00:06the stories you're about to see are real terrifying home invasions and tyrants
00:18fighting to end all competition these clashers and crashers ignore boundaries
00:24and battle to the death we're counting down the 10 most intense deadly duels on weird true and freaky
00:40two bitter rivals face off and these odds could equal some sweet revenge
00:50serengeti tanzania here east africa's watering holes are a vital resource for some of the
00:57world's largest animals but they're also a dangerous hunting ground for a prehistoric
01:04predator the nile crocodile now crocodiles are ferocious predators they can reach up to 20 feet
01:111600 pounds they attack their prey by using the element of surprise they grab the prey drag it
01:19underwater and dismember it or drown it near the banks of a river a nile croc slowly makes its way
01:27through the water hunting a meal but as it stealthily swims under the surface it makes a big mistake
01:35this croc's not alone it's entered the territory of 30 adult hippos the croc does its best to keep
01:46hidden but when a hippo senses its presence underwater all hell breaks loose
01:56the reptile thrashes trying desperately to flee but it's trapped and outnumbered
02:04they are going for us to get out of our space getting out of this mess will be nearly impossible
02:13hippos might be herbivores but they're extremely dangerous they're so aggressive the crocodiles
02:19usually stay away but when the rain stop the water starts to dry up and hippos and crocs compete for
02:26the same space and that's when things get really violent suddenly the croc slips under and the action
02:34stops unseen and submerged this may be its only chance there he is but then
02:45got it when the croc comes back up for air the hippos spot the predator and attack clamping down
02:53one of the hippos lifts the croc up out of the water it tears into the reptile's tough exterior
03:01got him big time hippos canine teeth are over a foot long each they can snap a canoe in half
03:08with just
03:09one chunk the crocodile's skin is like armor plating but that's no match for a hippo
03:17but a last-ditch move changes everything the croc manages to bite one of the massive behemoths
03:25creating a commotion and a chance to escape wriggling free it slips under the water again
03:34out of the jaws of death it's a missed opportunity for the hippos but they've shown this croc who's boss
03:42in this watering hole next in our deadly dual countdown is number nine sending the wrong signals
03:55could get you into deep trouble
04:01st mark's river florida each morning fishermen head to these waters to haul in a catch
04:08fish and commune with local wildlife including often ill-tempered geese these are large migratory
04:16waterfowl that live on rivers lakes and ponds they eat mostly vegetation and insects but they also eat
04:23small fish on a day like any other pro angler drew Gregory's out on the river with fellow fishermen
04:31catching lines and reeling in plenty of fish recording everything on a camera connected to
04:38his kayak drew decides to throw one of his smaller catches to a hungry river resident nearby
04:47for drew it's a kind gesture but the goose doesn't see it that way little does drew know he's just
04:55issued a challenge geese are very territorial and can be extremely aggressive even if offered food
05:02they might not take it as a gracious gesture they kept moving closer and closer to me and the big
05:09one
05:09starts getting very brave and it starts investigating around my kayak and nipping at my fishing lures I'm
05:14like hey man stay away I want to catch fish not geese suddenly the goose attacks I feel these legs
05:26and
05:26wings and limbs all over my back just jumping on me like crazy and I had no clue what it
05:30was or what
05:31was happening even though geese only weigh about 10 pounds they have very strong solid wings and if
05:37they want to jump and attack they will use those wings to beat against whatever it is including a
05:42predator or a human that just might be in the wrong place at the wrong time then the goose knots
05:51drew
05:51off balance toppling him over straight into gator territory and fighting his way back to the edge of
06:02his kayak drew realizes he can't get back in gooses squawking and honking and just going nuts
06:12and I'm just gagging trying to catch my breath I started thinking I know the gators typically
06:17don't bother you but I'm sitting here flailing this could be a much worse incident here today
06:24this type of commotion often attracts alligators because they think it's prey struggling so he needs
06:30to get out of that water immediately just when all seems lost one of Drew's fishing buddies paddles
06:38over in the nick of time and helps him upright to safety that wasn't hurt from the incident other
06:46than you know my ego so we kept fishing and we floated our way down the river for the rest
06:50of that
06:50day and we said we've got to share this to the world
06:58before we get to the next story in our deadly dual countdown when you enter the ring with this
07:05miniature scrapper you'd better come prepared or else
07:17this busy city is a center for medicine science and education but not all the city's residents are
