- Shark!
- What?
- [Jason] Shark!
- Jason!
- The thing I don't understand is,
why are people always surprised
when there's a shark in the ocean?
Like, you're throwing dead
animals into the ocean,
what did you think was gonna pop up?
Flipper?
Hey JQ.
I'm Melissa Christina Marquez,
and I'm a marine biologist.
This is the breakdown.
[lively music]
First up, "Jaws".
So "Jaws" is probably one of my favorite
shark movies hands down.
While it didn't inspire me
to become a shark scientist,
it definitely peaked my interest in what
these animals were all about.
[tense music]
All right. So you see that?
That's called counter camouflage.
So that's when a shark
has two different colors.
It's usually darker on top
and lighter on the bottom,
and it's just for these kinds of purposes,
where it's really hard to see the shark,
even though the water's pretty clear,
and it's not that far away.
It's an amazing tactic
that they use for stealth
and being able to surprise attack a prey.
[tense music continues]
If you look at a shark from above
and you're looking down,
the darker skin color actually
blends into the ocean water
and the ocean ground.
Whereas if you're looking up at a shark
from when you're beneath it,
the white belly actually
kind of looks like
sunlight trickling down.
[tense music continues]
So what you just saw is
actually something really common
in shark science,
which means the shark leaves.
A lot of time we want the
shark to come right at us
and usually it leaves.
But these cages are perfect
for not only seeing sharks under water,
but actually tagging them with something
that lets us actually know
more about its lifestyle.
So where it's been,
where it's going, what it's
doing, what it's eating at,
at what temperature or
light depth it's at.
So a lot of times we actually
have a similar pole to
what you saw here,
with kind of like a dart at the end of it.
And at that dart,
we actually attach a
tag to it and embed it
in what's that dorsal fin,
so that top fin for the shark.
You try to embed it in there
'cause that's probably
one of the toughest areas
to get rid of a tag, so
it doesn't hurt the shark.
It kind of feels like a bit of a pinch,
various similar to what you saw.
You kind of hold on to
the edges of the bar,
kind of wait for the shark to come by,
and you kind of just stab at
the shark and hope it sticks.
Otherwise that's thousands of dollars
that have just stuck to
the bottom of the ocean.
We don't ever inject
our sharks with poison.
It probably wouldn't work.
They have quite high immune systems.
They're not impenetrable,
but I've never heard of
anyone successfully trying
or wanting to try to poison a
shark through a dart method.
[tense music continues]
I love the iconic "Jaws" music.
The buildup of the music is amazing,
'cause you're just kind of sitting there
and suspense being like,
"Right, when's it gonna happen?
When's it gonna happen? When's it...
Ah, there's the big boy"
[screams]
In "Jaws" Bruce, which
is the main character
is a great white shark.
Well sharks sometimes can ram a cage,
especially if the bait is being pulled
really really close to the cage.
Unlike a lot of fish, shark
actually can't swim backwards.
So once they're going somewhere,
they really have not much wiggle room
to be able to backtrack.
So a lot of times,
if the bait is being pulled
too close to the cage
or the shark itself gets
too close to the cage,
it can't go backwards, and
it has to ramp into the cage.
Personally for me, I haven't
had any bad cage experiences.
I have had sharks actually ram the cage.
Will it make a dent like this? No.
It'd have to be a really really big shark.
And so far from all of the
experiences that I've had,
and that I've seen,
no shark can do that
much damage to a cage.
Most of the shark cages
that you see nowadays
actually have the same
exact structure as the cages
back in the 70's and the 80's.
So even back then,
a shark wouldn't be able to
make such a big dent in it.
[tense music]
So that is probably one
of my favorite parts
of the entire movie,
just because you can see
how fake Bruce looks.
[laughs]
But I mean, it wasn't bad for way back
when they kind of made all
the animatronics for this.
[tense music]
The few times I have seen a
shark actually enter a cage,
it's usually a smaller
shark that's actually gone
in between the bars by accident,
and it does not like it whatsoever.
It's actually, most of the
time, pretty terrified.
[tense music]
The ending of this clip
is actually real sharks
on top of a shark diving cage.
It does happen.
They usually do freak out.
And as you can kind of see,
there's a lot of thrashing
as they're trying to get back into
their natural environment,
back into the ocean.
