0:00:02 > 0:00:04My name's Steve Backshall.
0:00:06 > 0:00:09And this is Deadly Pole To Pole.
0:00:09 > 0:00:11Oh!
0:00:11 > 0:00:13From the top of the world to the bottom.
0:00:13 > 0:00:15Whoa!
0:00:15 > 0:00:18Deadly places, deadly adventures
0:00:18 > 0:00:20and deadly animals.
0:00:21 > 0:00:24And you're coming with me, every step of the way!
0:00:26 > 0:00:27Argh!
0:00:30 > 0:00:33I've developed a fascination bordering on obsession
0:00:33 > 0:00:37with the true icon of Deadly - the great white shark.
0:00:38 > 0:00:41So what better than to dedicate a whole episode
0:00:41 > 0:00:44of our Pole To Pole adventure to this perfect predator?
0:00:45 > 0:00:48We've come to the ultimate shark-watching location -
0:00:48 > 0:00:51Guadalupe Island, off the coast of Mexico.
0:00:51 > 0:00:55Over 4,000 miles from the North Pole, this is great white central.
0:00:57 > 0:01:00Heading out into the middle of the ocean,
0:01:00 > 0:01:03I will have an encounter with this lord of the sea like never before.
0:01:08 > 0:01:10I've been lucky enough
0:01:10 > 0:01:13to bounce up against one in a tiny inflatable boat.
0:01:13 > 0:01:14Wow! Next to me! Look at this!
0:01:16 > 0:01:19To see one from the safety of a shark diving cage.
0:01:19 > 0:01:22Agh!
0:01:22 > 0:01:23Even to see them leaping -
0:01:23 > 0:01:27breaching out of the water in one of the world's most impressive attacks.
0:01:27 > 0:01:29No way!
0:01:29 > 0:01:31Just one big smack!
0:01:31 > 0:01:33But this time, we're going one better,
0:01:33 > 0:01:35we're going to dive with a shark
0:01:35 > 0:01:37out in the big blue, outside of the cage.
0:01:37 > 0:01:41This is quite simply the greatest shark encounter on the planet.
0:01:44 > 0:01:45That is no exaggeration.
0:01:45 > 0:01:49Great whites are the largest predatory shark on Earth.
0:01:50 > 0:01:53With over 300 serrated, sharp teeth,
0:01:53 > 0:01:57they can snag and slice through prey.
0:01:58 > 0:02:00Their exceptional sense of smell
0:02:00 > 0:02:04means they can detect blood from miles away.
0:02:04 > 0:02:06And when they focus in, their streamlined,
0:02:06 > 0:02:10torpedo-shaped bodies and crescent-shaped tail
0:02:10 > 0:02:13propel them through the water at terrific speed.
0:02:19 > 0:02:23This mission is certainly not for the faint-hearted.
0:02:23 > 0:02:25It's coming back towards us.
0:02:31 > 0:02:35So, with no time to lose we get loaded up,
0:02:35 > 0:02:37as this boat will be our home for the next five days.
0:02:44 > 0:02:45We've cast off from the Mexican mainland
0:02:45 > 0:02:50and we're now heading straight out to sea, around about 240 miles,
0:02:50 > 0:02:53and the weather forecast is for high winds and high seas.
0:02:53 > 0:02:57We're going to be bouncing around all over the place.
0:02:57 > 0:03:02Our destination is Guadalupe Island, better known as Shark Island.
0:03:02 > 0:03:04An isolated, extinct volcano,
0:03:04 > 0:03:09it's one of the best places in the world to see the great white shark.
0:03:09 > 0:03:12It'll be a 24-hour journey through some very rough seas,
0:03:12 > 0:03:14but it will all be worth it.
0:03:31 > 0:03:34It was a rough night. I think we're all a little bit green now,
0:03:34 > 0:03:37but we've woken up to an absolute vision.
0:03:37 > 0:03:39This is Guadalupe Island.
