans clash in the abyss...

27
00:01:12,103 --> 00:01:13,103
[Lily] Look at that shark
zoning in

28
00:01:13,206 --> 00:01:14,517
right on the squid bait.

29
00:01:14,620 --> 00:01:15,724
[Tristan] Amazing!

30
00:01:15,827 --> 00:01:17,275
[narrator]
...and if a creature the size

31
00:01:17,379 --> 00:01:18,793
of the mythical kraken

32
00:01:18,896 --> 00:01:20,689
could beat a great white,

33
00:01:20,793 --> 00:01:22,724
in the ultimate
deep sea showdown.

34
00:01:23,379 --> 00:01:24,517
[Lily] Shark coming in hot!

35
00:01:27,724 --> 00:01:28,551
[chomps]

36
00:01:35,241 --> 00:01:36,620
[Tristan] We've come
to Guadalupe island

37
00:01:36,724 --> 00:01:39,275
to explore
a fascinating phenomenon.

38
00:01:39,379 --> 00:01:41,310
There was a study
that came out last year

39
00:01:41,413 --> 00:01:42,931
that showed photographs

40
00:01:43,034 --> 00:01:43,862
of white sharks,

41
00:01:43,965 --> 00:01:46,206
with these suction marks
on them,

42
00:01:46,310 --> 00:01:49,310
suggesting that they are
having these titanic battles

43
00:01:49,413 --> 00:01:50,620
with squid in the depths.

44
00:01:57,896 --> 00:02:01,103
It's hard to tell exactly
which species of squid it is

45
00:02:01,206 --> 00:02:02,413
that's making the scarrings,

46
00:02:02,517 --> 00:02:05,862
but the patterns,
the sizes of the suction cups,

47
00:02:05,965 --> 00:02:07,517
means it could only be

48
00:02:07,620 --> 00:02:09,793
three of the biggest squid
that exist.

49
00:02:11,068 --> 00:02:13,413
[narrator] There are three
large species of squid

50
00:02:13,517 --> 00:02:15,413
lurking around
Guadalupe Island.

51
00:02:16,793 --> 00:02:18,241
All of them are elusive

52
00:02:18,344 --> 00:02:20,275
and favor the hostile
environments

53
00:02:20,379 --> 00:02:21,620
of the extreme deep.

54
00:02:22,931 --> 00:02:24,896
First is the Humboldt,

55
00:02:25,000 --> 00:02:27,689
which are also known
as Red Devils,

56
00:02:27,793 --> 00:02:29,689
because of their
aggressive behavior.

57
00:02:31,310 --> 00:02:34,896
Then, there's the extremely
rare octopus squid,

58
00:02:35,000 --> 00:02:39,172
which can clock in
at a length of up to 7 ft.

59
00:02:39,275 --> 00:02:42,551
But the most fearsome
is the giant squid,

60
00:02:42,655 --> 00:02:45,862
a true alien of the deep,
that scientists theorize

61
00:02:45,965 --> 00:02:49,000
can reach lengths
of up to 60 ft. long.

62
00:02:50,034 --> 00:02:52,448
But if legends
are to be believed,

63
00:02:52,551 --> 00:02:55,034
there might be something
even bigger out there.

64
00:02:56,172 --> 00:02:58,551
[Tristan] You hear of these
legendary stories

65
00:02:58,655 --> 00:03:02,758
of these sailors experiencing
this gigantic cephalopod

66
00:03:02,862 --> 00:03:06,551
with huge arms reaching,
like, 40 ft. in length.

67
00:03:08,206 --> 00:03:09,896
They call it the kraken.

68
00:03:16,068 --> 00:03:17,172
[narrator] The myth
of the kraken

69
00:03:17,275 --> 00:03:19,000
dates back centuries,

70
00:03:19,103 --> 00:03:21,068
but researchers know
that most myths

71
00:03:21,172 --> 00:03:23,000
have a kernel
of truth in them.

72
00:03:23,103 --> 00:03:25,482
And modern scientists theorize

73
00:03:25,586 --> 00:03:27,896
that the kraken
was probably inspired

74
00:03:28,000 --> 00:03:29,793
by large squid species

75
00:03:29,896 --> 00:03:31,931
like the ones
great whites are encountering

76
00:03:32,034 --> 00:03:33,137
around Guadalupe.

77
00:03:33,862 --> 00:03:35,275
[Tristan] Today, we know

78
00:03:35,379 --> 00:03:37,448
that squid can get up
to huge sizes,

79
00:03:37,551 --> 00:03:39,103
so if you imagine
one of these animals,

80
00:03:39,206 --> 00:03:40,896
coming up
to the surface overnight,

81
00:03:41,000 --> 00:03:42,827
it could easily be mistaken

82
00:03:42,931 --> 00:03:45,000
for some sort of
bizarre sea monster.

83
00:03:46,689 --> 00:03:48,793
We know that
there's these crazy battles

84
00:03:48,896 --> 00:03:51,241
of giant squid
and white sharks here

85
00:03:51,344 --> 00:03:52,655
at Guadalupe Island.

86
00:03:52,758 --> 00:03:55,000
And, what I'm hoping to do
is gain a glimpse into that...

87
00:03:55,689 --> 00:03:56,551
epic battle.

88
00:03:56,655 --> 00:03:58,172
[bell dings]

89
00:03:58,275 --> 00:04:00,689
[narrator] In one corner,
the kraken,

90
00:04:00,793 --> 00:04:02,965
the giant squid of Guadalupe.

91
00:04:04,275 --> 00:04:06,000
He's got the reach advantage

92
00:04:06,103 --> 00:04:08,379
and much of it comes
from the eight tentacles.