[tense music]
So the reason why he dove all the way down
to the bottom of the
ocean floor is because
sharks are what we call ambush predators.
So they like attacking
something at the surface,
whereas something on the actual ground
can see where a shark is coming,
kind of wedge themselves
into a place of safety.
So it's not so much that
sharks can't go that deep.
It's a lot harder for them to actually
be able to surprise attack,
which is their preferred mode of hunting.
[tense music]
"Jaws" actually helped
kind of cover catalyst
of not only people who
were interested in sharks,
but also people who are
absolutely terrified of sharks,
the author, Peter Benchley
actually regrets writing it
and spent a lot of his time
doing ocean conservation
and trying to right the
wrong of making sharks
not be as vilified,
but unfortunately,
a lot of people still do cite
this movie as one reason as to
why they are so afraid
of sharks and the ocean.
Next up, we've got "The Meg".
[dramatic music]
- Shark!
[screaming indistinctly]
- Megalodon is a very,
very, very extinct shark.
Contrary to what some
things might say out there,
it is no longer in our
oceans unfortunately,
but it was a giant shark
that a lot of people
have likened to look
like a great white shark.
Even though it is actually
more closely related
to other sharks, such as maco sharks.
There's quite a few theories
that have gone around as to why
it became extinct, everything
from climate change,
to a giant meteor, that
their prey item ran out.
So it's really really
interesting to kind of see
what ended up happening
with this big shark,
but there is a giant fascination
with this giant predator.
While we don't know if megalodon
would actually go through kelp forest,
it's actually just been recently found out
that great white sharks,
which are a relative
of the megalodon shark
actually does go through kelp forest.
Previously, a lot of shark scientists,
we all believe that sharks kind
of didn't like that barrier
and stayed away from it.
But new technology such as a
GoPro attached to the top fin
of a shark has actually
showed that they do hunt
through a kelp forest.
So no where is safe.
[laughs]
[beeping]
Oh. Thousands of dollars
right to the ground.
[chain wriggling]
[speaking in foreign language]
I promise you, no shark is big enough
to get an anchor stuck to it
and be able to pull multiple people
and other giant structures with it.
But it's pretty cool to see in CGI
[screaming]
If an anchor got stuck on a shark,
the shark would probably die.
[laughs]
At least nowadays.
Unless it was like a
whale shark or something,
which is one of the bigger
sharks that are out there now.
[dramatic music]
[screaming]
So there's a myth around
sharks that all sharks
need to constantly keep
swimming in order to breathe.
That's not true actually for
every single species of shark.
There are some sharks
that can actually lay down
on the ground and open and
close their mouth in something
that's called the ram ventilation
and force water to come into their mouths,
out of their gills and have the gills
actually extract the oxygen that way.
And so for some sharks like
a great white or a megalodon,
you would have to consistently
keep swimming in order to
breathe and to live.
[tense music]
I'm very surprised that nobody realizes
there's a giant mass
swimming underneath them.
- Shark!
[foreign language]
So, this is what you don't want to do
when someone screams shark,
and that's, splash about
and cause a lot of chaos.
One of the big rules
that we have in order to
swim safely in the ocean is
to always swim with a buddy.
And so, you wanna have a buddy with you
to be able to look around and make sure,
if there is a shark,
keep an eye on it.
But, you also wanna make sure
that you don't cause more
attention on yourself.
And that means, a lot
of splashing at the top,
a lot of erotic swimming,
'cause that to a shark
actually sounds like something
that a wounded fish or wounded
animal would actually do.
So, if you're trying to
get away from a shark,
try to have control of your swimming.
And always remember, it's
not the shark that you see
that's sometimes the problem,
it's sometimes the one you don't see.
How did they lose such a big shark?
There you go.
[chuckles]
[screaming]
So in modern history,
the largest shark that
has ever been recorded
is probably a whale shark.
They get up to 40 feet long
or about like 12 meters.
[screaming]
Would a shark ever
approach that many people?
Depends on how timid the shark is.
There are some species of
sharks that are quite shy.
For example, the hammerhead sharks
don't like bubbles that
scuba divers give off.
And you usually have to like,
hold your breath
or be on something that's
called a rebreather
that doesn't put out bubbles
in order to swim with hammerhead sharks.
