news continues at the top of the hour in the meantime we'll look at some of the sleek marine life of russia seas and aquariums don't go away. dolphins in the arctic white whales are the undisputed stars of russia's aquariums and while spectators by the marine mammals elaborate carefully practiced performances few know about their long journey from the sea to the show how and by whom are the animals caught what's the secret of their near flawless training. in whales actually communicate with human beings the creatures comfortable in their captivity. to unlock the many mysteries of marine mammals our journey takes us to the ends of the earth to russia's remote far east. off the shores of the sea of a foot's not far from the mouth of the mighty river

a string of uninhabited islands. this one is named for the famous soviet pilot. who crash landed there during in one nine hundred thirty six expedition. during the salmon spawning season the sea around the island is literally teeming with fish and this abundance of food attracts large groups of white whales. in summer these tiny clapboard houses home to both teams of fisherman and an expedition of the russian academy of sciences. to reach a totally new level in our research behaviorally white whale. disco still have very little information about male female interaction. we're not sure if they travel in separate paths of males and females with. the story of the groups are set apart by. the study of white whales discovered less ground than that

of the dolphin white whales are believed to be a sort of universal indicator for the state of arctic marine ecosystems. as for the third street season scientists are tracing white whale migrations with the help of specialized satellite transmitters. this method is practiced around the world and has already revealed that white whales withdrawal for the winter to the northern sea of and come back each spring. the transmitters have a hermetic plastic cover meant to operate in deep water battery life is between nine and twelve months. we are hoping to find connection with the populations in america when they split off how they interact today and whether or not to show they practice similar migrations. next to the fishing village closures for the white whales that have been caught to be trained to perform in aquariums this region is where the majority of white whales in the world's aquariums come from. weather

permitting we'll catchers go to sea first thing in the morning because the early hours of the most active feeding time for the creatures roaming the local base. they come alone or in groups. turn up here others near that. and over there and everywhere. that he hopes to affix one of the transmitters on this run but not every animal captured is fit for the purpose. he saved the trans meters for their larger wider whales because the gray ones are undersized and they're still growing. we prefer males because their migration

spread out. and we want to trace their roots. ship. three big boats carry specialized floating nets each seven hundred fifty meters long the trap is carefully laid so that when it in snares a group of white whales it and wraps on its own at speeds topping twenty kilometers an hour. motorboat circled the net and scare the animals preventing them from breaking loose. stuff done ok was put in. as they dried the net the will catchers close to try the first catch a young female she differs from an adult player smaller size and her gray color. yellow one two or two and a half meters. the female were like cheers.

young animals will adapt well in captivity this young female we've caught will be sent to an aquarium and. the meantime another boat has its own net to handle that catches fairly good aside from a young female therefore bigger whales to extricate them from the net they're being dragged towards the same to shore. the important thing is to avoid injury animals. often parts of the net have to be cut loose to free the whales more quickly. individuals are identified according to their sex size and approximate age just because it will. become the gypsy male. of course. the biggest animals are released because they're unlikely to adapt in captivity. louison him go sure we'll releasing thank you let her enjoy her freedom just instead for an aquarium with their tanks are too small for

a beast as big as she weighs about a ton and a half. thank. you. thank. one of these whales will be fitted with a transmitter the installation procedure is perfectly fine tuned the enemy indoors the piercing without much problem three plastic rods easily penetrate a thirty centimeter thick roll of fat that covers its backbone while the steel cords finally fixed the transmitter in place for one whole year it will supply scientists with invaluable information. the future aquarium stars start their journey from the sea in a specialized shirt like net it transports the whales while avoiding injury.

easy honey thank goodness again a little bit we just put the shadow of the next time here and there under the board this way he won't choke in the water a move get pulled out of the boat by the then drag him slowly to the enclosure the . two whales have been caught and three others were released the transmitter has been installed on one big male will take more than an hour and a half to cover the three kilometers back to the base moving any faster might keep the animals from breathing comfortably. she seems to be coping. up until the other one to. go but you can

say we are leading them under the board that. in recent years the end you will catch has been no more than thirty head and has been limited solely to this area. this. believe on a small scale for a. show like for example. always mass scale. before being placed in. the end have to undergo a medical examination they're carefully untied and freed from their transport. what are we going to do everything that's measured them broken and take the genetic samples i'd like to take lots samples from the big ones. linked in body

circumference measured with more precision. carefully takes a blood sample from the tail. pulse to know how meat the cold stare. everyone is eager to get the whole thing over and done with discern is possible the next step is to perform an ultrasonic test to measure. these to fifty eight. for the first and possibly most. seeds and trust must emerge in its place away from the thrill of the open ocean they can slowly be consoled by human companionship.

