00:10♪♪
00:20♪♪
00:30♪♪
00:40This is a bottlenose dolphin.
00:43♪♪
00:47Its brain is one of the largest in the animal kingdom,
00:52even larger than our own.
00:55♪♪
01:04It's thought to be one of the most intelligent creatures on the planet.
01:08♪♪
01:16Dolphins, along with their larger cousins, the great whales,
01:23live in a world entirely alien to our own.
01:27♪♪
01:33It's hard to imagine what's going on in their minds.
01:37♪♪
01:51Trying to reveal their secrets,
01:53scientists who have dedicated their lives to understanding them.
01:57I think we could talk with the dolphins within five years.
02:03And taking us closer than ever before,
02:07two of the world's top underwater cameramen.
02:11♪♪
02:15Fantastic. Today is the best day of my life.
02:20It's a peach.
02:22That's one of the most awesome things you can see anywhere.
02:26Like us, whales and dolphins are big-brained
02:30and live complex social lives.
02:34♪♪
02:39But just how intelligent are they?
02:42♪♪
03:00Off the coast of the Bahamas lies a tropical paradise.
03:05♪♪
03:11These calm, clear waters are the perfect setting
03:15for one of the world's most in-depth research projects
03:18on wild dolphin communication.
03:21♪♪
03:25The degree to which an animal can communicate
03:28is an excellent measure of its intelligence.
03:32So how do these Atlantic spotted dolphins perform?
03:36♪♪
03:45Behavioral biologist Denise Hertzing
03:48is a world expert on dolphins and dolphin speak.
03:54Well, they make echolocation clicks, so they...
03:57Which are?
03:59Hey, she's good, that.
04:05Denise has spent the last 26 years
04:08studying the local dolphins and knows each one personally.
04:13Hey, it's Stubby! Stubby!
04:15Come here, let's see Stubby all year.
04:17Her goal is to understand how they communicate
04:20with sound, touch, and body postures.
04:24She does this by recording their behavior
04:26using a specially designed hydrophone and underwater cameras.
04:33Later, she analyzes the footage and sound recordings
04:37in an attempt to understand just what they're saying.
04:41♪♪
04:49Thanks to Denise's enduring relationship
04:51with these dolphins,
04:53cameraman Doug Allen and Didier Noirot
04:56have a unique opportunity
04:58to capture the huge range of dolphin communication.
05:03Things that are good to do are to make eye contact
05:06if they're interacting with you.
05:08Don't turn upside down.
05:10That's a signal of a mating or aggression.
05:14Okay, here's the big tip.
05:16Whoever behaves themselves best,
05:18and shows the best etiquette with the dolphins
05:20is probably going to get the best footage.
05:22So that's your challenge.
05:25Yeah, we're ready!
05:28♪♪
05:38As they get in the water,
05:40the team are confronted by a family group.
05:45Including a mum and her young calf.
05:56In the dolphin world,
05:58a mother will look after her calf for up to five years,
06:02giving her plenty of time to teach everything she knows.
06:07When mum and calf separate,
06:09they keep in contact
06:11by making their own unique signature whistle.
06:23Dolphins also learn the signature whistles
06:25of the others in their group,
06:27so they can learn how to communicate with each other.
06:32Besides humans, dolphins do seem to be
06:34the only group of animals
06:36that have individual names for each other.
06:49In two years' time,
06:51the team will be able to learn
06:53how to communicate with each other.
06:57In dolphin society,
06:59communication also has a darker side.
07:19These are younger males, they're not so old,
07:21so they're probably learning.
07:24And it's usually when they're hyped up
07:26and they're getting ready to chase and fight.
07:43This time, as they enter the water,
07:45there's a cacophony of clicks and whistles.
07:49Trouble is brewing.
07:54Male dolphins form small gangs,
07:57synchronising their movements and vocalisations.
08:05When they're together,
08:06they seem to create their very own gang whistle.
08:12This gang of male teenagers
08:14are chasing and fighting each other.
08:19They're chasing Amanda, a female Denise knows well.
08:24They're trying to impress Amanda
08:26with their synchronised moves.
08:28She doesn't seem too happy with all the attention,
08:31fending them off with high-pitched squeaks
08:34and slapping her tail.
08:37They keep buzzing her with ultrasound
08:40to check she's in season.
08:46But now, they've got competition.
