0:00:02 > 0:00:05My name's Steve Backshall!
0:00:05 > 0:00:09And this is my search for the Deadly 60.
0:00:10 > 0:00:13Amazing! That's not just animals that are deadly to me,
0:00:13 > 0:00:17but that are deadly in their own world.
0:00:17 > 0:00:19My crew and I are travelling the planet,
0:00:19 > 0:00:22and you're coming with me every step of the way!
0:00:26 > 0:00:27Agh!
0:00:30 > 0:00:34This time on Deadly 60, we are truly in a land that time forgot.
0:00:34 > 0:00:37This is Peru, and the Amazon rainforest.
0:00:37 > 0:00:41If we can't find deadly predators here, we might as well give up.
0:00:42 > 0:00:46The Amazon rainforest is almost the size of Europe,
0:00:46 > 0:00:48and we're based in the southwestern corner,
0:00:48 > 0:00:52on the hunt for the best that it has to offer.
0:00:53 > 0:00:56This awesome jungle contains around ten percent
0:00:56 > 0:00:58of all known species on Planet Earth,
0:00:58 > 0:01:02from the weird and wonderful to the downright deadly.
0:01:04 > 0:01:06So we're ending on a high
0:01:06 > 0:01:09in the best place in the world to find deadly animals -
0:01:09 > 0:01:13the flooded forest, a perfect home whatever your appetite.
0:01:16 > 0:01:19'After a half-hour paddle, it's a short trek to our jungle home.'
0:01:19 > 0:01:21Hi, there!
0:01:21 > 0:01:27'But we don't even get a chance to unpack before everything kicks off!'
0:01:29 > 0:01:32Richard spotted some giant otters.
0:01:32 > 0:01:34I'm going to go and try and join them.
0:01:34 > 0:01:38'We'd expected to work all week to find our first deadly animal,
0:01:38 > 0:01:41'but they've just swum straight past us!
0:01:41 > 0:01:44'They're hunting and already on the other side of the lake,
0:01:44 > 0:01:48'so we're going to need to mobilise.'
0:01:50 > 0:01:54Just over the other side of this lake
0:01:54 > 0:01:59is one of the most elusive but one of the most fascinating creatures
0:01:59 > 0:02:03found in the whole of the Amazon - the giant river otter.
0:02:03 > 0:02:06'This is no ordinary otter.
0:02:06 > 0:02:09'At two metres long, they're longer than I am tall.
0:02:09 > 0:02:12'They spend most of the day hidden in the flooded forest,
0:02:12 > 0:02:16'and any second could disappear before we can film them.'
0:02:16 > 0:02:19The only thing on our mind is getting to these animals
0:02:19 > 0:02:22before they disappear.
0:02:23 > 0:02:26'It's a long hard slog, and finally we can hear them
0:02:26 > 0:02:29'on the edge of the lake, but it seems hearing them
0:02:29 > 0:02:34- 'is far easier than seeing them!' - GROWLING AND WHISTLING
0:02:34 > 0:02:37So we follow their calls in the hope they'll emerge.
0:02:38 > 0:02:40WHISTLING
0:02:40 > 0:02:42'Giant otters are incredibly rare.
0:02:42 > 0:02:45'It would be quite an achievement and a real privilege
0:02:45 > 0:02:48'to see them up close.'
0:02:52 > 0:02:55Steve, Steve! Slow up. Stay there.
0:03:00 > 0:03:04'So when they finally emerge, we are beside ourselves.'
0:03:06 > 0:03:09The whole family out of the water, feeding together!
0:03:09 > 0:03:12CHITTERING
0:03:13 > 0:03:15This is just extraordinary!
0:03:17 > 0:03:20There's a group of about seven animals in front of us,
0:03:20 > 0:03:24and one of them has just made a kill.
0:03:24 > 0:03:28- And... Look, this branch here. - OTTER CRUNCHES
0:03:28 > 0:03:31And I can hear him crunching from here!
0:03:33 > 0:03:35I'm sweating like crazy. I'm all hot and bothered,
0:03:35 > 0:03:39and I couldn't care less! This is awesome!
0:03:40 > 0:03:43'But no sooner have we seen them than they're gone,
0:03:43 > 0:03:47- 'vanishing into the flooded forest.' - ANIMALS YOWL
0:03:47 > 0:03:51'And by the sound of it, something's kicking off.'
