"The Amazon... a wilderness teeming with wildlife" "But one part is still totally unexplored" "Under the water." "Hidden in the river lie some of the fiercest and strangest creatures on Earth" "Man may have walked on the Moon but no one has journed to the very bottom of the Amazon" "Until now." "An expedition is searching for the animals hidden in the depths." "We're looking in the places that no one has looked." "We have the ability to see and film things that no one has ever seen." "We've not just scratched the surface of the Amazon, but we've gone beneath it." "And we're bringing back stuff that is going to make people go:" "WOW !" "But the world's greatest river doesnt give up her secrets easily." "Manaus, in the heart of the jungle" "Bristling with sailors and river traders." "It's day one for our explorers." "They're some of the most experienced divers in the world, but they're going where no one has ever dive before." "For the next 5 weeks this boat will be their home" "Their mission : to take the BBC cameras to this last great unexplored habitat." "In search of unique creatures of the deep." "The diving is led by Mike DeGruy professional cameraman veteran of "The Blue Planet" and 100 other wild life films." "We really are on a wonderful expedition" "We have the opportunity to take all of this gear and film things nobody's ever seen, nobody's ever head of" "We're really gonna do it." "Also on the dive team , explorer and naturalist Kate Humble." "It's the most beautiful boat." "I feel like i'm about take part in African Queen." "Their challenge is formidable." "The Amazon hides its creatures in water so deep and dark, that no explorers have ever succeeded in penetrating its depths." "Their journey will be through the richest rainforest on the planet" "A jungle where a million species hide." "But their adventure will take them to the Amazon no one has seen before." "Beneath the surface of this immense river." "4000 miles long, in places wider than the English Channel, it would take 100 years to explore the 5000 tributaries..." "They have just one month." "The multinational team of scientists and divers will have to overcome storms and setbacks to discover species new to science, film underwater giants and track down primitive flesh feeding fish." "Their 2000 mile journey will ultimately lead them to dive a black hole in the heart of the Amazon where , with underwater robots , they hope to find creatures hidden in the abyss." "Kate is an experienced diver" "She searched for sharks for the BBC progam but, like the rest of the team, it's her first time in Brazil." "This is really going to be my first rainforest experience." "and all you hear about is the enormous number of diseases that you can get." "Mike's made more that 5000 dives in every corner of the planet." "As far as difficulty is concerned this rankes right up there." "Other areas, like Antarctica, diving under the ice, has its own set of problems." "These are unique problems." "Everything kind of falls apart, nothing heals up properly and one little snag on your finger, will mean that your finger will probably have to be amputated." "On a good day, the visibility is terrible." "We don't know where we're going, we have no reference material and divers in this area, plus,...there are animals down there that can kill you." "The Anaconda grows to over 9 meters long." "and the cayman, weighing in a quarter of a ton just 2 of the man eaters that hide in this murky waters." "Over the next month the divers will come face to face with both of them." "There are 3 boats in the expedition : one for living, one for support, and one for diving." "Their fist mission is to travel to a remote tributary of the Amazon" "The scientists belive it is home to many rare species." "As they draw near to their destination, every second is spent preparing the equipment." "Safety is everything." "Most important of all, they must be able to talk to each other under water." "It could save their lives." "Every single person underwater can talk to each other, as well as talk to the boat wich is where Mike will be with our topside cam unit he'll be able to talk to us and we'll have great communication" "and I personally feel that the communication is the key to the safety of this operation." "The expedition has reached the first dive site." "The whole team is focused on the preparations, and the gear had been checked and checked again." "In these conditions there's no room for error." "The air is cloudy and hot, the river will be just as warm." "The aim of the dive :" "To discover just how much can be seen underwater." "It is a step into the unknown." "Despite the heat, for their own safety they must be covered from head to foot." "There's no way i'm not going in with all this protection, having heard what there is in there." "As they descend, the divers discover a different world." "The water is heavy with sediment, and they