0:03:39 > 0:03:42It's uninhabited, unimaginably wild
0:03:42 > 0:03:48and surrounded by an infinite expanse of big blue Pacific Ocean.
0:03:48 > 0:03:52And, down there, are dozens of the most-feared predator on Earth.
0:03:52 > 0:03:55It's a very, very special place indeed.
0:03:56 > 0:04:00Unfortunately, there's no time to enjoy the view.
0:04:00 > 0:04:02With just two days to complete our mission,
0:04:02 > 0:04:04we need to start drawing the sharks in,
0:04:04 > 0:04:06as stage one of this challenge
0:04:06 > 0:04:09will be to get a sense of the sharks from the safety of a cage.
0:04:10 > 0:04:14We're going to use the great white sharks' supersenses as a tool
0:04:14 > 0:04:16to attract them to come in close to us.
0:04:16 > 0:04:19They have an exquisite sense of smell
0:04:19 > 0:04:21and they'll be attracted from miles away
0:04:21 > 0:04:22by the scent of blood in the water.
0:04:22 > 0:04:24As soon as we see a shark in close,
0:04:24 > 0:04:27we're going to get down into the shark-diving cage
0:04:27 > 0:04:29and try and get a sense with the particular animals.
0:04:29 > 0:04:33Every shark has a different personality,
0:04:33 > 0:04:36so it will take time and patience to get to know the sharks
0:04:36 > 0:04:41and find the perfect candidate for me to swim out of the cage with.
0:04:41 > 0:04:45After a few hours, our first shark appears,
0:04:45 > 0:04:46tempted in by the bait.
0:04:47 > 0:04:49Shark coming round. Shark coming up.
0:04:54 > 0:04:56And it's hungry.
0:04:59 > 0:05:05Whoa! It's completely taken the bait all in one go.
0:05:05 > 0:05:08That whole, huge tuna, which was the length of my leg,
0:05:08 > 0:05:09gone in a mouthful.
0:05:12 > 0:05:15Wow, things happen really quick round here.
0:05:16 > 0:05:21So with no time to lose, we get kitted up.
0:05:21 > 0:05:23Hopefully, this shark is going to stick around.
0:05:26 > 0:05:30I head down, with Johnny the cameraman, into the cage.
0:05:31 > 0:05:36Even though this is just stage one, my heart is already racing.
0:05:38 > 0:05:42Sitting, waiting - for perhaps the greatest predator on the planet
0:05:42 > 0:05:45to appear from the deep - is a daunting experience.
0:05:47 > 0:05:50I'm starting to imagine things.
0:05:50 > 0:05:52I just keep thinking that I've seen something.
0:05:54 > 0:05:56But it's always just a shadow.
0:06:00 > 0:06:03Then, out of nowhere, one appears.
0:06:05 > 0:06:07Oh, shark, shark, shark!
0:06:09 > 0:06:11We have a shark!
0:06:13 > 0:06:16Boy, do we have a shark! It's a monster!
0:06:19 > 0:06:22- Where did he come from?! - I know!
0:06:22 > 0:06:27It's just incredible that in water this clear,
0:06:27 > 0:06:31where you can see for what seems like an infinity,
0:06:31 > 0:06:35a shark can just appear out of nowhere.
0:06:35 > 0:06:38And this animal must weigh over a tonne,
0:06:38 > 0:06:41probably four metres in length. It's huge.
0:06:41 > 0:06:45But, somehow, they still manage to surprise you.
0:06:48 > 0:06:51The reason for that is its camouflage.
0:06:51 > 0:06:53It's what's called "countershading".
0:06:53 > 0:06:59The shark is white below and greyish-blue above.
0:06:59 > 0:07:01So whatever angle you look at it from,
0:07:01 > 0:07:04it blends perfectly into its background.
0:07:04 > 0:07:07You don't see this stealth attacker approaching
0:07:07 > 0:07:08until it's too late.
0:07:10 > 0:07:11Ooh!
0:07:11 > 0:07:14He put on a burst of speed there.