But I don't think a shark
would actually go around
and be around that many people
unless it knew that there was food around
and it was really really hungry.
[screaming]
China does have sharks.
Asia in general does have sharks.
Was megadon one of them?
We don't know its full range,
but I don't believe we
found any megadon teeth
or other fossils to indicate
that it has been in that area.
In Central America,
they found what they believe
was actually a megadon nursery ground,
which is another reason
as to why people were like
megalodon is 100% extinct
because its nursery is
above the water now.
Shark ages vary very very widely.
So anywhere from 10, 20 years
to if you're a greenland shark,
you've been around for 400 plus years.
For megalodon shark,
we're not 100% sure though
what its life expectancy was.
[tense music]
What we've just seen with
them lowering the machine,
I'm assuming it's kind of
looks like a hydrophone
which emits like the dolphin
noise and the whale noise.
That's not something that happens.
I've never heard of anyone
using that as a shark repelent
or as a shark deterrent.
Dolphins and whales actually
eat the same exact stuff as sharks.
So if those animals around,
usually a sharks around too.
There have been reports
of dolphins and whales
headbutting and driving away sharks,
but don't always count on it.
Next up, we've got
"Lara Croft Tomb Raider:
The Cradle Of Life."
[tense music]
That was very quick.
All right.
So what she just did is cut herself
in order to attract a shark
to come closer to her.
Usually it doesn't happen
this instantaneously.
And to be honest, if you
cut yourself in real life,
chances of you attracting a shark
are actually very very slim.
You have a bigger chance
of probably contracting
an infection in the water
than you are of attracting a shark.
But anything from a minute
amount might be able to kind of
pick up their senses and perk
their senses and be like,
"Oh, something's bleeding.
I should probably go
check it out and eat it."
[tense music]
This one kind of seems
to be like a tiger shark
but without the stripes.
So, I'm not the biggest fan of it
because it's without the stripes.
You know that noise that the
shark made, that hiss noise,
sharks don't make noises like that.
They actually don't make
noises at all really
except if you're some species
of sharks like dog sharks,
you take them out of the water,
and they're known to bark
as they release air out.
[growls]
That sounded more
cat-like than shark-like.
[thuds]
Yeah. That's a great way
of deterring a shark.
But have you ever tried punching something
underwater before? You're
usually quite slow.
There's a bit of dragged,
whereas sharks they're literally
built to not have drag.
They're covered in something
that's called dermal denticles,
and it actually kind of makes
them quite hydrodynamic.
I probably wouldn't punch
a shark in the snout,
just because your hand might
actually end up down its throat.
Instead, try to aim for the eyes
or even better aim for those
gill slits on the side,
that's where it breathes.
Basically it's almost as
if you were sucker punching
someone in the lungs.
It's gonna take their breath away.
They're not gonna like it.
They're probably gonna go away.
The shark teeth aren't exactly the best.
It doesn't look completely realistic,
especially how the shark kind of like
almost yawns in a way.
[tense music]
After Laura has punched in the mouth
and it kind of shakes
it's head and goes away.
Yeah. Sharks will shake their
head and kind of go away.
But the whole yawning bit
isn't as often seen in sharks.
Some species, yeah.
Tiger sharks, not as much.
[dramatic music]
So it's a really good thing
that she has gloves on.
I don't know if you guys
have ever felt a shark,
but how many of you guys
have felt sandpaper?
Very similar, and it hurts
when you rub up against it.
And that's the same
exact thing with sharks.
So if you rub up the wrong way,
we actually have a term
for this in shark science
called shark burn.
Those fingers, yeah, are
definitely gonna be feeling
the burn quite literally.
Also don't do this.
Please don't ride sharks.
It's so, so bad for them.
Not only are you stressing the animal out,
but it could turn around and bite you,
and that's not good for you.
[crash]
Is it realistic that Laura Croft
held her breath for so long? Yes.
It's actually something
that's called free diving.
And it's quite common.
A lot of people can actually
dive too deep depths
in the ocean without
taking a single breath,
great advanced level skills.
And it's something that
I really wish I had,
but my lungs suck, so I can't.
One of the things that I love
personally about tiger sharks
on top of everything else 'cause
they're my favorite shark,
is the nickname that they
have of trash cans of the sea.
And that's because they're
pretty discriminatory
of what they eat.
