In the depths of the sea where the Peters of Parmiville have lived since the earliest times, following reports from local fishermen, the team set out in search of a strange fish said to lurk in these waters.

It is a journey full of surprises and extraordinary encounters. Finally, after a year of exploration, they discover a strange fish that few people have ever seen and encounter some of the

ocean

's most elusive inhabitants. It is the trip of your life. The island of New Guinea in the Pacific Ocean. It is a wild paradise that still remains practically intact. By modern civilization, a scientific research ship is here to explore the unexplored depths of these waters. The illusory is equipped with the latest technology, including a

deep

-sea submersible that can dive to depths of a thousand meters. The crew is carrying out final safety checks on the Nadia submersible.

No one has ever attempted to dive in these waters before. With us up, the expedition is led by marine biologist Mark Earthmen. Earthmen is an expert in the ecology of coral reefs and has studied for more than 20 years. He has worked in these waters for more than a decade and knows them well. His first stop is the Raja Ampat Islands off the western tip of New Guinea. Well, let's say that the warm waters are already full of colorful fish. Nowhere in all the world's seas is there a greater diversity of life, more than 500 species. Many corals live here, they in turn support a large number of fish that depend on them for food and protection.

Tropical waters are surprisingly rich in nutrients, but the coals produce enough food to support a vast community of sea creatures. Edwin has identified more than 1,500 species of fish in The shallow waters here confirm that this is one of the greatest biodiversity hotspots in the world, but Edmond has long wanted to explore the deeper

ocean

. It all started with an extraordinary discovery he made more than 15 years ago while traveling on the island of Sulawesi. in Indonesia, so it was on my honeymoon in 1997, we were in Minato and we were diving there and I always liked going to the fish markets just to see what people catch there, so we went pretty early in the Tomorrow my wife saw it for the first time, very intrigued by what it was, it was something she had never seen before, so she called me and asked me what it was.

Edmund immediately recognized the strange looking fish and I said, oh my God, it's silica, the coelacanth. It is a very rare fish that was once thought to be the ancestor of all living bottom animals. It has armor-like scales, large, bulging eyes, and fleshy fins that resemble limbs. I was very surprised to see that it's something I knew about as a child, but obviously. I had never seen a real one so it was fantastic and a big surprise to see until our first members were captured off the coast of South Africa in 1938. The coelacanth was thought to be extinct.

It had only been known from fossils of more than 80 million. years and the discovery of a live specimen caused a scientific sensation: it measured more than one and a half meters and weighed almost 60 kilos. The news of the strange fish Pramila soon spread around the world. 50 years later, Birdman himself found another coelacanth in Asia, far from Africa, it was a different species and once again the strange fish captured our imagination. A few more specimens have since been recovered in Indonesian waters, but only in a handful of places. The earthling believes that its distribution area may be much wider than we think.

For a long time he dreamed of carrying out a large-scale exploration of the depths of the Pacific Ocean. Other prehistoric creatures, such as deep-sea and motor sharks, have already been discovered here, and he hopes to one day find the coelacanth. There is an important question about why we have Many of you here, what about the deep tropical sea and maybe really trying to uncover some of the mysteries of the ancient deep tropical seas? The expedition that the administrator and his colleagues are planning will require a lot of preparation and will take more than a year from the inside out.

The submersible The team will have a nearly 360-degree unobstructed view around it The submarine is also equipped with a high-resolution camera that can capture even subtle shades of color underwater With final preparations complete The submarine is ready for its descent I think there is a very good chance that coelacanths will be found right here, we are in the right place and I am very excited about this and yes, ready to go Edmund is excited and nervous, the submarine is carrying almost 8 tons, a Furby lowered into the sea by a huge crane are the admirals first in the depths beneath the coral reef that surface is really I have clear to ventilate the submarine slowly descends into the depths the further down they go the darker it becomes very little light penetrates these gloomy depths I have a complete fanox of small tiny squid one I'm kind of fine the seabed is very different from the coral reef that is above bare and arid there are few signs of life here at last they see something the strange heart-shaped creature at the end of the stem is a strange jelly in comb-like shape that was first discovered in 1941 by the Japanese emperor Hirohito, who was also a passionate marine biologist, this gelatinous creature lives attached to a rock at the bottom of the sea and feeds in the most extraordinary way: it sheds long sticky filaments that They catch small prey that drifts by. in the water the sun has dropped below 200 meters and is entering what is known as the twilight zone very little light penetrates in degrees this that sea urchin the sea urchin looks quite different from most Modern virgins in fact have fewer spines.

They look more like fossils from 200 million years ago and belong to a primitive group known as pencil stocks. Due to the thickness of its spines, the team noticed another unusual creature at the bottom of the sea. This is true. What is not fossils can be found here. I watch that video and I think it's bad, so these are sea lilies that are not static, exactly as they look in the fossil record. The sea lily resembles founder fossils dating back 400 million years. It has changed very little over the millennia. perhaps sensing the presence of the sun as it approaches the sea Lily begins to wave its arms.