0:07:14 > 0:07:17I'm just trying to suss out what this animal's all about.
0:07:18 > 0:07:22I think he might be a little bit feisty to get out of the cage with.
0:07:24 > 0:07:27But I do have another plan for this animal.
0:07:27 > 0:07:29I'm going to see if we can measure its bite
0:07:29 > 0:07:32using the Deadly bite-meter.
0:07:32 > 0:07:35I've never tried a bite test gauge with a great white before,
0:07:35 > 0:07:39but I have done it with a lemon shark
0:07:39 > 0:07:40and it swam away with my gauge.
0:07:42 > 0:07:46Oh, no, no, no, no, no! He's got my pole!
0:07:47 > 0:07:49So I've learned my lesson.
0:07:49 > 0:07:51This time, I'm tying it on with some rope.
0:07:53 > 0:07:57Oh, and he's coming straight in for it! He's coming in for it already!
0:07:58 > 0:08:03Got very, very close on his first pass.
0:08:03 > 0:08:06Unfortunately, the bait seems to be more to the shark's taste
0:08:06 > 0:08:08than our gauge.
0:08:12 > 0:08:15Pretty close, pretty close!
0:08:16 > 0:08:21And so much explosive power,
0:08:21 > 0:08:24coming out for a few tries with that tail.
0:08:26 > 0:08:30I tell you what, with this shark, I am very, very glad
0:08:30 > 0:08:34that I've got the safety of these bars between me and him.
0:08:34 > 0:08:39But, again, the shark is only interested in the bait and the cage.
0:08:40 > 0:08:42Good grief!
0:08:44 > 0:08:48I guess it just looks a bit weird. It doesn't look like food.
0:08:49 > 0:08:53I think we'll call the bite-test gauge a noble failure.
0:08:54 > 0:08:56Well, that was a great start,
0:08:56 > 0:08:59but the main one that's hanging around right now,
0:08:59 > 0:09:01I think, is perhaps a bit too aggressive.
0:09:01 > 0:09:04I wouldn't feel comfortable swimming out into the water with him,
0:09:04 > 0:09:06so I think we are just going to need a little patience
0:09:06 > 0:09:09and, while we're waiting, the perfect way to spend our time
0:09:09 > 0:09:13will be to go and see what brings great whites to Guadalupe.
0:09:13 > 0:09:15I want to go and see their prey.
0:09:17 > 0:09:19So the crew and I head right up to the cliff edge
0:09:19 > 0:09:23as, when you're the prey of a big apex predator,
0:09:23 > 0:09:25you never want to be far from safety.
0:09:28 > 0:09:29There's an animal that occurs here
0:09:29 > 0:09:31that lives in the world of the great white
0:09:31 > 0:09:32every single day of its life.
0:09:32 > 0:09:35It's a true survivor - the Guadalupe fur seal.
0:09:37 > 0:09:40This is a really dangerous place for fur seals to make a living.
0:09:40 > 0:09:43I mean these incredible volcanic cliffs
0:09:43 > 0:09:45just drop straight down into the sea
0:09:45 > 0:09:48and then go down to real depths very, very quickly.
0:09:48 > 0:09:50It means that the only place they can truly be safe
0:09:50 > 0:09:53is right up close to the shore.
0:09:53 > 0:09:56I've dived in dozens of seal colonies around the world
0:09:56 > 0:09:58and, usually, sitting this close to the shore,
0:09:58 > 0:10:00you'd be surrounded by seals.
0:10:00 > 0:10:03They'd be dancing around in the water around you.
0:10:03 > 0:10:06But not here. The animals keep very, very close to the edge
0:10:06 > 0:10:08and that is for a very good reason.
0:10:15 > 0:10:17One, two, three, go!
0:10:19 > 0:10:21I'll need to get to the bottom quickly,
0:10:21 > 0:10:23so I'm safe from becoming prey myself
0:10:23 > 0:10:26and can enjoy this magical environment.