Everything from chicken wire,
TNT, suits of armor,
tires, license plates,
they really don't care,
and aren't that picky.
Next up, "Couples Retreat".
- And you're too busy complaining
about your problems
to enjoy all these beautiful little fish.
[dramatic music]
- I wish there was an
experience like this,
where you can float by
something and just feed fish.
But it doesn't exist because
it's dangerous as hell.
- Shark!
- What?
- [Jason] Shark!
- Jason!
- It's all happening Marcel.
- One thing I don't understand
is why are people always
surprised when there's
a shark in the ocean.
Like, in the shark showed
up in your bathroom.
Sure, have this reaction.
But like, you're throwing
dead animals into the ocean.
What did you think was
gonna pop up? Flipper?
- Look [mumbles], it's
circling our lives right now.
- Do not move, do not fight.
- Move, but gently and without panic.
- Marcel, I need you to take
the french out of your mouth,
and tell me what to do.
- Don't let them see your fear.
- Don't let him see your fear.
That's very good advice
because sharks can actually
detect your heart rate going up.
So do try to stay calm.
- Don't worry these are only lemon sharks.
This is all part of the course.
- So supposedly these are lemon sharks.
But they don't look
like lemon sharks to me.
It actually looks more like
some sort of reef shark.
The size of the shark for
those smaller reef sharks
is pretty accurate.
If not, maybe a little
bit on the smaller size.
Don't do that.
Don't spill the chum on your mate.
Don't do that.
For those who don't know,
chumming essentially is
what we kind of just saw
of just having a bucket full
of blood, fish guts and oil
and bits of fish that
you kind of like take out
one by one and kind of get
it in a nice soupy mixture
to attract sharks to come closer to you.
It's not something that
we tell people to do.
But also scientists do use it
for scientific research purposes,
such as tagging a shark or doing a fin ID.
What he should probably do
is get out of the blood.
[laughs]
- No, just get out of
their chum, but slowly.
Swim slowly out the chum.
Slowly.
- That is very good. I like him.
I like this French dude.
He is giving good advice.
Get out of the chums slowly. Don't panic.
- They're torturing me.
They they're playing.
They're slow playing me.
[speaks indistinct]
- Swim slowly.
- That is not staying
calm. That's panicking.
- Swim slowly out the chum.
Slowly. Yeah.
Stop.
- The stop and start tactic,
I don't really know if
it would help or hurt,
because if the shark wants to go at you,
it doesn't matter if you stop,
it's gonna know you're there.
It's not going to be like,
"Oh, it's stopped moving.
I don't know where it
went all of a sudden".
Like, it knows you're there.
- Go to shore. It's too late.
They've got me. It's
only a matter of time.
- There's no, no sharks around you, honey.
- If you notice in that last bit
where he's kind of far
away from the sharks,
all of them are just in that one bucket.
And that's all that they
were really curious about
was the blood. Would did
that happen in real life?
Possibly.
Word of the advice is,
just don't have a bucket of
chums slammed on top of you
because you don't want
to take any chances.
Next up we've got "47
Meters Down: Uncaged".
Alright. So a few things
right off the bat.
They're supposed to be in fresh water.
And, there are some sharks
species that are in fresh water.
They don't look like this or get that big.
And it seems like the shark
is also supposed to be blind.
That's why it's got that
milky covering over its eyes.
Never really seen that in
many shark species either.
The only sharks that I've ever
seen that are partially blind
are actually greenland sharks
when they have these little parasites
or copepods off of their eyes.
And it does kind of give
them like a milky look,
but definitely not like that.
So far seems pretty unrealistic.
But from what I'm seeing,
it looks like it has five gill slips.
So that's anatomically correct.
- Oh my God. Two sharks.
- Are there a lot of
sharks that are in caves?
Not that I've heard of.
A couple of years ago, it
actually made international news
that there were some sharks
that were found in an
underwater volcanoes.
Even though it's very unrealistic
that there's this many sharks,
let alone in a cave area, who knows?
Maybe we just haven't discovered any yet.
[screams]
[dramatic music]
The shark doesn't really
look like any shark to me.
[laughs]
It seems like someone took
a bunch of different pieces
of sharks and made it into
this zombie looking shark.
It almost looks like a
mako or a porbeagle shark.
