00:00NEPTUNE CONTROL
00:03Go ahead, control
00:05Summer 2024
00:08NEPTUNE, you are all stopped
00:11If you choose, move up low
00:14to 180
00:16and follow transects to the north
00:19Roger
00:21An expedition is setting off
00:26in search of a little-known fish
00:27that lives in the deep sea
00:30Its proselys skeletons
00:40had been found in rocks
00:42that are 400 million years old
00:44and suggest that these fish
00:47could be the ancestors
00:48of all backboned animals
00:50including ourselves
00:52But their fossils disappear
01:00at the same time as those of the dinosaurs
01:0266 million years ago
01:05Then in 1938
01:09a trawler
01:10fishing off the coast of South Africa
01:12made an astonishing catch
01:14It was undoubtedly the same kind of fish
01:19as coelacanth
01:20but an hour or so earlier
01:22it had been alive
01:24It was a sensation
01:25a true living fossil
01:27But little was known
01:31about how and where it lived
01:34Now, a special expedition
01:37in a state-of-the-art research ship
01:39is setting off to try and discover more
01:42about this living fossil
01:43Ready for the water
01:45And they hit lucky
01:50There was a whole group of these ancient fish
02:03Oh, but look
02:08Look how they're all moving
02:10It's so crazy
02:11And look at the white tummy
02:14They even witnessed
02:17for the first time
02:19what appears to be
02:20its mating behavior
02:22And the video recordings they made
02:28shed light on how primitive fish
02:29like the coelacanth
02:31may have used their fins
02:32to walk on land
02:34It's just gorgeous
02:37And when we look at creatures like this
02:39we see the evolutionary history
02:41we share with fish
02:42Join us
02:46on a journey
02:47to discover more
02:49about this mysterious survivor
02:51from the very ancient past
02:53The island of Sulawesi
03:09in Indonesia
03:10It straddles the equator
03:16And the waters around it
03:22contain some of the richest coral reefs
03:25in the world
03:26This is Ocean Explorer
03:34A vessel specially equipped
03:37for deep sea research
03:39The team has special permission
03:42from the Indonesian government
03:43to spend two weeks
03:45looking for living coelacanths
03:48The coelacanth is called
03:52Raja Laut in Indonesia
03:54which means
03:55King of the Sea
03:56They have a pair of powerful deep sea submersibles
04:03Each has a transparent dome
04:07that will give it almost 360 degree visibility
04:11And they are fitted with an 8K deep ocean camera system
04:20specially developed for this trip
04:22The ultra sensitive cameras
04:26are able to record clear pictures
04:28even in the darkest depths
04:30They will also use a large unmanned ROV
04:36a remotely operated vehicle
04:38This ROV is equipped with additional cameras
04:46and can film in all directions
04:49These are the lead scientists on the expedition
05:05Dr. Masamitsu Iwata
05:10has been carrying out research
05:12on coelacanths
05:13for over 20 years
05:15It's a big one
05:18It's a little compact
05:21Having worked and dived
05:24in the Indonesian waters
05:25for over 20 years
05:27Iwata knows these seas very well
05:30Wow
05:33I'm Kerry
05:35Lovely to be here
05:36I'm from South Africa
05:37Good girl
05:38Pretty good
05:39Dr. Kerry Sink
05:41first became fascinated by coelacanths
05:44when she was a child
05:49To really see the seascape
05:51and the terrain
05:52is going to be an incredible experience
05:55and I think what would be amazing
05:57is to see a coelacanth
05:59Abel to Abel
06:04The team are planning
06:06to explore the waters
06:07off the northern shores of Sulawesi
06:13The area is renowned for its active volcanoes
06:16and frequent eruptions
06:18have created numerous caves
06:20and cavities on the sea floor
06:24An earlier survey
06:26found a steep underwater cliff here
06:28which the team are keen to investigate further
06:36As the sun rises
06:37they're ready for their first dive
06:43Both subs will be used
06:45so they can cover as much ground as possible
06:48and they're not feeling
06:49and the water
06:50and they're not feeling
06:52but I'm going to see the sun
06:53now
06:54as they're ready for the break
06:56I'm hopping to the sun
06:57and I'm sitting at the sun
06:58and stepping up
06:59and the air
07:00and stepping up
07:01and there's this one
07:02yeah
07:03I'm going to go
07:04And I'm going to go
07:05and I'm going to go
07:06and and I'm going to go
07:07¡Suscríbete al canal!
07:37Then, they launch the Saturn Submersible, Nadir, with Kerry on board.