93
00:04:09,310 --> 00:04:11,482
Each of these fleshy whips,

94
00:04:11,586 --> 00:04:14,241
is lined with
hundreds of suckers,

95
00:04:14,344 --> 00:04:15,758
and each of those suckers

96
00:04:15,862 --> 00:04:19,724
is lined with thousands
of tiny sharp teeth

97
00:04:19,827 --> 00:04:22,379
that can tear
and lacerate flesh.

98
00:04:23,275 --> 00:04:24,827
But that's not all.

99
00:04:24,931 --> 00:04:27,310
Their mouths
are razor-sharp beaks

100
00:04:27,413 --> 00:04:29,896
that can stab
and cut their opponents.

101
00:04:30,620 --> 00:04:31,758
[bell dings]

102
00:04:31,862 --> 00:04:34,655
[narrator]
In the other corner,
the white shark.

103
00:04:34,758 --> 00:04:39,413
Jaws... they can reach lengths
of over 20 ft. long.

104
00:04:39,517 --> 00:04:42,931
And when it comes to weight,
they pack much more punch.

105
00:04:43,793 --> 00:04:45,965
A mature female white shark

106
00:04:46,068 --> 00:04:48,931
can weigh close to 5000 lbs.

107
00:04:50,103 --> 00:04:53,241
Their primary weapon
is a mouth lined

108
00:04:53,344 --> 00:04:57,517
with dozens of huge
razor-sharp triangular teeth

109
00:04:57,620 --> 00:04:59,620
designed to decimate
their prey.

110
00:05:05,827 --> 00:05:08,689
[Tristan] When we put
these two fearsome predators

111
00:05:08,793 --> 00:05:09,827
against each other,

112
00:05:09,931 --> 00:05:12,103
we've got completely
different traits

113
00:05:12,206 --> 00:05:13,448
that they can fight with,

114
00:05:13,551 --> 00:05:15,241
and tools to be

115
00:05:15,344 --> 00:05:18,482
the most formidable predators
in the deep.

116
00:05:18,586 --> 00:05:21,482
[narrator] Because these large
squid species are so elusive,

117
00:05:22,206 --> 00:05:23,655
it's extremely difficult

118
00:05:23,758 --> 00:05:26,310
for behavioral ecologists
like Tristan,

119
00:05:26,413 --> 00:05:27,896
to observe how white sharks

120
00:05:28,000 --> 00:05:29,724
behave around them
in the wild.

121
00:05:30,896 --> 00:05:32,758
[Tristan] Squid is some
of the most mysterious

122
00:05:32,862 --> 00:05:33,827
creatures on the planet,

123
00:05:33,931 --> 00:05:35,448
particularly some
of the bigger species

124
00:05:35,551 --> 00:05:36,655
like the giant squid.

125
00:05:36,758 --> 00:05:39,137
It's gonna be really tricky
to get an insight

126
00:05:39,241 --> 00:05:41,034
into the behavior
of that species.

127
00:05:41,137 --> 00:05:42,103
But the white shark,

128
00:05:42,206 --> 00:05:44,103
by running
these different experiments,

129
00:05:44,206 --> 00:05:46,965
by putting different
novel stimuli in the water,

130
00:05:47,068 --> 00:05:49,103
hopefully we can learn
more about the behavior

131
00:05:49,206 --> 00:05:51,275
of the white sharks when they
come across an adversary

132
00:05:51,379 --> 00:05:52,896
like a squid.

133
00:05:53,000 --> 00:05:54,965
However, even though
we're gonna be observing

134
00:05:55,068 --> 00:05:57,241
the behavior of
the white sharks,

135
00:05:57,344 --> 00:05:59,586
one goal that we'll have
throughout the trip

136
00:05:59,689 --> 00:06:01,758
is to try and get
a unique encounter

137
00:06:01,862 --> 00:06:02,896
with a big squid.

138
00:06:05,931 --> 00:06:07,241
[whooshes]

139
00:06:09,586 --> 00:06:10,793
[Tristan]
I've brought my friend, Lily,

140
00:06:10,896 --> 00:06:12,344
she has a background
in neuroscience

141
00:06:12,448 --> 00:06:13,931
and has worked
with squid before.

142
00:06:14,034 --> 00:06:15,620
[Lily] My name
is Lily Rios-Brady,

143
00:06:15,724 --> 00:06:17,724
and I have a master's
in marine science.

144
00:06:17,827 --> 00:06:19,448
My background,
when it comes to squid,

145
00:06:19,551 --> 00:06:22,310
we were looking to see if
membrane proteins [chuckles]

146
00:06:22,413 --> 00:06:25,206
synthesize locally
within the axon.

147
00:06:26,862 --> 00:06:27,758
Yeah, I know.

148
00:06:27,862 --> 00:06:29,758
[both laughing]

149
00:06:31,448 --> 00:06:32,551
[narrator] Even though
the researchers

150
00:06:32,655 --> 00:06:34,344
can't place a white shark

151
00:06:34,448 --> 00:06:36,551
in an arena
with a giant squid,

152
00:06:36,655 --> 00:06:39,344
they can put them in one
that simulates their presence

153
00:06:39,448 --> 00:06:40,448
with scent.

154
00:06:41,965 --> 00:06:43,862
[Tristan]
So, it's a simple choice test

155
00:06:43,965 --> 00:06:47,379
to see if these sharks
show any kind of preference,

156
00:06:47,482 --> 00:06:51,034
or different behavior
towards squid versus tuna.

157
00:06:51,137 --> 00:06:52,137
This frame right here,

158
00:06:52,241 --> 00:06:53,655
I'll load it up with some tuna

159
00:06:53,758 --> 00:06:55,034
and the frame behind me
will have squid.

160
00:06:55,137 --> 00:06:57,137
It's marked with black tape
on the side,

161
00:06:57,241 --> 00:06:58,655
so you know
which one is which.

162
00:06:58,758 --> 00:07:01,206
And if we have them
either side,

163
00:07:01,310 --> 00:07:02,758
-of a cage in the middle...
-Yep.

