0:00:02 > 0:00:04My name's Steven Backshall...
0:00:06 > 0:00:08..and this is my search for the Deadly 60.
0:00:10 > 0:00:11Amazing!
0:00:11 > 0:00:14It's not just animals that are deadly to me
0:00:14 > 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 > 0:00:27Argh!
0:00:30 > 0:00:32This time on Deadly 60, we're in the Philippines.
0:00:32 > 0:00:34The Philippines is an archipelago,
0:00:34 > 0:00:37that is a nation made up of thousands of islands.
0:00:37 > 0:00:40And it's absolute paradise for deadly animals.
0:00:40 > 0:00:42The Philippines is located in southeast Asia
0:00:42 > 0:00:44in the western Pacific Ocean.
0:00:46 > 0:00:48It's got a little bit of everything -
0:00:48 > 0:00:53sweaty jungles to paradise coastlands to spangly, clear oceans.
0:00:53 > 0:00:57And every one of these habitats has contenders for my lethal list.
0:00:58 > 0:01:02First up, the crew and I are heading to one of these idyllic islands.
0:01:05 > 0:01:07This place is paradise!
0:01:07 > 0:01:09But these clear waters and white sands
0:01:09 > 0:01:12hide a prehistoric-looking, cold-blooded ninja.
0:01:16 > 0:01:18That animal is a water monitor lizard.
0:01:18 > 0:01:21Close relative of the komodo dragon
0:01:21 > 0:01:24and one of the largest lizards in the world.
0:01:27 > 0:01:30Theses fearsome predators eat anything -
0:01:30 > 0:01:33from birds' eggs on the land to fish in the sea.
0:01:34 > 0:01:37When it comes to tracking down a meal,
0:01:37 > 0:01:38they'll go to extreme lengths,
0:01:38 > 0:01:42with the strength and skills to swim, climb and run.
0:01:46 > 0:01:50It's always difficult to get close to monitor lizards out in the wild
0:01:50 > 0:01:53because they're naturally cautious and frightened of people.
0:01:53 > 0:01:58They are, fantastic opportunists and they'll take any chance that comes.
0:01:58 > 0:02:01So, some monitors have learnt to live with people
0:02:01 > 0:02:02and scavenge off what they leave.
0:02:02 > 0:02:05So, just down here is a picnic area
0:02:05 > 0:02:07where people leave behind scraps.
0:02:07 > 0:02:09I'm hoping there might be some there.
0:02:13 > 0:02:17Everyone keep your eyes peeled and give me a shout if you see anything.
0:02:17 > 0:02:20Water monitors need to be approached with care
0:02:20 > 0:02:23because they are potentially dangerous animals.
0:02:27 > 0:02:28Just there!
0:02:33 > 0:02:35This is a water monitor.
0:02:36 > 0:02:38And he's very bold indeed.
0:02:40 > 0:02:43Nothing is safe from the water monitors on this island.
0:02:43 > 0:02:49They are enormous and adults can grow up to three metres.
0:02:53 > 0:02:57The weapons monitor lizard possesses are SO vicious!
0:02:57 > 0:03:00The tail, which is facing Johnny at the moment,
0:03:00 > 0:03:03is one of the first things it uses in defence.
0:03:03 > 0:03:04It lashes out with that tail
0:03:04 > 0:03:07to drive away anything that could be a potential threat.
0:03:09 > 0:03:13As he's moving through the leaves, tongue's lashing out ahead of him.
0:03:14 > 0:03:18You see it's a forked tongue, just like a snake's.
0:03:18 > 0:03:19And what happens is...
0:03:21 > 0:03:23..each side of that tongue
0:03:23 > 0:03:28is drawing in scent molecules into his mouth.
0:03:30 > 0:03:33And you can tell from which side
0:03:33 > 0:03:36has the stronger taste, the stronger smell,
0:03:36 > 0:03:40which direction to head towards in search of food.
0:03:44 > 0:03:46I'm going to sit very, very still now.
0:03:48 > 0:03:49Nose to nose...
0:03:51 > 0:03:53..with a living dinosaur.
0:03:54 > 0:03:57You can see him lick his lips there.
0:03:57 > 0:04:01I hope that's not because he thinks I might be dinner.
0:04:03 > 0:04:08This is a bit closer than I would really be comfortable with.
0:04:08 > 0:04:14Inside that mouth is one long line of teeth
0:04:14 > 0:04:17that are, honestly, razor-sharp.
