00:00A
00:29away from all land, the ocean.
00:36It covers more than half the surface of our planet, and yet, for the most part, it is beyond
00:42our reach.
00:47Much of it is virtually empty, a watery desert.
00:59All life that is here is locked in a constant search to find food, a struggle to conserve
01:08precious energy in the open ocean.
01:11The biggest of all fish, 30 tons in weight, 12 meters long.
01:23A whale shark.
01:32Its huge bulk is sustained by near-microscopic creatures of the sea.
01:48Plankton.
01:49Whale sharks cruise on regular, habitual routes between the best feeding grounds.
02:03In February, that takes them to the surface waters far from the coast of Venezuela.
02:13Others are already here.
02:16Bait fish have come for the same reason, to feed on the plankton.
02:21The whale shark has timed its arrival exactly right.
02:27Oddly, the tiny fish swarm around it.
02:31They're using it as a shield.
02:41Other predatory fish are lurking nearby.
02:48Yellowfin tuna.
02:54They seem wary of the giant.
03:03The shark dives as if to escape from such overcrowding.
03:13Now the tuna have a chance to attack the unprotected bait fish.
03:29But then, back comes the giant.
03:40It has taken a vast mouthful of the bait fish itself.
03:44Plankton, it seems, is not the only food for a whale shark.
03:59Both shark and tuna feast together.
04:03But the tuna must be well.
04:20Even they can end up in the whale shark's stomach.
04:28Predators here must grab what they can, when they can.
04:41For such events do not last long.
04:47The dense shoals on which so many depend gather only when water conditions are perfect.
04:52Many predators spend much of their time cruising the open ocean, endlessly searching.
05:11Plankton feeding rays do so, gliding with minimum effort.
05:23The oceanic white-tip shark, another energy-efficient traveler.
05:32It specializes in locating prey in the emptiest areas of the open ocean.
05:38Patrolling the top 100 meters of water.
05:39The ocean is the top 100 meters of water.
05:41The ocean is the equivalent of the oceanic white-tip shark.
05:43Another energy-efficient traveler.
05:48It specializes in locating prey in the emptiest areas of the open ocean.
05:53Patrolling the top 100 meters of water.
05:57Taste in water is the equivalent of smell in the air.
06:10An oceanic white-tip is able to detect even the faintest trace.
06:19Small pilot fish swim with it.
06:21The shark can find prey far more easily than they can,
06:24and they'll be able to collect the scraps from its meals.
06:33Its long, fixed pectoral fins enable it to soar through the water
06:38with the least expenditure of energy.
06:42This shark has found a school of rainbow runners.
06:51It would eat one given the chance.
06:54But rainbow runners are swift and agile and not easily caught.
07:01So it bides its time.
07:04There's a chance that eventually it may spot a weakened fish that's catchable.
07:12The hunter, endlessly waiting.
07:28Excitement far from land.
07:30A school of dolphin, 500 strong.
07:42They've sensed us food around.
07:47And they're racing to catch up with it.
07:49They've sensed us food around.
07:50And they're racing to catch up with it.
08:11The news has spread.
08:12Now a number of schools are on their way.
08:15They're heading towards the Azores.
08:31Volcanic islands a thousand miles west of Portugal.
08:34The dolphins scan the water ahead with their sonar.
08:36They're close to their target.
08:46The dolphins scan the water ahead with their sonar.
08:49They're close to their target.
08:51They're close to their eyes.
08:53They're close to their target.
08:54They're close to their target.
08:55They're close to their target.
08:56And it's very close to their target.
08:57This is it.
09:01Skadmufen.
09:02It's difficult for a single dolphin to catch the fish.
09:10To avoid wasting energy, they work as a group.
09:15They drive the fish upwards, trapping them against the surface.
09:28And there, other predators await them.
09:35Corrie shearwaters.
09:38They're waiting for the dolphin to drive the prey closer to the surface.
09:45Now the shearwaters can dive down on them, descending to 20 metres or more.
10:02And the dolphins block the baitball's retreat.
10:15The dolphins leave as soon as they've had their fill.
10:18The dolphins leave as soon as they've had their fill.
10:24And, at last, the mackerel sink below the diving range of the birds.
10:28And, at last, the mackerel sink below the diving range of the birds.
10:33The birds leave as soon as we've got their fill.
10:39And the birdsşallah have dropped the ground and returned to the monsieur night.