07:26here to learn like most crowded urban areas rodents are a constant problem rats congregate in urban
07:35environments because urban environments provide everything rats love lots of food debris water
07:43shelter so being in a dense urban environment provides the perfect environment for them to
07:50get everything they need and also have quick getaways on a quiet morning 20 year old student to we side
08:00is sweeping debris from a hole near her apartment when a giant road suddenly enters the pit and goes on
08:08the
08:08attack trapped and afraid the young student swats again and again but the rat dodges each time then he
08:21tries a new tactic an aerial assault bearing his teeth the rodent flies through the air jumping with
08:32shocking strength for such a small pest rats can jump about two and a half feet up in the air
08:40and they
08:41can jump outward about four feet so that's pretty good they have some powerful back legs and they can
08:47also run fairly fast but this rat is just as afraid of the woman as she is of him he
08:56suddenly runs toward a
08:58corner of the pit looking for a way out in this momentary ceasefire an onlooker extends his hand down to
09:09the
09:09woman it's a chance to escape
09:14that goes horribly wrong
09:20now two people are stuck in the pit with the unstoppable rat
09:27the man quickly hoists himself to safety leaving the rat in hot pursuit of the terrified woman
09:33alone helpless and cornered by the charging vermin a filthy rodent bite seems inevitable they are carrying
09:42diseases that they can give to humans which are zoonotic diseases and they do carry some pretty
09:49significant zoonotic diseases that humans can catch some of those are things like plague hantavirus
09:59tularemia rat fight fever
10:07fortunately the somewhat comical encounter ends without injury later twee's able to laugh it off but
10:15hopefully next time she'll remember never bring a broom to a fight with this feisty rat
10:26next in our deadly duel countdown is number eight
10:32with this home invader roaming the neighborhood you should always watch your back
10:41Colorado springs Colorado sitting at the base of the rocky mountains this vibrant town overlaps with wild
10:50nature and anywhere the two worlds intersect there's the potential for encounters with a variety of
10:57animals from white-tailed deer to opportunistic black bears black bears are mostly scavengers they
11:07fully have the capability of hunting and chasing down animals for food but that takes a lot of
11:12effort in urban areas they're gonna eat whatever is easiest to come upon most likely your garbage or
11:19whatever dog food or cat food gets left outside
11:23up in the hills above town danielle backstrom arrives home and pulls into her garage
11:31and just when she's about to exit her vehicle she discovers she's not alone
11:41in a state where over 17 000 black bears roam one of the hungry predators has slipped in when she
11:48wasn't
11:48looking and now he doesn't seem like he's going to leave he's on the hunt for an easy meal and
11:56it's a
11:57dangerous trend when bears start associating us with food there's almost no going back habituation is when a wild
12:06animal gets used to humans being around and a wild animal that's not afraid of people is way more
12:12dangerous than a wild animal that is they're going to go to the wrong person at the wrong time and
12:17either the bear is going to get killed or the person is shoot bear shoot the situation is getting serious
12:27if the bear doesn't want to leave there's very little danielle can do um i can't go because
12:33there is a bear behind me come on bear move putting her car in reverse she tries to nudge the
12:39bear
12:40slowly out but he only moves side to side not away oh my god trapped and afraid danielle has no
12:51way out
12:54normally if you encounter a black bear in the wild you want to be very loud and be as big
12:59as you can
13:01in this situation this woman is trapped in her car and is of no threat to the bear at all
13:06it's not
13:07afraid of humans because at this point it's probably learned they don't do anything to it bear
13:13here he is in the ring of your mirror then she gets an idea pulling her car forward let me
13:19see if i
13:20close it if he'll she quickly hits the button to close her garage there he goes he's walking away
13:28successfully locking the bear out shutting the door on this furry intruder
13:37we return to our deadly deer countdown with number seven
13:42golf is tough enough without this dangerous hazard
13:49palmetto florida this coastal town on the gulf of mexico has a subtropical climate perfectly suited
13:57for an array of reptiles but the biggest and possibly the meanest is the american alligator and they
14:06don't always stay in the swamp in florida we have this interesting situation where we get alligators
14:12overlapping with humans a lot and it's because humans are continually sort of claiming this habitat
14:18that these alligators live in and these alligators are not shy
14:22that's why at a local golf course a foursome halts their game when a mammoth alligator slowly saunters
14:29across the fairway that is the biggest freaking alligator i've ever seen in my life
14:39it must be 15 feet long this gator nicknamed chubs for obvious reasons has become a celebrity here