164
00:07:02,862 --> 00:07:05,172
...then I can see
if they're cueing in

165
00:07:05,275 --> 00:07:06,862
on the squid or tuna.

166
00:07:06,965 --> 00:07:08,206
Let's do it.

167
00:07:08,310 --> 00:07:10,517
[Tristan] By seeing how they
react to the smell of squid,

168
00:07:10,620 --> 00:07:12,793
we can learn more
about how they might

169
00:07:12,896 --> 00:07:15,068
approach the animal,
how they might attack it.

170
00:07:22,137 --> 00:07:24,551
[narrator] In addition
to the big test rigs,

171
00:07:24,655 --> 00:07:27,206
Lily deploys
a live feed camera,

172
00:07:27,310 --> 00:07:28,896
so she can keep an eye out

173
00:07:29,000 --> 00:07:30,413
for sharks from the surface.

174
00:07:39,206 --> 00:07:41,241
Tristan and cameraman
Mark Romanov,

175
00:07:41,827 --> 00:07:43,344
descend to 70 ft.

176
00:07:45,206 --> 00:07:46,172
positioning themselves

177
00:07:46,275 --> 00:07:49,931
right in the center
of the big test arena.

178
00:07:51,689 --> 00:07:54,000
[Tristan speaking]

179
00:08:02,034 --> 00:08:03,827

[Tristan speaking]

181
00:08:17,275 --> 00:08:19,172
All right, Tristan,
we got the live feed working.

182
00:08:19,275 --> 00:08:22,103
I can see you and Mark
down there with the BRUV.

183
00:08:22,206 --> 00:08:24,000
[Tristan speaking]

184
00:08:31,482 --> 00:08:33,206

00:08:36,103 --> 00:08:37,344
[Tristan speaking]

186
00:08:39,551 --> 00:08:40,827
[exhaling]

187
00:09:09,931 --> 00:09:13,724
[narrator] Moray eels
are a carnivorous species.

188
00:09:13,827 --> 00:09:17,034
And their bodies are covered
with a mucous layer.

189
00:09:17,137 --> 00:09:21,000
In some species,
this mucus is toxic.

190
00:09:21,103 --> 00:09:22,275
[Tristan speaking]

191
00:09:43,724 --> 00:09:44,620
[water splashes]

192
00:09:44,724 --> 00:09:46,655
Holy [bleep]! Holy [bleep]!

193
00:09:46,758 --> 00:09:48,310
[Lily speaking]

194
00:09:54,586 --> 00:09:55,793
[Lily] There's a huge shark
up here.

195
00:09:55,896 --> 00:09:57,241
It just came in for the bait.

196
00:09:58,000 --> 00:09:59,137
[Tristan speaking]

197
00:10:34,275 --> 00:10:35,448
[Lily speaking]

198
00:10:38,172 --> 00:10:39,413
[Tristan speaking]

199
00:11:02,034 --> 00:11:04,793
[narrator] The cautious
behavior of the white sharks

200
00:11:04,896 --> 00:11:07,551
could be a sign that
they recognize the presence

201
00:11:07,655 --> 00:11:08,965
of a deadly foe.

202
00:11:11,551 --> 00:11:12,724
[Tristan speaking]

203
00:11:31,034 --> 00:11:32,275
[Lily speaking]

204
00:11:35,206 --> 00:11:37,965
[narrator] Tristan and Mark
are suddenly surrounded...

205
00:11:39,827 --> 00:11:42,862
by big and powerful,
great white sharks.

206
00:11:43,413 --> 00:11:44,689
[Tristan speaking]

207
00:11:48,344 --> 00:11:50,896
[narrator] And they're growing
more and more aggressive,

208
00:11:51,000 --> 00:11:52,965
in the presence
of the squid's scent.

209
00:11:53,620 --> 00:11:54,862
[Tristan speaking]

210
00:11:59,724 --> 00:12:01,034

[Tristan exclaiming]

214
00:12:19,551 --> 00:12:22,137
[narrator] As the sharks
circle the squid bait,

215
00:12:22,241 --> 00:12:24,482
they become
more and more aggressive.

216
00:12:27,620 --> 00:12:28,896
[Tristan speaking]

217
00:12:40,241 --> 00:12:41,413

[Lily speaking]

220
00:13:02,448 --> 00:13:03,620
[Tristan speaking]

221
00:13:15,620 --> 00:13:18,896
[narrator] This massive female
displays battle scars,

222
00:13:19,896 --> 00:13:22,344
similar to those
that scientists believe

223
00:13:22,448 --> 00:13:25,620
other great whites received
from giant squid.

224
00:13:28,034 --> 00:13:30,620
And along with other sharks
in the area,

225
00:13:30,724 --> 00:13:32,379
she's showing a clear interest

226
00:13:33,103 --> 00:13:34,758
in the squid bait rig.

227
00:13:35,482 --> 00:13:36,758
[Tristan speaking]

228
00:13:58,137 --> 00:14:00,379
All right, sounds good.
We'll pull you up right now.

229
00:14:00,482 --> 00:14:02,000
-[man 1] We coming up?
-[man 2] Yeah.

230
00:14:12,448 --> 00:14:13,689
[Tristan] Whoo!

231
00:14:13,793 --> 00:14:15,172
Tristan, how was it
down there?

232
00:14:15,275 --> 00:14:16,827
That looked crazy!

233
00:14:16,931 --> 00:14:18,689
-Still kinda like...
-[Lily chuckles]

234
00:14:18,793 --> 00:14:20,275
I mean it's...
it's a combination

235
00:14:20,379 --> 00:14:22,379
of adrenaline, excitement,

236
00:14:22,482 --> 00:14:25,517
and had really aggressive
approaches on the cage.

237
00:14:25,620 --> 00:14:26,793
There was bites and bumps...

238
00:14:26,896 --> 00:14:29,379
I could see a little bit of
that action on the live feed.