10:42And finally, they're firing the birds as soon as they've had their fill.
10:48And at last, the mackerel sink below the diving range of the birds.
10:53As the sun disappears, a profound change takes place in the ocean.
11:18Deepwater planktons start to rise from the depths and another hungry army prepares to receive it.
11:48Every night, wherever conditions are right, countless millions of creatures from the deep migrate to the surface seeking food.
12:00A baby sailfish, 15 centimeters long, snaps up everything in its path.
12:16In three years' time, it'll be one of the ocean's most formidable hunters, weighing 60 kilos.
12:25Just now, however, it's very vulnerable.
12:28In three years' time, it's very vulnerable.
12:47These manta rays are giants, eight meters across and weighing over two tons.
13:16The blade-like projections on either side of the head help to steer plankton into the manta's mouth.
13:27Dawn returns and the plankton sinks back into the depths.
13:46If we are to follow, we must use a submarine.
13:59As we descend into the darkness, the pressure builds, the temperature falls.
14:11Below 500 meters, new mysterious animals appear.
14:21Their bizarre shapes help them to remain suspended in the dark space.
14:30Some resemble creatures familiar from shallower waters.
14:34Others defy classification.
14:47All around, organic particles drift downwards.
14:58Marine snow, detritus from the creatures swarming in the sunlit waters above.
15:04The snow is food for many animals here, like the sea spider, a small relative of shrimps and crabs.
15:27Those strange, leg-like appendages are feathered to stop it from sinking.
15:35They can also enmesh marine snow, which it wipes carefully into its jaws.
15:42A saw-toothed eel hangs upright and motionless.
16:05Gazing ever upwards, it watches for prey silhouetted against the faint glimmerings of light from the surface.
16:20Days may pass before prey swims close enough for it to strike.
16:30Farther down still, the blackness is complete.
16:34No vestige of sunlight can penetrate as far as this.
16:43Food is very scarce, and nothing can afford to waste any energy.
16:52A dumbo octopus simply flaps a fin.
16:55No need for the jet propulsion used by its shallow water relatives above.
17:00and tubes above.
17:01animals
17:03on guard
17:06in the
17:16as-
17:21The weirdest in this world of the strange.
17:35Vampyroteuthis, the vampire squid from hell.
17:45Disturb it, and it only retreats a little distance.
17:52Go after it, and it has a special defense.
18:00To see what it does, you must switch off the lights.
18:07The vampire squid has lights of its own.
18:13Bioluminescent bacteria shine from pockets on its arms
18:17to confuse its predators.
18:21Are those eyes?
18:27In fact, there are spots at the end of its mantle.
18:29A bite there would leave the head unscathed.
18:33The threat diminishes, and Vampyroteuthis disappears into the blackness.
18:42At last, the sea floor, over two miles down.
18:52The pressure here is 300 times that at the surface.
19:02It takes several months for marine snow to drift down as far as this.
19:13As you travel away from the rocky margins of the continents, an immense plain stretches ahead.
19:25It extends for thousands of miles, gradually sinking downwards.
19:37There are faint trails in the ooze, signs that even here there is life.
19:47These are what made some of them.
19:57Sea urchins sifting the accumulating drifts.
20:01Shrimps, standing on elegant tiptoe, fastidiously select the particles that appeal to them.
20:13But in the deep sea, as everywhere else, if there are grazers, there are hunters.
20:27A monkfish, almost indistinguishable from the sand on which it lies.
20:48Why waste energy chasing around if you can attract prey towards you with a lure?
20:54Maybe that one was a bit big.
21:15The monkfish can wait, for days if necessary,
21:21until the right-sized meal turns up.
21:28Scavengers, on the other hand, have to move around to find their food.
21:36Crabs can detect the faintest of tastes in the water,
21:39and that helps them locate the latest body to drift down from above.
21:46Eels are already feeding on the corpse.
21:51Isopods, like giant marine woodlice a third of a meter long,
21:56are ripping into the rotting flesh.
22:01Over the next few hours, there'll be frenzied competition
22:06between scavengers of all kinds to grab a share.
22:10Grab a share.
22:11Grab a share.
22:12Grab a share.
22:17Grab a share.
22:19Grab a share.
22:20Grab a share.
22:21Grab a share.
22:22Grab a share.
22:23Grab a share.
22:27Just occasionally, there is a gigantic bonanza.