08:53It's a gang of older males.
08:58They've got a lot to learn.
09:01It's a gang of older males.
09:09The battle over Amanda has begun.
09:31Down on the seabed, the two gangs go head-to-head.
09:43Completely ignored by the dolphins,
09:46Didier gets a rare chance to record this intense showdown close up.
09:52Each side is posturing and jaw-clapping in synchrony
09:56to make them appear bigger and stronger.
10:03Didier is the only male in the group
10:06who has a chance to show off his skills.
10:11He's got a good sense of rhythm.
10:14He's got a good sense of rhythm.
10:17He's got a good sense of rhythm.
10:21It's intimidation based not on violence,
10:25but on a high level of communication.
10:50Then suddenly, the fighting stops.
11:01The old boys have seen off the young guns.
11:05Their argument was clearly more persuasive.
11:10There's lots of action going on there.
11:15They came all together in mid-water,
11:19Sometimes you could see them,
11:21this big curved posture with the beak open.
11:24That's really extreme aggression.
11:26They don't have facial muscles and expressions right,
11:29so that's how they express themselves.
11:31The beak going like this, it was great.
11:33That's a great example of coalition behavior.
11:38Denise has yet to decipher all the subtleties
11:41of these amazing interactions.
11:44Her dream is one day to crack their code
11:47so that she can understand exactly what they're saying.
11:50But how close is she to really talking to dolphins?
11:55I think the technology exists,
11:57and I think our knowledge of the dolphins out here exists
12:01to do that within five years,
12:04to start that process of having a meaningful exchange
12:08with the dolphins.
12:11But communication is only part of being smart.
12:16Intelligent animals are also inquisitive animals,
12:20and there are few animals as inquisitive as dolphins.
12:30West of the Bahamas, off the Caribbean island of Roatan,
12:34the local dolphins are in for a surprise.
12:39DOLPHINS
12:49Professor Stan Kuchai is joined by cameraman Doug,
12:53and he's about to perform a very strange experiment
12:57with one of the most curious species of dolphin,
13:00the bottlenose dolphin.
13:02OK, this is what we're going to do.
13:05This little dolphin is already intrigued,
13:08and the experiment hasn't even begun.
13:25Stan's machine blows bubble rings,
13:28something these dolphins won't ever have seen before.
13:33BUBBLE RINGS
13:48What will the dolphins make of these bubble rings?
13:53Initially, like most dolphins,
13:55they're not very good at swimming.
13:58But as they get older, they learn how to swim,
14:01and they become more and more like dolphins.
14:04In fact, they're starting to learn how to swim.
14:07They're learning how to swim in the water,
14:10and they're learning how to swim in the water.
14:13They're learning how to swim in the water.
14:16They're learning how to swim in the water.
14:20Initially, like most animals, they're a bit wary,
14:24but then curiosity gets the better of them.
14:31One individual seems particularly spellbound.
14:41She's checking out the bubbles not just with her eyes,
14:45but also with clicks of sonar.
14:50And then she braves the bubble ring.
15:10This courageous explorer has paved the way for the others.
15:20BUBBLE RINGS
15:27Just like human toddlers,
15:29it doesn't take long for these imaginative creatures
15:32to make a game out of their new toy.
15:36BUBBLE RINGS
15:48Even after hours with the bubble rings,
15:51the dolphins are still experimenting.
15:56And each has got their own version of the game.
16:01One dolphin prefers a tail flick.
16:10Another, a fin flick.
16:14And the real show-off goes for the swim-through.
16:21While some animals will show initial interest in novel objects,
16:25very few will maintain this level of curiosity
16:28and playfulness for so long.
16:38Wow.
16:39That was amazing.
16:41I was going to say, what did you make out?
16:43That was amazing.
16:44There's a lot going on.
16:46Lots of inventive play.
16:48Lots of inventive play, lots of curiosity,
16:51lots of flexibility in their behaviour.
16:53The dolphins are not just doing the same thing over and over again.
16:56They're trying different things with the bubbles.
16:58So I think what we're seeing is that combination of curiosity
17:01and the ability to change your behaviour,
17:03which I think is one of the hallmarks of dolphin intelligence.
17:07This inquisitive nature and willingness to try new things
17:11enables dolphins to adapt to different situations.
17:15This has huge advantages for their survival in the wild.
