[Tristan Guttridge] It's a hammer. It's a hammer. Woo!
[Tristan] In Andros, there are some huge great hammerheads.
Official YIFY movies site: YTS.MX
[Andy Casagrande] They can become over a thousand pounds.
They can literally reach 20 feet long.
What do these great hammerheads need to eat
that will sustain that size?
[Tristan] Most people really consider the hammerhead
as kind of like a stingray specialist.
But now new evidence suggests...
great hammerheads in Andros
actually specialize hunting other sharks.
[man] Working on another shark.
[man] Holy [bleep].
[Andy] Just recently right here in Andros,
some of the most incredible footage
was captured of a massive great hammerhead
hunting a shark right underneath
-a fisherman's boat. -[man] Oh, God.
[Khrys Carroll] What's so unique about Andros Island
is the hammerheads have little to no interaction with humans.
[Tristan speaking]
[Andy] Andros is the Wild, Wild West.
-[Tristan speaking] -Whoa! Whoa!
[Annie Guttridge] We wanna know, are these great hammerheads
here in Andros hunting smaller sharks?
[Tristan] It's a hammer. It's a hammer.
-[man] You gotta be careful. -[Annie] Careful, careful, careful, careful.
My name is Dr. Tristan Guttridge. I'm a behavioral ecologist.
I've been working with great hammerhead sharks
for over a decade.
To me, the great hammerhead is one of the most iconic,
charismatic shark species that lives on the planet.
They reach huge sizes. I'm talking almost 20 feet.
Plus, they have a head that is shaped like a hammer.
And they use that hammer to pin prey down.
Hammerheads are perfectly evolved
for hunting stingrays.
[Tristan] But now new evidence
here in Andros suggests
these hammerheads are reaching huge sizes
by specializing on hunting other sharks.
[man] That is crazy. Look at this hammerhead.
Oh, it's trying to eat a shark. Oh, my God.
Holy [bleep].
[Annie] We had a local fisher here showing
a great hammerhead hunting on another shark.
[man] He's working on another shark.
[man] Holy [bleep].
The lemon shark was probably like six feet.
The hammerhead was twice its size.
[man] Oh, God.
[Skye Minnis] And it was just chasing it,
trying to get a snack.
[narrator] Researchers need to determine if these videos
are of isolated events
or if they're a sign of a shocking change
to the diet of great hammerheads of Andros Island.
[Tristan] Andros is just a few hundred miles from the US.
It's the biggest island in The Bahamas.
It's critical for us to understand the role
that these bigger predators play in this system
to keep it healthy.
[narrator] But the only way to figure out
what these hammerheads are eating
is to send live tissue samples to an outside lab.
[Tristan] We're gonna take muscle samples
from the great hammerheads themselves.
We can take that sample and we can analyze
its chemical composition.
We can learn about what this hammerhead
has been eating across the last year of its life.
[narrator] To get the sample, they have to get
within inches of the hammerhead.
To get this job done safely
for both the humans and the sharks,
Tristan has assembled an all-star team.
[Tristan] All right. Load up.
[narrator] Including local shark experts,
Khrys Carroll...
I'm a marine scientist with Saving the Blue.
[narrator] and Skye Minnis.
[Skye] I grew up in the ocean
fishing in the shallows with my grandmother.
Now, I am a student at BAMSI.
[narrator] Another Andros local joining
the team is Rontaa Bain,
an experienced freediver with the skills required
to take biopsy samples from free swimming great hammerhead sharks.
[Rontaa] The biggest hammerhead I ever seen
was four meters. I thought it was a boat.
[narrator] Watching their backs
is experienced underwater cameraman,
Andy Casagrande.
For the past 20 years, I've traveled
all over the planet
filming nearly every species of shark.
The great hammerhead is one of my favorites.
[narrator] And Tristan's wife, Annie,
a fearless freediver
who has worked with hammerheads
for over a decade.
Together, they've devised a radical new plan
to lure in giant hammerheads for biopsies.
[Tristan] Taking muscle samples from the great
hammerheads themselves is extremely challenging.
So we've designed
three state-of-the-art decoys.
We've got Octobot
that's gonna mimic
a large octopus or a big squid.
We've got Roboshark here
that's gonna mimic a blacknose,
a small coastal species,
to hopefully see what hammerheads do with sharks.