22:30Just occasionally, there is a gigantic bonanza.
22:53The remains of a sperm whale.
22:57It died five months or so ago.
23:00There's little left but fatty blubber clinging to its bones.
23:07Its flesh has nourished life for miles around,
23:11but now the feast is almost over.
23:19Spider crabs a metre across still pick at the last putrid remains.
23:31A few weeks more and nothing will be left but bare bones.
23:38The crabs will have to fast until the next carcass drifts down.
23:43But not all food comes from the sunlit world above.
23:55The floor of the Atlantic Ocean is split in two by an immense volcanic mountain chain
24:02that winds unbroken for 45,000 miles around the globe.
24:11In places, it's riven by great fissures
24:14from which superheated water loaded with dissolved minerals
24:19blasts into the icy depths.
24:33Clouds of sulphides solidify into towering chimneys as tall as a three-storey house.
24:39At 400 degrees, this scalding cocktail of chemicals would be lethally toxic to most forms of life.
24:52But astoundingly, a particular kind of bacteria thrives here.
24:58and feeding on the bacteria vast numbers of shrimps.
25:14So, beyond the farthest reach of the sun's power,
25:18a rich independent community exists
25:21that draws all its energy directly from the Earth's molten core.
25:25On the other side of the planet, in the western Pacific bordering Japan,
25:46the Dragon Chimneys,
25:49another series of hot vents erupting in the darkness.
25:53Here, more but different bacteria thrive in a similar way.
26:11And here, too, more crustaceans,
26:14but quite different species from those around the hot vents in the Atlantic.
26:24These are squat lobsters clad in furry armour,
26:30jostling with one another beside the jets of superheated water
26:34for the best places from which to graze on bacteria.
26:37These vents, too, like those in the Atlantic, are isolated oases,
26:49so widely separated that each community is unique.
26:52Cross to the other side of the Pacific, to the deep near the Galapagos Islands,
27:08and there are yet other fissures venting superheated water.
27:20One and a half miles down, at a site known as Nine North,
27:25towering chimneys support a spectacular display of giant tube worms.
27:30These vents give off so much energy that some of the worms reach three metres in length.
27:43They're the fastest-growing marine invertebrates known.
27:46All told, over 50 different species have so far been found living here.
27:59The inhabitants of these bustling communities may grow at speed,
28:07but their existence can also be short,
28:10for the vents do not erupt indefinitely.
28:14Suddenly, unpredictably, they may become inactive.
28:17Nine months have passed at Nine North.
28:26What were only recently chimneys teeming with life
28:30have turned into cold, sterile mineral monuments.
28:38Some eddy deep in the Earth's crust
28:42diverted the volcanic energy elsewhere,
28:44and an entire micro-world was extinguished.
28:57In places, volcanoes have erupted to build great submarine mountains.
29:03There are thought to be around 30,000 such volcanoes.
29:08Some, measured from the sea floor, are taller than Everest.
29:12Sheer cliffs soaring to drowned volcanic peaks.
29:20Powerful currents sweep up the mountain's flanks,
29:27transporting nutrients from deep water to water.
29:30towards the summits.
29:33The hard rock provides excellent anchorage for communities of great variety and stunning colour.
29:36Soft corals, several metres across,
29:37several metres across,
29:38collect the marine snow as it drifts past.
29:39Whip corals stretch out into the current.
29:40Whip corals stretch out into the current.
29:41The deep water are more heavy.
29:42The deep, deep, deep, deep, deep, deep, deep, deep water towards the summits.
29:46The hard rock provides excellent anchorage for communities of great variety and stunning colour.
29:53Soft corals, several metres across, collect the marine snow as it drifts past.
30:02Whip corals stretch out into the current.
30:10Giant sponges filter nourishment from the cold water.
30:15A richly varied community flourishes here, sustained by the nutrients and detritus in the icy currents that flow around the peak.
30:45Yet it is all blossoming on an extinct volcano a mile below the reach of the sun.
31:15A noughtous. It spends its days hiding 400 metres down, but as night falls, it ascends up to the reefs to look for food.
31:27Its graceful shell contains gas-filled flotation chambers that control its depth.
31:42It's powered by a jet of water squirting from a siphon.
31:46But it travels shell-first, so it can't see exactly where it's going.
31:59Its nearest living relatives are squid and octopus, which over evolutionary time have both lost their shells.