07:52So, Neptune's ready now.
07:55Roger, we'll stop spending now. Have a good day.
08:07Star Wars
08:08The Saturn Submersible
08:16Time
08:19Time
08:20The Saturn Submersible
08:23Death
08:251, 0, 0 meters
08:27Leaving the creatures of the shallows behind, they head for deeper water.
08:34They're now at a depth of 200 metres.
08:39Deeper than this, it's pitch black.
08:44Control, control, this is Neptune.
08:46Depth 2 to 4 metres.
08:50Arm up.
08:50They now plan to search an area roughly half a kilometre long.
09:01But in this darkness, that is not an easy thing to do.
09:08I'm moving on the wall, and I'm looking at the light of the light.
09:15If you look at the light of the light, you'll be able to find the light of the light.
09:19So, I'm looking at the light of the light of the light.
09:21So, I'm looking at the light of the light.
09:22I'm looking at the light of the light.
09:23I'm looking at the light of the light.
09:26They're searching for bright spots that could be reflections from a silakanth's eyes.
09:40There are two bright specks in the darkness.
09:49It's a carpet shark, sitting motionless on the sea floor, waiting for prey.
10:07Meanwhile, Kerry's sub is scouring a different section of the cliff face.
10:11Underfish.
10:18Underfish.
10:19What is it?
10:20Jelly nose.
10:21Jelly noses.
10:22The crazy ones.
10:26It's a jelly nose.
10:28A rare kind of deep sea fish that, until recently, had never been seen alive.
10:33Its long ray-like fins are thought to be sensors that allow the fish to feel its way around in the darkness.
10:46I've never seen one before.
10:59I've never seen one before.
11:00I've never seen one before.
11:07Thresher shark, Clark.
11:09Oh, oh, oh, oh, shark.
11:11Dark.
11:12Yeah, thresher.
11:15It's a thresher shark, with a distinctive long tail fin.
11:19It's at least three meters long.
11:21I'll slowly come up towards him.
11:22I'll just see how he reacts, okay?
11:23Yeah.
11:24Yeah.
11:25Yeah.
11:26They appear to have entered the shark's territory.
11:27And it's slowly circling the submersible.
11:28Oh, no.
11:29Oh, no.
11:30Oh, no.
11:31Oh, no.
11:32Oh, no.
11:33Oh, no.
11:34Oh, no.
11:35Oh, no.
11:36Oh, no.
11:37Oh, no.
11:38Oh, no.
11:39Oh, no.
11:40Oh, no.
11:41Oh, no.
11:42Oh, no.
11:43Oh, no.
11:44Oh, no.
11:45Oh, no.
11:46Oh, no.
11:47Oh, no.
11:48Oh, no.
11:49Oh, no.
11:50Oh, no.
11:55Two smaller fish have sought shelter underneath the sub.
12:04They don't seem in the least fazed by such a strange contraption
12:08and appear to be using it as a place to hide from the shark.
12:12disobedient.
12:13Itάpm f extraction.
12:14It advests funcion chks away.
12:19Oh.
12:20But suddenly, there's a problem.
12:25See, it's different.
12:26See, it's shimmering.
12:27Oh, usar...
12:29La corriente de agua ha encendido el suelo de la tierra y las partículas de sedimentos están oscuros.
12:41No es más seguro de continuar.
12:44Las que regresen a la superficie.
12:46El área es conocida por sus fuertes y impregnables océanos
13:03que pueden hacer la exploración de la underwatera muy peligrosa.
13:07El equipo tiene que ser preparado para setbacks como esta
13:10pero es frustrante cuando su tiempo aquí está tan limitado.
13:16So, ¿por qué son los científicos tan fascinados por la coelacanth?
13:33Se parece que estos primitivos animales pueden resolver un largo plazo de la evolución.
13:39La coelacanthas se aparecen más de 400 millones de años antes de los dinosaurios.
13:49Y ellos han vivido en los océanos alrededor del mundo.
13:52Es pensado, que se han convertido a la coelacanthas a la misma vez que los dinosaurios,
13:5866 millones de años antes.
14:01Entonces, en 1938, la coelacanthas pulled up from the depths of the Indian Ocean
14:15a specimen of this ancient fish that was alive.
14:21Its discovery stunned the scientific world.
14:24The coelacanthas was not extinct after all.
14:31Then, in the 1950s, another specimen was caught off the coast of Africa
14:37and I had the privilege of examining it.