It may look like a plant but it is actually an animal and if it is in danger it will resort to a remarkable strategy: it separates itself and uses its feathery arms to crawl. On the seabed in search of a safer place, the seed lily may have retained its primitive form for millions of years, but it is not long enough to have survived into the modern era. Discovering these living fossils has been quite overwhelming for administrators. They were once much more abundant than they are today and were then found mainly in shallow waters 400 million years ago thick carpets of these strange creatures covered the sea floor forming spectacular underwater meadows the warm shallow waters were rich in plankton and There were few large predators, the Nortonis, an ancient relative of the squid, the octopus hunted small marine invertebrates such as trilobites.

Over time, more formidable predators began to appear, primitive sharks and huge armored fish with powerful jaws with the ability to swim quickly. These formidable hunters dominated the shallow seas while many prehistoric creatures became extinct. Sea livers and some other species survived as living fossils in the twilight zone. The key to his success was his ability to adapt. During the era of dinosaurs, even larger and ferocious predators appeared in the shallow seas. Large swimming reptiles like PCs or now slow ones. -animals that moved without weapons were easy prey those that lived in deep waters were largely unaffected by this survival bubble there are descendants of the living fossils that we know today the coelacanth and the seed that is here in the depths there was few competitors and it was too dark for most predators to find them the submarine returned to the surface the first dive was completed thank you sir have a fantastic trip I would say it really was otherworldly it was truly a

lost

world we found, I think if we had more time here we would definitely find it, since the cancer, the team stopped coming for the next phase of the expedition.

Edmund decides that the focus has been on finding prehistoric fish, including the coelacanth, where he should start looking, Sheila Templar thought. to be nocturnal, hiding in caves and rock crevices about 200 meters below the surface, there are hardly any maps of the seabed around New Guinea, because of the little information he has, Edmund decides to focus on a smaller island called Ravu in front of the north coast. I think Lulu looks to me on the maps to be probably the steepest and the few divers I've talked to talk about very large caves there so it could be pretty interesting too so that's the general habitat we're going to look for for general topography. or something like that, if the coelacanth lives in these waters it could have the right type of habitat that set this remote little Pacific diver on its way, if we can confirm the existence of silicates here in northern PNG it will actually be a very process A significant scientific finding will open up the possibility that, of course, silicates will be found throughout this western Pacific basin, so we are very excited about this possibility. 30 hours later, the ship arrived at its destination just north of New Guinea, which is about five kilometers long.

The team heads towards the shore along the way they meet a fisherman in his small canoe. He has just caught an oil fish almost two meters long. It is a deep-sea fish usually found at depths of around 500 metres. Where did you capture this? This is the place to Definitely a good sign. Good habitat for coelacanths. It appears that coelacanths and oilfish can be found in the same type of habitat. The Earthling and her team head to the local village to see if they can discover more. The island has a population of about nine hundred inhabitants. People, most of them make a living fishing, everyone thinks they are fish experts, right?

Yes, but this one we usually used to go get it at night, but what about the sealing cap? Then Earthman meets a veteran fisherman who gives him a crucial opportunity. piece of information, have you ever seen that fish before? Did you catch it during the day or night? Was it also in the same kind of depth as this fish? Yes, pretty deep, yes, it was a long time ago or not, you recently saw this. The area administrator asks the fishermen to take them to the place where he ties the coelacanth. The warriors have a traditional way of fishing in the deep.

They tie a strip of leaf to a rock and use it as a weight to lower the line to 200 meters or more. After that it's simply a waiting game. The next morning a tropical storm is approaching. Despite the difficult conditions, the crew continues. preparing the submarine for another dive they want to get as close to the coast as possible so the plan is to follow the war reef coral into the depths once underwater they are protected from the storm above and discover that the reef drops down they are level of the face they go to the place indicated by the fisherman, a large fish lurks inside a crevice.

Could it be the coelacanth? No, it's not, it's some kind of group of fish. The team looked a little disappointed, but then a huge grouper swam up to the submarine window. It is a giant, perhaps a meter long, as groupers mature they have been known to molt. in deeper waters look inside the submarine fascinated by extraterrestrial visitors this is a first even for 200 meter Earthman systems it is the wrath of a fisherman you see it is the weight of a deep seed line this may be the place where fishermen they captured the coelacanth it could be stop looking at Lily right there there is another seed Lily confirms that they are now entering the twilight zone the threshold to the lost world creatures like this some and very far away among these waters are sterile and support very little life but something is floating towards the submarine as if it were a warning, another living fossil that was once common in the shallow seas, but now confined in largemeasured to the deep surface.