17:24BUBBLES
17:30One place to see this is the western coast of Australia.
17:4050km south of Perth, the local dolphins face a tricky challenge.
17:47SEAGRASS
17:51Here, the seabed is coated with seagrass.
17:59While there's plenty of food for dolphins,
18:01the long fronds interfere with their sense of echolocation,
18:05making it difficult for them to detect any hidden prey.
18:10DOLPHINS
18:15But the local dolphins have come up with a clever plan.
18:30Dolphin expert, Sarah Robinson,
18:33has spent many years following these dolphins
18:36and discovered the secret of their success.
18:39Stingrays.
18:43It doesn't take long for her to spot two of the dolphins she's after,
18:47the charmingly named Zit and Pintle.
18:50They're just here.
18:52And they look like they're diving.
18:55I think I've put off the cold water long enough,
18:58so I'm going to have to get in and check out
19:00if they are following the stingray.
19:02Fingers crossed.
19:04Yeah, they are, and I'm not going in for nothing.
19:07Just there you go. Yeah, I'm in neutral. Go for it. Go, go, go.
19:14They're on a stingray!
19:29Sarah free dives to the grassy seabed
19:32and catches a rare glimpse of this strange association.
19:36ZIT
19:59Armed with a lethal barb on the end of their tails,
20:02these stingrays pose a threat to both humans and dolphins.
20:18Zit and Pintle are taking quite a risk,
20:21but they don't seem to be put off as they shadow the rays every move.
20:32Zit
20:50The ray seems to have found something.
20:53Undulating its wing-like fins, it's trying to flush out hidden prey.
21:03Zit
21:09An octopus, a real delicacy for both stingray and dolphin.
21:19Stingrays have an ability that dolphins lack.
21:23They can locate prey hidden beneath the seagrass
21:26using the electroreceptors on the underside of their bodies.
21:33And the dolphins have worked this out.
21:43She got it! She got an octopus!
21:46The dolphins have solved the problem
21:49of how to find their favourite food in the long seagrass.
21:53They're harnessing an ability of another species for their own ends.
21:58The stingrays have done all the hard work,
22:01only to be outsmarted by the dolphins.
22:19On the other side of the world, off the southern coast of Florida,
22:23another group of bottlenose dolphins face a very different challenge.
22:31In the shallows of Florida Bay, the fish can be very difficult to catch.
22:41With the tide receding, this female moves into position,
22:45downstream of the fish.
22:54And then she does something remarkable.
23:05Beating her tail, she stirs up the silt.
23:09She's got it!
23:19She has created a V-shaped wall of mud.
23:23A fish trap. Caught in the jaws of the trap,
23:27the fish have nowhere to go.
23:31Except up.
23:40This ingenious hunting strategy
23:43has been passed down successive generations.
23:47And this female is teaching it to her own youngster.
24:10Just how these dolphins first came up with this extraordinary strategy
24:15is a mystery.
24:17But their use of mud to catch fish
24:20clearly demonstrates their unique powers of creativity.
24:40Perhaps it's this creative intelligence
24:43that draws us to these magical creatures.
24:53Certainly dolphins' curiosity and playfulness captivate us.
24:59But what of their larger cousins, the great whales?
25:10They have the largest brains of all.
25:13So what about their intelligence?
25:16Are they super-smart too?
25:26These humpback whales are on a marathon journey.
25:30They've been swimming for the last 100 years,
25:33and they're not afraid of water.
25:36They're on a marathon journey.
25:39They've been swimming for the last three months.
25:48And their destination is the west coast of Alaska.
26:00The summer sun has fuelled an explosion of life in these deep fjords.
26:07Plankton blooms have given rise to huge shoals of herring.
26:17And this fish bonanza is why the humpback whales
26:21have travelled over 5,000 kilometres.
26:29But feasting on these fish isn't straightforward.
26:33The herring choose to gather in the depths of the fjords,
26:36where it's easier to escape from predators.
26:46For the whales to catch them,
26:49they'll need an ingenious hunting strategy.
27:04DUCKS
27:16Scientist Fred Sharp knows of a particularly smart group of humpback whales
27:21that have a clever solution to catching herring.
27:25And he's invited Doug along to help him record key players in the group.
27:33So how does Fred rate their chances of finding them?
27:37100%.
27:39100%? That's great.