239
00:14:29,482 --> 00:14:31,551
-All the action...
-[Lily] Was on the right side.

240
00:14:31,655 --> 00:14:32,758
...was on the squid side.

241
00:14:32,862 --> 00:14:34,206
Certainly a great start.

242
00:14:34,310 --> 00:14:36,758
-[Lily] Oh, definitely.
-Whoo! Need to get
a hot chocolate.

243
00:14:36,862 --> 00:14:38,689
[Lily laughs]

244
00:14:38,793 --> 00:14:41,034
[narrator] The first test
is demonstrated.

245
00:14:41,137 --> 00:14:43,206
The Guadalupe's white sharks

246
00:14:43,310 --> 00:14:46,068
are more interested
in the scent of squid,

247
00:14:46,172 --> 00:14:47,448
than that of other bait.

248
00:14:48,310 --> 00:14:49,275
[thuds]

249
00:14:49,379 --> 00:14:50,758
[Tristan exclaiming]

250
00:14:50,862 --> 00:14:51,793
[metal clanks]

251
00:14:54,862 --> 00:14:57,172
[narrator]
And they were also agitated

252
00:14:57,275 --> 00:14:59,448
and aggressive
in its presence.

253
00:15:01,517 --> 00:15:04,137
This behavior
might be explained

254
00:15:04,241 --> 00:15:06,137
by their past experiences

255
00:15:06,241 --> 00:15:08,482
battling these deadly foes
in the deep.

256
00:15:10,344 --> 00:15:13,172
And it's the team's
first valuable insight

257
00:15:13,275 --> 00:15:17,000
into what happens
when these titans clash.

258
00:15:19,689 --> 00:15:21,724
[Tristan] Um, where are
we thinking the next one?

259
00:15:21,827 --> 00:15:23,689
Up here?
And another one there?

260
00:15:23,793 --> 00:15:25,137
These are just
gonna get chewed up.

261
00:15:25,241 --> 00:15:26,620
[narrator]
Lily and Tristan prepare

262
00:15:26,724 --> 00:15:29,310
for their next
behavioral experiment,

263
00:15:29,413 --> 00:15:32,689
and this one
is all about sight.

264
00:15:32,793 --> 00:15:35,758
[Tristan] We know the squid
can produce light themselves.

265
00:15:35,862 --> 00:15:37,413
They can bio-luminesce.

266
00:15:37,517 --> 00:15:40,482
But do the white sharks
use that to hunt them?

267
00:15:40,586 --> 00:15:42,586
So, we have a camera,

268
00:15:42,689 --> 00:15:44,241
with essentially
these little lights

269
00:15:44,344 --> 00:15:46,758
that mimic
the bioluminescence.

270
00:15:46,862 --> 00:15:47,965
And the idea is to see

271
00:15:48,068 --> 00:15:49,827
whether white sharks react
to those lights.

272
00:15:51,413 --> 00:15:52,931
[seagulls squawking]

273
00:15:53,931 --> 00:15:55,655
I'm not really sure
what we should call it.

274
00:15:55,758 --> 00:15:57,275
-What do you think?
-Um...

275
00:15:57,379 --> 00:15:59,137
-The squid Christmas tree?
-The...

276
00:15:59,241 --> 00:16:00,344
The Squidmas.

277
00:16:00,448 --> 00:16:03,241
-Squidmas. Okay. Right.
-[chuckles]

278
00:16:03,344 --> 00:16:05,206
[narrator] Squid use
bioluminescence

279
00:16:05,310 --> 00:16:07,172
for a variety of reasons,

280
00:16:07,275 --> 00:16:10,379
from communication
to confusing predators.

281
00:16:10,482 --> 00:16:12,827
But Tristan and Lily
want to find out

282
00:16:12,931 --> 00:16:16,137
if it might also make them
a target for white sharks.

283
00:16:19,482 --> 00:16:20,551
Good luck.

284
00:16:23,827 --> 00:16:26,896
[narrator]
In 2014, a lure like this

285
00:16:27,000 --> 00:16:29,206
was used to capture
this incredible footage

286
00:16:29,310 --> 00:16:31,241
of a giant squid

287
00:16:31,344 --> 00:16:33,586
in the depths
of the Gulf of Mexico.

288
00:16:39,413 --> 00:16:42,931
While the deep-drop camera
records in the abyss,

289
00:16:43,034 --> 00:16:46,344
Lily and Tristan will dive
in a surface cage,

290
00:16:46,448 --> 00:16:49,862
while the boat crew deploys
floating LED lures

291
00:16:49,965 --> 00:16:53,103
as additional attractants
for white sharks.

292
00:16:54,344 --> 00:16:57,793
This will also be
Lily's first time in the water

293
00:16:57,896 --> 00:17:00,172
with these
incredible predators.

294
00:17:00,275 --> 00:17:01,793
I've never dove
with white sharks.

295
00:17:01,896 --> 00:17:03,965
So, I'm really excited to see

296
00:17:04,068 --> 00:17:06,000
more of them
and how they behave.

297
00:17:11,172 --> 00:17:12,275

[Tristan speaking]

300
00:17:30,620 --> 00:17:32,068
[narrator] Ctenophora,

301
00:17:32,172 --> 00:17:35,241
more commonly known
as comb jellyfish,

302
00:17:35,344 --> 00:17:37,965
are bioluminescent
sea creatures

303
00:17:38,068 --> 00:17:40,620
that both emit
and detect light.

304
00:17:41,862 --> 00:17:43,000
[Lily speaking]

305
00:17:49,827 --> 00:17:51,000

[Tristan exclaiming]

313
00:19:26,965 --> 00:19:30,172
[narrator] The seal's agility
and speed allows it

314
00:19:30,275 --> 00:19:34,000
to narrowly escape the jaws
of these great whites.