In the deer we have a nautilus. Its large shell contains gas-filled buoyancy chambers with which it controls its buoyancy and depth and moves by launching jets. water comes out through a siphon a form of jet propulsion the team has already had magnificent views of two primitive creatures it is a promising start they are now at a depth of 200 meters Oatman notes that the surrounding seascape is gradually changing the rocks are littered of holes These caves were formed thousands of years ago by wind and waves that eroded the limestone cliffs of a small island that has now sunk beneath the sea.

There could be a seed attempt hidden in one of these cracks. The team decides to embark on a systematic search of the caves day after day they dive for eight hours but it is not easy to find a fish hidden in the darkness reaching the shore of the holes and cracks in strong currents is a challenge, it seems like an endless task but Hundreds of caves have been found to have The coelacanth has already been fished to extinction in these waters or are too shy to reveal themselves. It's frustrating and they have nothing to show for their efforts, but out of sheer exhaustion, the team faced a difficult decision whether they should stay or move elsewhere after much consideration.

Earthman decides to take a chance on a new location they had to the east, towards the Cam-it Islands, 200 miles away, in the Pacific, the Conneaut Islands are still uninhabited, untouched by man, the coral reefs are healthy and well preserved and waters rich in marine life. Birdman's hope said that here in these crystal clear waters they can find the creature they are looking for. The submarine descends into the crystal blue water. The team has its hopes. at a height even of 200 meters, the light still penetrates the water is exceptionally clear, the team is amazed by the large number of fish at these depths, it is unlike anything they have seen before, suddenly they find themselves with a whole complex of caves that open both large and small.

They line the surface of the rock some are so large that the submersible could easily fit inside the large grouper disappears into a hole this space definitely has potential White Point was rich in interesting caves but the strong current to find its quarry has brought with it a new trick It is a compact camera called a drop cam that can be taken to the depths. The rear

part

of the target is tied to the front of the camera and within minutes it attracts attention. A huge grouper has torn the bait bag along with the arm from the surface.

From the Lydia platform we have just been attacked by a very large grouper and it tore off all the bait from the front of the frame on the mother ship. The technicians rushed to build a second system, they managed to assemble all the pieces and even replace the frame with a stronger one, ok, the camera is mounted again and the contraption will be left for the next 24 hours. The Dropcam uses red light. Deep sea creatures cannot detect. This should allow us to see the animals behaving naturally. The Nautilus has been attracted by the bait and is soon joined by another, the newcomer seems to be watching the first with interest now it is trying to get the first off the hook with strong-arm tactics and jet propulsion, it rips its rival off.

The food is a surprisingly vigorous battle between these two living fossils in the depths. The food is so scarce that every bite is bitterly contested. The large bag of bait continues to attract others and assumes the center of a feeding frenzy. It is the last day of the expedition aboard the elucha Preparations are underway for the final dive. The dome is cleaned well and the crew also decides to change the submarine's lights. One light is replaced with a red one as it works so well with the flip top that it can decrease visibility a bit. but he will make sure that they do not scare away the animals.

We are still optimistic. We could get the mirror. We are looking forward to this last dive and have our fingers crossed that we will get there. It has happened before the surface. Lydia two one zero have entered the twilight zone. It's time to change. Turn off the combat lights leaving only the red is working, the scene of the fish unfazed by the large submarine above them and then a huge soldier attacked the fish. A ferocious predator like this would probably scare away any coelacanth in the area. Bertrand decides to shoot down the submarine even Beyond this depth, there are practically no pitching plans and almost no sun, it seems unlikely that they will find anything here, just when the crew is debating whether to return in a straight line, there are a couple of them saints , is this, this, this, this, could be, this is who. it's baked good, at least I think you know, let's make sure, let's make sure, let's make sure they have something, they make sure that something else, there is something, they have something strange, what is this, that is, that is, that's not a Sealy, that It's something else. but maybe right behind him, a strange animal look, but there is a second one above which you should film this.

It is a creature that man on Earth has never seen before. Swim slowly along the sea floor. It has a large head like a coelacanth, but a spotted body and underneath. On its belly there are strange appendages or antennae. The terrestrial has no idea what this fish could be. Is it possible that it is a new species? There is amazement in the control sound, as if there is a fan. Is exactly? The strange fish shows few signs of fear even when underwater. A second is approaching, lurking further back in the shadows. The shepherds are fascinated and decide to follow the mysterious creature, but to their surprise, the fish begins to swim towards them.