27:41This is their home. We've just got to find where the party is.
27:44It's like a nightclub, you know, finding out where the hot spot is.
27:48Two weeks ago, it was right here. Right now, it's hard to say.
27:51But we'll find them. We'll find them.
28:04Fred has names for over 1,000 whales that come here,
28:09but only 50 are part of what he calls the A Team,
28:13a super-smart group of whales that work together in an extraordinary way.
28:21The unique shapes and marks of each whale's tail fluke
28:25allow Fred to tell who's who.
28:27There's one. Look at that.
28:29There he goes. Show us who you are, baby. Let's see him.
28:33Got it. Hey, it's samurai.
28:36Does it look like a mandarin with the sword marching along?
28:40It does slightly.
28:42Unfortunately, though, he's not one of our core community of whales
28:45that we're looking for.
28:47He's just kind of a lone samurai doing his thing.
28:50And it's a good sign. It shows there's feed in the area.
28:53Fred has known samurai for the last eight years.
28:56He's one of the older humpbacks, but not one of the smartest.
29:02Fred and Doug come across more whales.
29:07Some single, some travelling in pairs,
29:10but still, no sign of the A Team.
29:16Day after day, the search continues.
29:22Just put it on the ground in front of their head.
29:27MUSIC PLAYS
29:43At last, they come across a group that's fast asleep.
29:48It's just like a log floating on the surface.
29:50Without any tail flukes visible, it's very hard to identify individuals.
29:55Yeah, it seems like these animals can teach us a lot.
30:00Cooperation, majesty.
30:03But the one thing they really teach you is patience.
30:06You can see that.
30:09He's up for something now.
30:11He's going to fluke me.
30:13It's Vulture. That's one of the leaders, Vulture.
30:16That's Vulture. Sweet.
30:18Sweet indeed.
30:20They've found Vulture, one of the ringleaders of the A Team.
30:26It's a peach.
30:28That's one of the most awesome things you can see anywhere.
30:31Isn't it? A full breach.
30:33Phenomenal.
30:34You know, it's funny, everybody's had a nice long nap
30:37and it seems like they're starting to wake up.
30:40And it's like sometimes certain whales are like,
30:42let's get it going on, people, let's get it going on.
30:44Let's get your peck flippers in the air.
30:47Yeah.
30:50They've found the A Team, and they're certainly waking up.
31:06No one really knows why humpbacks make such a big deal out of it.
31:11It's just a way for them to show off.
31:14It's a way for them to show off.
31:16No one really knows why humpbacks make these fin slaps and spectacular breaches.
31:22Perhaps the herring have been spotted, and this is the team's call to action.
31:47The A Team
32:05Fred and Doug track the whales as they move to the shoreline.
32:09According to Fred, this is a favourite hunting spot.
32:13Once again they seem to be having difficulty finding the prey.
32:19This is awesome to see these whales here.
32:22This is the core community, these are the leaders,
32:25these are the main bubblers and vocalisers.
32:27This is a very good sign.
32:34They're like apparitions, you know.
32:36It's all magic.
32:39Now they're listening out for the distinctive herding call
32:43and looking for a tell-tale circle of bubbles.
32:49We've been listening to these beautiful mournful calls for 15 years now,
32:54and we've been able...
32:55Oh, I hear it, I hear it!
32:57Right here, right here, to the left, quick!
33:08The A Team
33:27That's just...
33:28Yeah, it's like...
33:29That's really peachy.
33:30The biology is cool, but the beauty just blows me away.
33:32It's lovely.
33:34At last, the A Team are starting to feed.
33:45We're just so close and they're obviously laid back.
33:47It's taken us a while to find the crew, you know.
33:49There were times I was a disbeliever, Fred,
33:51but you've come up with it.
33:53That's really lovely.
33:55The A Team's strategy for herding herring from the depths
34:00relies on a highly coordinated attack
34:02in which each whale has a crucial role to play.
34:10Using sightings like these,
34:12as well as recordings from hydrophones and sonar equipment,
34:16Fred and his team have built up a detailed picture
34:19of what's going on beneath the surface.
34:30Following the ringleader, the whales dive down together
34:34and each one moves into position.
34:40There are the herders.
34:42They circle the fish with flashing fins,
34:45keeping the shoal contained and preventing its escape.