0:03:51 > 0:03:56This prolonged vocal thing that's going on behind us here
0:03:56 > 0:04:00is, probably, the otters have found an anaconda, a very big snake,
0:04:00 > 0:04:04- or a caiman, a crocodile. - WHISTLING AND HISSING
0:04:04 > 0:04:07I hope we're going to be able to see this.
0:04:08 > 0:04:11'By day, giant otters rule this lake.
0:04:11 > 0:04:15'There's nothing that would mess with them.'
0:04:16 > 0:04:18Oh, look! Caiman coming out towards us now!
0:04:18 > 0:04:21Just ducked under the water.
0:04:22 > 0:04:24Could be what all the fuss is about.
0:04:25 > 0:04:27It was just there.
0:04:31 > 0:04:33Keep your eyes open, guys.
0:04:35 > 0:04:39At two metres long, giant otters are a force to be reckoned with.
0:04:39 > 0:04:42They're highly territorial, ganging together to kill a caiman
0:04:42 > 0:04:46twice their size by cutting it open with their long canine teeth.
0:04:48 > 0:04:51And if that's not enough, check out their menu.
0:04:55 > 0:05:00Five-metre anacondas, giant catfish,
0:05:00 > 0:05:03even piranhas. This animal dominates the flooded forest
0:05:03 > 0:05:06with speed, aggression and teamwork.
0:05:07 > 0:05:11'And, as we've just heard, they'll happily take on a crocodile
0:05:11 > 0:05:13'and come out on top.'
0:05:13 > 0:05:16Look at that! Wow!
0:05:16 > 0:05:20The water's just parting in front of him. He's coming right up to us!
0:05:22 > 0:05:25You can see the power of them as they swim.
0:05:29 > 0:05:33'Inside their territory, everything makes way for the otters.'
0:05:33 > 0:05:37Local people call these animals river wolves,
0:05:37 > 0:05:39and it's a really apt name.
0:05:40 > 0:05:42Firstly you look in their mouths,
0:05:42 > 0:05:46and they've got canine teeth that wouldn't look out of place
0:05:46 > 0:05:48on a wolf.
0:05:48 > 0:05:51Secondly, they're the longest of the weasel family,
0:05:51 > 0:05:54and in weight - about 35 kilos -
0:05:54 > 0:05:57actually not that dissimilar to a wolf.
0:05:57 > 0:06:00And thirdly, they hunt in packs.
0:06:01 > 0:06:03This group moving along this riverbank
0:06:03 > 0:06:08are moving in unison, frightening and disorientating the fish
0:06:08 > 0:06:11and catching them down there in the dark,
0:06:11 > 0:06:13using their tactile whiskers to feel them.
0:06:14 > 0:06:19Giant otters are perfectly evolved for hunting in the murky waters
0:06:19 > 0:06:21of the Amazon basin.
0:06:21 > 0:06:25Their broad, wing-like tail is the perfect engine,
0:06:25 > 0:06:27allowing them to fly through the water,
0:06:27 > 0:06:30with webbed feet for fine control.
0:06:32 > 0:06:34And their eyesight is pin-sharp,
0:06:34 > 0:06:39but fishing blind is no problem. These awesome anglers
0:06:39 > 0:06:44use their whiskers to follow the wake of a fish long after it's gone,
0:06:44 > 0:06:47meaning prey can swim but it can't hide.
0:06:49 > 0:06:53By working together, a group of giant otters confuse their prey,
0:06:53 > 0:06:55giving it almost no chance.
0:06:55 > 0:06:59They're a deadly team both above and below the water.
0:06:59 > 0:07:01OTTER WHISTLES
0:07:04 > 0:07:08One, two, three heads come to the surface. Five heads to the surface.
0:07:08 > 0:07:11Three of them have got fish.
0:07:11 > 0:07:13That is incredible.
0:07:13 > 0:07:17You'd be hard-pressed to find any other predator in the world
0:07:17 > 0:07:20that has that kind of success ratio when they're hunting.
0:07:21 > 0:07:25- OTTER GRUNTS AND CRUNCHES - Listen to that!