It seems to be interested in the submarine. It is a close encounter with the Third. It gets a little closer and thinks of shelter for two-meter fish as it passes over it, clearly extending its curious appendages. Could he be using them to feel the surface of the dome and then even swim upside down? It clearly has structures similar to three and 10a on both sides. of the tripod antennae of the body the fish seems to caress the rock with its antennae as if exploring the surface the longest antennae extend just beyond the fins and the animal is able to move them at will the tips of the strange feeders are flattened until they form a point and they seem to be soft and tactile if we want to film with red light yes, yes, the manager switches to the red light to see if the animal behaves differently, it slowly heads towards the back of the cave, it seems having lost interest in the Sun and continues with its normal life swims towards a narrow crevice although they wait it does not seem to come out again this must be its home circling slowly around it seems to be checking its surroundings gently probing the walls with its probes in search of creatures that They live in the dark other senses like touch become more important Berkman is intrigued about what this strange creature is.

The crew on the surface try to identify the fish from the information they have received from the submarine and conclude that it could be a new species that was recently described. In fact, it turns out that the fish was first discovered in Japan in 2008. The specimen is kept at the Kanagawa Natural History Museum dr. Hiroshi Cirno, who first described it, explains that it is a very rare type of deep-sea fish, it has a skeleton made mainly of cartilage and a strange soft, gelatinous nose. There are only four recorded specimens of this gelatinous nose in the world.

This is one of them. Dr. Cirno points out that its strange pelvic fins, which are typical of the species, have evolved into three long, narrow fin rays that look like antennas, almost certainly the same fish that the terrestrials and his team found in the depths. . I think that this video that we were able to capture of the jelly nose is probably, in many ways, more valuable than any video of coelacanths, given that this group is very little known and images of that quality do not really exist and, in fact, the Most of the photos and videos we have are simply of dead specimens, so these are truly spectacular images and I think you will be able to learn a lot about this special group of jelly-nosed fish that hides in narrow caves deep in the ocean. , which is why perhaps it was not captured until In the 21st century, even today we know practically nothing about it and how it lives in the teeth.

The images from the expedition provide the first clues as to how this curious fish could have managed to survive at such depths. A tiny fish swims up to the cashier's nose and briefly comes into contact with his sensitive sensors. Surprisingly, the gelatinous nose does not react even though food is scarce in this environment. Gelineau showed no signs of feeding during the four hours the team spent. followed it, like many deep-sea fish, it seems to conserve energy. It swims very slowly in cold water and can therefore survive on very little food, but how did the cella nose come to live in one of the most inhospitable places on earth?

Genetic analysis suggests that their ancestors evolved in shallow seas about a hundred million years ago. At first they thrived, but were then pushed into deeper waters by the arrival of powerful predators. In this impoverished environment, they evolved into periods of famine and this may be how the Gelinas survived the extinctions suffered by many other species on Earth 66 million years ago. the dinosaurs ruled the land and the seas the gigantic meteor ten kilometers in diameter collided with our planet with catastrophic consequences the intense heat burned more than half of the Earth's forests the diode tsunami devastated the country this may well be what wiped out the dinosaurs The gentle waves of the impact released underground sulfur into the atmosphere that turned into deadly acid rain.

The sulfuric rain wiped out plankton and shallow seas and many marine animals, including the Plesiosaur, are thought to have died of starvation. However, acid rain never reached the atmosphere. Deep down, it was neutralized by seawater on the way down, so many creatures living in the deep sea were able to survive already adapted to living in a dispersed environment. These animals now had an advantage by moving slowly to conserve energy and be able to withstand periods of starvation. the ancestors of the genna survived in the deep, that is certainly Edmunds theory, it is clearly something from the lost world, it seems that these animals actually have a behavioral ecology that is very similar to that of sila cats, so They live inside caves.

It's well camouflaged against the back of the cave floating there, but if it gets disturbed it will come out from our limited observations from the submarine, it seems like these fish are probably quite dependent on the caves they live in, so I'd say the caves are probably a very important

part

of their habitat the year-long investigation has come to an end Edmund and his team have discovered a lost world of prehistoric creatures that still live in the deep waters of tropical seas the notice virtually unchanged 400 million ago From years of slowly floating in the dark water and seeing lilies standing upright at the bottom of the ocean, it is a world where time stood still and living fossils survived this arid environment where most sea creatures could not survive while cradling these animals. ancient in a virtual time capsule that explores these tropical seas.

Just 200 meters below the surface we found a unique and special place, unlike anything you have experienced before. The deep sea, of course, is a very vast area. Interestingly, very little exploration has been done in this region; It remains largely a mystery, but by using cutting-edge technology such as the Triton submersible, we have been able to shed some light on this unique place and understand this lost world much better, the surprising encounter with the strange fish, the nose gelatinous creature that lives an austere life in the The dark waters were the highlight of the expedition. He has revealed that the deep seas remain a mysterious and unexplored world.