14:52at the course moving between ponds on the third eighth and 14th holes he's definitely chosen this
15:00as his hunting ground you gotta be kidding me the average size for a male is around 11 feet this
15:08one
15:08is obviously way bigger than that it's huge so if this guy has claimed this golf course as its territory
15:13that's a big problem and people would definitely want to steer clear of that guy american alligators
15:20max out at about 15 feet long and 1 000 pounds making chubs potentially as big as they come
15:30what he hunts at a golf course that could feed his incredible size isn't clear a golfer seems like
15:37a normal meal for this behemoth dude watch out man then one of the men makes a bold move
15:47to capture a better shot of the massive beast he walks closer what are you doing
15:54a predator this large is definitely best observed from far away most of the time they look like
16:02they're sort of these lumbering animals that are moving kind of slow i think people can get the wrong
16:07idea they can be really dangerous up close they can move extremely rapidly
16:14thankfully the huge animal isn't interested in a savory snack at the moment
16:20in fact according to golf course staff this alligator and others have been living peacefully in their ponds for
16:28for a long time still if your ball ever lands near a water hazard at this course you should consider
16:36it
16:36lost that is a monster our countdown will continue in a moment but first
16:45in this duel of three against one fortune may not be enough to save this brave bird
16:57zhuzhang province china here the hangzhou safari park is known for exotic animals
17:04like giant pandas golden monkeys and white rhinoceros but today tourists witness and especially rare sighting
17:15wild red crown cranes soaring high in a strong crosswind red crown cranes are one of the largest crane
17:24species they can stand up to five feet tall and have as much as an eight foot wingspan which is
17:30pretty
17:30large it does take them a little bit of effort to get off the ground because of their
17:34large size they need to be able to get somewhat of a running start
17:40then disaster
17:43blown by the wind one of the cranes has come down right in the middle of one of the park's
17:48deadliest enclosures the siberian tigers three in total
17:55with no room to run and take off the crane is forced to confront the deadly predators
18:02he charges the big cats in an unbelievable display of courage and desperation but this bluffing
18:10strategy will only work for so long one swat from an enormous siberian tiger and the beautiful bird will
18:18be dead when red crown cranes are frightened they usually go into a defensive posture they're going to
18:25try to bluff or scare the predator away they'll spread out their eight foot wingspan to look twice as large
18:31as they actually are
18:35after a few false charges from the crane the tigers turn the tables charging back at the bird
18:43instinctually the crane runs a dangerous trigger for a deadly big cat instinct because the tigers have a
18:51strong predatory chase instinct as soon as the bird does turn around the tigers go right after it
18:58then out of nowhere the tigers retreat distracted by a gift of food from the zoo keepers the park
19:06visitors breathe a sigh of relief as the majestic bird is ushered out of the enclosure it turns out
19:13fortune really does favor the brave
19:20our deadly dual countdown continues with number six
19:25in this dysfunctional family just being born can get you killed
19:34atasha national park namibia
19:38these planes bear witness to nature's most ancient balancing act between hunter and hunted
19:45but thinning the herd isn't always a battle of predator versus prey sometimes a new alpha trying to take
19:53over is the biggest threat even one is seemingly noble as the striped zebra in the wild zebras exist as
20:01harems which consist of one dominant male a number of females and their offspring fights among zebra males
20:08can be brutal and very violent they are fighting for access to mates so everything is at stake
20:16on safari a group of tourists stumbles upon a terrifying scene an adult male zebra has pinned a young colt
20:25under water the youngster's mother stands by completely helpless it's almost impossible for her to
20:33overpower the male one-on-one the mother can't watch her baby die
20:44she charges the large male creating a brief opening for the colt to escape
20:51but the stallion refuses to relent and sends a wicked kick in the direction of the mother
20:58when a new male takes over a harem he will systematically kill all of the babies that females
21:04are still nursing this allows the females to come back into estrus so they're sexually receptive
21:09and the male can then father offspring of his own
21:13the male- permet的话
21:15this stepfather from hell bites and kicks at the youngster but the fool manages to slip out
21:21dominique
21:23with help from ma he runs for his life
21:26but the chase doesn't last long
21:29fallen with its undercarriage exposed one blow from the stallions hooves will end this fool's life
21:39Zebra stallions are very aggressive, they can weigh up to 800 pounds, and a single kick can break a lion's
21:46jaw in two.