And, of course, the return of our good friend,
Roboray, mimics a southern stingray.
These look super realistic.
[Andy] Roboray. Roboray.
Last year we had a great hammerhead
come hard in on Roboray.
And I'm excited to try her again.
[narrator] Roboray is best suited for attracting hammerheads
in shallow sandy bottom environments.
But the team has plans to explore
all of Andros' unique underwater habitats,
and that's where Roboshark and Octobot come into play.
[Tristan] We've designed Octobot to draw in
a hammerhead where cephalopods,
squid are coming up during the night to feed.
Roboshark, it's the perfect size
for cruising reef habitat.
The decoy delta force.
I mean, I think any big shark, they're gonna come in and check it out.
These decoys will create a distraction
and then you can come in--
And get the biopsy.
-[Tristan] Exactly. -[Andy] Yes.
Some people might think it's very unorthodox,
but in my opinion, unless you think outside the box,
swim outside the cage, you're never gonna learn
anything new about these animals.
Plan is to set up on three different locations
in real diverse habitats.
Predator Channel in this area here.
[Khrys] Predator Channel, we've known to see
massive great hammerheads.
[Tristan] The dropoff is a perfect launching site
for Octobot.
And then we have Stingray Shelf where we've seen
lots of stingrays before, other small sharks as well.
I just have one question.
What's up with your Mohawk, ABC?
It's not a Mohawk.
It's a shark-hawk.
-Sorry, buddy. -[laughter]
-[Tristan] Everyone ready? -[Skye] Let's do it.
[Tristan] Today, we're starting at Predator Channel.
Old faithful.
It's the site that I've seen the most great hammerheads
here in Andros and a great location
to deploy Roboshark
because it's this transition zone
from the dropoff to the flats.
That's where these hammerheads are working
'cause they can launch attacks.
[narrator] Besides being a known hammerhead hotspot,
Predator Channel is also the location
in which local fishermen recently filmed
the great hammerhead hunting a smaller shark.
[Annie] So we're here in Predator Channel.
We're setting up our BRUV to deploy Roboshark.
So we have some freshly caught yellowtail.
They're very abundant in The Bahamas.
We don't typically filet them
but when we're working with blunt knives,
we make it work.
Annie's gonna be preparing bait for the BRUV,
a baited remote underwater video camera
that has a live feed.
And I'm gonna be scanning the water
for a great hammerhead.
[dramatic music playing]
[Khrys] What are you doing? That is disgusting.
This is the glamorous part of shark week.
No. Oh.
-[Andy] Oh, God. -No.
I've just been sick a little bit in my mouth.
-You want another bit? -[Khrys] I would love another piece.
-Please don't. -Fresh mackerel is probably pretty good.
Mmm.
-[laughs] -Primo.
[Andy] Wow.
No.
[dramatic music playing]
[Tristan] Hammer! Hammer!
[Skye] Hammerhead! Hammer, hammer, hammer!
People!
[Annie] Where's Andy? Andy?
[indistinct chatter]
It's a big female.
Get Roboshark ready.
She's headed towards the wreck.
[narrator] Tristan has spotted
the ideal candidate for a tissue sample.
A great hammerhead that's around 12 feet long.
Large enough to be a shark killer.
[Tristan speaking]
[Khrys speaking]
[Tristan speaking]
[Andy speaking]
[Tristan speaking]
Just interesting.
How is everything down there? Anything yet?
[Andy speaking]
[Tristan speaking]
[Andy speaking]
[Tristan speaking]
Tristan, ABC, the live feed is in position.
Say cheese, guys.
[Tristan speaking]
[Andy speaking]
[Tristan speaking]
[narrator] Even though this female tiger shark
is just a juvenile,
it could one day grow
to be up to 16 feet long
and weigh more than 2,000 pounds.
[Tristan speaking]
I think I see a fin off the back of the boat.
No, no, no. There. There. It's a hammer.
Oh. That's a hammerhead. That's a hammerhead.
Big. Yes.
[Rontaa] A hundred percent real.
-Guys, that is [bleep] huge. -Where is it?
-Holy [bleep]. -[Skye laughs]
[Khrys speaking]
[Tristan speaking]
[Khrys speaking]
[Tristan speaking]
[dramatic music playing]
[Tristan speaking]
[Khrys speaking]
[Tristan speaking]
-[Annie] Rontaa, biopsy. -[narrator] With this 12-foot
hammerhead distracted by Roboshark,
the team's freediver
and biopsy specialist, Rontaa,
jumps in the water
so he can get in position
for a tissue sample.