0:10:27 > 0:10:31Wow! What an extraordinary place!
0:10:33 > 0:10:37This is right at the edge of the world
0:10:37 > 0:10:42of the Guadalupe fur seal and the world of the great white.
0:10:46 > 0:10:48There is so much life here.
0:10:51 > 0:10:55It's like being in the world's greatest-ever aquarium.
0:10:57 > 0:10:59Oh, look at this!
0:11:01 > 0:11:04In no time at all, I'm surrounded by fur seals.
0:11:07 > 0:11:11There are two very distinct groups of seals.
0:11:11 > 0:11:13There are the true seals
0:11:13 > 0:11:17and the fur seals and sea lions, the eared seals.
0:11:18 > 0:11:24You can see these have external ear openings
0:11:24 > 0:11:27and long, broad flippers at the front of the body
0:11:27 > 0:11:29that they use for propulsion.
0:11:34 > 0:11:36Very inquisitive, this one.
0:11:38 > 0:11:40Look at her, what a beauty!
0:11:43 > 0:11:44Hello.
0:11:52 > 0:11:55I think she could see her reflection in my mask.
0:12:06 > 0:12:09How good is this?! Absolutely amazing!
0:12:19 > 0:12:23They make everything underwater seem so effortless, don't they?
0:12:23 > 0:12:27I would give anything to be able to swim like that underwater.
0:12:41 > 0:12:46But no matter how hard I try, I just don't seem to have the same grace.
0:12:54 > 0:12:57These fur seals might just look like they're having fun,
0:12:57 > 0:13:01but, for them, life is all about one thing -
0:13:01 > 0:13:04surviving great whites.
0:13:06 > 0:13:10I mean, once you're in the water, they hang at the surface
0:13:10 > 0:13:13with their heads and those big eyes looking down,
0:13:13 > 0:13:17always on the lookout for a shark.
0:13:20 > 0:13:22They're incredibly fast,
0:13:22 > 0:13:26agile, manoeuvrable creatures. But they have to be.
0:13:27 > 0:13:30As to escape a great white, you need to be quick.
0:13:34 > 0:13:37But fur seals are predators in their own right.
0:13:37 > 0:13:41All over the world, they use these same skills to hunt prey.
0:13:44 > 0:13:48With their speed, agility and lion-like teeth,
0:13:48 > 0:13:52they can catch food in all kinds of shapes and sizes with ease.
0:14:04 > 0:14:08And in Guadalupe, they have an added challenge for when they're hunting.
0:14:08 > 0:14:12Unlike many seals or sea lions, they hunt at night,
0:14:12 > 0:14:15because the great whites are much less active then,
0:14:15 > 0:14:19for things like squid and lantern fish.
0:14:20 > 0:14:22They're quite sneaky.
0:14:23 > 0:14:27This one keeps trying to creep up behind me and bite my fins!
0:14:32 > 0:14:36This animal has had to face so many challenges
0:14:36 > 0:14:41in its life here in Guadalupe -
0:14:41 > 0:14:44from the great white sharks it shares the seas with,
0:14:44 > 0:14:47to having to hunt in waters
0:14:47 > 0:14:50where everything can see them coming, they're so clear.
0:14:53 > 0:14:57But they are such sublime predators,
0:14:57 > 0:14:59they still manage to succeed.
0:15:02 > 0:15:04Oh, they are stunning!
0:15:10 > 0:15:13They're beautiful, they're playful,
0:15:13 > 0:15:15they're balletic,
0:15:15 > 0:15:17but they're also deadly.
0:15:22 > 0:15:25With strong jaws to catch fish food,
0:15:25 > 0:15:27agile, fast and furious.
0:15:29 > 0:15:32Sneaking up on their prey unnoticed.
0:15:32 > 0:15:34They might be cute,
0:15:34 > 0:15:36but they are also deadly.
0:15:37 > 0:15:39'(Deadly.)'