21:47So even big cats avoid stallion zebras.
21:53But then, the young zebra's mother makes a last-ditch effort to save her child.
22:01The female rams, and rams again, creating just enough distance for the colt to slip away.
22:08For now, it's an incredible example of a desperate mother's unbeatable drive to nurture and defend, no matter the odds.
22:22Before we continue our countdown, maternal instinct is put to the ultimate test.
22:28Can mother's milk feed a mortal enemy?
22:35Russia.
22:36In the far east of the country, in centuries past, the cold, desolate plains were a battleground for two expert
22:45predators, wolves and Siberian tigers.
22:50These two were never meant to play nice.
22:54Dogs were domesticated about 15,000 years ago, and cats were domesticated about 9,000 or 10,000 years ago.
23:02And what we've done is we've sort of forced dogs and cats to live together.
23:05So that's why sometimes our dogs and cats don't get along so well.
23:11But here, in an ordinary Russian home, a bizarre situation unfolds.
23:17A newborn Cornish Rex cat named Eli sucks milk from what seems to be her mother's teeth.
23:28But look again, that's not her mother.
23:32This curly-haired wet nurse is a poodle named Barsik.
23:41While some dogs tolerate and even seem to befriend cats, feeding a kitten their own milk is another story.
23:49A story you have to see to believe.
23:52When a mammal is nursing her young, a hormone called oxytocin is released.
23:58That hormone is known as the happy hormone.
24:01So one could infer that it would be enjoyable for this mammal to be nursing her young.
24:09This abnormal cross-species rearing could have deadly consequences.
24:14If this little kitten bites too hard onto Barsik's teat, instinct could take over.
24:22But the power of a mother's instinct to nurture, even nurse a foe, is more powerful than any rivalry.
24:29The kitten keeps on feeding, and Barsik the poodle seems perfectly at peace,
24:35showing above all, love truly knows no boundaries.
24:42Hold on, hold on.
24:44We return to our deadly dual countdown with number five.
24:49A river overrun turns a casual day of boating into a fierce battle.
24:55Oh my God!
24:59Terre Haute, Indiana.
25:01A town nestled next to the Wabash River.
25:04This 500-mile waterway is a lifeline to dozens of fish species,
25:09including crappie, catfish,
25:12and the notorious and destructive silver carp.
25:16Brought over from Asia in 1973, they've been causing havoc ever since.
25:23They were introduced in America as a way to help deal with algae problems in municipal waterways,
25:29and now they're a real problem in streams and rivers around the country.
25:32They're pushing out the species that are supposed to be in that area.
25:35They're out-competing them.
25:37On a casual day trip, a group of locals get way more than they bargained for.
25:43Oh, man, what the hell?
25:46While parked along the edge of the river,
25:48all around them, silver carp are leaping out of the water and landing in their boat.
25:56Silver carp are sometimes called the flying carp
25:58because they can jump really high, up to 10 feet out of the water.
26:01And they're doing that to evade predators.
26:03They'll jump en masse.
26:04If there's schools of them, they'll all start jumping.
26:08Oh, there they go again!
26:10Then, things get out of hand.
26:13He's so .
26:14The water erupts.
26:17More carves start launching.
26:18Oh, man.
26:19Each one weighs more than a bowling ball, up to 40 pounds.
26:24It's a brutal barrage.
26:27Oh, man, what the hell?
26:30Worried they're in too deep.
26:32Oh, no!
26:33The boaters start the motor and hit the gas.
26:37Oh, man!
26:39Speeding away, the noise and vibrations of the motor
26:42cause even more fish to jump.
