and their extensive
back up team came to try
and film one of the
ocean's greatest
...change speed
Six to a hundred and fifty
They were here for an annual
event called the run
Millions and millions of tonnes
of
along the coast with
the changing currents
So much food inevitably attracts
masses of predators
and it was this
the team were hoping to film
The run stretches
for miles up the coast
and a was
constantly searching,
looking for of
that would lead them to the action
Once the had
discovered hunting dolphins
it passed on the location
to the boat based teams
And it wasn't just dolphins,
but hundreds of sharks
that were also
attracted by the fish
Before the team put special
tips on their shark sticks
things looked
really dangerous,
these could be used to
the sharks away
. Ready, one,
two, three, go!
Very few people with
the bronze shark before
because we see the sharks in shallow
water during the run only
When we are surrounded
by sharks we feel fear,
then suddenly the
dolphins come...
We hear them before we see them
and then we start to relax
Scientific research on the
run is still in its early stages
and our filming
revealed some very exciting
new behaviour among
Working together in teams,
they were releasing walls of bubbles
to the
into ever tighter balls
This bubble-netting
behaviour allowed
to feed on every last
left behind
while the rest of the
migration continued north
on the
coast of California
Every year a of
arrives to hunt
as they north
through these waters
Our ,
and Tom spent eight weeks
over two seasons trying
to film the action
We had these and
then we started following them
but as you can see the sea's
just got up, it's 30,
35 and we just couldn't
keep up with them
Our team was advised by marine
, Black,
who had spent 1 4 years watching
in ,
but had never seen
a single complete kill
We're been back north again,
because we had a sounding ...
The boat-based team was supported
by keen-eyed
who every day the bay
from the air,
looking out for mothers
and their taking a short-cut
During the spring, when the mothers
and come through,
the north
and when they cross
they're out of the
protection of shore
so there's really no place
for them to hide
and the
are out looking for
these mother-calf pairs
of
can travel at
over twenty miles an hour
and the challenge was trying
to keep up with the action
whatever the weather at sea
We actually were out there
at the perfect time right
before the attack happened
when the killer whales
were still pursuing
the ,
so we, one of our first
times we've seen it
from all the way at the
start till the end
The killers kept up the
hunt for five hours
until eventually the
was so exhausted
that the mother
was forced to stop
and we had to watch as the
came in to finish off
the right in front of us,
just a few metres from our
Killer whales seem to work
in certain roles
and one female
actually positioned
herself between the mother
and gray whale,
she was in there pushing them away,
the other had roles around the outside,
so they seemed to be
really co-ordinated
and that was really the first time
we had a chance to document
that because we had a long time to spend
with the whales that day
they'd taken a mind to it
they could have flipped us over
but on the other hand l think
they were concentrating on the whale