[Tristan speaking]
-Whoa. -Oh, my God.
[Tristan speaking]
[narrator] By triggering a predatory attack from the hammerhead,
Roboshark has done its job a little too well.
And with the shark leaving the area,
the team calls the dive.
[Tristan speaking]
[Andy speaking]
[Rontaa speaking]
You guys head back in.
[Tristan speaking]
Wow. That was a beautiful hammerhead.
-How big was it? -[Andy] Maybe 12 feet.
Super confident shark.
[narrator] Even though Roboshark malfunctioned
before the team had a chance to biopsy the hammerhead,
they still made important observations.
[Andy] Tristan, that was pretty incredible, man.
Roboshark didn't stand a chance.
-[makes sound] -[laughs]
[Andy] Yeah. That's pretty much what happened.
With our decoy, we were able to elicit
predatory behaviors of hammerheads that might
be cruising that reef habitat.
This is fantastic evidence that showcases
the predatory prowess of these giant
great hammerheads.
But now we want to switch
things up and bring out Octobot.
We know that hammerheads feed out in the deep water,
hitting squid and other cephalopods.
So what I'm hoping to do is see
what big hammerhead we can intercept
that's cruising that zone.
[narrator] Octobot was designed specifically
for attracting hammerheads at night near dropoffs.
This is where the shallows suddenly descent
into thousands of feet of open water.
As we know, octopus, squid,
they come up at night to feed,
and we have Octobot here.
Tonight will be a dusk dive on the dropoff.
We're gonna swim Octobot right over the dropoff
that goes down to almost 10,000 feet.
And this is where cephalopods,
squid are coming up during the night to feed.
So I'm taking the lights for bioluminescence, right?
Right. So we've got the visual cue
of the actual octopus and we've also got
the lights too to mimic that.
-That's pretty awesome. -[Tristan] We take this
decoy down off the dropoff.
Maybe we'll get a hit from one of these
big hammerheads that feeds out in the pelagic zone,
which is very different to some of the hammers that feed
on stingrays and sharks on the flats.
[narrator] The pelagic zone is the open ocean
far from shore.
And researchers believe great hammerheads hunt
at night here, where they can encounter lethal deep sea
predators like swordfish
and even the giant squid.
In this dangerous environment,
darkness can provide cover from prey that can bite back.
So what do you think?
Yeah, let's get kraken.
Oh, my God.
[Andy] Every time I go down
in the dark underwater,
it's a little unnerving
because you can't see much further than your face.
These rebreathers, they're great but it's hard work.
-Yeah. -[Tristan] So check everything before you go in.
[narrator] Besides monitoring their complex
rebreather equipment, Tristan will also go
for the all-important hammerhead tissue sample,
-if one appears. -[Andy] All right.
-Feeling good, Tristan? -Oh, yeah. I'm ready.
[Andy] All right. Let's do this.
Looks good. We'll see you in an hour or two.
[Annie] Five, four, three, two, one.
[Tristan speaking]
[Andy speaking]
[Tristan speaking]
[Andy speaking]
[narrator] Blacknose sharks can be found
all over the southeast Atlantic.
The largest this species gets is around six feet long,
making them ideal prey for a shark-killing hammerhead.
[Tristan speaking]
[Andy speaking]
[Tristan speaking]
[Andy speaking]
[Tristan speaking]
[Andy speaking]
[Tristan speaking]
[Andy speaking]
[Tristan speaking]
[Andy speaking]
[Tristan speaking]
[narrator] Before attacking,
great hammerheads scan their surroundings
with their massive hammer-shaped cephalofoils.
These are covered in electroreceptors
called ampullae of Lorenzini,
which allow them to detect electrical currents
like heartbeats
or the small electric motors
in Octobot.
[Tristan] Oh!
[Andy speaking]
[Tristan speaking]
[Andy speaking]
[Tristan speaking]
[Andy speaking]
[narrator] In the dark,
off Andros Island in The Bahamas,
Tristan Guttridge and Andy Casagrande
are using a squid decoy called Octobot
to lure in monster hammerheads.
[Tristan speaking]
[Andy speaking]
[Tristan speaking]
We lost Octobot.