26:48And as more fish lift off,
26:50the odds of getting seriously injured by a flying fish increase exponentially.
26:56You're moving very fast.
26:58The fish leaps up.
26:59You hit the fish.
27:00You're going to get injured.
27:01There have been documented cases of people being injured.
27:03I think a boy broke his jaw.
27:05Anything that's in the air,
27:06if you're moving 30 miles an hour and you hit it,
27:08it's dangerous to you.
27:10You've got a whole buffalo.
27:12Fortunately, the boat clears the carp-filled waters,
27:15and the boaters make it out safely.
27:19Oh, there they go again!
27:22Our deadly dual countdown continues.
27:25But first,
27:26an interspecies exchange with this muscular brute
27:32could end in battle.
27:36Bali, Indonesia.
27:38At the Bali Zoo,
27:40thousands of people visit daily.
27:42And a popular attraction here
27:44are the sometimes ornery orangutans.
27:50The flaps on the sides of the male orangutan's face are called flanges.
27:54And some males develop flanges during their lifetime,
27:58and others never do.
27:59The males who have the flanges are more aggressive
28:02and have higher testosterone levels than the males who don't.
28:05They are signals to other orangutans he may be dominant.
28:09They may also be signals to females that he would be a good mate.
28:15Thirty-eight-year-old Jackie is the park's most famous orangutan.
28:20He's known for tossing food and even feces at park guests.
28:26But one visitor isn't afraid.
28:28He has a plan in mind that goes against any normal zoo's simplest rule.
28:33Don't feed the animals.
28:35But this man wants to prove that, like us,
28:39all primates have the capacity for sharing.
28:43He carefully lifts up a piece of fruit,
28:47aims,
28:48and tosses it across the narrow moat,
28:51right at the giant primate.
28:53For an alpha male primate like this orangutan,
28:57we shouldn't even be looking them directly in the eyes
28:59because that's considered to be a threatening gesture.
29:02We should never throw anything at them.
29:05But the first part of his plan actually works.
29:09The orangutan catches and eats the offering.
29:15There's no sharing without an exchange.
29:18So extending his arms,
29:20the man gestures for the orangutan to return the favor.
29:24With nothing but a narrow moat between them,
29:26the man could be pushing his luck too far.
29:30Orangutans are very agile and strong
29:32and can easily jump five or six feet.
29:35He may not know it,
29:36but this guy is putting himself and maybe others in extreme danger.
29:47Luckily, this time,
29:49Jackie seems to get the spirit of the gift he's been given.
29:52In an amazing display of interspecies communication,
29:57he gently tosses a piece of fruit back in return.
30:01And while you should never do this at any zoo,
30:04it's evidence that man and ape may be more alike than we realize.
30:13Next, in our deadly dual countdown is number four.
30:19Interfere with this sushi lover's meal,
30:21and you might not live
30:25to regret it.
30:30Petropavlovsk, Russia.
30:33All along the coast,
30:34fishing vessels line the docks.
30:37These sturdy ocean vessels carry massive hauls of seafood.
30:41A huge temptation
30:43for some very big and bold ocean mammals,
30:48sea lions.
30:49Sea lions are very efficient hunters,
30:51but they're also lazy, too.
30:52They're going to pick up an easy meal
30:53whenever and however they can.
30:55So they'll do things like follow fishing boats
30:57and grab fish as they fall out of the nets
30:59or any fish that are thrown overboard they'll catch.
31:03Stepping away from their boat
31:05after a day's work,
31:06some exhausted fishermen
31:07return back to discover
31:09a huge problem.
31:11A massive sea lion
31:13has stepped on board their fishing vessel,
31:15and the hungry animal
31:17doesn't seem like it's going to leave
31:18until he gets a meal.
31:22Sea lions may seem playful and friendly,
31:26but a full-grown male
31:27can get bigger than a grizzly bear.
31:30Barking continuously,
31:32the crew's dogs may be biting off more
31:34than they can chew.
31:36Sea lions have several defenses,
31:38one of them being
31:39they have very sharp teeth and claws,
31:40and their bites are pretty extreme.
31:43They also are very heavy.