0:04:18 > 0:04:23Backwards-curving and covered with...
0:04:25 > 0:04:27He's tasting my face!
0:04:27 > 0:04:29He just stuck his tongue in my eye!
0:04:33 > 0:04:36OK, this is where I start to get a little bit nervous.
0:04:38 > 0:04:39He can move very, very fast.
0:04:39 > 0:04:42From there, he could have my arm in his mouth in a second.
0:04:44 > 0:04:46Look at him tasting my hand!
0:04:50 > 0:04:55As I was saying, the mouth has razor-sharp teeth
0:04:55 > 0:04:58which are covered in bacteria.
0:04:58 > 0:05:01And those bacteria, once they actually get into a wound,
0:05:01 > 0:05:06once he cuts you open, will almost instantly start to become infected.
0:05:06 > 0:05:11Any bite from a monitor lizard is very, very serious indeed.
0:05:18 > 0:05:21Wow! He is utterly, utterly beautiful.
0:05:22 > 0:05:23There's another one!
0:05:23 > 0:05:26There's another one coming in from the side over there.
0:05:30 > 0:05:32It's almost like I've been transformed back
0:05:32 > 0:05:35into The Land That Time Forgot, surrounded by dinosaurs.
0:05:35 > 0:05:37'They may look prehistoric,
0:05:37 > 0:05:40'but there's nothing outdated about them.
0:05:40 > 0:05:43'I want to show you how adaptable they are when it comes to hunting.'
0:05:44 > 0:05:48There are monitors absolutely everywhere.
0:05:48 > 0:05:51There must be seven or eight of them, all of them good-sized,
0:05:51 > 0:05:54within about 10-15m of us, off in these trees.
0:05:54 > 0:05:56I'll see if I can show you some of their tricks
0:05:56 > 0:06:00using a yummy bit of fish head.
0:06:01 > 0:06:05'The first attribute I want to show you is their climbing ability.'
0:06:08 > 0:06:09OK.
0:06:09 > 0:06:11So that's our fish in place.
0:06:11 > 0:06:15Let's see if our monitor will follow it up the tree.
0:06:15 > 0:06:16OK.
0:06:23 > 0:06:24Look at that!
0:06:24 > 0:06:27They're like an all-terrain vehicle,
0:06:27 > 0:06:31just scampering up the tree in search of food.
0:06:33 > 0:06:34Yes!
0:06:34 > 0:06:35And he's got it.
0:06:37 > 0:06:42He may be a top-notch climber but he lands like a dropped pudding.
0:06:42 > 0:06:45Ha! That is awe-inspiring!
0:06:45 > 0:06:47There he goes again.
0:06:50 > 0:06:52Even at this size,
0:06:52 > 0:06:55he has no problem holding his body weight
0:06:55 > 0:06:57on a tree using those big, curved talons.
0:06:59 > 0:07:01Wow!
0:07:05 > 0:07:07OK, we've shown you them climbing and feeding.
0:07:07 > 0:07:09The last thing that I want to try and show you,
0:07:09 > 0:07:11this is a real long shot,
0:07:11 > 0:07:13is one of these guys actually swimming in the sea.
0:07:13 > 0:07:16Let's see if I can draw one down to the beach.
0:07:21 > 0:07:22They've got interest.
0:07:22 > 0:07:26Yes, I am actually taking a monitor for a walk.
0:07:26 > 0:07:28Well, a run, actually.
0:07:29 > 0:07:30We're going to the beach!
0:07:33 > 0:07:36Unlike most reptiles that can only run in short bursts,
0:07:36 > 0:07:39monitors can keep their foot on the gas
0:07:39 > 0:07:41and actually run down their prey.
0:07:50 > 0:07:51# Most of all
0:07:52 > 0:07:55# I like the way you move... #
0:07:59 > 0:08:00There he goes.
0:08:03 > 0:08:07That is why he's called a water monitor lizard.
0:08:07 > 0:08:10Look at that - swimming using that broad tail,
0:08:10 > 0:08:15making him move through the water beautifully.
0:08:15 > 0:08:19And even underwater, the tongue is still flicking out.
0:08:19 > 0:08:21He can still taste even there.
0:08:22 > 0:08:27The water monitor - sprinting, swimming, climbing, clambering -
0:08:27 > 0:08:30the ultimate predator on the Deadly 60.