34:53Then there is the caller,
34:55the team who dives below the shoal and emits a deafening cry.
35:04As loud as a rocket launch,
35:06180 decibels of sound pressure blasts through the water.
35:13In an attempt to escape from the noise,
35:15the panic-stricken fish are driven upwards.
35:20This is where the ringleader comes in.
35:25Taking up position above the herring,
35:28it begins blowing out a stream of air
35:31to create a fizzing net of bubbles.
35:38The shoal is prevented from dispersing by the herders
35:42and driven up by the caller right into the bubble net.
35:56Then all the whales gather underneath the fish trapped in the net.
36:08With mouths wide open,
36:10the A team burst through the surface, engulfing their prey.
36:22By hunting together like this,
36:24each whale can catch up to 500 kilograms of herring a day.
36:44Surprisingly, Fred has discovered that none of the A team is related.
36:49Like us, humpback whales can form friendships that last for many years.
36:56THE TEAMWORK
37:15This spectacular display of teamwork
37:18is perhaps the ultimate demonstration of coordination and cooperation
37:24in the whale and dolphin world.
37:44But are whales and dolphins capable of even higher thought processes
37:50that only a tiny elite of life on Earth can lay claim to?
37:57Are they capable of self-awareness,
38:00what one might call existential thought?
38:10At Baltimore Aquarium,
38:12some very special bottlenose dolphins
38:15are participating in one of the world's leading studies
38:18into what dolphins might think about themselves.
38:24Professor Diana Rees has spent over 25 years
38:28studying dolphins' cognitive abilities,
38:30that is, how they make sense of the world.
38:35And she's witnessed some astonishing behaviour.
38:39Recently, we did studies where we actually gave dolphins...
38:42See, they're actually interested in looking at...
38:45And her precision instrument to unlock the dolphins' inner secrets,
38:49a mirror.
38:51So we have... OK.
38:53And... Literally, yes.
38:55So what we do is we give them the mirror.
38:58These dolphins have never seen a mirror in their lives.
39:02How will they react?
39:04And here it comes.
39:10Some other dolphins coming up as well right now.
39:15True to form, they're instantly intrigued.
39:18So what they first do is they explore the mirror.
39:20They try to look behind it,
39:22they try to figure out what this new thing is.
39:27They also look and show behaviour
39:29like they're looking at another dolphin.
39:37This behaviour is shared with monkeys and even birds,
39:41but the dolphins do something that sets them apart.
39:46It looks like they're testing the effects of their own behaviour
39:50in front of the mirror,
39:52understanding that there's a relationship
39:54between what they're doing and what they see in the mirror.
39:57They understand that that's themselves.
39:59This next step requires a giant mental leap
40:03of which very few animals are capable.
40:08It's great. I can watch this all day.
40:10I know. You have to be my research assistant.
40:12It's just great.
40:14This is why I do it. It's fascinating.
40:18There's something even more fascinating
40:20that happens when the dolphins are left with a mirror for longer.
40:24It's subtle, but the implications are profound.
40:28And to see it, we need to go into the ominously named pit.
40:35That's very cosy down here.
40:39Here, Diana puts up a two-way mirror,
40:42while the dolphins just see a reflection of themselves,
40:45Doug can remain hidden from view, recording their reactions.
40:55These dolphins have been staring into the looking glass
40:58for over a year
41:00and just can't get enough of their own reflections.
41:03This is a foster. Foster, yeah.
41:05He's three. He's really curious.
41:09Not only have they worked out that the reflection is theirs,
41:13but they seem endlessly absorbed by the image they see.
41:28They're using the mirror as a tool to view themselves,
41:32and it also suggests
41:34that they're interested in what they look like.
41:37That requires a sense of self.
41:39This is a very high level of awareness.
41:45Only humans, great apes and elephants
41:48share this sophisticated level of self-awareness.
41:54But can these apparently narcissistic tendencies
41:58reveal more about the inner workings of their minds?
42:03Human babies only start to recognise themselves in a mirror
42:07at the age of about two years old,
42:10and it's at this age that they also start to show another ability.
42:14Empathy.
42:16The capacity to identify and understand the feelings of others.
42:33Is it possible that whales and dolphins
42:36could mirror the emotional development we see in human babies?
42:43Might they too be able to empathise with others?