31:45They can weigh up to a ton,
31:46and they can throw themselves on,
31:48anything that's attacking them.
31:50Nasty.
31:51The barking dogs
31:52are getting more and more agitated,
31:55putting the enormous sea lion
31:57into fight or flight mode.
31:59But which one he'll choose
32:01isn't clear.
32:05Then, one of the fishermen
32:07attempts to soothe the ocean creature
32:09with a tasty treat.
32:11A small fish
32:13from the day's catch.
32:14And it's a very bad idea.
32:19The sea lion decides
32:21the aggressive dogs
32:22are simply getting in the way
32:24of his meal.
32:27He reaches down,
32:29grabs a dog with his powerful jaws,
32:31and flings it
32:33more than 30 feet
32:34out of the boat.
32:36Sea lions are really, really strong.
32:38They're also really, really big.
32:40So, when a sea lion
32:41and a dog
32:42are competing for food,
32:43the sea lion's going to win.
32:47Amazingly,
32:48after flying through the air
32:49and crashing into the dock,
32:51the dog is okay.
32:54Without a doubt,
32:55he'll remember,
32:56you should never get between
32:58a hungry seafood connoisseur
33:00and a fresh catch.
33:04We continue
33:06our deadly duel countdown
33:07with number three.
33:11Here's a deadly duel
33:13where the rat rules.
33:16Moscow, Russia.
33:18In many cities
33:20throughout the country,
33:21the urban jungle is home
33:22to notorious disease-carrying rats
33:25and dangerous predatory felines.
33:29These two have been mortal enemies
33:31for thousands of years.
33:33The cat is a very good predator.
33:36It's a killing machine.
33:37It can get all kinds of rodents
33:39and birds
33:39and normally is very, very efficient
33:42at killing these guys,
33:44and rats would normally be quite terrified.
33:47Here,
33:48in a deserted alley,
33:50a city-dwelling rodent
33:51is enjoying a stroll
33:53along the edge of a fence,
33:54and it's heading straight
33:56toward a gang of feral felines.
34:01It seems like a stroll
34:03to a certain death.
34:05Rats have an extraordinary ability
34:07to smell
34:08and to hear.
34:11Their sense of smell
34:12is like 60 times
34:14better than ours,
34:15so they can hear
34:16or smell the cat
34:17coming from a long way off.
34:20It would normally escape,
34:21but in fact,
34:22in this case,
34:23the very opposite is happening.
34:25Perhaps it's got a family
34:26just on the other side
34:27of the fence.
34:29One of the cats
34:30makes the first move,
34:34stalking its unsuspecting prey.
34:39But as soon as the cat
34:40comes close,
34:43the rat does something
34:45truly shocking.
34:48Instead of flight,
34:50it chooses fight,
34:51lunging violently at the cat,
34:53forcing her to retreat.
35:00Despite the danger,
35:02the rat keeps on charging
35:03again and again,
35:07and his furious assault
35:09may have gone too far.
35:14Now, he's totally surrounded
35:16by the predators,
35:17and there's no way to know
35:19why he's taken such a deadly risk.
35:21This is a very odd behavior
35:23for a rat.
35:24Something appears to be
35:26affecting this rat
35:27in a different way
35:28from what you would normally expect.
35:30Perhaps there's something
35:30going on with its brain
35:32that's not normal.
35:33There's an organism
35:34called toxoplasmosis
35:35that can insist in the brain
35:37and cause strange behavior.
35:41But this rat
35:42will not be beaten.
35:45Gnawing,
35:45clawing,
35:46and striking mid-air.
35:50The rat scares off the felines,
35:52creating an opening
35:54for an unlikely escape.
35:58Before revealing what's next
36:00in our deadly duel countdown,
36:03it's a contest
36:05for India's most dangerous creature,
36:08the mighty cobra,
36:10or the king of the coop.
36:16Andhra Pradesh, India.
36:19Home to 50 million people
36:21and a huge array
36:23of dangerous wildlife.
36:24Residents here
36:25must watch out
36:26for predatory tigers,
36:28territorial elephants,
36:30and venomous king cobras.
36:33What are some
36:34of the deadliest animals in India?
36:36Well, what comes to mind
36:37are Bengal tigers,
36:39crocodiles,
36:40or elephants.