32:08And the octopus has become one of the nautilus' major predators.
32:12It's a master of disguise.
32:22The nautilus keeps well clear of them.
32:27Its small tentacles carry highly developed chemical sensors, which can detect traces of both predators and prey.
32:35It uses its water jet to dig in the sand.
32:46Because it devotes so little energy to swimming, it only needs a meal once a month.
32:51Got something.
32:52And just as well.
32:53Dawn is approaching, and it has to puff its way back to deeper waters.
32:54And it has to puff its way back to deeper waters.
32:55There's a long tentacle in the sand it's supposed to be on the ground and you can see.
32:56It's supposed to prevent any crew from old people.
32:57It says that fish is too long and you can't stand in the grunt.
32:58But it's an ocean, it's supposed to make a day.
33:00If the sun iselle, it's supposed to be on the sea.
33:01That has to be a little bit cold.
33:02With a sea, it's supposed to be on the sea.
33:03The shore is a grass that has to be on the ground and you can see the sea.
33:04It's supposed to be saw how the sea is coming.
33:05The ocean is tucked away in the sea.
33:06The shore is flowing and it's supposed to be on the sea and it's supposed to be on the sea.
33:07Not as well as that the shore is back to the sea.
33:08of its way back to deeper waters.
33:3230 miles away, shoals of squid are jetting upwards towards the surface.
33:39By night, they seek small fish among the plankton, but they're cautious.
33:52Pacific spotted dolphin.
33:58They're guided by their sonar.
34:00The dolphin, as so often, are working as a team,
34:09synchronizing their attacks to confuse their prey.
34:12As dawn approaches, squid and fish and plankton retreat downwards to shelter in the darkness.
34:26As dawn approaches, squid and fish and plankton retreat downwards to shelter in the darkness.
34:39For more information, is the largest volcano of the sea.
34:49The sea has a ton of sea.
34:52The sea has a ton of sea.
34:56The sea has a ton of sea.
34:58The sea has a ton of sea.
35:01Some of these isolated volcanoes rise as much as 9,000 meters from the seafloor, reaching
35:12close to the surface.
35:14Around these peaks, invigorated by daily sunshine, marine life flourishes in spectacular abundance.
35:31Fish crowd here because the volcano forces nutrients to the surface, encouraging the
35:41plankton to bloom.
36:01An oceanic wanderer, a Mola Mola, stops by to be cleaned by reef fish at the seamount edge.
36:18Butterfly fish pluck string-like parasites from its flanks.
36:30A huge fish lives on jellyfish over 1,000 meters down, where the water is 20 degrees colder.
36:38So a brush-up near the surface allows it to warm up before making more deepwater forays.
36:53The summit of this volcanic mountain rises above the surface of the sea.
37:00It's Ascension Island, 800 miles from any other land.
37:05A welcome, vital haven for long-distance travellers.
37:15Frigate birds spend months continuously airborne at sea.
37:20But at nesting time, they come to Ascension from all over the ocean.
37:30The island's barren slopes of volcanic ash and lava might seem to offer perfectly good
37:35sites for a nest.
37:39But the frigates choose an even more isolated site.
37:45Bosun Bird Island, a lonely pillar just off Ascension's coast.
37:59Frigates are the world's lightest bird relative to their wingspan.
38:04And they can soar for weeks on end with minimal effort.
38:12They seem much more at home in the skies than in a crowded colony on land.
38:18But nest they must.
38:22They come from all over the Atlantic to this their only colony.
38:28There are boobies here too.
38:37To raise their young, seabirds worldwide seek such remote islands.
38:54The farmers also come to Ascension to breed.
38:59A female green turtle approaches the coast.
39:06She's not eaten once in two months.
39:10She may have traveled 1,000 miles from her feeding grounds.
39:15The greatest journey of her kind.
39:25Many others are here too, resting on the sandy sea floor, awaiting the darkness of night when
39:31it will be safer to visit the beaches.
39:40Eggs that were laid a few weeks ago at the start of the season are beginning to hatch.
39:58Most hatchings happen at night.
40:01Now in the light of day, the young are extremely vulnerable.
40:12They must get to the sea as soon as possible.
40:17But their trials have only just begun.
40:34They will drown in the pounding waves.
41:02During the next 20 years, the vast majority will inevitably die.
