Nevertheless, there are such
astronomic numbers of copepods

that enough will survive to
form swarms of their own

A basking shark

This huge eight tonne fish feeds
on plankton and nothing else

Every hour it filters a thousand
tonnes of seawater through its gills

Numbers of these shark appear when
the bloom is at its peak

and travel along those water currents
where the plankton is thickest

Even so, the supply of plankton
is so abundant

that another group of animals'
is able to share in the feast

- animals that live on the seafloor

Every centimetre of rock is covered
with invertebrates of some kind

- anemones, sea squirts,
Gorgonians,

all trapping plankton from
the passing water

Not all life in the Seasonal
Seas depends upon the plankton

lt's early spring in
British Columbia

Seaweed has started to grow
slowly in the cold water

As the hours of sunlight
increase and the water warms,

these small plants turn
into great beds of bull kelp

The immense 30 metre long strands
have small gas filled floats

which keep them high in the water within
reach of the energy-giving sunlight

Further south the sunshine
is more powerful,

so here, on the coast of California,
the biggest kelp of all can grow

This is giant kelp and
by midsummer each plant

is growing in length by
nearly a metre a day

The main stem is fixed to
the bottom 35 metres below

by a small but immensely
strong holdfast

Fully grown, these gigantic plants
are a hundred metres long

and they form vast marine forests

Great schools of fish find
sanctuary here

These are blacksmith fish

They are plankton feeders
and whenever it seems safe

they head off into open water to
feed where the plankton is thickest

But at the first hint of danger...

...they rush back to the
safety of the forest

Fish are not the only
creatures that shelter here

Californian sea otters gather in the kelp
forest to rest and snooze in safety

To prevent themselves being carried
away into dangerous open water,

where the big predators cruise,

they anchor themselves by winding
straps of kelp around their body

Sooner or later,
they have to find food

and that lies on the seabed
a long way below them

Sea otters, however,
can stay underwater for