the first human. closures with the capture. he knows each one by sight and seems to share their problems as a cell and. so make the transition easily or they go ok the very next day they come they take food your playstyle painting at the platform and you could hardly get rid of them to all intents and purposes they all taste just these are usually males young males very sociable the girls are all delicate much more difficult. the trainer brings them pale after pale of fish the better adjusted ones have a formidable appetite and they're at an all you can eat buffet. so there's a key indicator for them is whether or not they show that always on the so.

i mean they come out also they try not just take the head out of tool. particularly to avoid showing. going if they try to snatch the fish from under the water but when they show the oh yes it's complete adaptation i think those are. the invaluable milliliters of white whale blood or immediately put to a wide range of tests sadly practically all white whales in the wild are infected with parasites in open water diseases are far easier to transmit than to treat during their first weeks in captivity the doctors make sure their cured the will also have some ailments that you might call social. dizziness. i don't think the tape a time to. be the next his female friend. and another male it was bigger

a slip or so using this particular female. but. it's here. or that they start learning how to amuse spectators or to serve science a brave new world one so unlike their own element lies ahead of them. the. question was that so much i was about to fade into i think one thing we haven't really told is to bring you the making of our

western ideas about economics trade and even democracy in the balance and what model. this small town of mali with three show on the black sea coast is home to an aquarium of the russian academy of sciences. many marine mammals are brought here out to their cause. they're placed under the watchful eye of doctors and learn to get accustomed to people to cooperate and be friends. but molly wood three she's not just for newbies it's like a resort for c.n.n. most from far and wide. right now two female walruses are undergoing rehabilitation here both have been treated for serious problems with their tusks. as well and has also come here to work with the marine mammals it's the focus is going to find out where the white whales is its true should get the young white

whale medina comfortably on the stretchers. aware of what's in store for her and calm in response to all the actions of the scientists so it's silicone suction cups with sensors are placed on the surface of her skin right above the brain. trying to pick up the echo of the electrical signals inches inside her brain which in some animals are still just fifteen to twenty centimeters under their skin. but. it's the lower jaw bone of the sea mammals is considered the best area for sound reception hydrophone is affixed to the white whales lower jaw bones and puts out a series of noise it's. our experiments is toast you know in basis of this because he doesn't feel and it's. like giving if i was to listen and listen to music how often our or now i'm just off of that she can swim again without any problems and

let this book with. the scientists watch the brain response to the sound impulse on the computer monitor the first research on dolphins was launched here in the one nine hundred sixty s. today new technologies present scientists with new opportunities a lot of facts are being gathered but many of the mysteries of sea mammals remain unsolved. for the mysteries of shoop everything is a mystery here really. from here sounds ten pitches higher than the human ear can pick a researcher why can't people hear it with the majority of animals have only one zone of canine eyesight. dolphins have to. be underwater and the other one to see out of water. that's their trick. and they have a navigator a locator a sonar there how does the information that they received through the sonar and their eyes come together into one image you see. the experiment last for about an

hour the white whale marine it gets pretty bored without any tag. to perform but she also understands that people are working. probably more clever than dogs but not quite as smart as monkeys. and if you give a command to a dog it will do it but if you give a command to a dolphin or a white whale they will give you several options it's like they have a creative approach so. during breaks in the course of the experiment marina has to stay in the swimming pool alone and she gets restless. gets into the pool every day to play with the animals have a natural need for care and attention so in the laboratory nearby research is underway on the sleep habits of marine mammals right now behind the wall in the room with the swimming pool a seal is asleep he can sleep in one position for an hour or two without knowing

that the electronic equipment is registering all his cerebral activity. leaps on the side and keeps paddling with one slip through the day he changes sleeping positions and switches between the right and the left side proximately the same amount of time so that both sides of his brain get the same amount of. rain as all asleep at the same time but in case of marine mammals it's different to one hemisphere sleeps than the other. phenomenon was discovered here in the one nine hundred seventy s. . they live in the water and just can't afford to lose control of their surroundings for even one minute or they may face the threat of death that's why only one half of their brain is asleep and only one of their eyes closed we still don't know why they don't have the so called r e m a rapid eye movement phase of