0:08:44 > 0:08:46Water monitor lizards - deadly!
0:08:51 > 0:08:53I'm really excited about our next destination.
0:08:53 > 0:08:56We're heading in there.
0:08:56 > 0:08:58I have no real idea what live inside that cave
0:08:58 > 0:09:00but I'm very excited to find out.
0:09:05 > 0:09:07'We're exploring this cave system
0:09:07 > 0:09:09'on the mysterious river that runs through it,
0:09:09 > 0:09:12'paddling into the gloom.'
0:09:14 > 0:09:17This is seriously spooky, heading into the darkness.
0:09:32 > 0:09:34From here on in, the river flows into total darkness.
0:09:35 > 0:09:39Beyond here has never, ever seen sunlight.
0:09:40 > 0:09:43So, in order to see the animals that are living here
0:09:43 > 0:09:46we're relying on torchlight.
0:09:48 > 0:09:50The animals that survive in caves
0:09:50 > 0:09:53are highly adapted to the environment and, as a consequence,
0:09:53 > 0:09:56they tend to look very bizarre.
0:10:00 > 0:10:01One group of mammals
0:10:01 > 0:10:05that may spend much of their lives in caves are bats.
0:10:07 > 0:10:10This place is absolutely alive with bats...
0:10:11 > 0:10:16..all hanging from the ceiling, usually just by one tiny toe.
0:10:22 > 0:10:25But I want to find something even more creepy.
0:10:28 > 0:10:31I'm going to try and go ashore and see if I can see anything.
0:10:33 > 0:10:34OK.
0:10:37 > 0:10:39Cave crickets...
0:10:40 > 0:10:41..everywhere.
0:10:42 > 0:10:47These crickets are the favourite food of some horrible cave hunters.
0:10:49 > 0:10:55This cave floor is absolutely alive with tarantulas.
0:10:55 > 0:10:57I've never seen so many in my entire life.
0:10:58 > 0:11:01It's an arachnophobic's nightmare.
0:11:02 > 0:11:03Where's he gone?
0:11:07 > 0:11:08Oh, no!
0:11:10 > 0:11:11He's gone into a little hole.
0:11:14 > 0:11:17There he goes, out into the open.
0:11:17 > 0:11:18There he is.
0:11:25 > 0:11:27Go on, there you go.
0:11:27 > 0:11:31Just backing up... Oh! He's just struck the stick.
0:11:32 > 0:11:34It means it bit it with its fangs.
0:11:34 > 0:11:37And he's just...
0:11:37 > 0:11:39Oh! And again!
0:11:39 > 0:11:41That was quite an aggressive strike.
0:11:41 > 0:11:45If that had been my hand, that would have really hurt.
0:11:47 > 0:11:48Cor!
0:11:48 > 0:11:50'Well, that one got away, but...'
0:11:50 > 0:11:54It doesn't matter, though, there are loads of them around here.
0:11:56 > 0:11:58Oh, dear me!
0:11:59 > 0:12:02Eugh! Cor, they're quick.
0:12:04 > 0:12:06HE CHUCKLES
0:12:06 > 0:12:10It might look like I'm being a right jessie,
0:12:10 > 0:12:15but it wouldn't be ideal to get bitten right deep here in the cave.
0:12:16 > 0:12:18Oh, crikey! Ah!
0:12:19 > 0:12:22Just not having any luck today.
0:12:26 > 0:12:27There he goes.
0:12:27 > 0:12:29Got him.
0:12:29 > 0:12:32More by accident than by design, it has to be said.
0:12:32 > 0:12:35This is actually one of the smallest of the tarantulas
0:12:35 > 0:12:38that we've seen scurrying around here,
0:12:38 > 0:12:41but I couldn't leave without getting a closer look at him.
0:12:41 > 0:12:46I mean, I think I must have seen 30 in this one tiny area.
0:12:46 > 0:12:50'It's hardly surprising when you see how many crickets are around,
0:12:50 > 0:12:54'but what I really want to show you is how they hunt in the dark.'
0:12:54 > 0:12:58The legs and the back of the body
0:12:58 > 0:13:01are all covered with thousands of fine hairs
0:13:01 > 0:13:04and those hairs are really sensitive.
0:13:04 > 0:13:07They can pick up everything from chemical scents in the air
0:13:07 > 0:13:10to the movement of the air to vibrations along the ground.