0:07:27 > 0:07:32Just hear those fearsome teeth just crunching straight through fishbone!
0:07:37 > 0:07:40I may be a battle-hardened naturalist.
0:07:40 > 0:07:44I've seen lions hunting, orca, great white,
0:07:44 > 0:07:48but none of them come even close to being as efficient as these guys.
0:07:48 > 0:07:51And that's why they're going on the Deadly 60.
0:07:55 > 0:07:57How good was that?!
0:07:59 > 0:08:03Giant otters use super-sensitive whiskers to detect dinner,
0:08:03 > 0:08:06and teamwork to swim it down.
0:08:06 > 0:08:10But their size and aggression sets them apart from other otters,
0:08:10 > 0:08:12and that's why they're on my list.
0:08:18 > 0:08:22'So, with giant otters in the bag already, we're off to a great start,
0:08:22 > 0:08:26'and it's the perfect time to see what else we can find.'
0:08:28 > 0:08:32It's quite a weird sight, seeing these freshwater turtles stacked up
0:08:32 > 0:08:35one on top of the other like a pack of playing cards,
0:08:35 > 0:08:38just basking in the sun.
0:08:40 > 0:08:43'This is truly a land that time forgot,
0:08:43 > 0:08:48'and rammed with awesome animals - some harder to see than others.'
0:08:50 > 0:08:53- HE LAUGHS - How weird was that?!
0:08:55 > 0:08:58'But all these critters pale into insignificance
0:08:58 > 0:09:01'when we spot a true giant.
0:09:03 > 0:09:07'It has to be the next contender for my Deadly 60 list.'
0:09:11 > 0:09:15This prehistoric, chilling silhouette
0:09:15 > 0:09:17is a black caiman.
0:09:17 > 0:09:22It's the largest of the crocodiles found in Latin America.
0:09:23 > 0:09:27And it's incredibly difficult to judge the scale of it, the size,
0:09:27 > 0:09:31just from what we see now, which is little more than the head
0:09:31 > 0:09:35and the scute, the back of the neck, above the water.
0:09:35 > 0:09:39It could be three metres long, it could be two metres long -
0:09:39 > 0:09:41I don't know. What I do know
0:09:41 > 0:09:45is that this is definitely a very powerful animal.
0:09:45 > 0:09:47So what is it about the black caiman
0:09:47 > 0:09:50that makes it worthy of a place on my list?
0:09:51 > 0:09:55At up to five metres long, they're the kings of the Amazon -
0:09:55 > 0:09:58fast, furious fishing machines.
0:09:59 > 0:10:02And, unlike most other species on the Deadly 60,
0:10:02 > 0:10:06this one can, very occasionally, be a man-eater.
0:10:06 > 0:10:10These cunning crocs can work together as a team,
0:10:10 > 0:10:14corralling fish into a ball before taking turns to dive in for dinner.
0:10:18 > 0:10:21To give you a sense of the scale of a large black caiman,
0:10:21 > 0:10:24I want to entice one up out of the water.
0:10:24 > 0:10:27'Our plan is to use special surveillance cameras
0:10:27 > 0:10:29'to see one at night when they're really active,
0:10:29 > 0:10:33'and then head out on the lake to catch a more manageable youngster.
0:10:33 > 0:10:37'But to put this plan in action, we've got serious work to do.'
0:10:37 > 0:10:40This is perfect. Yeah, I reckon this is our spot.
0:10:43 > 0:10:47So, these here are camera traps.
0:10:47 > 0:10:51What we're going to do is probably tie these to some trees,
0:10:51 > 0:10:54put them all around this area here, and then put some bait,
0:10:54 > 0:10:57some nice smelly meat, down the centre there.
0:10:57 > 0:11:01And I think the idea is to set a trip-line up around here,
0:11:01 > 0:11:05and anything big that comes in here to check out that meat
0:11:05 > 0:11:07will trip the cameras,
0:11:07 > 0:11:10and hopefully we should get some shots of them on these.
0:11:10 > 0:11:14'So despite the downpour, it's time to get to work.
0:11:19 > 0:11:23'With infrared lights in place, camera traps at the ready
0:11:23 > 0:11:27'and tripwires armed, we just need some smelly bait.
0:11:27 > 0:11:31'This slightly stinky steak is perfect.