More than 90% of our oceans are so deep that they are typically out of reach and remain the least known part of our planet. These images taken less than five years ago with the first recorded of that almost mythical inhabitant of the depths of the sea, the giant squid, its body measures more than twice the height of a man, its tentacles four times longer, no one before had seen it alive and its natural habitat filming it was a historic triumph now the scientists and cameraman who captured these incredible images have teamed up once again to further explore the lesser known part of our palate, they are armed with the latest in water technology depths and a new highly sensitive camera that can record images in almost total darkness.

The team heads to a deep-water gorge off the coast of California and this time they hope to reveal another of the amazing ocean creatures that shine in thedepths miserably, so bright, so thick. so dense that there are so many different types of luminous displays and with them the strange praying animals. This is a journey to the darkest frontier on Earth to try to unravel some of the secrets of these extraordinary burrowing lives on the west coast of California, 200 kilometers south of In San Francisco is Monterey Bay, world famous for the richness of its marine life. The cold currents of the Pacific bring a large amount of nutrients to the bay and would support large numbers of marine mammals, whales, seals and floating among the seaweed.

Sea otters floating calmly on their backs opening up. shellfish face down beneath the surface of the sea and is the largest underwater canyon off the coast of North America at more than 3,000 meters deep and rivaling the Grand Canyon in size the irregular wars of the Monterey Canyon drop abruptly and create a unique underwater landscape The cold, protected waters provide a home for many deep-sea animals and new species are continually being discovered between 200 and 1,000 meters deep. The light gradually decreases until it becomes darkness. This is the twilight zone where little sunlight penetrates. Many of the creatures that live here produce their own light.

The expedition plans to dive into this area granted by dr. Bruce Robeson, who has worked in Monterey Bay for many years and is a world expert on deep-sea animals. We have been studying this place for 25 years and still find new animals. It is like searching for treasure and you never know the nature of the treasure. The Rebbetzin himself has made many discoveries in Monterey Bay over the years, but he knows well that exploration here has only just begun and that all kinds of amazement can now await. The team will deploy their specially designed research device for their first exploratory dive.

It is unmanned but carries a camera that sends images to the surface via a cable here we go the pair of curious seals come to see the strange machine slowly descends into deeper waters now that it has entered the twilight zone so little light from the surface It reaches these depths that to our eyes, it is practically pitch black, it is time to turn on the subsites, it is a strange tape like Rome, we have column worms and they are very fun to watch because they go through all these contortions and make spirals in circles and loops, well that's what they look like, they never tie themselves in a knot they can't get out of and then another strange creature, now it's itself, the self, in fact, is not an individual, but a chain of almost 50 joined together, look, the sinks are.

Jelly-like filters that suck water through their tubular mouths and filter out small food particles. DJ, let's start with one and then Robeson has seen something else in the dark. It is a kind of comb-shaped jelly called excavated rows of small flapping hairs that run the entire length. Its body is a magical sight but it is not bioluminescence. The glow is mainly reflected in the light coming from the submersible. A small squid appears in the headlights. It hangs in the water waiting for its prey to be trapped in its long tentacles and has a remarkably large eye. such a small animal, many creatures here have enormous eyes that they need to be able to follow their prey or distinguish the shape of a predator in the almost total darkness and there are many of them in the open ocean, there is no place to hide the The submersible is now Halfway into the twilight zone, they hope to see a still little-known creature that lives at this particular depth and here is a fish called a barrel.

Its extraordinary head is enclosed in a transparent dome so that Japan can see clearly. Inside his eyes inside the transparent shield are huge and point upwards. Robeson first encountered this strange animal more than a decade ago. At this point, we were very excited if no one had seen one of these alive before, only specimens that had been caught in Nets and As we looked at it, we realized that it looked very different from all the specimens that had been collected by Nets . This transparent dome over the eyes has never been seen before. When you catch them in Nets, everything is scraped off, it was an extraordinary discovery and the A strange fish with a transparent head made headlines, while the transparent shield was thought to protect the eyes.

It was a puzzle how the fish could catch its prey with its mouth facing forward if it couldn't see what it was feeding on. It was a mystery that Robeson would also solve a few years later. Many of the creatures of the depths such as the barreleye fish defy the imagination and here is another one. The Black Sea devil is a species of anglerfish with a bony rod and a luminous lure hanging from it. perched on the top of his head, each dive to these depths brings new discoveries, it's a black fish, although, right there, fern, look, it's a deep-sea dragon fish, the red spot just under the eye is a photo of a light emitting Orkin, even Robeson has never seen it in action before well, let's do it the submarine has a special suction device it will do it's a catchy mine oh but it's not easy Robeson wants to bring it to the surface so he can study it mainly now You will have to act quickly, with the huge change in pressure, the fish may not be able to produce its light for long.