0:13:10 > 0:13:14They're a great way for this spider to find out what's going on
0:13:14 > 0:13:16and also what it needs to hunt.
0:13:16 > 0:13:20OK, let me just show you how those hairs work.
0:13:26 > 0:13:27Any second now.
0:13:30 > 0:13:34Well, it normally works. It's just obviously not working today.
0:13:34 > 0:13:38Normally, he'd run off, but I think he likes me.
0:13:42 > 0:13:43Oooh! Ha-ha!
0:13:43 > 0:13:48OK, I wasn't intending him to run down the back of my neck!
0:13:50 > 0:13:53But that shows you how the hairs work.
0:13:55 > 0:13:59'The tarantula is a superb spider assassin,
0:13:59 > 0:14:04'but with so many crickets around, there is a chance
0:14:04 > 0:14:06'we might find the ultimate cave predator.'
0:14:09 > 0:14:12One of the most specialised cave-hunting creatures
0:14:12 > 0:14:15you'll see anywhere in the world is this...
0:14:16 > 0:14:18..the whip-spider.
0:14:20 > 0:14:22Look at that.
0:14:22 > 0:14:26Really creepy looking monsters, aren't they?
0:14:28 > 0:14:33One of the most lethal hunters you'll ever see in a cave system.
0:14:33 > 0:14:36Look at those front legs swinging around in the air -
0:14:36 > 0:14:42just tapping around, sensing its environment,
0:14:42 > 0:14:45building up a picture of what's around it.
0:14:47 > 0:14:51The whip-spider is also called a tail-less whip scorpion.
0:14:51 > 0:14:54It's actually not a spider or a scorpion,
0:14:54 > 0:14:56but it's still a member of the arachnid group.
0:14:56 > 0:14:59The front legs of the whip-spider are not used for walking,
0:14:59 > 0:15:02but are adapted to sensing its surroundings.
0:15:02 > 0:15:06These bizarre legs can be three times longer than the other legs.
0:15:06 > 0:15:09But the main weapons are those claws
0:15:09 > 0:15:13it's got clasped to the front of its head.
0:15:13 > 0:15:16They're armed with vicious barbs
0:15:16 > 0:15:19and when it gets close to an insect,
0:15:19 > 0:15:22those open out, grab a hold of it,
0:15:22 > 0:15:27draw it in to its mashing mouth parts it has here at the front.
0:15:27 > 0:15:29The whip-spider feeds
0:15:29 > 0:15:32by using those trap-like pincers to snare an insect
0:15:32 > 0:15:36and munching mouth parts to chew it up into goo.
0:15:38 > 0:15:39Eugh!
0:15:39 > 0:15:44The whip-spider is one of the most perfectly adapted creatures
0:15:44 > 0:15:47you'll ever see for cave environments -
0:15:47 > 0:15:51perfectly adapted to life hunting in the dark.
0:15:51 > 0:15:54'Whip-spider is on the Deadly 60.'
0:16:15 > 0:16:19'No sooner had we paddled out of the cave into open air,
0:16:19 > 0:16:23'then the sun set and it was dark again!'
0:16:23 > 0:16:27These forests are very exciting for wildlife during the day,
0:16:27 > 0:16:30but at night-time, they get even better,
0:16:30 > 0:16:32and this time, shortly after dusk,
0:16:32 > 0:16:34is almost like rush hour for wildlife.
0:16:34 > 0:16:38It's just the time when everything is waking up
0:16:38 > 0:16:40and thinking about going out and finding food.
0:16:40 > 0:16:43There's one particular deadly animal
0:16:43 > 0:16:45that I'm, well, really hoping we'll find.
0:16:46 > 0:16:51The animal we're searching for is a pangolin.
0:16:51 > 0:16:54Pangolins are found all over Africa and Asia.
0:16:54 > 0:16:58This crazy-looking, armoured critter might look small,
0:16:58 > 0:17:01but it has unimaginable strength for its size.
0:17:01 > 0:17:04Pangolins are ant and termite terminators
0:17:04 > 0:17:06and have the ideal tools for devouring them.
0:17:06 > 0:17:10Their strength and sharp claws mean they easily rip open termite mounds
0:17:10 > 0:17:13and they have a tongue longer than their own body.
0:17:13 > 0:17:17One pangolin can eat more than 70 million termites in one year.
0:17:18 > 0:17:22OK, so this is a termite mound.
