All language subtitles for Shark Week 2020 Monster Under the Bridge [13-08-2020] [MKV]_track3_eng

♪♪

Dr. Guttridge:
According to folklore here,
there's a legendary hammerhead

That stalks
the seven mile bridge,

And it's an absolute monster.

Man #1:
I've seen him countless times.

Man #2: That thing's hammer
is six, eight feet wide.

Man #1: He's just so much bigger
than any of the other sharks.

Narrator: Deep in the heart
of the florida keys,

In the shadows of the iconic
seven mile bridge...

♪♪

Lives a monster.

They call him big moe.

These stories date back
30-plus years.

So if this legend is true,

We could be dealing
with a huge hammerhead

That is 50 years of age.

Narrator:
Scientists believe big moe

Could be the largest hammerhead
on the planet

And that he's a member of an
entirely new species of shark.

It might sound
a bit far-fetched,

But in fact,
we have some data that suggests

That this
might actually be true.

And we're gonna discover
something really unique

About a cryptic, secretive
new species of hammerhead.

We want to get to the truth

Behind this huge,
great hammerhead.

Narrator: To unravel
the mystery of big moe...

Man: Hammer, hammer!

Narrator: ...Two teams
of researchers embark

On an expedition
around the florida keys.

Man:
I just saw something massive.

Narrator: This mission
could lead to the discovery

Of a new mega hammerhead
species.

Oh!
Get this out of my way!

Narrator:
In 1912, a bridge was built
connecting mainland florida

To the then undeveloped wilds
of the florida keys.

It's called
the seven mile bridge.

And just as
this overseas highway

Dramatically changed
the economy of florida,

Its physical structure
also transformed

The underwater world
beneath the bridge.

Today, this artificial
reef superhighway

Is home to monster sharks.

Dr. Guttridge:
Every single one of these pylons
is growing life on it,

Is like a mini ecosystem
in itself.

It's provided
additional habitats

For loads of different species,

Because there's quite a bit
of shadowing

That's caused
by the big structures.

This is an opportunity
for the biggest predators

To rest
in those shadow areas

And essentially
launch attacks from there.

♪♪

Mcdonnell: You've got miles
of these bridges.

They act as an artificial reef,
so things can grow on them.

Fish are attracted to it, and
these bridges as these barriers

Between the gulf of mexico
and the atlantic ocean,

So you have these two rich
ecosystems that merge here.

Dr. Hammerschlag:
I think that big moe
is using this bridge

To ambush something
like a tarpon

That is moving between
the gulf of mexico

And the atlantic ocean.

Narrator:
Beyond his use of the bridges,

Big moe is also defined
by his massive size.

Great hammerheads rarely grow
to be longer than 12 feet

Or weigh more
than a thousand pounds,

But numerous reports of big moe

Estimate his length
at around 20 feet

And his weight at nearly a ton.

And recently, the dna of two
massive male great hammerheads

Caught near seven mile bridge

Revealed something incredible
about their genetics.

Their common stock dna structure

Didn't match any other
hammerheads in the region.

This sparked the theory
that specimens like big moe

And these outliers might belong
to a new species of shark

Known as the keys hammerhead.

Could there be the keys
great hammerhead?

That's what we want to find out.

Narrator:
If the keys hammerhead is real,

It could be
the ultimate predator.

Like other hammerheads,

They would possess
nearly 360-degree vision

So they could see
in almost any direction.

But that's not all.

Their extra wide cephalofoils

Would spread
their ampullae of lorenzini

Over a greater surface area.

These special sensory organs
allow them to zero in

On weak electrical signals
generated by prey.

♪♪

To find out if they exist,

The teams will collect
dna samples

From great hammerheads
in the region

And have them analyzed by
shark geneticist david portnoy.

Hey, dave,
how are you doing?

Good.
How are you guys?

We're ready for action.

David portnoy is a leading
geneticist in the u.S.

When it comes to sharks,
he's the man you go to.

So, guys, the idea is that
these really big hammerheads

Could be this
unique evolutionary lineage.

We need tissue
from the real big ones.