315
00:19:36,517 --> 00:19:38,206
With it fleeing the area,

316
00:19:38,310 --> 00:19:41,827
the predator's attention
turns to something else.

317
00:19:44,344 --> 00:19:45,517
[Lily speaking]

318
00:19:54,482 --> 00:19:55,655

[Tristan speaking]

320
00:20:28,965 --> 00:20:30,931
[narrator] The great white
has displayed interest

321
00:20:31,034 --> 00:20:33,241
not only in the LED lights,

322
00:20:33,344 --> 00:20:36,000
but in the crew's
underwater cameras as well.

323
00:20:37,551 --> 00:20:41,206
This could be a result
of its ampullae of Lorenzini.

324
00:20:41,310 --> 00:20:45,413
Small pores on its nose
that can detect electricity,

325
00:20:45,517 --> 00:20:49,965
just like the bioelectricity
generated by bioluminescents.

326
00:20:54,965 --> 00:20:55,965
[Tristan speaking]

327
00:21:14,758 --> 00:21:17,068
[narrator] The drop camera
has been on the bottom

328
00:21:17,172 --> 00:21:20,896
at 300 ft.,
recording for two hours.

329
00:21:22,034 --> 00:21:23,586

00:22:13,482 --> 00:22:16,793
to light that mimics

[Tristan speaking]

335
00:22:19,068 --> 00:22:22,758
[narrator]
...the researchers witness
something incredible.

336
00:22:23,413 --> 00:22:24,586
[Tristan speaking]

337
00:22:48,034 --> 00:22:49,034
[narrator]
Several great whites

338
00:22:49,137 --> 00:22:50,689
emerge from the depths,

339
00:22:50,793 --> 00:22:53,724
in pursuit of their
deep-drop LED lure.

00:23:27,758 --> 00:23:28,931
[Tristan speaking]

344
00:23:39,689 --> 00:23:40,689
[Lily speaking]

345
00:23:43,000 --> 00:23:45,517
[narrator] The assault
on the deep-drop camera

346
00:23:45,620 --> 00:23:47,172
is further evidence,

347
00:23:47,275 --> 00:23:51,241
that Guadalupe white sharks
hunt squid in the deep,

348
00:23:51,344 --> 00:23:54,586
and that they're attracted
to their bioluminescence.

349
00:23:54,689 --> 00:23:56,517
-[Tristan] Wow! That was cool.
-[Lily chuckling] Whoa!

350
00:23:56,620 --> 00:23:57,931
When the drop cam came up

351
00:23:58,034 --> 00:24:00,068
-you see it
pursuing it, as well.
-Yeah.

352
00:24:00,172 --> 00:24:03,206
Makes me think what the hell
was going on down deep.

353
00:24:04,413 --> 00:24:06,965
[narrator] Analysis of
the deep drop camera

354
00:24:07,068 --> 00:24:11,241
reveals a huge great white
emerging from the abyss

355
00:24:11,344 --> 00:24:13,448
to investigate the LED lure

356
00:24:13,551 --> 00:24:16,241
shortly before the crew
brought it to the surface.

357
00:24:18,034 --> 00:24:21,172
At this depth,
there's very little light

358
00:24:21,275 --> 00:24:23,896
and giant squid
have a clear advantage

359
00:24:24,000 --> 00:24:26,724
when it comes to seeing
in the dark.

360
00:24:29,172 --> 00:24:31,413
And up to ten inches
in diameter,

361
00:24:31,517 --> 00:24:34,758
they have the largest eye
in the animal kingdom.

362
00:24:36,931 --> 00:24:39,344
Their huge
light-gathering pupils

363
00:24:39,448 --> 00:24:41,482
allow them to see in the dark,

364
00:24:41,586 --> 00:24:44,310
with enough resolution
to detect predators

365
00:24:44,413 --> 00:24:46,344
from up to 400 feet away.

366
00:24:48,758 --> 00:24:51,344
The giant squid's
heightened visual sense

367
00:24:51,448 --> 00:24:52,482
makes it challenging

368
00:24:52,586 --> 00:24:54,241
to get close enough
for an attack.

369
00:24:55,551 --> 00:24:56,689
But even if a great white

370
00:24:56,793 --> 00:24:59,241
manages to reach
striking distance,

371
00:24:59,344 --> 00:25:01,413
the cephalopods have another

372
00:25:01,517 --> 00:25:03,793
amazing defensive measure,

373
00:25:03,896 --> 00:25:05,448
jet propulsion.

374
00:25:06,655 --> 00:25:08,034
[Tristan]
Imagine a white shark

375
00:25:08,137 --> 00:25:10,034
trying to hunt a squid.

376
00:25:10,137 --> 00:25:11,551
They got this jet propulsion,

377
00:25:11,655 --> 00:25:13,758
they can move through
the water really quickly,

378
00:25:13,862 --> 00:25:16,172
so the sharks need
as much intelligence

379
00:25:16,275 --> 00:25:18,896
as they do
power and brute force.

380
00:25:19,000 --> 00:25:22,241
[narrator] Squid achieve
these amazing bursts of speed

381
00:25:22,344 --> 00:25:24,482
by filling their mantle
with water,

382
00:25:24,586 --> 00:25:27,413
and then expelling it
through a siphon-like tube

383
00:25:27,517 --> 00:25:29,379
that gets narrower
towards the end.

384
00:25:29,482 --> 00:25:30,586
[whooshes]

385
00:25:30,689 --> 00:25:32,344
It's an incredible adaptation,

386
00:25:32,448 --> 00:25:35,068
but it allows them to become
a very difficult animal

387
00:25:35,172 --> 00:25:36,206
to then predate upon.

388
00:25:39,000 --> 00:25:40,068
[narrator]
To see how the sharks

389
00:25:40,172 --> 00:25:42,551
might overcome
a squid's jet power,

390
00:25:42,655 --> 00:25:45,586
the team sets up an experiment
with throw-baits.