0:17:22 > 0:17:25The termites create it using chewed-up mud
0:17:25 > 0:17:29and their own saliva and it sets rock hard.
0:17:29 > 0:17:32I'm going to have a go at trying to get into this.
0:17:32 > 0:17:36This is the kind of thing that the pangolin will break into with ease.
0:17:36 > 0:17:39I've got my metal snake hook here. Let's see how I do.
0:17:44 > 0:17:48This thing is like an absolute fortress.
0:17:53 > 0:17:57I'll be here all night before I get to any termites,
0:17:57 > 0:18:02and that is using a metal, human-made snake hook,
0:18:02 > 0:18:05but our pangolin scrapes it open in a matter of minutes.
0:18:05 > 0:18:08That's awesome!
0:18:08 > 0:18:10'At night, the pangolins are hunting,
0:18:10 > 0:18:13'so this is the best chance we have to see them.'
0:18:13 > 0:18:18Normally, wildlife watching at night is about moving carefully, slowly,
0:18:18 > 0:18:21but at the moment, we're thundering through the undergrowth,
0:18:21 > 0:18:24because the guy in front of me, who's our guide,
0:18:24 > 0:18:27has just had a shout from one of his friends
0:18:27 > 0:18:30that the exact animal we're looking for is somewhere off
0:18:30 > 0:18:32in this undergrowth here.
0:18:32 > 0:18:35We're doing our best to try and keep up with it.
0:18:49 > 0:18:51Oh, wow! There it is.
0:18:55 > 0:18:57Wow!
0:18:59 > 0:19:03This is a pangolin.
0:19:03 > 0:19:08It's a very unusual creature indeed.
0:19:08 > 0:19:11At the moment, it's gone into its defensive position,
0:19:11 > 0:19:16which is designed to protect its soft underbelly,
0:19:16 > 0:19:19using these tough scales on the outside.
0:19:21 > 0:19:26The thick tail of the pangolin is wrapped right around the head,
0:19:27 > 0:19:30which is protected by all of this armour.
0:19:30 > 0:19:33The armour also works to protect it from its prey.
0:19:33 > 0:19:38It feeds on ants and termites which have vicious bites and stings,
0:19:38 > 0:19:42and all of this armour helps protect it from them.
0:19:42 > 0:19:44At the moment, obviously he's quite concerned
0:19:44 > 0:19:47that we might be a predator about to tuck into him,
0:19:47 > 0:19:50so what we need to do is to back off, give him some space,
0:19:50 > 0:19:54and give him some time and, hopefully, he'll unfurl
0:19:54 > 0:19:56and wander off in search of a meal
0:19:56 > 0:20:00and then we'll see why this is such an astounding creature.
0:20:08 > 0:20:11So we're just going to sit still here for a while
0:20:11 > 0:20:14and just listen, see if we can hear him unfurling.
0:20:24 > 0:20:25RUSTLING
0:20:25 > 0:20:27Sounds like he's getting up.
0:20:35 > 0:20:37He's just unfurled
0:20:37 > 0:20:43and looks like he's sussing out what's going on around him
0:20:43 > 0:20:45before he moves on.
0:20:45 > 0:20:51I've got to say that is a seriously crazy-looking creature.
0:20:57 > 0:21:00The pangolin's primary sense is their smell.
0:21:00 > 0:21:05They can scent ants and termites from hundreds of metres away
0:21:05 > 0:21:08and now, I think, he's just sussing out
0:21:08 > 0:21:10what's going on with me and the camera crew,
0:21:10 > 0:21:14just raising his nose, snuffling the air,
0:21:14 > 0:21:16just figuring out what we are.
0:21:17 > 0:21:22Just see now him lifting his front leg -
0:21:22 > 0:21:25those curved claws are what he'll use
0:21:25 > 0:21:30to tear his way into termite mounds and ant hills.
0:21:30 > 0:21:33He can dig through ground that is almost as hard as concrete
0:21:33 > 0:21:34using those.
0:21:37 > 0:21:41Ooh, it looks like he's going to climb. He's going up the tree.
0:21:41 > 0:21:44Pangolins are fantastic climbers
0:21:44 > 0:21:48and it's another way they have of escaping danger
0:21:48 > 0:21:52and also of going looking for ants in the treetops.
0:21:52 > 0:21:56Look how he clasps the tree with his claws as he climbs!
0:21:58 > 0:22:01He shot up there.
