In Hammerhead Sharks Up Close, we're
0:01
bringing you right into the world of the
0:04
Hammerhead.
0:08
We went to an incredible archipelago
0:11
called the Rei Heekiedo Islands. You get
0:13
10 points if you can spell that without
0:15
looking it up. It's a magical group of
0:18
islands that have a population of
0:20
scalloped hammerhead sharks.
0:21
>> Oh, look. Hammerhead sharks are
0:24
incredibly shy.
0:25
>> Surely there's hammerheads nearby. So,
0:27
you really have to play hide-and-seek
0:29
with them.
0:30
>> Positive pressure test.
0:32
>> A key piece of equipment we used was
0:34
called the rebreather. Unlike
0:36
traditional scuba diving equipment that
0:38
makes bubbles, a rebreather recycles
0:41
your air. So, when you breathe out, a
0:43
bit of oxygen is added and then that
0:45
same breath is given back to you through
0:47
another hose.
0:48
>> That way, we got to go that way.
0:51
>> And that is useful for two reasons.
0:54
Because you're recycling your air, you
0:55
can stay down way longer. you can become
0:57
part of the environment
0:59
>> right inside the school.
1:02
>> The other reason is that you're not
1:03
making noisy bubbles.
1:07
>> The way they just appear out of the
1:09
gloom, it's so ethereal.
1:12
>> I've been fortunate enough to film
1:14
hammerhead sharks all around the world.
1:16
I have never had an experience with
1:19
hammerhead sharks like the one that I
1:20
had at the Revy Hickey Islands. And that
1:23
is a dive that will be etched into my
1:26
memory for a very long time.