0:15:45 > 0:15:50Well, I would say there are few more beautiful dives
0:15:50 > 0:15:52in the whole world than that.
0:15:52 > 0:15:56But I reckon we've had our fair share of beauty now.
0:15:56 > 0:15:58Now it's time for the beast.
0:16:01 > 0:16:04But the sharks had disappeared for the day.
0:16:04 > 0:16:06So we'll have to wait until tomorrow
0:16:06 > 0:16:10to leave the cage behind and attempt the ultimate Deadly challenge -
0:16:10 > 0:16:12to free dive with a great white.
0:16:15 > 0:16:17Before I head to bed, though,
0:16:17 > 0:16:20I get the team together for a final briefing
0:16:20 > 0:16:23as, tomorrow, safety will be paramount.
0:16:23 > 0:16:24If I go to swim out the cage,
0:16:24 > 0:16:27then the first thing I do is get the OK from you,
0:16:27 > 0:16:30because you're much more experienced with this than I am.
0:16:30 > 0:16:32So you look at the shark, you suss it out,
0:16:32 > 0:16:34you figure out it's OK and then
0:16:34 > 0:16:36- you're going to be watching my back...- Yes.
0:16:36 > 0:16:38..and then I look down for that splash.
0:16:38 > 0:16:40And your last look should be looking down.
0:16:40 > 0:16:42Always look down first and then swim out.
0:16:42 > 0:16:44And, I guess, try and come alongside the shark
0:16:44 > 0:16:46- as it comes up to the bait?- Yes.
0:16:46 > 0:16:49But not in front of it. You don't want to be in front of the shark
0:16:49 > 0:16:52- and getting in-between it and the food.- Yes.
0:16:52 > 0:16:56Once the shark locks up on the bait, they don't change their minds.
0:16:56 > 0:16:59They'll go for the bait. Even if we are close by,
0:16:59 > 0:17:03they never change their minds, they just lock on the bait.
0:17:03 > 0:17:05Um, and, you know, obviously,
0:17:05 > 0:17:08we don't want to even think about things going wrong,
0:17:08 > 0:17:12but what is our kind of escape plan, if anything does happen?
0:17:14 > 0:17:16Oh, bottom line is something bad happens,
0:17:16 > 0:17:18we've got to get you out of the water.
0:17:18 > 0:17:22Because we're so far out from any type of civilisation, trauma centre,
0:17:22 > 0:17:25dive chamber. We've got to start evacuating you immediately.
0:17:27 > 0:17:28Any bite from any of these sharks,
0:17:28 > 0:17:30whether it be a juvenile or a large female or whatever,
0:17:30 > 0:17:34is going to be a catastrophic event.
0:17:34 > 0:17:36If someone gets bit, it's going to be catastrophic.
0:17:38 > 0:17:41'This could be a sleepless night for all of us.'
0:17:47 > 0:17:49So, today's the day.
0:17:49 > 0:17:51A lot of people might ask why I would even consider
0:17:51 > 0:17:54going outside of the cage with a great white shark
0:17:54 > 0:17:55and, for me, it's very simple.
0:17:55 > 0:17:58I've spent a lot of my life trying to convince people
0:17:58 > 0:18:01that sharks are not the misunderstood,
0:18:01 > 0:18:03man-eating monsters that a lot of people think they are,
0:18:03 > 0:18:06and this is kind of the best way of proving that.
0:18:06 > 0:18:08These animals have so much to fear from us
0:18:08 > 0:18:11and we have next to nothing to fear from them.
0:18:12 > 0:18:17Across the world, sharks are being destroyed at an alarming rate.
0:18:17 > 0:18:20For every person killed by a shark,
0:18:20 > 0:18:23around 10 million sharks are killed by man.
0:18:25 > 0:18:28From habitat loss to overfishing,
0:18:28 > 0:18:31to the demand for shark-fin soup,
0:18:31 > 0:18:33sharks are being decimated.