14:39Its fins have long fleshy lobes at their base
14:43which make them quite unlike the fins of any other living fish.
14:48In fact, the fins were so muscular
14:52that it was thought it might use them like simple legs
14:55in order to walk across the sea floor.
15:00Since those first discoveries, scientists around the world
15:04have been searching the deep sea for a living coelacanth.
15:08Then, in 1997, there was another surprising discovery.
15:15A coelacanth was caught far from Africa in Asian waters.
15:22The discovery reawoke interest in this strange fish.
15:27Three days into the expedition,
15:41and the team have decided to try a new strategy.
15:46Find those points.
15:48They have decided to concentrate their search
15:59to depths of around 160 metres,
16:03which are rich in underwater caves
16:05and where water currents are relatively stable.
16:08Today is the day we're going to find the fish.
16:26Fifty minutes into the search,
16:28and Iwata notices some interesting-looking rocks.
16:32Clumps of them stand on the otherwise even sea floor.
16:51The sub approaches cautiously.
16:54The cameraman has noticed something
16:59between the two clumps of rock.
17:05Oh, there's something there.
17:06It's a silokanth.
17:07What's that?
17:09Oh, that's silokanth?
17:11Is it silokanth?
17:12Yeah, maybe.
17:13Maybe.
17:16A closer look reveals a creature
17:18hiding in the cracks.
17:20What's that?
17:24Is that silokanth?
17:25Oh, yeah!
17:26Yeah, yeah!
17:27We found silokanth!
17:28We found silokanth!
17:31The team are thrilled.
17:33It's their first glimpse
17:34of a live silokanth.
17:36Unlike the dead specimens,
17:38the living silokanth
17:40is a steely blue colour
17:41with light flecks.
17:47I can get us a little closer,
17:48Pero si hacemos un poco de filmación aquí, así que no nos dañamos a hacer esto, ¿verdad?
17:53Sí, sí.
17:57¿Y ha sido silicón?
17:58¿Usted ha sido silicón?
17:58¿Usted ha sido silicón?
18:00¿Has sido silicón?
18:01Sí.
18:02¿Están ahí?
18:03Sí.
18:04Control, control, esto es neptune confirmación.
18:07¿Has sido silicón?
18:08¿Has sido silicón?
18:09¿Has sido silicón?
18:10¿Has sido silicón?
18:11Se ha venido con un ch necesito
18:14After half an hour, the silicón
18:18Emerges, giving them a better view.
18:20Es por más de un metro NEGAL!

20:56Perhaps it acts as a small rudder and helps the fish to make tight turns.
21:04Or maybe it's an alecto-sensor that helps it navigate in the eternal darkness.
21:10Much about this ancient creature is still a mystery.

21:43¿Cómo el coelocant survives a great depths
21:46still remains largely unknown
21:48despite efforts of scientists
21:50across the world?
21:52Deep sea exploration is not only challenging
21:56but costly
21:58so every day is precious
22:02To maximise their chances of observing more behaviour
22:06the team have decided to deploy
22:08all of their equipment simultaneously
22:12We are launching
22:14number 2
22:16before we are recovering number 1
22:18Yes, that was the request
22:20All this and all that
22:22Yes
22:23Okay
22:24Okay
22:25Thank you
22:28The aim is to carry out
22:30continuous observations
22:32for 72 hours
22:36It's an ambitious plan
22:38and requires the crew
22:39to run the subs in shifts
22:41day and night
22:45This is a first
22:46even for the crew of Ocean Explorer
22:49The scientists are now sure
22:54that coelocants stay dormant
22:56throughout the day
22:58They suspect that the fish is nocturnal
23:02so they start their daily shift
23:04in the early evening
23:12Control, control, control, this is Neptune
23:15and I have given sight
23:16This coelocanth
23:20is still in exactly the same spot
23:23as it was when they found it
23:25the previous day
23:30But the team must be ready to respond
23:32if and when it does move
23:34It does move
23:39They know perfectly well
23:40that the coelocanth
23:41to sustain its massive body
23:43must come out to feed sometime
23:49But it doesn't move
23:51even at night
23:53as the team proves
23:54by speeding up their video recording
23:57It remains in exactly the same spot
24:00At midnight
24:03the second sub with carry-on board
24:05sets off
24:13She now takes over from Iwata
24:15in keeping watch
24:17OK mate
24:18Have a great day
24:19Have a great day
24:32But even after 10 hours
24:34the coelocanth
24:35has still not shifted
24:37and shows no sign
24:39of wanting to look for food
24:41Finally, at 8 in the morning
24:49the team decide
24:50to bring out
24:51the unmanned ROV
24:52Finally, at 8 in the morning
24:53the team decide
24:54to bring out
24:55the unmanned ROV
25:01Kerry is exhausted
25:04They've now been watching
25:06the coelocanth continuously
25:08for 24 hours
25:09but it still has shown
25:12no sign of moving
25:17Perhaps the sub's lights
25:18are making it nervous
25:23So they switch
25:24to infrared lights
25:26that are virtually undetectable
25:27by any fish
25:30OK, darkness
25:31Darkness
25:32and still
25:37the coelocanth
25:38does not move
25:48At 7am
25:49the following day
25:5039 hours later
25:52it finally does something
25:54The coelocanth
25:55The coelocanth
26:08at last
26:09is on the move
26:10We're supposed to follow there
26:11Yeah
26:12Do we follow?