0:11:31 > 0:11:34'I love it when a plan comes together!
0:11:40 > 0:11:44'Caiman are most active at night, but they won't come to the bait
0:11:44 > 0:11:48'if we're here. So we're leaving the trap till dawn, when we'll return
0:11:48 > 0:11:51'to see whether we've been successful.'
0:11:51 > 0:11:56As the sun starts to set, this is a real changeover time in this lake.
0:11:56 > 0:12:00The otters will have headed into their holts, their dens,
0:12:00 > 0:12:03and they'll be laid up quietly for the night,
0:12:03 > 0:12:05and now it's the turn of the caimans.
0:12:05 > 0:12:11They become top dog - or top croc - on this lake.
0:12:12 > 0:12:16'And now it's dark, it's time to show you some young caiman.
0:12:17 > 0:12:21'These will hopefully be a much more handle-able size.'
0:12:21 > 0:12:24A lot of nocturnal hunters have a shiny, reflective layer
0:12:24 > 0:12:28at the back of their eyes, and when the light hits it, it shines.
0:12:28 > 0:12:31In crocodiles, it shines bright, fiery red,
0:12:31 > 0:12:34which gives a much better chance of finding them.
0:12:34 > 0:12:38'So my hope is to catch one, to give you a proper look.'
0:12:40 > 0:12:42There it is.
0:12:42 > 0:12:45OK. If the guys just send me straight in there...
0:12:54 > 0:12:55Ooh!
0:12:55 > 0:12:58Just moved a fraction!
0:13:00 > 0:13:05And he's gone. You can see how quick their reactions are.
0:13:05 > 0:13:08This place is absolutely crawling with caiman.
0:13:10 > 0:13:12'At only ten metres away...'
0:13:12 > 0:13:14There it is.
0:13:15 > 0:13:18Keep it dead on him. Don't move it.
0:13:30 > 0:13:32HE GRUNTS
0:13:34 > 0:13:36Right! Success!
0:13:38 > 0:13:44Now, the black caiman is the largest crocodile found in South America.
0:13:44 > 0:13:49Not, obviously, this one. This would probably be about a year old.
0:13:49 > 0:13:52The black caiman goes through several distinct stages
0:13:52 > 0:13:56in its development, from a hatchling to ones this size,
0:13:56 > 0:14:00which are still quite vulnerable. Plenty of animals would like to eat
0:14:00 > 0:14:04caimans of this size, so they tend to hang out around about the sides
0:14:04 > 0:14:07in these reeds and rushes where they're protected
0:14:07 > 0:14:11and feed on much smaller prey, insects and frogs and lizards,
0:14:11 > 0:14:14anything they can get into that mouth, which at the moment
0:14:14 > 0:14:17is lined with needle-sharp, tiny teeth.
0:14:17 > 0:14:21You can just see them spilling out the side of the snout there.
0:14:21 > 0:14:25However, as they get bigger, all of a sudden things change,
0:14:25 > 0:14:28and they start to really rule. When that happens,
0:14:28 > 0:14:32they're much more confident hunting out in the open of the lake.
0:14:32 > 0:14:34I think we'll let our little fella here
0:14:34 > 0:14:37go about his night's hunting in peace.
0:14:45 > 0:14:47Such beautiful creatures!
0:14:48 > 0:14:52Mind you, I certainly wouldn't be doing that with his mum.
0:14:52 > 0:14:55And certainly not his dad.
0:14:55 > 0:14:57'That is the job of our camera traps.
0:14:57 > 0:15:00'Tomorrow cannot come soon enough.'
0:15:06 > 0:15:09It's a beautiful, still, windless morning,
0:15:09 > 0:15:13and we're just heading back to the camera traps.
0:15:13 > 0:15:15They're in the bushes ahead of us.
0:15:15 > 0:15:19There's quite a heightened sense of anticipation among the team
0:15:19 > 0:15:22as to what's going to be on the cameras.
0:15:24 > 0:15:27I can still see the cameras. They've not been eaten by anything.
0:15:29 > 0:15:32The tripwire's gone.
0:15:38 > 0:15:40Meat's gone!
0:15:42 > 0:15:44No way!
0:15:44 > 0:15:48OK! Let's have a look at what we got.