The deep-sea dragon measures only four inches long, but Robeson is interested in discovering how he began producing organs to seed the photo in action. We'll need some highly specialized equipment, the red light emitted by photo 4 is too weak to be recorded by an impressive camera, but the team has developed one that is six hundred times more sensitive, tested outside on a clear night, it produces a surprisingly sharp image from stars, so it should be able to detect light produced by bioluminescent animals. The team has set up the filming tank in a dark room with water that is kept at the same temperature as the depths of the ocean.

With a little luck, the dragonfish should behave relatively naturally. Under these conditions, under normal lights, the fascinating creature lives up to its name, it looks truly fearsome and the two photophores are clearly visible under each eye, but in the dark, the four photographs glow in unison, one red and one blue, and then a surprise. this is something that no one has seen before that is unexpected and it is interesting oh it is a spectacular display but what is its function it could be to scare a predator but no one knows we may not find the answer in many years yet my Roman essence is not limited to the ocean, it is found in terrestrial creatures, even in the air, fireflies turn on their lights to attract a mate, some forest mushrooms glow bright green, attracting insects, perhaps to distribute their spores, and at certain times of the year, beetle larvae emerge from termites. mounds and light them up like Christmas trees, but the depths of the ocean produce 90% of the creatures and we still know very little about why they do it.

The only way to find them in total darkness is to illuminate them with our own lights, but when we do that it is impossible to see the much weaker living lights that the animals themselves produce, so studying the phenomenon is extremely difficult. The mysteries are how they use it, what They say to each other with that light the problem was that we never had a camera that we could take apart and use to record bioluminescence and that is why it was so important for me to go down and see with my own eyes now that Robeson and his team have the opportunity to use the latest technology to address the problem they will be working on. from the same research vessel that helped the film crew find the giant squid the highly sensitive camera system that took two years to develop will now be actually tested the crew performs last-minute checks on the submersible before its dive in the Monterey submarine canyon at the type of depth at which they will operate, all precautions must be taken the camera is carefully installed on a support attached to the outside of the submersible finally everything is in place and they are ready to go. excited like a child, I know I'm going to have a lot of fun, medicine has spent a good part of his career exploring the depths of the ocean, but he still gets excited before every dive, welcome, thank you after your submersible, the nadia has been lowered into the water a Secondly, the deep rover also launches happily, yes, okay and the dive begins.

Its goal is to descend to a depth of 600 meters in the middle of the twilight zone. Soon the light levels begin to drop and they enter a dark blue world. adept at the 200 meters that descend yes, there is a quite long one, yes, this may look like a piece of rope, but in reality it is a huge colony of living creatures linked together, they are called siphonophores and they are relatives of jellyfish. Carnivores are very unusual creatures they are a colony of individuals all connected to each other we have found individuals that were 40 meters longer than a blue whale the longest creature on earth the individuals in the front contract and expel water simultaneously, so they slowly move to colony forward in jet propulsion the rest of the chain extends hair like tentacles to catch passing prey, there may be hundreds, if not thousands, of individuals in a single chain, each performing a particular function and occupying a particular place within the colony, just like the organs in our bodies.

The colony functions as a team, but how the individuals communicate with each other and coordinate their movements remains a mystery. Oh, there is color. Bonnyman, he is very pretty and reduces carbon emissions for a long time, but he is a great swimmer and as the submarine gets closer, he increases his speed. look, it just released its tentacles ah great, you got it, the little jelly releases its tentacles on purpose, it's a ploy to confuse predators while our eyes follow the discarded appendages on the collarbone. EEMA does its escape check on the deer that passes five seven zero meters descending on it the submarine approaches the 600 meter mark oh, stop finishing for Cynthia, so the story is about owls, it seems to be afraid of the bright lights of the submarine, so the director of operations decides to turn them off, they turn on a much weaker light, adjust the sensitivity of the camera and The fish reappears like many deep-sea creatures.

The alpha SH has enormous eyes that can detect the slightest trace of light, including the living light of its prey. The fish uses minimal energy and simply hangs in the water waiting for its prey. Swimming without having a camera with this sensitivity is very exciting because of the things that can reveal things that we don't even know we are here and that can appear for the first time again because we really can or there is a penis. The office is a comb jelly again in the submersible headlights it shines with refracted colors but what would it look like if the lights were off?

In the dark the railroad produces the most amazing intricate pattern of light throughout its entire body this is bioluminescence which is a great holy water beauty the striking red torpedo is a paraphilia jellyfish it is a voracious hunter that uses rigid tentacles to catch its prey but it also has another trick up its sleeve which is that it is a very luminescent animal when stimulated okay so it is not to scare it they change to a red light that the Jedi cannot detect and then it begins with a totally different performance, it begins to expel the small blue particles moving away leaving a trail of flashing blue lights.