26:13Yeah
26:14Do we follow?
26:15Yeah
26:16Well, of course not
26:17It swims slowly
26:24but in a way
26:25that our scientists
26:26have not seen before
26:28It propels itself forward
26:42by moving its fins
26:43rhythmically
26:44from left to right
26:49The two fins
26:50appear to provide
26:51forward propulsion
26:52The head is a vertical cliff face
27:12It's really interesting to see if she goes up
27:24There's a crack here
27:25at all
27:29Ah, she's going along the crack
27:33The coelocanth
27:34makes its way purposefully
27:36along the steep cliff
27:42So this is a good
27:45Then
27:46it comes
27:47to an overhang
27:48in the rocks
28:07She's near?
28:08Yeah
28:09That's perfect
28:10What?
28:11Yeah
28:12We want to leave her somewhere
28:13where she can maybe stay
28:14We don't want her going
28:15We don't want her going
28:17Mark

28:27The fish
28:29has disappeared
28:30into the crevice
28:37Oh
28:38Oh
28:39Oh
28:41Jim
28:42The place where the coelocanthus
28:44chosen to hide
28:46is one
28:47the scientists
28:48had not expected
28:49It's a large overhang in the cliff
28:52effectively
28:53an underwater cave
28:55Tracking the fish's movements
28:59has led them to a new hideout
29:01This is a real reward
29:04for their 72-hour vigil
29:07Vigil
29:14Then Terry spots something else
29:17Oh, I think I see another one
29:19What?
29:20On the left
29:25Oh, sorry
29:26There
29:27There you go
29:28Is it?
29:35There appear to be more coelocanths
29:37hiding in the cave
29:39It's an extraordinary sight
29:41One
29:42Two
29:43Three
29:44Four
29:45Five
29:46Six
29:47Seven
29:48Eight
29:49Eight
29:50Eight
29:51Eight
29:52Eight
29:53What is happening?
29:54There are definitely eight individuals
29:59and the team are astounded
30:01What could be the reason for such a gathering?
30:04This morning aggregation
30:15It's hard to know why these coelocanths have assembled in such a tight space
30:21but they seem to be resting peacefully side by side
30:36Suddenly the thresher shark reappears
30:40The coelocanths retreat further into the crevice
30:51The arched overhang provides good cover allowing even a large fish like a coelocanth to hide unnoticed
31:10The cave also provides protection from ocean currents so there is little danger of being swept away
31:28It's a fortress in the kingdom of the coelocanth
31:40To help them get a better view beneath the ledge the crew use another piece of equipment
32:04It's a tiny underwater camera that they manoeuvre into position
32:09and attached to the rock face
32:12Despite its small size, it gives a surprisingly detailed image
32:21They can just distinguish a coelocanth huddling underneath the ledge
32:32Within minutes, swarms of tiny fish appear
32:36They're lantern fish attracted by the camera's bright light
32:39They're lantern fish attracted by the camera's bright light
32:51Once the swarm has dissipated, the coelocanth comes into view again
32:56And then...
