Dwarfed by the vast expanse
of the open ocean

the biggest animal
that has ever lived on our planet.

A blue whale, 30 metres long
and weighing over 200 tonnes

lt's far bigger
than even the biggest dinosaur

lts tongue weighs as much as an elephant

lts heart is the size of a car

And some of its blood vessels are so wide
that you could swim down them

lts tail alone is the width
of a small aircraft wings

lts streamlining, close to perfection,
enables it to cruise at twenty knots

lt's one of the fastest animals in the sea

The ocean's largest inhabitant feeds
Almost exclusively on one of the smallest

krill, a crustacean
just a few centimetres long

Gathered in a shoal,
krill stain the sea red and a single blue

whale in a day
can consume forty million of them

Despite the enormous size of blue whales,
we know very little about them

Their migration
routes are still a mystery and

we have absolutely no idea
where they go to breed

They are a dramatic reminder of how much

we still have to learn about the ocean and
the creatures that live there

Our planet is a blue planet

Over seventy percent of
it is covered by the sea

The Pacific Ocean
alone covers half the globe

You can fly across it non-stop
for twelve hours

and still see nothing
more than a speck of land

This series will reveal the complete
natural history of our ocean planet from

its familiar shores to the mysteries
of its deepest seas

By volume,the ocean makes up 97% of
the earth inhabitable space

And the sheer quantity of marine life

it contains far exceeds that
which inhabits the land

But life in the ocean
is not evenly spread.

lt's regulated by the path
of currents carrying nutrients

and the varying power of the sun

ln this first programme
we will see how these two forces interact

to control the distribution of life
from the coral seas ...to the polar wastes

The sheer physical power
of the ocean dominates our planet

lt profoundly influences
the weather of all the world

Water vapour rising
from it forms the clouds

and generates the storms that ultimately
will drench the land

The great waves
that roar in towards the shores
