By summer it was half grown

Now at last, in the late autumn
- it's nearly ready to hatch

A fully formed miniature
shark swims free

This year's plankton will soon die
but the young dogfish

is so well developed that it can't hunt
immediately for larger prey

The days are getting shorter now

ln British Columbia the
water begins to chill

This bizarre looking creature
is searching through the kelp for food

This is Melibe - the hooded sea slug

lt catches plankton with
its net-like head

As winter approaches
plankton is becoming scarce,

but Melibe is an assiduous searcher

lt can swim

lt flaps away to look for
a better feeding spot

But its search is becoming
increasingly difficult

Within the next two weeks most
of the plankton will have disappeared

As the sunlight becomes
ever more feeble

- the kelp starts to die,
gradually rotting away to nothing

Soon it will be winter

But 9,000 miles to the south the sun
is rising on a new spring day

The southern hemisphere too
has Temperate regions

- and now the plankton is
beginning to bloom around Tasmania

Just as in the north,
the Southern Seasonal Seas

also have areas of
rich green water...

...with their own kelp forests

...and their own swarms of plankton

Some of the inhabitants of these seas
live only in the southern hemisphere

This is one of them - the handfish
- that strolls around on modified fins

But when needs must
- it can resort to tail power

Every summer visitors come
to the shallows around Tasmania

These are Australian squid
- about half a metre long

They are here to breed

The larger males compete for
the attentions of a female

displaying towards her and to one
another by putting on a ballet,

during which they continually change
the colour of their costumes

Eventually they form pairs

A male passes a packet of sperm
across to the female

After the eggs have been fertilised,
they are deposited in tough,