0:18:35 > 0:18:39By swimming with the greatest shark of them all, the great white,
0:18:39 > 0:18:40hopefully people can see
0:18:40 > 0:18:43that sharks are not the monsters they seem to be.
0:18:46 > 0:18:49But at the moment, we're playing a waiting game.
0:18:50 > 0:18:53So much of wildlife-watching is just about patience
0:18:53 > 0:18:56and waiting and this is no different, really.
0:18:56 > 0:18:59We are just staring off into the inky blue,
0:18:59 > 0:19:01hoping to see that distinctive silhouette of a shark
0:19:01 > 0:19:03popping up to the surface.
0:19:03 > 0:19:05But at the moment, it's just not happening
0:19:05 > 0:19:07and we're running out of time.
0:19:12 > 0:19:14So that we're ready when they do appear,
0:19:14 > 0:19:15we start kitting up.
0:19:23 > 0:19:26The important thing is that diving with whites,
0:19:26 > 0:19:29your heart always skips a beat.
0:19:29 > 0:19:32It doesn't matter how many times you do it.
0:19:34 > 0:19:39The enormity of what I'm about to do is starting to become very real.
0:19:40 > 0:19:42Shark, shark!
0:19:43 > 0:19:45This shark is definitely a player, this is perfect,
0:19:45 > 0:19:48this is one who will hang around if we play it right.
0:19:53 > 0:19:56It's really tricky, you've got to force yourself to go through
0:19:56 > 0:19:57all of your checks, your air,
0:19:57 > 0:20:00with the microphone, with the mask, with your fins -
0:20:00 > 0:20:03with all of the things that you have to have working
0:20:03 > 0:20:04just to do a normal scuba dive.
0:20:04 > 0:20:06But all the time in the back of your mind,
0:20:06 > 0:20:09is the fact that you're about to swim out in the open ocean
0:20:09 > 0:20:13with one of the most epic predators on the planet.
0:20:13 > 0:20:15Somehow, you have to put that to the back of your mind
0:20:15 > 0:20:17and focus on the important jobs.
0:20:20 > 0:20:22And I can't let nerves get the better of me,
0:20:22 > 0:20:24as animals can sense fear.
0:20:27 > 0:20:30I can't wait any longer. The shark is there.
0:20:30 > 0:20:31Are we ready?
0:20:33 > 0:20:36It's time to swim out into his world.
0:20:44 > 0:20:46This shark is known to the team,
0:20:46 > 0:20:49so we're confident we can open the cage door.
0:20:52 > 0:20:55But before I head out into the deep blue,
0:20:55 > 0:20:59we need to be absolutely sure this shark is on its best behaviour.
0:21:00 > 0:21:06It's an eerie sight, seeing a great white swim past you like this.
0:21:06 > 0:21:09with the door of the cage open.
0:21:15 > 0:21:20It's a male shark, but it's a mature male and of a good size.
0:21:22 > 0:21:24This is an animal that isn't going to have anything to prove.
0:21:26 > 0:21:28And the conditions are perfect.
0:21:32 > 0:21:36So I think it's time to head out through the open cage door.
0:21:41 > 0:21:43My heart is racing.
0:21:43 > 0:21:47Leaving the cage, I suddenly feel very small.
0:22:04 > 0:22:08They are so completely transfixing,
0:22:08 > 0:22:10almost hypnotising.
0:22:10 > 0:22:15But once you see one shark, you can't take your eyes off it.
0:22:15 > 0:22:17But the fact is, it's not the shark you can see
0:22:17 > 0:22:19that you have to be worried about,
0:22:19 > 0:22:21it's the shark that you don't see.
0:22:22 > 0:22:26So I'm very glad I have lots of eyes in the water.
0:22:26 > 0:22:29But even then, they can appear out of nowhere.
0:22:29 > 0:22:31One's behind you, Jose! One's behind you!
0:22:36 > 0:22:39Sharks aren't the mindless killers people believe them to be,
0:22:39 > 0:22:41but they're still predators.