quicly loose sight of one another." "Anything could be swiming past them, and still not be seen." "The state of their diving gear allows them to stay in the water until night has fallen, but they still haven't seen a single creature." "It was so murky, i had a torch held to my computer and i couldn't see it this way." "You can't help but think these animals have developed a way to sense through the muck." "There will be no reason to know how to do that." "We don't live in a situation where the fartherst thing we can see in 15 inches away from us." "They do, If you can see anything down there at all then our cameras are a miracle...it's a miracle." "The team are in somber mood." "No one suspected the visibility to be quite so terrible." "The whole future of the expedition is in doubt." "But there's no giving up." "First thing next morning, the boat is pushed further up the river and into the unknown , in search of better sites." "The diving will be dangerous, the job of keeping everyone safe rest with the dive master Richard Bull." "In all the hair raising deep adventures diving I've ever done this is some of the most challenging I've ever come across." "We have great expectations piled up on our heads, to deliver unique images." "Ok, well, I'll take that challenge on, but what it means is we got to go to different places and dive and dive, and dive." "Powerful lights and high definition cameras are being used to cut through the murky Amazon waters." "But hi-tech gear brings no protection from predators." "Mike Pitts has spent his carier filming dangerous creatures." "I think if you can see something from a distance, you don't think half as much about it when you have that very limited visibility and there are on you before you can even do anything about it" "It's like you can see a tiger shark from 30 meters away, and you're happy, you're fine you can face it off, but in this low visibility it is a worry." "Proffesional divers train to stay calm in the face of danger and keep their fear firmly under control." "I'm not going in the water feeling 100% happy, but, once you have the camera in your hand, you're checking your focus, you're checking your lighting, you're communicating with your buddy" "If you let yourself start thinking about it too much you'll allways been looking over your shoulder, behind you and I'm sure we're gonna get moments where you get bumped by things down there." "But people who have spent their life by the river are not so relaxed about the dangers." "Samuel Basilio and Eduardo Gomez are two local guides on the expedition." "Their expert knowledge is essential to the success of the project." "I have to be sure that nobody gonna be hurt by anything." "and..." "I know that's my job... is to protect all the group." "I've spent all my life fishing, I've been in contact with them." "stingrays and snakes and electric eels." "I mean , they're really bad." "Every year local people are attacked and killed by underwater predators." "The divers are not immune." "The teeth of the red-belly piranha are razor-sharp and can easyly slice through a wet-suit." "The electric eel will discharge 600 volts if disturbed leaving a diver unconscious." "But for the people of the Amazon, there is another creature feared even more." "It lives in the depths of the river, and has never been filmed." "The giant Jau." "The Jau were not come to swallow men but maybe they got scared hit someone with their head pull you down...and this will be dangerous,...for sure." "They bite, and altough they don't have sharp teeth but they have big mouths, when they're very big, they can swallow anything." "Three friends of mine, they jump, and they decide to go swimming to the shore and one of them dissapeared, so... we never found his body... never." "The giant Jau has a terrible reputation for draging fishermen down into the depths, drowning them." "Report have come in to the expedition team, that Jau have been found further up river." "We heard from the village that they got some contact" "They caught two Jau catfish a week and a half ago." "Can we expect to actually find one under a ledge and we can get relatively close ?" "It's a unique opportunity to film one of the Amazon's most infamous animals." "You know about all these dangerous creatures, and the Jau is one of them." "You know about anacondas, you know about caymans, you know about piranhas but the reality is that none of us has actually seen what they can do." "You know, we haven't experienced it, so... in a funny sort of way, you're actually feeling a little bit... it will be fine, because the reality hasn't hit." "Kate sets off upstream, to check out the information." "As well as being part of the dive team, over the next month Kate has the added task of tracking down the wild life on the river margins." "This is just extrordinary." "A family of capibaras." "On the bank... is huge." "Amazonian rodents." "It looks