0:22:03 > 0:22:05Clasp them that tightly,
0:22:05 > 0:22:09no predator's going to be able to drag him off.
0:22:09 > 0:22:10The pangolin -
0:22:10 > 0:22:16the fast-climbing, ant-lapping, excavating, armour-plated machine
0:22:16 > 0:22:18has got to go on the Deadly 60.
0:22:41 > 0:22:45The Philippines are well known got their tropical mangrove forests
0:22:45 > 0:22:47that connect the land to the sea
0:22:47 > 0:22:51and are home to a whole host of unusual and colourful animals.
0:22:51 > 0:22:55Mangrove trees are unique in that they are the only trees
0:22:55 > 0:22:58that can survive in the salty seawater.
0:22:58 > 0:23:02They're the perfect cover for more dazzling animals
0:23:02 > 0:23:05and I have one in mind, but it'll take some finding.
0:23:14 > 0:23:17The mangroves are very much slave to the tides.
0:23:17 > 0:23:20When it's high tide and the water's in like now,
0:23:20 > 0:23:23the best way of getting around is in a boat.
0:23:23 > 0:23:27You don't have to slog through all the mud and can cover more distance.
0:23:27 > 0:23:28Let's see what we can find.
0:23:28 > 0:23:33'After a full day of scanning the foliage,
0:23:33 > 0:23:34'we found our prize.
0:23:34 > 0:23:40'My stunning snake is hanging out way up in the branches.
0:23:42 > 0:23:44'But how am I going to get it down?
0:23:44 > 0:23:47'It's going to take a little nerve to show him to you.'
0:23:47 > 0:23:51I'm just going to get up there and see if I can grab it.
0:24:15 > 0:24:20The problem is, I just need one more hand.
0:24:32 > 0:24:35Come on then, little fella. Oh-h!
0:24:41 > 0:24:43OK.
0:25:11 > 0:25:16Well, that was one of the hardest snake catches I've ever had,
0:25:16 > 0:25:23but it was well worth it, cos this is the master of the mangroves -
0:25:23 > 0:25:25the mangrove cat snake.
0:25:25 > 0:25:29The reason this is called a cat snake is the eyes.
0:25:29 > 0:25:33It's a dark eye with a slit-shaped pupil,
0:25:33 > 0:25:34very much like a cat's eye.
0:25:36 > 0:25:38It is utterly, utterly gorgeous -
0:25:38 > 0:25:41I think one of the prettiest snakes on the planet.
0:25:41 > 0:25:43Look at those bright, bright lurid colours -
0:25:43 > 0:25:45black against bright, bright yellow.
0:25:45 > 0:25:48It seems crazy that a snake like this could be camouflaged
0:25:48 > 0:25:51in this environment,
0:25:51 > 0:25:53but if Johnny gets a shot of these palms here -
0:25:53 > 0:25:56as the light comes down through those,
0:25:56 > 0:25:59you get black slats of shadow
0:25:59 > 0:26:03in-between yellow slats of these, illuminated by the sun,
0:26:03 > 0:26:07and actually, this snake blends in beautifully.
0:26:07 > 0:26:10You can see, wrapped around my arm there,
0:26:10 > 0:26:13and as it was up in the tree, curled around that branch,
0:26:13 > 0:26:17that this snake is absolutely brilliant at holding itself
0:26:17 > 0:26:19in the trees and the branches and the twigs.
0:26:19 > 0:26:21That's where it does its hunting.
0:26:21 > 0:26:24They'll feed on small birds and lizards.
0:26:24 > 0:26:28All kinds of wonderful creatures are at the mercy
0:26:28 > 0:26:29of this awesome little snake.
0:26:29 > 0:26:33The venom of the mangrove cat snake isn't particularly strong.
0:26:33 > 0:26:35It's not harmful to humans,
0:26:35 > 0:26:38but it does work very, very fast on its prey.
0:26:38 > 0:26:41The mangrove cat snake is not only pretty much
0:26:41 > 0:26:44my favourite snake in the whole world,
0:26:44 > 0:26:48but it is also the most colourful killer of the mangroves.
0:26:48 > 0:26:50It can climb and it can also swim.
0:26:50 > 0:26:53I have to put the mangrove cat snake onto the Deadly 60.
0:27:16 > 0:27:19Next time on Deadly 60.
0:27:25 > 0:27:27They rock.