36:41But in fact,
36:42it's venomous snakes.
36:44They kill
36:44up to 50,000 people
36:47a year.
36:49On a normally
36:50quiet street,
36:52a war
36:53is raging.
36:54It's a baby
36:55king cobra
36:56squaring off
36:57against an ordinary
36:59rooster.
37:03The cobra lunges
37:05once,
37:06twice,
37:08three times.
37:09But the rooster
37:10doesn't take the hint.
37:15Then,
37:16he snatches
37:17the killer reptile.
37:18It's a daring move,
37:20but it could be
37:21a death wish.
37:23Roosters have spurs
37:25on the backs
37:26of their legs,
37:27and they have
37:29their beak,
37:30which is very sharp.
37:31But they really are
37:32no match
37:33for a king cobra.
37:34Even as babies,
37:36king cobras
37:37can deliver
37:38a deadly bite.
37:42The serpent
37:43slithers back
37:44toward the roost,
37:45and the rooster
37:46follows,
37:47snatching it
37:48again.
37:49This time,
37:50the rooster
37:50carries the cobra
37:51even further
37:52from his flock.
37:54But this battle
37:56isn't over.
38:01While he holds
38:02the cobra
38:02in his beak,
38:03it strikes.
38:07And this time,
38:09it seems to connect
38:10with the rooster.
38:12Our courageous cock
38:14could already be
38:15a dead bird walking.
38:19In the world
38:20of deadly snakes,
38:22king cobras
38:23can hold their own.
38:25One bite
38:25from a king cobra
38:26can kill
38:2720 adult
38:29human beings.
38:31It can also
38:32take down
38:33an entire elephant
38:34within a couple hours.
38:36So,
38:37it's nothing
38:38to joke about.
38:41That's when
38:42the rooster
38:42does the unthinkable.
38:45Desperate
38:46to finish the duel,
38:48he snatches
38:49up the serpent
38:50and swallows.
38:52It's a shocking
38:53display of brutality
38:55from an ordinary
38:56farm animal.
38:57A cock
38:58could replace
38:59cobras
39:00as India's
39:01most dangerous
39:02beast.
39:06Next,
39:07in our countdown
39:08of deadly duels
39:09is number two.
39:13When an unidentified
39:14flying object
39:15swoops down
39:16on our ancient
39:17ancestor,
39:18will there be
39:19peace
39:20or war?
39:25Arnhem,
39:26Netherlands.
39:27The Royal Burger
39:29Zoo
39:29is one of the
39:30country's biggest
39:31animal parks.
39:32It houses
39:33an array of animals
39:34and some of its
39:35most beloved residents
39:37are the highly
39:38intelligent
39:39chimpanzees.
39:41Chimpanzees are a source
39:42of constant interest
39:43for people
39:43because they're so
39:44similar to us
39:45in their intelligence,
39:46communication,
39:47and tool use skills.
39:49They use rocks
39:50to break open
39:51nuts,
39:51twigs to find
39:53insects and honey.
39:55Today,
39:56a television
39:57crew's filming
39:58at the zoo.
39:58And to capture
40:00a stunning view
40:00of the chimpanzee
40:02enclosure,
40:02they use
40:04a camera drone.
40:06Cruising it
40:06close to 30 feet
40:07off the ground,
40:09the drone
40:09slowly passes over
40:10while several
40:12of the chimps
40:12stare with curiosity
40:14and concern.
40:17None of the apes
40:18is more interested
40:19than Tushi,
40:20a full-grown female.
40:22Sitting high up
40:23on the structure,
40:24she's sizing up
40:25the potential threat
40:26and she's not
40:28empty-handed.
40:30Chimpanzees
40:30are highly
40:31territorial
40:32and would
40:33give up their lives
40:34in order to protect
40:35their territory.
40:36They regularly
40:37patrol the perimeter
40:39of their territory
40:40and viciously attack
40:41any intruders
40:42that they perceive
40:43as threats.
40:46As the drone
40:47flies to within feet
40:48of the determined
40:49primate,
40:50she swings hard
40:51and misses.
40:54The missed opportunity
40:55only fuels
40:56Tushi's anger,
40:57but the drone
40:58is nearly
40:58out of reach.
