this Spike we place right in next to the
dooring that's the
Pinger if you put it on that
bone behind your
ear you can hear it
pinging oh man oh it's quite high
pitched it sounds like a really high
pitched bird chirping in your ear the
sound given off by the tag they're all
on a a frequency of 69 KZ but then each
tag has its own specific frequency space
ID so using underwater microphones you
can hear when different sharks are
nearby there's a little yellow boy out
there which actually has a little
tracker on it so every time a Tagg shark
swings by this is like the shark
checking in yeah it is it is like shark
checking in and over here at the
Neptunes like enough that it connects to
a satellite and email D let us know at
home when the shark is here and at the
same time we also hope to get a tissue
sample from the shark that we tagged why
is that important to grab a tissue
sample couple of uh studies we're doing
are looking at the genetic populations
of the different sharks of the world and
even in Australia we're finding there's
two different genetic populations also
we can work out what the shark's been
eating recently by its tissue wow but
before you can tag a shark you have to
entice it close to the boat well it's
morning and we're just about to have
breakfast but I thought I'd come out and
have a look at the Sharks
breakfast yeah that is what we're going
to be leeching overboard to attra track
the Sharks to our cages we just threw
the bait in and waited about 2 minutes
and a shark came up and grabbed it I was
trying to film the seagulls around the
bait when it hit it was incredible just
unbelievable to see how fast they
arrived here so the sharks are here and
they're
biting the goal is not to feed the
sharks but to pull the bait away from
them before they can get
it oh
man beautiful that's a big shark
as a storm rolled in it was my chance to
observe the Sharks on their own terms
underwater I'm just trying to make a
nice seal with my mask so I don't get
any water in that means heaps of
Vaseline on my mustache feels disgusting
today we've got pretty stormy weather
and the sharks have fired up a bit this
is the weather that suits them for
pration with the sea liines not so good
for us we're all cold and wet but yeah
good conditions to
show thicker even thicker is
gross we're using like half the tub on
me yeah that's how it's got to be have
thank you the storm front coming through
the
best sh will fire up for
you thank you
[Music]
that is
right from the cage you can see the
sharks that have already been
tagged and you get a different
perspective on what it's like to pull
food away from a dark's
mouth in real time you can see just how
fast they can
strike now was a pretty incredible sural
experience just you drop in there and
it's whole another world and it's funny
you don't really feel scared of them
just I don't know maybe it's the cage
but you know they just look so doile and
peaceful so how hard is it to stick one
of those in the dorsal
fin if I can get a shark in really close
and get the right shot um they make it
pretty easy when they swim past the back
of the the platform here there it
is yeah it has to be going slightly
going away it has toally present
so coming still
coming coming up coming
up you come on so close come on so
close with the light fading tagging was
put on hold until tomorrow and that gave
me a chance to talk to the researchers
about why this research is so important
before protection they were hunted for
sport uh they were hunted for their jaws
and they were hunted just out of fear
everybody was scared of sharks you know
the Jaws movie the Jaws phenomenon it
ated an awful lot of of fear of these
animals sharks were mindless killers and
people just wanted them out of the ocean
population numbers basically crashed and
this research is essential to help their
numbers recover we have to find out how
many sharks are out there we have to
find out um where they travel to where
they breed that's one of the Holy Grails
that no one knows where do they give
birth we don't know that either no one's
ever seen them breeding no one's ever
seen him given birth and if you can't
protect sharks in those key areas then
not going to really be able to have much
of an impact across the population as a
whole
that going try to hit
[Music]
it looking good guys looking good
yeah and a tissue
sample it's great the science right you
know we've begin to scratch the surface
with satellite tagging we always thought
white sharks were a coastal species we
found that they able to do Dives well
over a kilometer deep they frequently
dive off the edge of the continental
shelf they go and inhabit niches out in
the open ocean for months and months and
months on end so this whole myth that
they this Coastal creature has been
completely debunked with with the Advent
of this new technology it's one of those
things with these animals that if you
ask a question and and you you you
conduct your research and you answer
your question and then you have five
more questions that have Arisen from
that answer so there a yeah that
obviously there's a lot more to
learn veritasium is supported by
audible.com a leading provider of
audiobooks with over 150,000 different

recommend a book called genius The Life
and Science of Richard Fineman by James
Glee he is one of my alltime favorite
authors so you should really check it
out in fact you can download it for free
by going to
iium or you can pick any other book of
your choice for a 1- Monon free trial so
thank you to audible.com for supporting
me now if you don't know I also have a
second Channel which is called two

thoughts on the world so if you want to