33:03Slowed down, we can see what happened
33:08Faster than the blink of an eye, it lunges for a passing morsel of food
33:14This is very different from the slow-moving languid creature the team had seen until now
33:29The footage clearly shows the coelocanth feeding in a manner only known to be used by prehistoric fish
33:36Until now
33:39Recent research has shown that this way of feeding is only possible because of the unique shape of their skull
33:47It is in fact split into two halves, which are connected by a special hinged joint
33:54This allows the fish to widen its mouth to more than 30 degrees
34:02Enabling it to bite with the force needed to feed on hard, scaly animals
34:08Or to swallow particularly large prey
34:14Many ancient sea creatures once had this kind of a hinged joint
34:18But the coelocanth is the only known living fish to still possess one
34:27So at last, we're starting to unravel some of the mysteries that surround this ancient creature
34:34It uses its fleshy fins to propel itself slowly through the water and into narrow crevices
34:42But when necessary, it can move surprisingly quickly
34:50And the unique joint in its skull allows it to open its mouth wider than most modern-day fish are able to do
35:01These ancient features have clearly served the coelocanth well for millions of years
35:07Recently, scientists have discovered that coelocanths can live to be a hundred years old
35:17In the deep, it seems that it's the slow and the steady that wins the race
35:22The scientific team are keen to take a closer look at the footage to solve a particular puzzle
35:35What?
35:41Oh, beautiful
35:42Yeah
35:50Its fins have a thick, fleshy base
35:54A characteristic feature of an ancient group called the lobe-finned fish
36:02The fins of most modern-day fish are connected to the body in a way that enables them to flap
36:07But little more
36:16The coelocanth's fins, however, are much larger
36:20And have a row of bones attached to thick muscles
36:23Which gives the fins much greater strength
36:26This arrangement is also found in the limbs of most land animals today
36:31And suggests they share a common ancestor
36:35Scientists have long puzzled over how animals first haul themselves out of the water and onto land
36:45The coelocanth may provide the answer
36:48Their fleshy fins may have led to limbs with an upper arm, a forearm, and fingers and toes
37:04And that enabled the first backbone animals to crawl out onto land
37:09Once the evidence from the fossil record is compelling
37:23It can't show us exactly how these ancient creatures moved
37:27At the University of Chicago, evolutionary biologist Dr. Neil Shubin has been trying to solve this puzzle for years
37:39And is very excited by the team's discoveries
37:43It's like it's a fish with arms
37:46That's what's amazing
37:47So the way they swim is with movements of an arm
37:54They're doing this
37:56It's not just a little paddle
37:58It has bones inside that can move much like our own arm bones
38:02Look at that turn around
38:06A closer look at the footage reveals some important details
38:10Of how the coelocanth uses its frontal or pectoral fins
38:14It appears to rotate each fin as if it were trying to stroke its own head
38:30Slowed down, we can see the movement more clearly
38:36By superimposing the bone structure onto the fin
38:39We can see that the bone bends at each joint
38:43Allowing for this wide range of movement
38:46Even the scientists themselves are surprised by this revelation
39:01I haven't seen it like this, no
39:05I can make guesses, hypotheses, about how those bones actually moved
39:11But I don't really have the creature to look at
39:14I'm inferring it from a skeleton
39:17But when I see a video like this
39:20I begin to see a living creature and how those bones are used
39:24So it allows us to interpret those fossils in whole new ways
39:27As we study these fish, we understand something about ourselves
39:34I find that very powerful and very beautiful
39:38And when we look at creatures like this
39:40We see the evolutionary history we share with fish
39:43On land, these bony and flexible structures supporting the body
39:46Would have then gradually evolved into well-mossed legs
39:56Over time, those early limbs evolved into many different forms
40:04Sturdy legs for walking on land
40:07Light wing bones for taking to the sky
40:13And dexterous hands capable of grasping
40:18They evolved to meet the needs of different habitats
40:25And as a result, life on land became rich and varied
40:32The coelacanth's fins led to limbs suited to movement on land
40:37And so paved the way for all terrestrial life
40:41And our own evolutionary history
40:43Once the coelacanth has shed important light on evolutionary questions
40:54We still know very little about how the species lives
40:58Dr. Kerry Sink is hoping to answer some of these questions
41:04One of her main aims is to find out more about the fish's reproductive behaviour
41:09Scenacanths have white speckles all over their bodies
41:16Each fish has its own unique pattern and looks slightly different
41:27Kerry has used these differences to identify individuals
41:32I want to be paying attention to what's happening from fish to fish
41:42So I've been taking careful notes about which fish is which
41:46And how they might be interacting
41:48On this expedition, one particular individual has attracted Kerry's interest
41:54It's the female that she had followed to the group under a ledge
42:00Kerry recognises it by a unique feature
42:06So the W mark is one of the most distinctive marks on the right flank of the big female
42:14Kerry knows it's a female because of its size
42:18Females are larger than males
42:21She's keen to follow this female to see if she can discover any evidence of breeding activity
42:28The sub prepares for another dive
42:35They have headed to the rock face where they last saw the female coelacanth
42:40They have headed to the rock face where they last saw the female coelacanth
42:55I haven't seen the W. Have you seen the W?