But that's just like their little face
and their body feature looks like that.
[laughs]
[tense music]
[screaming]
- Get me out of here!
- You wouldn't really be able
to see a shark coming toward you
if it's coming from underneath.
Depending, I guess, on the life jacket.
If you've got a really puffy one,
you're lucky to see your
own toes, let alone shark.
So as the people are treading around,
you can kind of see the sharks
are swimming around them,
circling them.
That is something that sharks do.
What they're doing while
they're circling you
is not only using their
ampullae of lorenzini
to figure out, like, are
you like, are you alive.
Or are you giving off
electrical little minute pulses.
But they're also looking at you as well.
That's what they're doing with their eyes.
Mostly is looking at
you to figure out what
shape you are and if your food,
or if there's something that
they've never seen before.
This shark is blind.
So I don't know what the heck it's doing.
[laughs]
[tense music]
Well I haven't seen
any research being done
on what attracts a shark
more in regards to noise.
Is it more at the surface
or more underwater?
But I would think at the surface is just
because you have that splashing noise
that can kind of travel farther, I think,
than say underwater,
you don't have as much.
And usually when you've got
some sort of injured animal,
they do kind of float up to the surface.
However, because she slammed down,
that noise probably did attract
them to the source of it.
They saw her or sensed her there
with their super power blind shark powers.
[growls]
Those are some terrifying
last moments for her.
There have been some cases,
especially for surfers,
that have shown the shark
actually go for the rib area and whatnot.
So that is possible. Yes.
I have never been bitten by a shark,
but while I was filming for
"Shark Week" a few years ago,
scuba diving underwater,
I was actually bitten by a
10 foot American crocodile,
and I've got the scars
in the story to prove it.
That actually was so deep
that I could fit my
pinky up to about there
on every single one of those bites.
I guess you can kind of take a
little bit of solace in that,
knowing that a person who
works actively with sharks,
pretty regularly has
never been bit by a shark.
So your chances are quite low.
[growling]
Will two sharks fight over a person
and then tear them in half like that?
Probably not, very unrealistic.
Usually there's kind of
like a hierarchy for sharks
when it comes to feeding.
Oftentimes if one is kind of nibbling,
the others kind of stand back
until it's engorged itself,
and then they go in, in
that hierarchal order.
They respect their elders
and their big sharks.
Next up, we've got "Deep Blue Sea".
I've never seen a setup like
this for a shark before,
I will say that.
So we don't have any underwater labs,
like is shown here.
But we do have some lab
spaces that are near water
so we can actually bring sharks
into an enclosure similar to this,
but not with all the
high tech kind of gear.
We do have some sharks
that we keep in enclosures
and do tests on, medical tests even,
where we take blood, hemoglobin
and some skin tissues.
Our labs might not look like this,
but they're still pretty cool.
- Membrane integrity is improving.
They are firing.
They're firing!
- If anything's gonna be
the most unrealistic part of this movie,
it's gonna be that its scientific results
coming out that quickly.
Yes, sharks are actually
used in for medical purposes.
Not so much all-timers to my knowledge,
but in other ways they're
more predominantly used.
It's called bio inspiration.
Using things that we find in nature
in other parts of our life.
For example, sharkskin
has actually inspired
not only swimsuits that
were banned in the Olympics,
but also the design of airplane wings.
So, medically there is
quite a lot out there
that sharks are starting to help with,
especially because a lot
of people are curious
as to how their immune system holds up
and how powerful the immune system can be.
- Introducing two CCS of
the protein component.
- So while they scene does show sharks,
it's not all about shark science.
It's mostly about the medical side
and what they can use sharks for.
But that's actually not everything that
shark scientists can do.
We have kind of our
own different paths of,
or niches if you will, of expertise.
And so for me, completely
different from this.
I actually look at habitat use of sharks.
So figuring out why
sharks are where they are
using technology such
as drones or something
that is called BRUVs,
baited remote underwater video cameras.
Essentially, it's like a GoPro
with a little treat bag at the end.
It entices the shark to
come a little bit closer
so I can get a look at it,
idea and figure out if that
habitat has any significance,
such as a nursery.
[gentle music]
- They're firing.
They're firing!
- Shark brains are really hard to come by
because you need dead sharks for that.
Even though it's not my expertise,
there are some people who are out there
studying these brains.