Something just pulled it over the edge.
[Annie] Yeah. We saw something big.
The current is quite strong.
Wow. I mean, we were in great position.
We were right on the edge of the drop off,
and then it yanked straight off my hand.
Dude.
Octobot live on in memory.
Octobot.
[chuckles]
[Tristan] Last night was crazy.
We had a huge great hammerhead.
And as I was on the edge of the drop off,
I was holding the controller
and it got pulled out of my hands.
[Andy] By the time we got to the drop off,
Octobot was gone
and it was impossible to retrieve.
We're just not equipped to go
that deep to recover.
-That actually was a shark. -That was... That was a shark.
-That is a shark. -That is... That was something.
[narrator] Analysis from Octobot's camera
at the moment the controller was ripped
from Tristan's hands,
shows something coming into frame.
But whether or not it was a great hammerhead is unclear.
If it is, the decoys might be working too well
in eliciting predatory behavior.
With Octobot gone
and Roboshark in the shop for repairs,
the team turns to their last decoy.
[Andy] Now it's time to break out
our old pal, Roboray.
And we're gonna head to this awesome spot
called Gibson Cay.
It's a very productive area.
There's sharks here. There's stingrays.
There's lots of game fish.
This place is a known area...
where hammerheads come to hunt other sharks.
This is where Annie and I saw the hammerhead predating
on a shark in the shallows.
[Annie] Oh, my God!
She's hunting. She's on the reef shark.
It's definitely hunting. Oh, my God!
My God. Look at it there.
[Rontaa] It's eating another shark.
So we split up into two teams.
I'm here with Khrys and Skye.
Can you hand me that BRUV?
[Andy] And we got Tristan and Annie.
Right now, they're fishing over there.
They're hoping to catch a big hammerhead
and pull a biopsy,
because we wanna know
what these monster hammerheads are eating.
This is number one, so 1A.
It's why I like working with my wife
'cause she's way more organized than me.
[narrator] With two decoys down
and no tissue samples yet,
Tristan and Annie turn to drumline fishing,
a tried and true method for hooking up hammerheads
to get the biopsies they need.
[Tristan] I haven't entirely abandoned the decoys
but we have now moved to a more traditional method
which is catch and release,
where we can take a biological tissue sample,
muscle from the side of a vessel
in a more controlled manner.
So we're deploying some drumlines.
We have a weight
which is connected to this long yellow line,
which is then connected to some buoys
and then some mono.
[Tristan] The advantage of using the drumlines
is that we can actually have the animal
next to the side of the vessel
and be able to get much more detailed information
by being able to capture them.
There is a downside.
It's quite a high pressure situation.
You're dealing with a huge animal that has big teeth,
that can slap you in the face with its big tail.
So you really need to be quick and efficient
and make sure that you're being safe
when you're working with these big sharks.
-[Annie] Tristan, you ready? -Yeah.
A little bit further.
[Annie chuckles] Not ready.
[Tristan] Okay. It's good here.
We're actually gonna be set anchored
just around 500 feet away from these rigs
so we can see if anything gets caught
and then we can go straight to it,
work it up, measure it, take our muscle sample,
and then the shark will hopefully be swimming
from bite to release within 12 or 15 minutes.
-Nice. -Very nice.
We're now set up. You can see the rigs.
We've got one, two, three, four, five
-across the channel. -[Annie] When a hammer hits,
we certainly will know about it.
[narrator] With their drumlines set,
Annie and Tristan wait for a hit,
while Andy, Khrys, and Skye prepare to jump in
with Roboray.
I think this is the perfect place.
[Andy] All right. Roboray, game time.
[Skye] We're gonna use the return of Roboray
to get the hammerheads in really close
to collect a tissue sample.
Me and Khrys, we're gonna have front row seat
and we're gonna see what comes in.
I'll keep my eyes open for any hammers
or any other tigers that might be in the area.
What could go wrong?
-[Skye] Let's do this. -[Khrys] Okay. Cool.
[narrator] The team has also deployed
over a dozen BRUVs,
which are baited cameras
rigged with up to 25 pounds of tuna.
Between the BRUVs and Roboray,
any great hammerheads in the area
are in for a feast.
[Skye speaking]
[Khrys speaking]
[Skye speaking]
[Khrys speaking]
[narrator] Nurse sharks are bottom feeders.