What's happening in the cold tried to stay away from gelatin. but the currents created by the disturbed submersible's response is to reject its living lights, it seems that if threatened, the boy from Paris tries to trick a predator into following the glowing trail and thus allowing the jelly itself to escape hmm, there is a Tamapahore world, yes, the transparent one. The worm appears to call through the water with its bristly legs, but when disturbed it also rejects bright lights. Many other bioluminescent creatures appear and the crew is able to capture their displays with the new camera.

Living in this twilight zone, the depth ranges are very challenging for the animals that choose to live here because there are no rocks or trees or holes in the ground where the animals can hide. It is a truly three-dimensional space without limits or borders. Light is an extremely important way animals cope with the challenges of living here. The team has been underwater for almost eight hours, it is time to surface, two days of the expedition have already passed and they are awaiting the arrival of a visitor, Dr. Edith Widow is a world expert in bioluminescence. She has worked with Robeson many times over the years.

Anyway, I need our help. I came here. Oh yes, the winner was part of the John Squid expedition in 2012. There wasdeveloped an electric jellyfish that emitted flashing lights similar to that one. used by deep sea creatures who had helped a team lure in a giant squid so they could film it alive for the first time. Now Witta has brought some new devices that he has developed especially for this expedition. This is one of them, he calls it. a splash screen if deep sea creatures unknowingly swim in it, she believes they will produce bioluminescence and her special camera should be able to film it.

I can't wait to try out the new splash screen of what this camera will be able to do. I see why in those early days she didn't know what she was seeing and I hope that over time she has gotten around to it and can identify many of the animals by the types of flashes they produced, but I think it will be even easier to understand. do it now mr. Witter will be working from the submersible, the deep rover, and Robeson is preparing to descend the Nadia again this dive. They are planning to descend directly to the ocean floor.

Check my depth seven seven zero meters at the bottom Emmett after an hour. did it the bottom of the sea is full of fish nutrients that fall to the bottom and accumulate there attract a wide variety of animals this small sea can receive yes and sea feathers Arcana like creatures that anchor themselves to the bottom of the sea prefer deep waters where they are They are less likely to be deflected by ocean currents, but they are not safe from the submersible's robotic arm that glows when touched. This is a different type of marine pen. Produces a pulsating blue light.

Witta is eager to try the new splat. screen to see if that will stimulate animals to shine that might otherwise be missed, get ready for the screen, oh yeah, okay, as your eyes adjust to the darkness, you see the first wispy cloud, it's a jellyfish, and then As you get closer, you can identify it. and the ultra-sensitive camera is able to record the complex screen of her when she touches the screen, it produces a spectacular flash of blue light. The witness suspects that the function of this screen is not to scare away the enemy, he can transmit another message now that it brings. its electric jellyfish in action is programmed to emit the same light pattern as a higher right camera reveals that the blue flashes quickly attracted large fish and a gigantic deep-sea predator, a nearly 3-meter-long Pacific sleeper shark, Jenny appears to be preying on smaller fish who are, in fact, the real jealous enemies, so Jenny's flashing lights may be acting as a call for help, a sort of living burglar alarm.

She has this remarkable ability to produce this pinwheel of light, etc. Clearly, if it were a cry for health, then you would think that pattern would be very attractive to large predators. It's an intriguing idea. Meanwhile, Bruce Robeson is in the nadiyah and is making his own discoveries stop in the pending forums in all areas. This is a snake fish. It is a fearsome predator and it creates light, you see those dots along its belly, although there are still bioluminescent organs, rows of small photophores run along its belly and produce blue light from below, the fish lights up like the track of an airport, interestingly, many deep-sea creatures generate light at the bottom, why should it be like that?

It appears that the lights may actually help camouflage animals from predators lurking beneath them. One creature that uses its lights to this effect is the far flying squid. Hundreds of small photographs illuminate their bodies completely. This bright light scares off predators. A small amount of light from the surface filters into the twilight zone, so from below a black silhouette would be clearly visible and would be an easy target for deep-sea hunters. A predator from below looking for food could see. the body of an animal silhouetted against the illuminated waters above and would use that silhouette as a guide to attack and feed, but the lights of the squid prevent it from breaking its silhouette through a thick layer of water this effect from being even more pronounced and by controlling the intensity of its own light to match the background, the animal blends in with its contradictory environment although in reality it may appear light. hides many animals that live in this part of the ocean they eliminate that threat by producing light along their bellies and erasing their shadow so that they cannot be seen but there is a predator that is not fooled by this trick the barrel eye has evolved its own special hunting technique, it hangs almost motionless in the water with its large eyes directed upward searching for the faint silhouettes of prey above its heads.

The eyes are green because they contain a pigment that screams bioluminescence that other animals used to hide with so they don't get fooled. the counter-illumination of that violin essence, although no one has ever seen how the barrel-eye hunts, Robeson has studied the animal closely and has devised a theory: it feeds on small krill, another painting that some prey tried to hide using bioluminescence, but seen through the eyes of the power of deception has not worked the hunter can clearly see his prey the barrel eye sneaks up from below and as he rises to the level of his prey he turns his eyes the eternal darkness has caused the creatures that live here evolve in all kinds of ways and strategies that are completely different from the ones we use ourselves and one of the key elements is the ability to create light.