42:59After 30 minutes, the female with the W mark appears
43:04She is over a metre long and because she's larger than the others
43:16Kerry has nicknamed her Big Mama
43:20And she continues to keep a close watch on her
43:23Five hours later, the coelacanths begin to do something that the scientists have never seen before
43:35Some of the fish begin to hang vertically in the water
43:43Oh, but look! Look how they're all moving!
43:50So crazy!
43:52Kerry believes that this may be coelacanth courtship behaviour
44:00I think we have melting coelacanths
44:02And look at the white tummy
44:12They don't normally look like that, right?
44:19Very interesting behaviour
44:21The coelacanths have turned their undersides white
44:28Many fish change colour in order to attract a mate
44:33And Kerry suspects that coelacanths may also do so
44:37To appeal to the opposite sex
44:39The team in the other sub are also witnessing some interesting activity
44:55One of the coelacanths is heading away from the rest of the group
45:02It's heading straight for another fish approaching from the other side
45:07What's that?
45:08Oh!
45:10It's amazing!
45:11It's amazing!
45:12It's amazing!
45:13It's amazing!
45:14It's amazing!
45:15It's amazing!
45:16It's amazing!
45:17It's amazing!
45:22The two fish begin to circle each other
45:27Perhaps their rival males competing for a female
45:37Back at Kerry's sub, Big Mama, with her distinctive W mark
45:47Is also being approached by a male
45:52He is clearly smaller than she is
46:00As he sidles up to her, he appears to rub his head on her underside
46:08The researchers think that she might also be producing some kind of a theramone that attracts males
46:23He continues with this curious mating dance for over three minutes
46:28This is the first time that anyone has seen coelacanths interacting with one another
46:46It's an exciting discovery that brings us one step closer to understanding their breeding behaviour
46:52For Kerry, this is a career highlight
47:02Just like deep gratitude and something I've wanted for a long, long time
47:0924 years
47:10I told the coelacanths, thank you
47:13Thank you, thank you, thank you
47:17Big hugs for us!
47:19Congratulations!
47:21Thank you!
47:22It's so cool!
47:23Of course!
47:24Of course!
47:30Although coelacanths have managed to survive for 400 million years
47:34They now face a new threat
47:44Oh, what's this?
47:47Ohhhh!
47:48There is something drifting in the water
47:54Trash, I guess, maybe?
47:56Yeah
47:58The team are shocked to discover plastic waste
48:02Even at these depths
48:07Throughout the expedition, they found evidence of human waste products littering the ocean floor
48:12So many sunbots
48:17Yeah
48:23The ancient fish now face a deep-sea home full of our rubbish
48:30And a dead coelacanth has even been found with plastic bags in its stomach
48:36The coelacanths home is often close to human habitation
48:50Strong storms and typhoons carry rubbish deep into areas where the coelacanths live
48:56Today, our activities threaten the home of this ancient creature in all of the world's oceans
49:19The two-week expedition has come to an end
49:22The coelacanths are very high
49:30The coelacanths are in a very deep place
49:34We live in an entirely different environment
49:37But we have to feel something that we have come to the common roots
49:41We have a lot of feeling that we have to feel
49:44The coelacanths are very close to the same, very close to the same
49:49El coelacanth es realmente un animal muy especial, que tiene esta ventana hacia el pasado, que tiene estas realmente únicas features que inspiran increíble curiosidad.
50:04Para mí, el coelacanth es también el survival ultimo, y yo estaba simplemente experiencing amazamiento, awe y gratitud.
50:14El coelacanth es la vida de la coelacanth es la primera vez.
50:22Sus descubrimientos han ayudado a entender una creación que se ve muy similar a los que vivieron 400 millones de años atrás.
50:34Hidiendo beside underwater clifas, ahora tiene un estilo lento y eficiente de energía.
50:44La coelacanth es la vida de la coelacanth.
50:50Y breathes unobtrusively.
50:52La coelacanth es la vida de la coelacanth.
50:58La coelacanth es la vida de la coelacanth.
51:02Como especie, coelacanth has survived all the environmental upheavals that have transformed the planet.
51:10Watching them has brought to life one of the most crucial episodes in the history of life,
51:18when fish with stout fleshy limbs emerged onto the land for the first time
51:24and became the ancestors of all land living backbone animals, including us.