391
00:25:47,965 --> 00:25:49,724
We have a bait
that's on a float,

392
00:25:49,827 --> 00:25:51,862
manned by someone
who can move it.

393
00:25:51,965 --> 00:25:53,586
And so, every time
they go for the bait,

394
00:25:53,689 --> 00:25:55,172
someone's moving it
out of the way.

395
00:25:55,275 --> 00:25:58,000
[narrator] This test
will allow Tristan and Lily,

396
00:25:58,103 --> 00:26:00,068
to observe
how quickly great whites

397
00:26:00,172 --> 00:26:02,413
change their tactics
on the fly

398
00:26:02,517 --> 00:26:05,827
to make a successful attack
on fast-moving prey.

399
00:26:05,931 --> 00:26:08,241
[Tristan] Lily and I are gonna
spend time in a cage

400
00:26:08,344 --> 00:26:11,103
to see how these animals
are attacking a bait

401
00:26:11,206 --> 00:26:13,793
and how they're
learning from experience.

402
00:26:13,896 --> 00:26:14,827
[Lily] All right, let's go.

403
00:26:23,172 --> 00:26:24,379
[Tristan speaking]

404
00:26:35,000 --> 00:26:36,103
[Lily speaking]

405
00:26:39,896 --> 00:26:41,103
[Tristan speaking]

406
00:27:10,241 --> 00:27:12,655
[narrator] The shark makes
a slow deliberate approach

407
00:27:12,758 --> 00:27:15,068
to the tuna,
which doesn't work.

408
00:27:18,793 --> 00:27:20,000
[Tristan speaking]

409
00:27:23,517 --> 00:27:24,689
[Lily speaking]

410
00:27:25,965 --> 00:27:27,172
[Tristan speaking]

411
00:27:37,724 --> 00:27:39,275
[narrator]
On its second attempt,

412
00:27:39,379 --> 00:27:40,758
the shark tries something new,

413
00:27:42,034 --> 00:27:44,034
putting on a sudden
burst of speed,

414
00:27:44,137 --> 00:27:45,862
as it gets close
to its target.

415
00:27:46,793 --> 00:27:48,379
But it's still not enough.

416
00:27:53,551 --> 00:27:54,724
[Tristan speaking]

417
00:27:58,965 --> 00:28:00,896
[narrator]
Like most wild predators,

418
00:28:01,000 --> 00:28:03,965
great whites conserve energy
whenever possible.

419
00:28:04,068 --> 00:28:07,344
But to catch this bait,
it's becoming clear

420
00:28:07,448 --> 00:28:09,275
that it needs
to take advantage

421
00:28:09,379 --> 00:28:11,103
of its incredible speed.

422
00:28:11,206 --> 00:28:12,413
[Tristan speaking]

423
00:28:39,724 --> 00:28:41,103
[narrator] On the third try,

424
00:28:41,206 --> 00:28:44,275
the shark makes a faster
and more persistent approach

425
00:28:44,379 --> 00:28:46,517
snapping several times
at the bait.

426
00:28:49,586 --> 00:28:50,793
[Tristan speaking]

427
00:28:56,620 --> 00:28:58,172
[narrator] But against
a highly evolved

428
00:28:58,275 --> 00:29:00,931
and intelligent target
like giant squid,

429
00:29:01,034 --> 00:29:04,413
strategy is just as important
as power and speed.

430
00:29:06,655 --> 00:29:07,931
[Tristan speaking]

431
00:29:26,517 --> 00:29:27,517
[Tristan speaking]

432
00:29:31,000 --> 00:29:32,862
[narrator] Having failed
at obtaining the bait

433
00:29:32,965 --> 00:29:34,793
with horizontal approaches,

434
00:29:34,896 --> 00:29:38,206
this great white
adopts a new strategy

435
00:29:38,310 --> 00:29:40,862
by launching a fast
vertical attack from below,

436
00:29:40,965 --> 00:29:42,931
out of the crew's
line of sight.

437
00:29:43,034 --> 00:29:45,620
It snatches the bait
with ease.

438
00:29:47,931 --> 00:29:49,068
[Tristan speaking]

439
00:29:57,000 --> 00:29:59,551
[narrator] This aggressive
male shark shows clearly,

440
00:29:59,655 --> 00:30:02,344
the intelligence and
the adaptability he'll need

441
00:30:02,448 --> 00:30:04,793
to hunt giant squid
in the deep.

442
00:30:07,310 --> 00:30:08,448
[Tristan speaking]

443
00:30:17,275 --> 00:30:18,379
[narrator]
To overcome a squid's

444
00:30:18,482 --> 00:30:21,034
sudden burst of speed
from jet propulsion,

445
00:30:21,137 --> 00:30:22,724
it makes sense
that the great whites

446
00:30:22,827 --> 00:30:25,793
would alter their strategy
to launch ambush attacks

447
00:30:25,896 --> 00:30:28,000
so they can catch the squid
off-guard.

448
00:30:32,620 --> 00:30:33,827
[Lily speaking]

449
00:30:36,448 --> 00:30:37,413
[Tristan speaking]

450
00:30:40,172 --> 00:30:42,448
[narrator] A massive
battle-hardened female

451
00:30:42,551 --> 00:30:43,758
appears in the area.

452
00:30:43,862 --> 00:30:45,413
[Lily speaking]

453
00:30:45,517 --> 00:30:48,068
[narrator] She's got the size
to take on a giant squid,

454
00:30:48,172 --> 00:30:49,448
but she's not alone.

455
00:30:51,206 --> 00:30:52,413
[Tristan speaking]

456
00:31:07,034 --> 00:31:08,206
[Lily speaking]

457
00:31:17,517 --> 00:31:18,724
[Tristan speaking]

458
00:31:45,724 --> 00:31:46,724
[Tristan] Whoo!