You know, maybe there's
something to this ecosystem

That is attracting them
and keeps them coming back here.

Good luck.

Alright, man.
Thanks so much.

Talk soon.

♪♪

Alright, here we go,
the game plan.

This map really allows you
to kind of visualize

The scale of these bridges.

You know, they're connecting
all these different keys.

There's so many places
for these hammerheads to use.

Quite a lot
to work with here.

I would suggest that we probably
split up --

You know, divide and conquer

To cover as much ground
as we can

To try to find
these big hammers.

I cannot wait to get
in the water

And see if I can find big moe.

No competition at all.

Definitely not a competition,
neil, okay?

Yeah.
I mean, this is a team effort.

Nobody's keeping score, but
we're definitely keeping score.

♪♪

My plan is to start
at bahia honda bridge.

This is where
big moe was last seen,

And this is the hot spot.

♪♪

If a great hammerhead comes in,
I'm gonna sneak in,

Deploy my biopsy, take a sample,
and leave it with a tag.

♪♪

These bridges
are a unique habitat.

There's strong current.

With the biggest hammerhead
in shark week history.

Narrator:
In key west, florida,

A massive hammerhead
called big moe

Stalks the waters
under seven mile bridge.

Two teams of researchers
believe this beast

Could be
a brand-new hammerhead species

That's larger than any other
on the planet.

[ thunder crashes ]

To test their theory,

Marine biologist
tristan guttridge

Dives a big moe hot spot
to obtain a genetic sample.

And he's about to get
his first shot

At a groundbreaking discovery.

Narrator:
After an hour in the water,

The team heads back
to the surface.

And while they didn't succeed
in getting a genetic sample,

The appearance of a great
hammerhead under the bridge

Is a promising start
to the mission.

Dr. Guttridge:
Just got back off an epic dive,

And I actually saw
a huge hammerhead...

I can hear your heart thumping
through the walkie-talkie here.

I took a shot, but the shark
was kind of turning

As I tried
to get a genetic sample,

And it just bounced
straight off.

But there's definitely
big sharks that use that bridge.

♪♪

Narrator: On the other side
of big moe territory,

Neil adopts a different strategy
to find the legendary shark.

Let's get the bait in the water.
Let's do it.

Narrator:
He and laura are deploying
baited buoys from the surface

To attract great hammerheads.

If one takes the bait,

They'll move in for a genetic
sample alongside the boat.

I'll work the tag
if you're gonna do the biopsy.

Yep. Hopefully we can see
who's related to who

And what the interconnectedness
is of the populations.

The genetic work will actually
allow us to determine

Is there a big moe,

Is there something unique

About the keys
great hammerhead,

And try to get an understanding

About the population
of great hammerheads

That are using
the seven mile bridge.

Narrator:
In addition to the buoys,

The team also deploys a bruv,

Or baited remote
underwater video,

So they can spy
on big moe's territory

When they're not around.

Alright, laura,
turn on the camera.

1, 2, 3.

♪♪

Narrator: Shortly after dropping
their bruv,

One of neil's baited buoys
goes on the run.

Dr. Hammerschlag:
Bucco put us on top.

Let's see if we can get a look.

We've got a shark
on this buoy.

Fingers crossed it's big moe.

♪♪

-Wow.
-Holy moly.
-Gosh.

That's a tarpon-eating
bull shark.

Narrator: The baited buoys
capture a bull shark.

Not the target species
they are looking for,

But an impressive specimen
nonetheless.

Dr. Hammerschlag: Get the bolt
cutters, send him on his way.

Narrator: This powerfully built
and stocky species.

Are pound for pound some of the
strongest sharks on the planet.

♪♪

Dr. Hammerschlag: Careful!

Narrator:
When caught on the line,

This makes them
notoriously aggressive.

You know, about that night dive
we're gonna do under the bridge,

I really hope we don't bump into
one of those bull sharks.

Yeah.

With the light
beginning to fade,

They retrieve their bruv.

Oh, yeah.
Alright. Awesome.

Okay.

Let's check it out.

Alright.
Let's see what we got here.

Alright.

I got an octopus.