0:15:51 > 0:15:55This is really exciting. We've got something on here.
0:15:57 > 0:16:00CAMERA WHIRRS
0:16:00 > 0:16:04Been triggered by something, but I can't see anything.
0:16:04 > 0:16:09'But as the tape goes on, it seems as if the traps have malfunctioned.'
0:16:09 > 0:16:11Oh, dear.
0:16:12 > 0:16:14Is that the end of the tape?
0:16:14 > 0:16:17Almost, and there's nothing there.
0:16:17 > 0:16:20'We're all gutted.'
0:16:25 > 0:16:27HE SHOUTS IN DELIGHT
0:16:28 > 0:16:31Look at that!
0:16:31 > 0:16:33That's fantastic!
0:16:33 > 0:16:36Right at the end of the tape!
0:16:38 > 0:16:42Look at that! It's a huge black caiman! Look at the size of it!
0:16:42 > 0:16:47- You got to see this, guys. You got to see it.- Unbelievable!
0:16:47 > 0:16:49'At over four metres long, this giant must weigh
0:16:49 > 0:16:52'more than all of us put together.'
0:16:52 > 0:16:55- You wouldn't want to go swimming in there.- No.
0:16:55 > 0:16:57No, you really wouldn't.
0:16:57 > 0:17:00Black caiman are the largest members of the alligator family.
0:17:00 > 0:17:05A really broad, flattened snout, very, very powerful around here,
0:17:05 > 0:17:08which allows it to use those jaws with great strength,
0:17:08 > 0:17:12wrenching its prey around. At the moment it's just slinking off
0:17:12 > 0:17:15back into the water with our meat.
0:17:15 > 0:17:17That is an absolute triumph.
0:17:17 > 0:17:20On this lake we've seen all different sizes of black caiman,
0:17:20 > 0:17:24from tiny little hatchlings right up to the absolute monster.
0:17:24 > 0:17:29And, looking at this, black caimans have got to go on the Deadly 60.
0:17:31 > 0:17:35The black caiman is a true giant of the Amazon rainforest.
0:17:35 > 0:17:38It uses intelligent teamwork to confuse its prey
0:17:38 > 0:17:41before diving in with crushing jaws -
0:17:41 > 0:17:45a clever killer that's armed to the hilt.
0:17:50 > 0:17:54'So, after an action-packed morning, we're 59 animals down,
0:17:54 > 0:17:57'but with only one day left, and our last spot on the Deadly 60
0:17:57 > 0:18:01'is still up for grabs. Come on, Giles - we've got work to do!
0:18:02 > 0:18:06'The Amazon jungle is legendary for huge snakes,
0:18:06 > 0:18:09'and I'm really hoping to end on a high by finding one,
0:18:09 > 0:18:11'on land or in the water.
0:18:11 > 0:18:14'But planning is pointless on Deadly 60.
0:18:14 > 0:18:17'We'll take any opportunity we get.'
0:18:18 > 0:18:22Just had a shout from one of the guys working at the place
0:18:22 > 0:18:24we're staying at, that there's a big lizard
0:18:24 > 0:18:28trapped in one of their septic tanks.
0:18:28 > 0:18:31Going to go and have a little look and see what it is.
0:18:39 > 0:18:43Can I say for the record, we were told it was just down the track.
0:18:51 > 0:18:55These big ditches here have kind of acted...
0:18:55 > 0:18:58..like natural pit traps.
0:18:59 > 0:19:04And the water inside there seems to have caught a very large lizard.
0:19:04 > 0:19:09So I'll climb down this ladder and see if I can help it escape.
0:19:10 > 0:19:14'I have to be very careful. A trapped lizard will probably bite.
0:19:14 > 0:19:18'And besides, it might not be the only thing down here.'
0:19:18 > 0:19:21Well, he's big, whatever he is.
0:19:21 > 0:19:24- ANIMAL SQUEAKS - Oh!
0:19:27 > 0:19:29Yes!
0:19:31 > 0:19:33Wow!
0:19:34 > 0:19:37It's an absolute beauty!
0:19:40 > 0:19:44Oh, I'm so glad that we managed to get it,
0:19:44 > 0:19:49because already he feels very, very tired to me.