They simply seem strange to us because we are so used to living in a very different world that some are practically blind and rely on other senses to catch their food, while others have particularly large eyes that allow them to see in the dimmest light. Everyone has developed their own ways of dealing with the darkness, but most use bioluminescence in one form or another, so perhaps it's not surprising that nature's greatest light show occurs in the only place where there is continuous darkness control. control passing three zero zero meters deep the rover slowly heads upwards with the screen still extended it lights up with the glow of small creatures that come into contact with the network by freezing in the camera image it is possible to identify some of the animals that are creating the light these are copies of pods small crustaceans only a few millimeters long when threatened they can release a bioluminescent liquid they are one of the most abundant creatures in the ocean and the main source of food for many fish, these Tiny creatures may provide a clue to understanding why bioluminescence is so widespread in the deep ocean.

It has long been a mystery how deep sea animals produce light, but now science has discovered some of the answers Most deep sea animals produce bioluminescence with the molecule called Ceylon Terezin when it reacts with certain enzymes in their bodies produce light so bioluminescence may seem magical but in reality it is the result of a simple chemical reaction, but nevertheless there is a Lister most deep sea animals cannot produce this light-emitting substance on their own. light, then where does it come from? A Japanese researcher, Yuuichi Ober, may have found the answer. Boba has been studying deep-sea copepods and has discovered that one species in particular is capable of producing Ceylon Terezin. inside its body it is called mat Rydia

pacific

a we still don't know how many others can do the same but it is a clue where the luminous molecule could have come from but how is it that the same molecule is also found in many other depths - marine creatures, well, it seems that is read through the food chain.

Copy pods are the main food source for many shrimp and small fish, so the seal on the Terezin molecule will be transferred to the bodies of their predators, the shrimp in turn can pass the molecule to their predators, the squid and larger fish, which in turn are eaten by even larger hunters, so the light-emitting molecule could have spread from prey to predator and thus throughout the entire animal community from the deep sea, it is an extraordinary thought that the vivid light produced by some of the smallest creatures in the sea could be the basis for incredible light shows in the ocean.

The precise function of bioluminescence may vary. Some use it to intimidate their enemies, others to hide from predators or to ask for help, but the meaning of many of them. Their messages remain a mystery as the expedition draws to a close, the team embarks on one last dive to observe a particularly spectacular event that occurs every night, when the sun sinks below the horizon, it is a moment in which As large numbers of deep-sea creatures rise to the surface, the team hopes to film the spectacle and accompanying light show and to do so correctly they will deploy both submersibles when we reach 200 meters or perhaps a hundred, we must coordinate. and if there is a thick layer of luminescence, yes we should try to shoot each other as we drive through it, the submersibles are launched, one is still right as they descend deeper and night falls, once again they enter the world of darkness and it is not long before they travel through a large swarm of krill is rising the small crustaceans are on their daily migration towards the surface where they will feed on plankton others have also been hiding in deep water to avoid the predators there is now a mass migration of animals towards the surface where feeding is more abundant but this vast migration attracts some larger hunters.

It's an electric torpedo ray. They generally live near the bottom, but at night they come up to feed. It's 5:30 p.m. m. and the sun has set the submersibles are in position control control 200 meters with the submersibles suspended motionless at a depth of 200 meters but to really see what they have come for they need to turn off all the lights, let's try it. The first bright lights appear and the show begins with each passing minute, the fireworks get bigger, the submarines are now surrounded by light on all sides, yes, pretty good, yes, wave after wave of living lights burst from the tube , so copepods and krill are the same, no Meah, there is a suggestion that millions of shiny sea creatures keep appearing and among them there could well be other strange life forms that we have not yet found.

The underwater night sky is now illuminated by hundreds of shooting stars. The show continues for more than two hours and when it returns to the surface, the scientists are ecstatic. It is very interesting that you can actually see the different colors, but scientists have yet to discover the meaning of many of these living lights and how and why most of the animals in this vast volume are produced. make light and that much of it we still do not understand what it is used for, that is a great mystery that we have only just begun to explore and we continue to find new discoveries every time we go into the ocean, so yes, we have only just begun to find .

Find out what's down there to learn how these pieces of a gigantic puzzle fit together and function as an ecosystem. Yes, we are just getting started. The deep oceans and their mysterious light-producing creatures have long been out of our reach with help. Thanks to new technologies and the latest research, we are beginning to unravel some of their secrets, but many mysteries remain and we are still a long way from understanding what makes these wonderful living lights shine in the abyss.