Octopi like this
have highly evolved brains

So they can operate their
eight tentacles independently.

This makes them

Some of the most intelligent
animals in the ocean.

Oh!
Look at the octopus go.

Zipped out of there.
He took off.

Whoa-ho-ho!

That's crazy.
A huge hammerhead.

That is awesome!

Came and, like,
sucked it right up.

The bruv captures a massive
great hammerhead

That could be over 12 feet long.

That is so crazy.

While this great hammerhead

Isn't as large as the one
reported in big moe sightings,

It's further proof

That the bridge is a hot spot
for these monster sharks.

Back at bahia honda bridge,

Tristan and his team
deploy a new strategy --

Shadowing local fishermen.

-Alright!
-Yeah!

Dr. Guttridge:
Local fishermen come here

To target
the huge spawning tarpon run.

And if one of them hooks up
on a tarpon

And they happen to see
a big hammerhead,

We're hoping that we'll be able
to come in and tag that shark.

Of a legendary shark
named big moe.

With a possible size
of more than 20 feet long

And weighing nearly a ton,
big moe is an outlier.

And this means
he could be part

Of a new subspecies
of hammerhead.

To find out, researchers
have to obtain dna samples

From great hammerheads
in the region.

On the second great hammerhead,
which will allow them

To track its movements
around the bridges.

That was incredible.

I just had a 14-foot
great hammerhead

Up on the back of the boat.

I'm two for two

That means preparing for a night
dive around seven mile bridge.

Dr. Hammerschlag: I would love
to see a hammerhead.

-Hey, dave.
-Hey, dave. How are you doing?

Hey, guys,
good to see you again.

A lot happened in the field.

I saw the biggest hammerhead
I've ever seen in my life.

Dr. Hammerschlag: Yeah, and we
saw the smallest hammerhead

We've ever seen in our life.

Dr. Guttridge:
We did exactly what you asked.

What have you got for us?

Okay, so we've been able
to take the samples

That you provided
from the field,

And you guys are not going
to believe the results.

They're really interesting.

Of the specimens analyzed,

We discovered that some of them
are actually related.

That is unbelievable.

That's so crazy.

Dr. Portnoy:
And most of those relatives

Were adult siblings
captured in the same area.

But sometimes we capture them
years apart from one another.

That is crazy.

What's so amazing
about this is hammerheads

Can travel thousands of miles,

So they can essentially
go wherever they want.

But for some reason, they appear
to be favoring habitat

Around south florida.

Dr. Hammerschlag:
Yeah, this is amazing.

The fact that we can
identify siblings

In such a small dataset
opens up so much more.

Dr. Portnoy:
Well, I think it indicates

That they're
displaying site fidelity.

Narrator: Site fidelity means
these sharks frequently return

To a specific area for important
parts of their life cycle,

Like mating, pupping,
and to feed.

Dr. Portnoy: It's possible that
big moe is, in fact,

One shark that's reappearing
at the bridge every year

Because it's such
a productive habitat.

Narrator: The numerous
eyewitness reports of big moe,

Combined with the evidence that
many hammerheads in the region

Are related,
leads to a new possible theory.

Big moe might be just one member
of a huge family of sharks

That call the bridges
of the florida keys home.

And while there could be a new
species of hammerhead

Somewhere out there,
more data is needed.

Hammerhead!
It's a massive hammerhead!

Dr. Guttridge: Because it's such
a highly migratory species,

There's a tendency for all of us
to think that these animals

Just travel
all over the place randomly.

But we're beginning to learn
that they show repeatability

In where they go.

And we think there might be
a genetic structure

That's underpinning
this behavior.

Mcdonnell: I'm saying it now.

I think big moe
is actually big moena.

I think that that might just be
a really massive female

That is stalking these bridges.

So girl power.

Dr. Hammerschlag: The great
hammerhead shark is an animal

That we know so little about.

Yet it's so important
because they are a species

That is globally endangered.

Narrator: While there's still
a lot to learn about large

Great hammerheads like big moe,

The teams' efforts have
brought them one step closer

To solving the mysteries behind
some of the greatest sharks

In the ocean.