0:19:49 > 0:19:53Pretty soon this glorious lizard - it's called a golden tegu -
0:19:53 > 0:19:56would have become totally exhausted and drowned.
0:19:56 > 0:20:00The tegus are kind of like the South American version of a monitor.
0:20:00 > 0:20:03They move about actively searching for prey,
0:20:03 > 0:20:06using the tongue, which flicks out of this mouth here,
0:20:06 > 0:20:10to pick up scents and smells and help it to home in on its prey,
0:20:10 > 0:20:15which is often things like eggs, small birds, small mammals...
0:20:15 > 0:20:18In fact, they will take almost anything, and unlike most lizards,
0:20:18 > 0:20:22they've got enough energy to be able to run down their prey.
0:20:22 > 0:20:26'But this one looks like he's on his last legs.'
0:20:26 > 0:20:29He's really tired. His eyes are shut and he's hanging almost lifeless
0:20:29 > 0:20:33in my hands, but I'm pretty certain that when he's released,
0:20:33 > 0:20:35he'll move off.
0:20:41 > 0:20:44'And he doesn't take much persuasion.'
0:20:49 > 0:20:51Yes!
0:20:51 > 0:20:52RUSTLING
0:20:52 > 0:20:56You can hear him charging off into the distance.
0:20:56 > 0:20:58Quite often reptiles will do that.
0:20:58 > 0:21:01When they feel they've reached a point of no return,
0:21:01 > 0:21:05they'll feign death, pretend that they're dead, as he was doing there.
0:21:05 > 0:21:08But they've still got plenty of life left in them.
0:21:09 > 0:21:12Deadly 60 team - wildlife saviours.
0:21:12 > 0:21:16'But the tegu didn't really show us his deadly side,
0:21:16 > 0:21:18'so I can't put him on the list.
0:21:18 > 0:21:21'But luckily we soon spot our next candidate.'
0:21:24 > 0:21:27This is a regular wildlife-rescue day!
0:21:31 > 0:21:35Our next little wonder is much, much smaller,
0:21:35 > 0:21:37but in its way,
0:21:37 > 0:21:40even more deadly.
0:21:40 > 0:21:43'This poison dart frog has toxins on its skin
0:21:43 > 0:21:45'that could kill me several times over.
0:21:45 > 0:21:48'But these frogs are already on the Deadly 60,
0:21:48 > 0:21:50'so I'm just going to release him.
0:21:53 > 0:21:56'So, after washing my hands very carefully indeed,
0:21:56 > 0:21:58'it's back on with our snake hunt.
0:21:58 > 0:22:02'We still haven't found our final contender, and time is running out.
0:22:04 > 0:22:08'Unbelievably, only minutes later, we spot the tail of a snake
0:22:08 > 0:22:10'disappearing down a hole.'
0:22:10 > 0:22:13Great stuff! 'Could this be the one?'
0:22:14 > 0:22:17- HE CHUCKLES - I really want to kneel down here,
0:22:17 > 0:22:20but there's loads of nasty stinging ants.
0:22:32 > 0:22:33Wow!
0:22:33 > 0:22:35That...
0:22:35 > 0:22:38is an enormous snake!
0:22:39 > 0:22:42Torch, someone? Torch?
0:22:43 > 0:22:47'This is not what I had in mind, but it's perhaps even better.'
0:22:52 > 0:22:56It just keeps on coming and coming and coming.
0:22:57 > 0:22:59Look at the size of it!
0:23:03 > 0:23:05'This isn't a venomous snake,
0:23:05 > 0:23:09'but it does have one of the most powerful bites of all snakes,
0:23:09 > 0:23:13'with jaws bristling with teeth. I must handle it with extreme care.'
0:23:15 > 0:23:18This...is a yellow-tailed cribo,
0:23:18 > 0:23:22and it is absolutely enormous, by far the biggest one I've ever seen.
0:23:22 > 0:23:27The tail is a glorious golden-yellow colour.
0:23:27 > 0:23:32The scales are so shiny, it's almost like handling a snake made of silk.
0:23:32 > 0:23:35It's almost impossible to keep a hold of him.
0:23:35 > 0:23:38He just keeps shifting through my hands. Look at that!
0:23:38 > 0:23:41You just can't grip him.