0:22:42 > 0:22:44Even an exploratory bite from a great white,
0:22:44 > 0:22:47where they mean no harm, could be fatal.
0:22:49 > 0:22:52Coming back towards us, Johnny, straight at us.
0:23:05 > 0:23:08It's incredible -
0:23:08 > 0:23:14the power they can create with a couple of whips of that tail.
0:23:14 > 0:23:18So dramatic. And he's coming back round for the bait again.
0:23:18 > 0:23:23This is very similar to the way that white sharks here in Guadalupe
0:23:23 > 0:23:26have to go for fur seals.
0:23:28 > 0:23:30There's too much visibility here.
0:23:30 > 0:23:33They have to rely on sneak attacks,
0:23:33 > 0:23:35bumping into their prey,
0:23:35 > 0:23:38taking a bite then releasing, swimming away
0:23:38 > 0:23:41and letting it bleed to death.
0:23:41 > 0:23:44And their camouflage is so impressive
0:23:44 > 0:23:46that sharks simply appear.
0:23:47 > 0:23:49Look! Look at that coming straight towards us.
0:23:51 > 0:23:54Different shark, completely different shark.
0:23:55 > 0:23:58It's obviously been in battles with other males -
0:23:58 > 0:24:01it's lost an enormous chunk of flesh from its back.
0:24:05 > 0:24:08It's a newcomer. We haven't seen this one before,
0:24:08 > 0:24:11so I'm going to watch it very carefully
0:24:11 > 0:24:14before I think about swimming alongside it.
0:24:16 > 0:24:18In fact, I'm going to go back in the cage.
0:24:24 > 0:24:28But the new shark doesn't stay long before our other male is back.
0:24:31 > 0:24:36I have enough air left for one last swim with this incredible predator.
0:24:54 > 0:24:56This is quite simply wonderful.
0:25:00 > 0:25:05This shark is so at ease, gliding alongside me through the water.
0:25:15 > 0:25:18Beautiful, just beautiful.
0:25:25 > 0:25:27I'm not suggesting it's deadly
0:25:27 > 0:25:31because of its danger to people - far from it.
0:25:31 > 0:25:36But in terms of its mastery of the ocean,
0:25:36 > 0:25:38this creature is unparalleled.
0:25:51 > 0:25:56That is one of the great wildlife encounters.
0:25:57 > 0:26:00Unbelievable!
0:26:00 > 0:26:04To share the open water with a great white shark -
0:26:04 > 0:26:07probably the most feared creature on the planet.
0:26:09 > 0:26:10Extraordinary.
0:26:10 > 0:26:13I will never, ever forget this moment.
0:26:25 > 0:26:27What an experience.
0:26:27 > 0:26:29The great white is one of those animals
0:26:29 > 0:26:31that just seems to be perfect.
0:26:31 > 0:26:34Everything about it - its streamlining,
0:26:34 > 0:26:37its simple camouflage, its teeth,
0:26:37 > 0:26:38all of those supersenses.
0:26:38 > 0:26:42It's perfection. It just cannot be improved upon.
0:26:42 > 0:26:46And if you were a tuna or a seal,
0:26:46 > 0:26:49it would probably be the very last thing you'd ever see.
0:26:49 > 0:26:52To human beings, it does have the power
0:26:52 > 0:26:55to make us feel incredibly fragile and small.
0:26:55 > 0:27:00To everything else in the sea, it is deadly.
0:27:02 > 0:27:03Perfectly camouflaged,
0:27:03 > 0:27:07with one of the most feared mouths on the planet...
0:27:10 > 0:27:13..and with a streamlined, torpedo body...
0:27:14 > 0:27:15..it's perfection
0:27:15 > 0:27:17and definitely...
0:27:17 > 0:27:19'(Deadly.)'
0:27:21 > 0:27:23Join me next time for more Deadly Pole To Pole.
0:27:27 > 0:27:29It's coming back towards us, Johnny.
0:27:48 > 0:27:49'(Deadly.)'