But it's such a complex organ.
We barely understand our brain.
It's really hard to wrap our
minds around another animals'
very complex brain
[growls]
Sharks, they can swim actually
that kind of side to side motion.
So it is very important
that you tie your sharks down properly.
Now, are you supposed to
use those kinds of ropes?
No. There's special ropes
that we use for sharks.
Yeah.
The rope is not well-placed whatsoever.
So a lot of times for ropes,
if we're gonna loop one around the shark,
we also try to loop one around
one of the fins as well,
so it doesn't swim away without us
making sure it's good to go.
So the rope job here is quite bad.
But sometimes we actually
put covers over the eyes
so it doesn't freak out.
You actually do this with
quite a lot of wild animals.
And some I'm a bit surprised
if they did have it on here,
but also not that surprised
because it's a movie.
That the guy is in the water with him
and the shark isn't actually
doing anything to the guy
can be a bit normal,
just because maybe it's
out of the shark's vision.
It doesn't really care that much about it.
But because that one guy
was in front of its vision,
that's why I kind of went
around and went chump.
Because it's like, "Oh, I see you.
I'm unhappy. I'm gonna
take it out on you."
Yes, it does look like a mako shark.
Congratulations. And
even got the teeth right.
'Cause the teeth,
they almost look like needles
and they're pointed backwards
'cause they eat a lot of slippery fish.
And so the teeth pointed backwards help it
not move around as much.
So good job people.
Do you see how there's
multiple rows that is accurate?
Quite a lot of shark species
do have those rows of teeth
that when one tooth in
the front falls off,
another one kind of is
like a conveyor belt,
it comes forward and takes
its place. I think on average,
it's like 30,000 though teeth
in a lifetime, which is a lot.
They don't get this big as you can see.
It seems like it's a pretty
big enclosure that it's in.
And compared to the man that
you kind of see on the edge
that was in the water with this shark,
that's just not possible.
Sharks are pretty smart as
they as they kind of are.
They've been around for millions of years.
But as we've kind of said,
their brains are something that
we're just beginning to understand.
So trying to kind of equate smartness
to a shark is really hard to do.
But, we know they're
really excellent predators.
And what they've been doing
for a while has worked.
I don't know if making them smarter
would make them more aggressive.
I think it might make them
more cunning hunters though.
And might make them have
a little bit of a temper
and be fed up with people
poking them next up.
We've got "Ace Ventura: Pet Detective"
[slow music]
That is not usually an outfit
we marine biologist wear
when will we go to feed our pet sharks.
- I've got a little snack for ya.
[whistles]
[growls]
[screams]
- So in that small tank, probably
is not going to be able to
breach upwards kind of
how you saw in the film.
It might be able to like lift
itself up a bit, but not much.
It does need a little
bit of room to be able to
propulsion itself up,
to propel itself upwards out of the water.
Most times when a great
white shark is reaching,
it usually goes like
this or like that way.
There's a lot more splashing,
a lot more area needed for an
animal to be able to breach.
Definitely can see that it's
a great white shark there.
Would you have it as a pet? No.
Not even aquariums are good
at keeping great white sharks
in captivity.
In fact, Monterey Bay
aquarium is one of the few
that has actually kept them.
And for a very short amount of time,
it's very very hard to keep
great white sharks in captivity,
mostly because they keep ramming
into the edges of the aquariums.
They do not like captivity whatsoever.
Just the tidbit.
While it's not illegal to own sharks
in your own personal aquarium,
it's actually quite hard,
not only a, to get a shark
such as a great white to keep,
but also some of them are
protected, so you can't own them.
And it's not really the smartest thing
you want to do anyways.
Not only does the animal get
a lesser quality of life,
but you're gonna have to
pay up all a lot of money
to keep up with how much
a great white shark feeds.
- Here, Snowflake.
I've got little snack for you.
[whistles]
- One thing with the shark
wouldn't be able to just
automatically know is that Ace Ventura
is actually holding a fish.
You need to throw a few in there
in order to get the sharks attention
and it realizing that you
actually have fish in your hands
and that you're feeding it.
[screams]
Now, the way that you see Ace
Ventura kind of flailing about
and being held in the jaws
of this great white shark,
there is no way he would
be able to walk away
without any injuries whatsoever.