They eat almost anything they find on the ocean floor,
crushing coral, crustaceans, and small bony fish
with their many rows of small serrated teeth.
[Skye speaking]
[Khrys speaking]
[Skye speaking]
[narrator] Another species takes interest
in the team's bait.
Reef sharks like this are a cornerstone
of the habitats around Andros.
[Skye speaking]
[narrator] Reef sharks might have learned
to find safety in numbers,
because when they're young,
they're hunted by great hammerheads.
[Skye speaking]
[Khrys speaking]
[Skye] Whoa!
[Khrys speaking]
[Skye speaking]
[Khrys speaking]
[Skye speaking]
[Khrys speaking]
[Skye speaking]
[Andy] I copy you.
Roboray is away.
Repeat, Roboray is in the water.
[suspenseful music playing]
[Andy] We're sending in Rontaa.
[narrator] With Roboray deployed,
Rontaa hits the water,
floating at the surface while he waits
for the perfect opportunity
to go in for a tissue sample.
[Andy] Rontaa now is hovering above you guys.
[Khrys speaking]
[Skye speaking]
[Khrys speaking]
[Skye speaking]
[Khrys speaking]
[Skye] Whoa!
[Khrys speaking]
[Skye speaking]
[Khrys speaking]
[Andy speaking]
[Khrys speaking]
[Skye speaking]
[Khrys speaking]
[Andy] I copy you, Khrys.
[narrator] Just like with Roboshark and Octobot,
Roboray succeeds in eliciting
a strong predatory response
from a great hammerhead.
But the shark takes off before the team has a chance
to obtain a biopsy.
-Yeah. -Whoo!
What about that dive, guys.
-That was awesome. -It was amazing.
The surge was kind of gnarly
but the sharks definitely came in full effect.
That moment when we saw the hammerhead swim above us--
Yeah. That was... something else.
It was like a buffet for the hammerhead.
You had reefies,
you had the little nurse, and Roboray.
[Andy] Nice work.
[makes explosive sound]
One, two, three.
So we just put another one there.
Four and five.
No bait. Rebait.
-[Annie] What bait is it? -[Tristan] Cuda.
So we've had some ups and downs with the decoys.
These are smart sharks.
But we do have a backup
and that is we try and catch one of these animals
and take a biopsy on the side of the boat.
There's a higher chance of getting hooked by a hook
than getting bit by a shark, definitely.
-Ready to go in? -[Rontaa] Yup.
Bait in.
Like a well-oiled machine,
research machine.
Shark one! Shark one!
-Shark one! -Oh, okay. Yes!
Oh, wow. That's moving.
Stephano, move round and go up the channel
and then we'll pull it in from there.
[narrator] The team's patience finally pays off...
as Tristan and Annie get a hit
on one of their drum lines.
[Tristan] Slow down. Slow down.
It's here on the left.
It is a big shark
'cause it's towing that line.
[Annie] Definitely a big shark, a hundred percent.
[Tristan] Can't see what it is.
-Go over. -[Skye] We're right...
We're right on top of it.
Just be careful it doesn't get in your legs, Julian.
-[Julian] It's a hammer! -[Tristan] It's a hammer!
-It's a hammer! -[Julian] Oh, my God!
-[Tristan] Woo! -[Julian] Woo!
It's a hammerhead.
We've caught a hammerhead
in the channel.
That is not small either.
It's not small.
[narrator] This hammerhead is 12 feet long,
big enough to hunt other sharks.
But the only way to see if this one is a shark killer
is to get the tissue sample.
[Annie] Definitely female I say, yeah?
-Yeah. Yeah. -[Julian] Go, go, go, go, go,
go, go, go, go, go.
[Tristan] Can't get the tail.
[grunts] We radioed them to let them know.
[Stephano speaking]
[Andy] Is it a hambone or they don't know?
-[man] Is it hammer? -[Stephano speaking]
-It's a hammer. It's a hammer. -What?
-All right. Let's go. Let's go. -[Andy] Put the drone up.
[Skye] Oh, look at that.
They got it.
[Khrys] That is awesome.
What a beauty.
Tristan and Annie just caught a hammerhead.
They're gonna get a biopsy.
I'm gonna jump in the water
to film the release.
[Annie] All right. Here we go. This is it, people.
This is it. Nice and easy.
This is it.
Here she comes.
[Tristan] Yeah, I've got it.