41:07But those that survive will eventually, as their mothers did before them, return to the
41:13very same beach where they were hatched.
41:18How they find their way back across thousands of miles of open ocean, we still have no idea.
41:24A frigate soars.
41:37Somewhere beneath the surface below, there is the food it must have.
41:43But where?
41:44But where?
41:47Those that fly above the ocean must be able to read the signs of fresh supplies or perish.
41:56A hundred miles from the Mexican coast, and keen eyes have spotted movement.
42:08A hundred sailfish, three meters long, are closing in on prey.
42:19They will only use just enough energy to make their kill.
42:23Never wasting a fin stroke.
42:30Nearly a hundred sailfish have surrounded a single school of baitfish.
42:35It's very rare to see so many of these hunters in one place.
42:42To herd their prey, the predators raise their huge dorsal fins.
43:05A mistimed strike by one sailfish could fatally damage another.
43:09But each continually changes its color from blue to striped to black.
43:14That warns its companions of its intentions and also confuses the prey.
43:23As the shoal is driven nearer the surface, it comes within the range of the seabirds.
43:35Out here in the open ocean, there is nowhere for the baitfish to hide.
44:05On this mountain is a very solid fossilization, and the boat has been a very high-octane sea.
44:08Just so many of them, there is no matter what you can do.
44:30Sailfish live a high-octane life.
44:34To survive, they must find prey daily,
44:38so their entire existence will be spent on the move.
44:54Over 90% of the living space for life on our planet is in the oceans,
45:01home to the biggest animal that exists or has ever existed,
45:10the blue whale.
45:19Some weigh nearly 200 tons,
45:23twice the size of the largest dinosaur.
45:31Despite their great size,
45:33we still have little idea of where they travel in the vast oceans
45:38and none at all of where they go to breed.
45:41.
45:53.
45:57.
46:01The largest animal on Earth feeds almost exclusively on one of the smallest, krill, shrimp-like crustaceans.
46:22They take many tons of water into their ballooning throats in a single gulp and sieve out what it contains.
46:31Every day, each one swallows some four million krill.
46:47Such gargantuan harvests depend on the continuing fertility of the oceans.
46:53But global changes now threaten the great blooms of plankton on which the whales depend.
47:05Once, and not so long ago, 300,000 blue whales roamed the oceans.
47:12Now, less than three percent of that number remains.
47:22Our planet is still full of wonders.
47:26As we explore them, so we gain not only understanding but power.
47:31It's not just the future of the whale that today lies in our hands.
47:39It's the survival of the natural world in all parts of the living planet.
47:44We can now destroy, or we can cherish.
47:53The choice is ours.
47:57For the planet Earth team, just finding their subjects in the vast empty spaces of the oceans...
48:01For the Planet Earth team, just finding their subjects in the vast empty spaces of the open
48:27ocean was often difficult enough. But one of their greatest challenges was to find the increasingly
48:34rare oceanic white-tipped shark and film this fearsome predator in blue water without the safety
48:41of a shark cage. The Bahamas in winter and the underwater team prepares to film rare close-up
48:55images of oceanic white tips in their natural surroundings. Cameraman Rick Rosenthal has been
49:02working in the open ocean for over 30 years and has filmed these sharks before.
49:07It came up, roaring right up to the zodiac and the mouth was full open.
49:13To help him, he's trusting his life to the latest in wetsuit camouflage.
49:17The new Rick Rosenthal. I'm going pelagic jellyfish look to kind of get lost in the big world out there.
49:25Whatever we can do to get an edge. Anything to get close to the animals.
49:32Also on board is cameraman Doug Anderson. He's never encountered an oceanic white tip before,
49:43but he does have a view on what they'll be like. I roughly think of them like little dogs, you know,
49:49and some little dogs are nice little dogs and some little dogs are nasty little dogs and whatever,
49:55you know, when you're in the water you just got to make your presence felt and try and judge the
50:01situation to the best of your ability. Unlike the more familiar reef sharks oceanic white tips are true
50:08ocean wanderers. Once they were abundant, but fishing for shark fins has devastated their numbers,
50:15making them far more difficult to find.
50:24As they prepared to dive, they had no way of knowing what lay in wait below.
50:38It was soon clear that regardless of being nice or nasty, Doug's little dogs were also somewhat camera shy.
50:53Nothing.
50:54Nothing.
50:55Nothing.
50:56Nothing.