459
00:31:46,827 --> 00:31:48,482
That was an amazing dive.

460
00:31:48,586 --> 00:31:49,793
That was awesome.

461
00:31:49,896 --> 00:31:51,586
And that one
right in front of the cage,

462
00:31:51,689 --> 00:31:53,827
when it came
directly vertical...

463
00:31:57,965 --> 00:31:59,413
-I didn't even see it.
And you...
-Yeah.

464
00:31:59,517 --> 00:32:01,482
She was absolutely amazing.

465
00:32:03,172 --> 00:32:05,000
These sharks
are learning on the job.

466
00:32:05,103 --> 00:32:06,517
You know, they're learning
when the environment,

467
00:32:06,620 --> 00:32:08,310
the stimuli are changing,

468
00:32:08,413 --> 00:32:10,620
and responding to it
to try and get that food.

469
00:32:14,103 --> 00:32:15,655
[narrator]
Pursuing giant squid

470
00:32:15,758 --> 00:32:18,896
isn't like hunting seals
in daylight at the surface.

471
00:32:19,000 --> 00:32:22,000
They live in the darkness
of the twilight zone.

472
00:32:22,103 --> 00:32:26,206
A deadly expanse
where danger lurks everywhere.

473
00:32:26,310 --> 00:32:29,517
To navigate
this extreme environment,

474
00:32:29,620 --> 00:32:31,000
with their multiple limbs,

475
00:32:32,689 --> 00:32:35,827
bioluminescent organs
and huge eyes,

476
00:32:35,931 --> 00:32:39,206
they possess one of the most
complex neural networks

477
00:32:39,310 --> 00:32:40,724
in the animal kingdom.

478
00:32:42,448 --> 00:32:45,137
With all that, giant squid

479
00:32:45,241 --> 00:32:47,137
are a challenge
for white sharks.

480
00:32:55,965 --> 00:32:59,068
Now, the team prepares
for a night dive

481
00:32:59,172 --> 00:33:01,310
in the hopes of seeing
an interaction

482
00:33:01,413 --> 00:33:03,724
between squid
and white sharks.

483
00:33:05,931 --> 00:33:08,103
[Tristan] So far, this has
been a great expedition.

484
00:33:08,206 --> 00:33:11,034
All we need now,
is a monster squid.

485
00:33:13,206 --> 00:33:15,931
[narrator] Night is when squid
rise from the deep

486
00:33:16,034 --> 00:33:17,275
to the surface,

487
00:33:17,379 --> 00:33:19,068
and it's the most likely time

488
00:33:19,172 --> 00:33:22,206
that they might cross paths
with a white shark.

489
00:33:22,310 --> 00:33:24,068
[indistinct chatter]

490
00:33:24,172 --> 00:33:26,413
It's night time.
We're here at the drop-off.

491
00:33:26,517 --> 00:33:28,206
I've no idea
what's gonna come up,

492
00:33:28,310 --> 00:33:29,310
so we'll see what happens.

493
00:33:29,413 --> 00:33:31,413
All right, best of luck
for some squid.

494
00:33:31,517 --> 00:33:32,862
Kraken, here we come.

495
00:33:33,482 --> 00:33:34,482
[water splashes]

496
00:33:39,724 --> 00:33:41,448
Tristan! Tristan! Do you copy?

497
00:33:42,379 --> 00:33:43,551
[Tristan speaking over radio]

498
00:33:47,034 --> 00:33:50,137
All right, so Tristan is now
descending about 50 ft.

499
00:33:50,241 --> 00:33:52,758
Animals at this depth
cannot see red lights.

500
00:33:52,862 --> 00:33:54,896
So, he has a red light
on the cage,

501
00:33:55,000 --> 00:33:56,758
and our drop camera, as well.

502
00:33:56,862 --> 00:33:59,620
That makes him seem invisible
to the other animals.

503
00:33:59,724 --> 00:34:01,310
They will not be able
to see it

504
00:34:01,413 --> 00:34:05,034
and hopefully we'll be able
to see both of them at once

505
00:34:05,137 --> 00:34:06,620
and maybe even
a predation event.

506
00:34:07,448 --> 00:34:08,620
[Tristan speaking]

507
00:34:11,965 --> 00:34:13,172
[bubbling]

508
00:34:40,241 --> 00:34:41,793
[narrator] A green sea turtle.

509
00:34:41,896 --> 00:34:44,034
Their diet
is mostly sea grass,

510
00:34:44,137 --> 00:34:46,931
but they're known to feed
on bioluminescent species

511
00:34:47,034 --> 00:34:48,413
like jellyfish too.

512
00:34:50,413 --> 00:34:51,586
[Tristan speaking]

513
00:35:39,965 --> 00:35:40,896
[Lily] Oh, I see a squid.

514
00:35:41,000 --> 00:35:43,724
Coming in right now
to the live cam. Wow!

515
00:35:43,827 --> 00:35:46,344
Tristan, we just had
some squid swim by the lure.

516
00:35:46,965 --> 00:35:48,137
[Tristan speaking]

517
00:35:50,000 --> 00:35:53,655
[narrator] A Humboldt squid,
about five feet in length,

518
00:35:53,758 --> 00:35:55,827
appears near the LED lure.

519
00:35:55,931 --> 00:35:57,068
[Tristan speaking]

520
00:36:07,103 --> 00:36:09,000
[Lily] Oh, my God! Tristan,
I think I see a white shark

521
00:36:09,103 --> 00:36:10,689
right now on the live feed.

522
00:36:11,275 --> 00:36:12,551

[Tristan speaking]

531
00:37:12,517 --> 00:37:14,034
[narrator] Just moments
after spotting

532
00:37:14,137 --> 00:37:15,689
the huge Humboldt squid,

533
00:37:17,137 --> 00:37:20,275
a giant great white
surfaced from the deep

534
00:37:20,379 --> 00:37:22,275
and attacked their LED lure.