Grab its head.
Okay. Pass the biopsy.
[Annie] Look out. Look out.
-Tristan, stand by. -Yeah. I know.
I'm ready.
[Annie] All right. She's set.
[Tristan] Let it go. Let it go.
[Annie] Careful, careful, careful. Careful!
[Tristan] Grab its head.
[Annie] Careful, careful, careful.
-Careful! -[Tristan] Let it go.
[Annie] Tristan, what now?
[Tristan] Okay. Pass the biopsy.
All right. That's good enough.
All right. We're gonna have to release it.
[Annie] She's set.
-She's about ready to go. -[Tristan] That's it.
-Keep trying to get the hook out. -[Annie] Look out.
-Tristan, stand by. -Yeah. I know.
I'm ready.
-She's good? She free? -She's free.
[Tristan] Let her go. Let her go.
She swims.
[dramatic music playing]
[cheering]
Ow!
Sorry.
[Tristan] We got the muscle sample.
We can essentially track
what that hammerhead has been eating
the last year.
You are essentially what you eat.
[narrator] At just under 12 feet long,
the great hammerhead they sampled is well on its way
to becoming one of the behemoths Andros is known for.
And at that size, it's more than big enough
to be a shark killer.
[Tristan] And that's the muscle sample.
Just putting it in here for now.
And this is gold dust.
We now need more samples from great hammerheads here
to really try and understand
if they're specializing on hunting other sharks.
[narrator] But Tristan needs more
than just hammerhead samples.
For this comparative analysis to work,
the team will also need tissue
of potential hammerhead prey species
in the area,
including other sharks.
Shark on! Shark on!
[Tristan] The next big challenge is to go out
and sample the prey species
that these hammerheads are focusing on.
Look at this five-foot reef shark.
Perfect prey, I think, for a 12-foot hammerhead.
We need blacktip sharks,
blacknose, Caribbean reef sharks,
we need southern stingrays.
We caught a lemon shark now.
That would be a perfect snack for a hammerhead.
[narrator] Over the course of the next week,
the team will take muscle samples
from over 30 individual species
of sharks and rays that are abundant in the area.
This is absolutely gold.
Data gold.
[narrator] The mission comes to a close
and all the tissue samples are sent
to a lab in Florida for analysis.
-[Tristan] Hey, Phil, how are you doing? -[Annie] Hey.
We're on the edge of our seats trying
to work out what you're gonna tell us.
[Phil] We just got the data back
and you are gonna be shocked
-by what we have. -Ooh.
[Phil] So we were expecting this hammerhead
to have eaten a lot of stingrays.
But in fact, less than a third of its diet
is comprised of those southern stingrays
-that we sampled. -[Tristan] Okay.
What is it eating then?
The results are surprising.
This is definitely a shark-eating hammerhead.
The tissue tells us that 70%
of what this hammerhead has eaten
-are sharks. -[Tristan] Wow.
-So a shark-eater? -[Annie] What?
[dramatic music playing]
[Tristan] What Dr. Phil has initially found
with these findings,
it's really exciting
and it clearly shows
that that big female shark
that we took the muscle sample of
is a shark-eater.
-That is actually really surprising. -Yeah. I always expected
that the rays would be like right up there.
[narrator] The diet analysis has revealed
Andros' great hammerheads are eating
just about every shark species
that inhabits the island's waters.
[man] He's working on another shark.
[man] Holy [bleep].
[narrator] And not only that, they're hunting them
in every unique habitat
it has to offer.
[Tristan] There are juvenile sharks
of many different species
year round in Andros.
And maybe this allows great hammerheads
to actually be resident year around
to this system,
which is quite novel
for these migratory species
that typically travel thousands of miles.
We have a lot more work to do
because would've suspected a very different result.
We need to look at some of these other hammerheads
and see if they're following a similar trend.
[Tristan] We know that hammerheads across the world
are probably more likely feeding on stingrays.
They've got that big hammer-shaped head
that's really adapted for pinning down rays.
[Skye speaking]
[Tristan] But we might have found
that these hammerheads in Andros
are actually keeping sharks in check.
There has to be something
that keeps those animals in check,
because if there isn't,
then they may overfeed
on other small fishes
that may impact the health
of the rest of the system.
Hopefully, people will see these hammerheads
and understand that they're truly the guardian
of these habitats and ecosystems.
