so welcome to Mythbusters virtual
reality reality reality this is Adam and
know however much you turn around you
won't see me because I'm not here I'm
just doing the narration but the
narration of what well for Shark Week
2015 we tested the myth that sharks are
scared of Orca noises killer whales and
we conducted that experiment on a
shipwreck this video is a
behind-the-scenes tour of that wreck in
full 360 degrees so as we descend you
can already see the reason why we came
to this wreck in the first place there's
loads of sharks if you look all the way
around you you're surrounded by an I
reckon what 25 sharks these are nearly
all Caribbean reef sharks with the odd
nurse shark thrown in there pretty hard
to see now I have to admit I do get a
little nervous before getting in the
water with these guys particularly when
you're on the surface of the boat
looking down into the water looks pretty
scary but once you're in the water what
you see is that sharks are beautiful
graceful creatures it's a real privilege
to be able to dive with them but back to
the wreck this wreck that were over and
out isn't the wreck that we filmed it to
be honest I don't know what this wreck
is and it's so dilapidated it's actually
hard to see what it might have once been
so enough already on that the right we
filmed in is the one just coming into
view in the distance yep here comes now
behind that diver who happens to be our
executive producer checking the place
out prior to our experiments you can see
that somewhat predictably the wreck is
guarded
a bunch of sharks actually not a bunch a
shiver I think that is the collective
noun for sharks
the shiver of sharks like that it's
better than a mouthful or a gulp where
tooth now shivers definitely the best so
now we're swimming directly above the
rack heading towards the stirring this
particular boat was called the ray of
hope it's a pretty terrible name for a
boat that became a wreck lying on its
side at the bottom of the ocean oh cool
look if you look straight ahead you can
see a large wrasse heading into that
tunnel beautiful but anyway back to the
story this ship didn't have some kind of
accident no it was sunk here
deliberately to become an artificial
reef and over the last two decades it
has become colonized by all kinds you
can see stag coral sponges sea fans a
huge amount of life as it can hold on
this wreck now because this is only 40
feet deep it gets a lot of light so it's
a great place for coral to colonize and
it's because of this colonization this
diversity that means an entire ecosystem
completely complex food chains and food
webs can exist and ultimately what that
means is that there are sharks lots of
them a shipper of them although of
course at the moment I say that I
realize there's not any sharks to see at
this point of the boat Murphy's Law we
did this dive the day before our
experiment has a kind of a recce
reconnaissance mission to get familiar
with it and figure out how our
experiment was going to go down but to
see how the experiment itself worked if
you dare you need to check out our other
virtual reality video