43:03Off the eastern coast of Mexico, in Baja, California,
43:08there is one group of whales that behave in a way
43:11that suggests they are capable of feeling for others.
43:18Female grey whales gather each year in these warm, sheltered waters
43:23to give birth and to nurse their calves.
43:27But this whale nursery wasn't always a safe haven.
43:37Only 75 years ago, it was the site of many a massacre.
43:42Whalers could pick off the slow-moving greys with ease.
43:47The whales fought back.
43:50Their attacks were so ferocious
43:53that they became known as hard-headed devil fish.
44:02Even after hunting was banned,
44:04whales and humans remained wary of each other.
44:12Then, something extraordinary happened.
44:16In 1972, a local fisherman, Pachico Majorao,
44:21had an encounter he would never forget.
44:29On that fortunate day, I wasn't looking for whales.
44:32I was fishing.
44:34But then, unexpectedly, a whale came up alongside my boat
44:38and started to swim towards me.
44:41Then, unexpectedly, a whale came up alongside my boat
44:45and started poking its head out of the water.
44:48I was afraid.
44:52Expecting the boat to be wrecked by the devil fish,
44:56Pachico was amazed when the whale gently nudged alongside his tiny boat
45:02and looked into his eyes.
45:05Overcoming his fear, Pachico reached out and stroked the whale.
45:16After the initial excitement, I calmed down.
45:20Then I realized that the whales, despite how powerful they are,
45:24can live alongside us humans.
45:29I think that the whales are not resentful
45:32and that they want to share their space with us.
45:36They are very intelligent, perhaps even comparable to us,
45:40because they have shown us feelings, forgiveness.
45:46In that one instant, Pachico's attitude towards whales was changed forever.
45:57I feel that despite their size, they have a heart to receive us,
46:01a heart that's even bigger than they are.
46:09Today, people from around the world come here to meet the friendlies.
46:31That is a rain blow.
46:38Marine biologist Tony Frohoff has been studying the interactions
46:42between humans and whales here for 15 years.
46:47Nowhere else in the world, really, do you see this type of thing.
46:51It's completely unique in where the whales come right up to you
46:55and they're doing it on their terms.
46:58They're living their lives here, nursing their young, giving birth, mating,
47:02but yet they still come up and they interact with boats like this.
47:06And there must be something that they're gaining emotionally, psychologically,
47:11from this type of interaction with people.
47:13And in the process, they're bringing out some of the best in people.
47:18Well, the whale just came right up and there was nothing else to do
47:22but give him a kiss.
47:25I managed to kiss the baby about three times
47:29and I thought life couldn't get better than that
47:32until the mum came up right between my arms and I got to hug her.
47:47Some of the older grey whales who would remember the days of whaling
47:51are still here today.
47:55So what has brought about this astonishing change in their behaviour towards us?
48:04Not only have these ocean giants lost their fear of us,
48:08but they appear to be seeking us out and actively enjoying our company too.
48:17Emotional awareness is generally regarded as one of the highest forms of intelligence,
48:23but awareness of emotions in another species is even more impressive.
48:29That's amazing. Amazing.
48:35The latest research on whale and dolphins' brains
48:39has revealed something quite unexpected.
48:44Like us, they have spindle cells.
48:47These special brain cells were once thought to be unique to humans
48:51because of their link with language, self-awareness and compassion.
49:01Yet some whales and dolphins may have three times as many spindle cells as we do.
49:10What I'm observing defies a lot of what we have been taught
49:16and we are now having to teach that there is more literally beneath the surface
49:21of these whales than meets the eye.
49:46WHALE AND DOLPHINS
49:52Through the world's leading scientists,
49:54we are learning so much about the remarkable intelligence of whales and dolphins.
50:04But there is something that science cannot yet explain.
50:09Our extraordinary connection with these magical creatures.
50:18They really invite you in their family.
50:21You can get right in there, you can share their moments, their intimate moments.
50:31You realise just how complicated the societies that these animals live in.
50:37But you also have to ask yourself, are these animals trying to talk to us?
50:46When you really look into the eye of a dolphin or a whale,
50:50you see something behind them.
50:52You see that they're sentient, they're assessing you, they're aware, they're self-conscious.
50:57Perhaps one day soon, we may learn to communicate with these mysterious creatures.
51:06And then maybe they will tell us themselves
51:09what is really going on in the minds of the ocean giants.
