These
males to kind of feel each other out
and figure out who are the males
to stay away from
and who they can potentially
be harmed by,
They're bigger and more
dominant than other males
that they actually can overcome
The biggest lesson that
l've learned is that
if you want to look at harbour
seals and understand their behaviour
you have to look at them
Almost everything interesting
these animals do occurs
Hundreds of miles to the north,
off Prince William Sound,
another Blue Planet team came in
search of one of the least known sharks
in the world -
These unusual relatives of
the
have never been observed
behaving naturally
and we were keen to try
and get unique
images using a remote camera
attached to a pole
Director, Hugh
the action with a monitor on the surface
and film something very new,
and also it just fitted in
so well with our story
because the whole theme of
the
is the
and this story is totally
You know, the
waiting for the salmon
to move in to
and then they move in
Obviously with these sharks we've
hoping that we're going to get them
actually behaving naturally
and sort of fishing
amongst the salmon in the
thick numbers that we've told
The timing for us to come here for
the
because for most of the year
the scientists think that
they're out feeding away in the
but they follow the salmon in and
the salmon only run in for a few weeks
or maybe a month
or so during the summer
lt's not just the sharks
that are after the salmon
There's a big fishing industry here
and we were advised by
Ken
who help him catch sharks for science
resource for the state of
There's become a large interest
in sport fishing for them,
it's kind of becoming big news
for game fishing
and the state and federal
government are very interested
in managing this shark species
before the population
begins to decline because
of the
Catching and tagging
a 4 metre shark is hard work,
but Ken hopes it might
provide vital information
about population size
and where the sharks go
They have only ever been
seen here off
and then for just one
month each year
The rest of their lives
remains a mystery
Alright. Yeah that'll be fine,
looks good
This is often the only close-up look
that Ken ever gets of his shark
and he was as
to see what pictures would emerge
from our patient work with
the camera on a pole
This is a selection of like,
about three minutes of some
of the good stuff we got
This kind of activity is what
l don't get to see
Even when l look over the side
of the boat l'm getting a top view
and what l don't get is
the side of the animal
looking up
those views
What's the distance from the camera?
That's nice
That there, when he's out there,
that's probably 1 0 foot is
when you start to see them
They're probably seeing that
camera at 30 feet or who knows
but they're certainly adapted to that
environment where ours is not and so...
Do you think from that that
they're very visual predators?
Yeah
By exploiting the sharks'
acute visual sense,
we hoped to
get some more powerful images still
what you're doing either in the boat,
moving it along you know
you've got something visual
that's going through the water
You can't really see it when
you're not getting a video shot
like this where that fish comes in,
it turns its head to it
and then turns away, it's that curious
and
and
comfortable enough to go for it
lt's a new look, it's, this is
that so little is known about
and very few people have had the
opportunity to see them