50:57Nothing.
50:58Nothing.
50:59Nothing.
51:00As with most dives in the open ocean, seeing nothing is normal, so Rick and Doug persisted in their search.
51:07Reef sharks in those sharks.
51:13Got a big old shark hanging down there, deep, underneath this, deep, deep, deep, good truck.
51:20We may have to reconsider other ways of getting these little oceanics to produce for us.
51:28With the sharks refusing to appear, the team was forced to resort to the tried and tested technique of chumming.
51:35It was time to give the little dogs a bone.
51:39What we've done is we've set up a chum line, which is basically a case of hanging like an onion bag full of the most disgusting offal that you can think of.
51:49The stuff that they couldn't even face put into turkey Twizzlers and waiting for some sharks to turn up.
51:55There's really not much science in it, apart from making sure that the slick of smell and stuff that's going to attract the sharks and hopefully goes in the right direction.
52:07And the right direction for here is not over the reef, but over the blue water, because that's where the oceanics live.
52:14The irresistible smell of rotting fish worked its magic, and soon the first shark appeared.
52:25There was no knowing how long it would hang around, so the divers needed to get into the water fast.
52:32The team could at last get to work.
52:46The oceanic white tip is a known man-eater, a reputation it gained from attacking sailors forced to abandon ship during the Second World War.
52:59Yet this shark seemed almost nervous, wary of the two strange objects that had entered its world.
53:07This was Doug's first chance to get a good look at his little dog.
53:16Amazing.
53:18Totally amazing.
53:22You're such a goddamn doubting Thomas.
53:24You're out of your spoon around.
53:26Door, door, door, door!
53:30So beautiful, I mean, just real oceanic wanderers, those big pectoral sites.
53:39On the next dive, the smell of chum attracted two sharks looking for an easy meal.
53:45How did Rick feel about getting in with them?
53:48Is it a smart idea to stick fish guts and chum, and when you put a diver in, hell no!
53:53Because we've become part of the chum.
53:56Diving with known man-eaters is potentially dangerous, especially when they arrive expecting food.
54:06The secret to staying safe is to watch their every move and to know when to leave the water.
54:12The secret to staying safe is to stay safe.
54:18These sharks appear to be relaxed, allowing Rick and Doug to get rare pictures of one of the ocean's top predators.
54:24But white tips are very unpredictable.
54:29So while the sharks were being nice, the team took full advantage to get some of the close-up shots they needed.
54:36But they were always looking for tell-tale signs that things were about to get nasty.
54:45And if in doubt, there was only one option.
54:48That was exciting.
55:04The final day saw the arrival of three sharks.
55:08Oh, he's huge! Look at the size of him!
55:11This is kind of crazy out here now.
55:18Now the team began to notice a change.
55:24The white tips were becoming bolder and more aggressive.
55:27Their courage seemed to be buoyed by the presence of the other sharks.
55:32Worse still, it was becoming impossible to keep track of all three sharks at once.
55:37And soon the white tips began to show more than just curiosity towards the divers.
55:41Some sharks investigate potential prey by bumping it before they attack.
55:56Rick recognized the signs.
55:59It was time to leave.
56:01He was surrounded and knew the boat had to get to him fast.
56:04That was too intense.
56:12That one took...
56:14One had my fin and was...
56:16One had my fin and was hit me.
56:18I was filming one, the other was just...
56:20Oh, excuse me.
56:24It was down to Doug to get the final shots and get out before his nice little dogs turned really nasty.
56:32That's enough for me.
56:35I'm getting out where the getting's good.
56:38That shark's getting very...
56:40electric and hot.
56:42I tell you, he's got a mouth like that that can take your leg off.
56:46Fabulous animal.
56:48But it's into its feeding mode now and wants to eat.
56:52And I don't want to be part of it.
56:53For Doug, there was always just one more shot to get.
57:08But concentrating on what was in front of him meant he couldn't see what was creeping up behind.
57:13And when one of the cruising sharks changed to attack speed...
57:28It was definitely time to get out and join Rick in the safety of the boat before it was too late.
57:34That was very exciting. It was great.
57:42They seemed a lot more interested than Rick.
57:46I think it's his suit.
57:48Let's go find a bottle of rum, huh?
57:54The oceanic white tips had allowed the Planet Earth team a rare insight into their world.
57:59Now it was time to leave these magnificent animals in peace.