0:23:42 > 0:23:45People think of snakes as being slimy creatures,
0:23:45 > 0:23:49but it couldn't be further from the truth. The skin is totally dry,
0:23:49 > 0:23:52and in this animal, it's like silk or crushed velvet.
0:23:53 > 0:23:55Utterly wondrous!
0:23:55 > 0:23:59'And it's this smooth, muscular body that helps the cribo
0:23:59 > 0:24:02'move through the undergrowth and down holes in search of its prey.'
0:24:02 > 0:24:06Now, this is a snake that will feed on all sorts of other things.
0:24:06 > 0:24:10It'll feed on lizards, frogs, birds' eggs,
0:24:10 > 0:24:13and also on other snakes, and a big one like this
0:24:13 > 0:24:17could take on some of the most dangerous, the most venomous snakes
0:24:17 > 0:24:20found in Latin America.
0:24:20 > 0:24:24'Lanceheads, coral snakes, rattlesnakes, bushmasters -
0:24:24 > 0:24:28'the most venomous snakes in the Amazon are all hunted by the cribo.
0:24:28 > 0:24:31'It restrains prey with its bulk and overpowering bite,
0:24:31 > 0:24:35'and swallows it whole and often alive.
0:24:35 > 0:24:39'Cribos will eat huge boas, even hard-shelled tortoises.
0:24:39 > 0:24:42'This cribo can hopefully sense I mean him no harm.
0:24:42 > 0:24:46'With gentle handling, he's showing no signs of biting.'
0:24:46 > 0:24:50Well, I got absolutely covered in ant bites and stings,
0:24:50 > 0:24:52but it is absolutely worth it.
0:24:52 > 0:24:56This is one of the most magnificent snakes found around here,
0:24:56 > 0:25:00and by far the biggest yellow-tailed cribo I've ever seen.
0:25:01 > 0:25:05I reckon this awesome animal that eats other snakes,
0:25:05 > 0:25:09birds, lizards, frogs, anything that is unlucky enough
0:25:09 > 0:25:11to come into its path -
0:25:11 > 0:25:14yellow-tailed cribo is on the Deadly 60.
0:25:18 > 0:25:21The yellow-tailed cribo is a super-sized snake
0:25:21 > 0:25:24with attitude to match.
0:25:25 > 0:25:29And it kills them with one of the most powerful bites of all snakes.
0:25:36 > 0:25:40We were supposed to be filming wildlife out on the lake today,
0:25:40 > 0:25:44but it's just one of those Deadly 60 days where so much happens,
0:25:44 > 0:25:47you just never get a chance to. This has been totally crazy.
0:25:50 > 0:25:53'And it's a fitting end to our Deadly 60 search -
0:25:53 > 0:25:56'for now, at least.
0:25:56 > 0:26:00'So there you have it - another 60 awe-inspiring predators
0:26:00 > 0:26:04'from all corners of Planet Earth.'
0:26:04 > 0:26:05No way!
0:26:05 > 0:26:08'From the tiny spoor spider...'
0:26:09 > 0:26:10Oh!
0:26:10 > 0:26:12'..to the giant Humboldt squid.'
0:26:13 > 0:26:16'From a king cobra...
0:26:17 > 0:26:19'..to King Kong!
0:26:20 > 0:26:23'They come in all shapes,
0:26:23 > 0:26:25'sizes and speeds.'
0:26:27 > 0:26:28Agh!
0:26:29 > 0:26:31- DOG BARKS - Whoa!
0:26:32 > 0:26:35'It's been the expedition of a lifetime.
0:26:36 > 0:26:39'But it hasn't always gone to plan.' Argh!
0:26:40 > 0:26:42Argh!
0:26:42 > 0:26:45'But as ever, we've made the most of it.'
0:26:46 > 0:26:48Wa-hey!
0:26:49 > 0:26:50Wow!
0:26:53 > 0:26:55Crikey!
0:26:59 > 0:27:02'And, do you know what? We're not done yet.
0:27:03 > 0:27:06'Because there are so many more of the planet's predators to find.
0:27:08 > 0:27:12'And as ever, you'll be coming with me every step of the way.'
0:27:17 > 0:27:20What kind of fool would bring a suitcase to the rainforest?