Very very unlikely that would happen
and probably impossible.
Don't try it at home to
prove right or wrong please.
Next up, We've got "The Shallows".
So I will give props to the "Shallows".
They have a very realistic
looking great white shark.
There's no denying it.
I'm tired of seeing sharks
that look more like dolphins
or as someone has like Frankenstein picked
and put sharks together
and made it look like
some brand new species
that I would never want
to see in the dark ocean,
let alone in a dark alley.
[slow tense music]
[stings]
- He didn't like that 'cause
it seems like jellyfish.
- Okay.
A great white shark would
not be just chilling
in the coral reefs.
They are more of open ocean water animals.
So the likelihood of them
running into a coral reef
and still sticking around in
order to get one piece of prey,
very, very unlikely.
[slow music]
You see a lot of jellyfish in this movie
and this specific scene. There
can be a lot of jellyfish.
So many in one area,
actually, that it's just,
I mean you can even see water.
It's a big gnarly.
They don't glow like this.
Either this like ethical angelic thing.
That's very rare.
[laughs]
Some species do glow.
Some of them have like
little rainbow tendrils,
which is really cool. Like
can glow, but like that, no.
[slow]
[screams]
Ooh. Yeah, that's gonna hurt.
I've been stuck by jellyfish before,
like in the face and stuff. That hurts.
[growling]
Okay. So what you see here,
the shark kind of like swimming
away from the jellyfish.
It hasn't been like
scientifically tested or anything,
but I can tell you that sharks
don't care about jellyfish.
If they really want something,
they will swim through the
jellyfish to get to it.
They've got pretty tough skin
made out of dermal denticles,
which actually translates to tiny teeth.
It helps reduce pain as well as like drag.
You can see it's doing
more pain and damage to her
than it is to the shark.
Great white sharks, believe it or not
do not like as orcas.
Orcas are a big time predator
for great white sharks.
Usually the orca is actually
target the sharks liver
and sometimes it's claspers,
which are the male reproductive organs
for great white sharks.
Once a great white shark
has been bitten by an orca,
usually the great white
sharks in the surrounding area
will leave for a little bit.
So, become best friends with an orca.
Call out for them when a
great white shark is nearby
and who knows, maybe
they might help you out.
[dramatic music]
Oh yeah, she's got some serious
sharp burns right there.
She stabbed it.
[laughs]
Give her props for that. It is very hard.
Like, it is hard to get a tag
through the dorsal fin of the shark,
let alone stab it with like
a rusty [speaks indistinct].
So I won't give Blake
Lively props for that
to be able to stab through
a shark's very tough skin.
When she fell on the shark,
she's probably gonna be
covered in that shark burn too.
So I feel really bad for her.
She's in a world of hurt right now.
She's gotten jellyfish stings.
She's been just absolutely
obliterated by coral.
And now she's got shark burn.
She's not having a good time.
[tense music]
Would a shark jump up to
get a prey item like that
once it's on some sort of
like structure or whatever?
Possibly. I've never seen it happen.
None of my colleagues
have ever seen it happen.
So I want to say very unlikely
that this scenario here is realistic.
[tense music]
Great white sharks are
cosmopolitan animals.
That means you see them
at all sorts of oceans,
of all of our oceans really.
Would they be this close to the shore?
Possibly.
Especially if there's a dead whale carcass
and this is actually something
that can happen. Yes.
Would it sit around for tons
and tons of time? Probably not.
And this has happened
before and like Hawaii
and other Pacific islands.
And it does attract sharks to come closer.
And usually officials do say
stay away from the dead whale
and the surrounding area,
because it does attract sharks.
I haven't heard of anyone
being bitten by a shark
when there was a whale
carcass in the area.
But I think that's
because most people have
common enough sense to not be
in the water with something
that is essentially
ringing a big dinner bell.
[growling]
[dramatic music]
Sharks are definitely not vindictive
as it has been portrayed in this movie.
They don't hold a grudge. Promise.
As you can see the portrayal
of sharks in movies,
isn't always the best.
They need a little bit of a PR manager
because even though they're portrayed
as these scary monsters,
that's not actually the truth.
You don't have to worry about
an ocean filled with sharks.
Instead, you should be worried
about an ocean without them.
Thanks so much for watching
this [mumbles] with me.
I'll see you next time.