00:37:37,689 --> 00:37:40,448
on the night dive
is further proof

538
00:37:40,551 --> 00:37:42,793
that deadly clashes
between great whites

539
00:37:42,896 --> 00:37:44,862
and large squid species

540
00:37:44,965 --> 00:37:47,310
occur in the dark
around Guadalupe.

541
00:37:50,896 --> 00:37:51,896
[Tristan speaking]

542
00:37:55,689 --> 00:37:57,137
We're pulling you up
right now.

543
00:37:57,241 --> 00:37:58,206
[clanking]

544
00:38:01,000 --> 00:38:02,344
[Tristan] This has been
a great expedition.

545
00:38:02,448 --> 00:38:05,586
We had this big shark
pursuing the Humboldt squid.

546
00:38:05,689 --> 00:38:06,793
I'm guessing the scent,

547
00:38:06,896 --> 00:38:09,344
the visual stimuli,
all kind of together

548
00:38:09,448 --> 00:38:11,448
attracted that white shark
into it.

549
00:38:11,551 --> 00:38:13,689
Although this was
just one observation,

550
00:38:13,793 --> 00:38:15,655
we did see that
the white shark,

551
00:38:15,758 --> 00:38:17,827
like it does
with the other prey items,

552
00:38:17,931 --> 00:38:19,655
it was coming from underneath.

553
00:38:19,758 --> 00:38:21,448
You just imagine the battle

554
00:38:21,551 --> 00:38:23,379
between a big white shark
and a squid.

555
00:38:23,482 --> 00:38:24,827
What that would look like

556
00:38:24,931 --> 00:38:27,206
down at 500 meters
under the water.

557
00:38:28,275 --> 00:38:30,517
[narrator] Even though
it's nearly impossible

558
00:38:30,620 --> 00:38:33,517
to witness a great white
and giant squid

559
00:38:33,620 --> 00:38:35,103
battling in the depths,

560
00:38:35,206 --> 00:38:37,758
the researchers have handed
their observations over

561
00:38:37,862 --> 00:38:40,137
to a team of CGI artists,

562
00:38:40,241 --> 00:38:42,793
who are using the research
from the expedition

563
00:38:42,896 --> 00:38:45,586
to imagine what the battle
would look like.

564
00:38:46,965 --> 00:38:49,965
Under a full moon,
deep below the surface,

565
00:38:51,724 --> 00:38:55,758
a giant squid
emerges from the abyss.

566
00:38:57,310 --> 00:39:01,344
The real life kraken
searches for a midnight snack.

567
00:39:01,448 --> 00:39:04,827
But it's not the only
nocturnal predator
on the prowl.

568
00:39:07,344 --> 00:39:09,586
A large great white
has picked up

569
00:39:09,689 --> 00:39:12,689
the unmistakable scent
of his deadly foe.

570
00:39:15,275 --> 00:39:17,241
The squid spots
the great white

571
00:39:17,344 --> 00:39:18,931
with its enormous eye,

572
00:39:19,034 --> 00:39:22,068
and flashes a warning
for it to stay away.

573
00:39:22,172 --> 00:39:25,241
But the bio-electricity
from its light display

574
00:39:25,344 --> 00:39:27,931
triggers the shark's
ampullae of Lorenzini,

575
00:39:28,931 --> 00:39:31,206
and like
a heat-seeking missile,

576
00:39:31,310 --> 00:39:33,827
the great white
locks onto its target.

577
00:39:38,517 --> 00:39:39,655
[whooshes]

578
00:39:39,758 --> 00:39:43,068
[narrator] The giant squid
uses its jet propulsion

579
00:39:43,172 --> 00:39:45,758
to narrowly escape
the shark's first strike.

580
00:39:48,724 --> 00:39:51,344
-[whooshes]
-The shark charges back in,

581
00:39:51,448 --> 00:39:54,137
and the squid's jet
has run out of fuel.

582
00:39:55,551 --> 00:39:59,448
And the two giants
engage in a deadly embrace.

583
00:40:00,586 --> 00:40:01,413
[cracking]

584
00:40:06,793 --> 00:40:08,517
[crunching]

585
00:40:18,689 --> 00:40:19,689
[chomps]

586
00:40:24,517 --> 00:40:26,241
[narrator] The injured
fighters disengage.

587
00:40:26,344 --> 00:40:27,896
[water warbling]

588
00:40:28,000 --> 00:40:30,413
[narrator]
But the shark's tasted blood,

589
00:40:30,517 --> 00:40:33,448
and isn't about to give up
on this potential feast.

590
00:40:50,862 --> 00:40:52,413
[chomping]

591
00:40:54,482 --> 00:40:57,586
[narrator] This clash
of the titans is over.

592
00:40:57,689 --> 00:41:01,241
And the white shark digs
into its hard-earned meal

593
00:41:01,344 --> 00:41:02,379
in the deep.

594
00:41:04,689 --> 00:41:05,827
[Tristan] If I was announcing

595
00:41:05,931 --> 00:41:07,793
a fight between
the giant squid,

596
00:41:07,896 --> 00:41:09,068
the white shark,

597
00:41:09,172 --> 00:41:11,793
really, you've got
the white shark in one corner,

598
00:41:11,896 --> 00:41:13,758
power, speed, precision,

599
00:41:13,862 --> 00:41:15,931
slicing triangular teeth.

600
00:41:18,586 --> 00:41:21,482
And, in the other corner
we've got guile, mimicry,

601
00:41:22,241 --> 00:41:23,689
suction cups with razor teeth,

602
00:41:25,000 --> 00:41:26,344
that massive beak,

603
00:41:27,689 --> 00:41:29,344
and huge arms
to engulf something.

604
00:41:30,724 --> 00:41:31,827
Well, I think these are both

605
00:41:31,931 --> 00:41:34,379
the most formidable predators
on the planet.
