Then a quick trip to the surface for a refreshing gulp of air.
Perhaps he should have stayed hidden.
The lungfish waited months to breed again.
Now he is woken to a world of familiar dangers.
Adapted for life in and out of the water, he's built for survival.
Unfortunately so is the shoebill.

Kate look, a little more over here.
I mean a little bit of a chase.
So why on earth are these animals, these very special Irish animals hanging out at the airport.
Well, the question, as ever, comes down to habitat.
And the fact the wildlife will take an opportunity whenever it can get it.
And the airport as it turns out is fantastic habitat for these hares.
I guess it's got all of this, short grass, it's never sprayed, it's only mowed once a year.
So this is perfect grazing for these animals here.
But also, despite the noise and all of the aircraft moving about, this is a place where they're relatively
undisturbed, because you don't get people out here.
You certainly get people with dogs, and of course there are natural predators there will be foxes here, but relatively few bird predators, because birds will positively be discouraged from the airport.
The hares, they don't encourage them but they don't discourage them either.
So it's a very harmonious relationship here.
These hares, look more like mountain hares than they do the sort of big hairs that you're used to seeing in the grasslands of places like Norfolk.
They've been here for 30,000 years isolated.
So the current thought is that they are genetically distinct and will be classified as a subspecies of the mountain hare, but still they are not brown hare.
I was just gonna say brown is completely wrong because they're actually quite gingery aren't they?
Because, you know, red headed hares.
But look at the ears, Kate.
I mean the ears are much much shorter than a European brown hares' ears.
And they're smaller animal and their tails' different too.
Their tails got a lot more white.
It's very distinct tail isn't it.

Arctic hares.
Like the wolves, they stay white throughout the short summer.
While they can run, they can't hide.
And to make matters worse, now is the time they have their young.
A mother hare risks feeding her leverets　for only a few minutes each day.
Her white colour makes her only too conspicuous.
When wolves are spotted, Mum runs for it.
That makes sense.
Her leverets have a better chance without her.
Unlike their mother, the leverets are camouflaged.
They're nearly impossible to spot, even when right upon them.
What they must do　is keep their nerve.
When forced to break,　they can still give the wolves a run for their money.
The leveret hunt may appear an unfair contest.
But for every one caught, hundreds more remain hidden.

This is the closest that I've ever been to a brown hare and been able to move about and speak.
I can actually see this one nibbling the glass.
It knows perfectly well that I'm here.
And it's a fantastic opportunity to get close to this animal and have a really good look at it.
I don't need binoculars at all.
I can go straight into its eye.
And I'm sure you can judge immediately that this is a completely different animal to the rabbit.
It's much larger.
It's got much longer ears proportional to the body size and, although it's difficult to discern at the moment with this animal sitting, they equally have much longer hind legs in proportion to that body size than rabbits as well.

The macaws' detailed knowledge of the forest tells them just where to go.
Along the riverbank are special sites where a natural remedy can be found.
Smaller parrots have beaten them to it.
Mealy parrots are joined by rose crowned parakeets.
The macaws are naturally cautious.
They use the little parrots as bait to see if any predators are around.
These parrots are here for the same reason as the macaws.
The healing qualities of the clay.
This special mud neutralises the toxins they've acquired through a less than perfect diet.
The macaws are still too nervous to join the gathering.
Monkeys have arrived, putting them on edge.
But the spider monkeys are more a distraction than a danger.
He weighs up the risks, and takes his chance.
Time's up for the flocks of smaller parrots.

Upwelling currents filled with nutrients make the Bering Sea one of the richest in the world.
In early June, thousands of capelin fish wash onto the shores, drawn by the instincts to mate.
Within a week, most of the fish will be dead, more nourishment for the living.
With the sea so full of fish, it's not surprising to find predators who specialize in catching them.
Each summer, tufted puffins arrived on the islands off Kamchatka to nest.
On (ぜんぜんわからん！) island alone 100,000 puffins catch millions of fish each month.
Puffins lay a single egg that must be incubated for two months.
While one parent cares for the egg the other heads for the sea.
Puffins are awkward fliers and need cliffs to get airborne.
If once they dive underwater, the puffins truly fly.
And become master predators of the sea.
In the world below the waves, the otherwise awkward puffins perform a graceful water ballet.