the sleep cycle in other words they're incapable of dreaming by studying the unique sleep habits of marine mammals we can. stan some mechanisms of human sleep disorders. for example the absence of sleep we prove that whales and seals especially can go on without sleep for several days people also have the restless feet syndrome is when people move their legs and feet while asleep. the dolphins can actually sleep while swimming by and of course we hope that one day system will be able to understand what exactly happens to a person during his sleep which. lake which is the natural water reservoir that's connected to the seat it's less than a kilometer away. here in the natural pool there are several white whales that go through some very complicated training. animals are

taught to use the hydro coup stick system to search for people in distress and water through. on the trainers command the animal checks the whereabouts and points in the direction of a man behind me in closure through then another white whale on signal takes up a special mouthpiece exits the enclosure and promptly locates the man in the water at a distance of about three hundred meters. several of these animals behavioral tendencies a possible one check this is phil so he went to his trainer then located to go outside the enclosure with the acoustic device the neat little tidbit to manipulation the device compressed it will never fall in the direction in which there was a man in the water this is a complicated behavioral psycho when it needs practice to be perfect.

just one of the world's most. experienced marine mammal trainers he's been working with whales for some thirty years and seems to understand them perfectly. and a look at you will chance change the neo trying to attract our attention no additional but made underwater there's noises about. well he's getting multi they are very friendly to people on the show i think they are very easy to train with and establish europol with. by tradition the scientists the trainers the professors and the students all gather at five o'clock for a cup of tea but. it's here that they can discuss the news and hear about the most original scientific theories. danimal is work not for

a fair shake that they don't really need that much frankly speaking that they know very well they won't go hungry anyway and work for the sake of amusement their living creature opes i almost said peaceful. this truck has covered the distance of two thousand kilometers in two days inside is a huge basin with seawater and three white whales the future stars of the new aquarium soon to be opened in yet a slab. there about to be unloaded. this is a male way because his nickname is the three used to have a green on his tail so stretches included he weighs about four hundred fifty kilograms i've got his tail. good thank the entire male staff of the aquarium from the trainers to the plumbers and

accountants help unload the future performers i wrote him keep. yes just like that she. devil with the tail she can get you. one after another the animals leave the truck and start looking around their new home with curiosity these white whales were caught here and in russia's far east and spent their first year in the black sea where they went through a training course they handled the long trip pretty well. and transporting animals for fifty hours is absolutely the mission was over the last couple of years we worked out a method to transferring such animals over very long distances to where everything is falling and the animals are active in swimming. they will have the first feeding . the next important task for them is to adapt to the new conditions first they'll rest before they start their training which will be the same as here in st

petersburg special marine mammal querrey and one of the largest in russia. olga the veterinarian his return from the sea of cortes and is now back to monitoring the health of her performers. this is the only niche come. this far eastern white tway that you still eat in the c.e.o. scott. and this is a bottlenose dolphin from the black sea cow name is moves that she's the most beautiful ones or at least that's what she thinks instead. she knows full well how it's useful human beings can be. in between shows the trainers go through their routines with their animals over and over again to give commands trainers use only whistles tuned to this special range of frequencies that the dolphins can pick

up the enemies devote their undivided attention to the train or otherwise. they'll be no mutual understanding something. good communication is established gradually innocence and when you start training these animals when you feed. their first commands. slowly gradually you begin to understand option and when you might as well as they begin to understand you after that the work is mainly about learning each other's instincts and if they can see. the female dolphin does she gets distracted often by her six month old son on the arrival of new generations brings both great excitement and added responsibility to the aquarium dutch is a very protective mother and everyone here seems keen on spoiling their favorite little ne on. such

a diver loves to play with him in the water only with his permission of course no one appears set to be quite a performer since both his dolphin and human friends teach him everything they know . that infinity. has told him something. has to channel his mother to clanchy it to dance he really does it very quickly to be sociable interesting and he considers us close friends just keep his first time. one performance after the other crowds are thrilled by the spectacle of dolphins and humans working together. find all the excitement inspired by the stars is a great deal of work. the trainers a chair takers also bear a solemn responsibility for the majestic creatures dave tamed.