like 4 young..." "I just know I'm not going to get back to the boats." "But you can't afford to stop for long." "She need to find a fisherman that has seen the Jau." "Back downstream the countdown has started for the dive team." "Oxygen supply pressure OK." "Computer electronics turned on." "Absorbant time-remainig OK." "Oxygen turned on." "Computer turned on." "Fine." "Batteries OK." "The pressure is on." "They must find the creatures concealed by the river's turbulent waters." "30 miles upstream, Kate has had a stroke of luck." "She's found a fisherman who's seen Jau." "In the murk, the divers can't find the Jau." "In fact they're struggling to find anything." "But then, something extraordinary." "Gradually in the gloom, a giant colony of sponges appears before their eyes." "Normally, these primitive creatures are only ever found in the oceans." "Looking closer, the divers slowly begin to make out camouflaged creatures motionless, amongs the sponges." "This prehistoric species wears an armor of sharpen scales as protection from predators." "Even their fins hides switchblade spines." "The river revealed an extraordinary array of catfish perfecly adapted to feel their way through the darkness with gigantic whiskas." "A whole community of exotic fish are hidden here." "And then, allmost buried from sight, the king of the river bed." "The giant freshwater stingray." "It's barbed tail laced with enough poison to cripple a diver." "A tantalising glimpse before it dissapears into the gloom." "The divers have been in the water for 3 hours now, and air is runing low." "Suddenly a little fresh water sponge appears." "So we kept going up the slope more and more sponges, more and more fish" "It's the first time this unique habitat is been captured on camera." "You keep reminding yourself that you're in fresh water by tasting it." "otherwise it looks like you're in the ocean, they're not supposed to be in rivers" "Everybody knows that... so that was pretty spectacular." "There's a sense of relief on the dive boat." "At last, they're started to find creatures." "But they all know, there are many more spectacular creatures to be discovered." "First thing next morning, Kate passes on her news." "I've got a treat for you." "I've got reports of Jau." "I've met a fisherman that caught one ... 36 kilos." "And he's pretty sure there's another one up there because he was descaling a fish... and this thing came out." "Togheter, they start on a journey back upriver, to the dive site Kate found." "They are followed by the rest of the dive team" "Togheter they set about making camp on the beach." "The water here is fast-flowing and strewn with boulders." "Perfect condition for Jau and many other fish." "The local delicacy... red belied piranha." "The turbulence from the waterfall causes a scum of natural foam." "The foam blocks out the light, and the divers drop into darkness." "The labirynth of ledges and caves are a perfect hideout for Jau." "A pike cyclide is captured in the spotlight as it swims for cover." "In a crevice, catfish shelter for hungry predators, and keep a watchful eye on the passing prey." "At last a hint of the incredible life hidden in the river." "They discover one of the most peculiar creatures ever found in the deep." "Knive-fish" "These quirks of evolution navigate in the dark waters by using a sixth sense." "Electrical pulses generated by highly adapted muscles." "They're so specialised, they can even talk to each other with their electrical signals." "And hiding in a sunken lobe, a price... one of the largest knive-fish in the world" "Called the Black Ghost, it is shy, nocturnal and rare." "And has never been filmed in the wild before." "There is still no sight of the Jau." "But in this maze of rocks and caves, its secret layer can be just feet away." "Fortunately, the piranhas are keeping their distance." "And now, with their air getting low, the divers are forced to stop their search for Jau." "A bit dissapointing... not to see the Jau." "I mean, it was a very very very longshot." "We found a lot of fish down there, and almost all of them hated the light, and were tucked away in nasty little rock or wood crevices." "So you couldn't get a clear shot of them." "I'm tempted to stay and dive in at least twice again tomorrow." "Well that's why we're here, we want to see Jau." "That's out goal, so anything that will increase our chances, I'm all for." "This is been really nice, after my first dive yesterday in that thick soup, to come here and actually see something living in the river..." "That was good." "Now, in the dead of night, the divers drop into the darkness, for one more attempt to find the giant Jau." "They know the creature is somewhere down there, watching them." "Tomorrow the expedition moves on to second fase." "They track down the endangered giant otter, swim with fresh water dolphins," "and come face to face with monsters of the deep."