41:00Chimpanzees
41:01are intelligent
41:01and good with tools,
41:03but precision
41:04is not necessarily
41:05their strong suit.
41:06It's going to be hard
41:07for this chimpanzee
41:08to hit a target
41:09flying in the air.
41:11Tushi takes
41:12one last swing
41:13and hits.
41:15She strikes the drone
41:17out of the sky
41:18and as it tumbles
41:19to a stop,
41:20Tushi's right there
41:22to make sure
41:23this aerial invader
41:24won't bother her troop
41:25ever again.
41:31We're almost ready
41:33to reveal our story
41:34number one,
41:35but first,
41:37in this deadly duel,
41:39it takes all the right
41:40moves to catch a meal.
41:46Sabah, Malaysia.
41:48With a warm climate
41:49and beautiful ocean views,
41:51it's a nature lover's paradise.
41:54So it's no wonder
41:55why a very special
41:56kind of snake
41:57makes its home here
41:58among the lush
41:59rainforest canopy.
42:02The Paradise Tree Snake.
42:04The Paradise Tree Snakes
42:05are also known
42:06as flying snakes
42:08because they actually
42:08glide through the air.
42:10They're almost always
42:11up in trees.
42:12They'll go for birds,
42:14they'll go for small mammals,
42:15they'll go for reptiles,
42:17anything they can get
42:18their teeth around,
42:19they'll go for it.
42:22Luckily, gliding
42:24isn't the only
42:25special skill
42:26these snakes have.
42:28Unbelievably,
42:30high above street level,
42:31one of these
42:31incredible predators
42:32that slithered
42:33into the city
42:34is cruising along
42:35a high-voltage power line
42:37with the delicate grace
42:39of a highly trained
42:40circus performer.
42:44And this balancing act
42:46is not just for show.
42:48This snake is stalking
42:49a potential meal.
42:51A bird on the wire.
42:53What looks like
42:54a little spider hunter.
42:58The bird's not just
42:59going to sit and wait
43:00to become dinner.
43:01With the power
43:02of actual flight,
43:04he could evade
43:05the predator
43:05by simply lifting off.
43:07Yet for some reason,
43:09he stays.
43:10He seems like
43:11he doesn't believe
43:12the snake
43:13can actually catch him.
43:15And the serpent
43:17isn't wasting
43:17the opportunity.
43:18he's trying to get
43:20in position
43:21for a strike.
43:24Then,
43:25the bird makes
43:26a seemingly suicidal move.
43:28He swoops in
43:29just inches
43:31from the snake.
43:32It's the predator's
43:33best chance
43:34to grab dinner.
43:36The bird is
43:36definitely gambling.
43:37It's definitely gambling.
43:39And the snake,
43:40it can definitely
43:40take this bird down.
43:41It's a prey item.
43:42And that bird
43:43sees exactly
43:44where the snake is.
43:45so it's almost
43:46mocking the snake
43:47a little bit.
43:50But the snake
43:51can't strike in time.
43:53And the bird
43:54finally decides
43:55the risk
43:56is too high.
43:58In the end,
43:59no amount
44:00of fancy moves
44:01will guarantee
44:02a full belly.
44:08We're finally ready
44:09to reveal
44:10our deadly duel
44:11number one.
44:15Sometimes,
44:16our own worst enemy
44:19is on the inside.
44:23Papua, Indonesia.
44:25In this lush environment,
44:27the ecosystem's
44:29incredibly diverse.
44:31Here,
44:31animals big
44:32and small
44:33thrive.
44:34And one of the biggest
44:35and deadliest
44:36of the small
44:37is the praying mantis.
44:42Praying mantises
44:43are pretty high up
44:44in the food chain
44:45because they're predators
44:46and they'll take down
44:47basically anything
44:49they can impale
44:49with their raptorial claws.
44:51They're really
44:52large-bodied insects
44:53with a pretty big abdomen
44:55that they use
44:56for laying eggs.
44:57This massive predator
44:58sits at the top
45:00of the insect food chain.
45:02But she's not
45:03without enemies.
45:04And here,
45:05in this ordinary
45:06bowl of water,
45:07an invasion
45:08has already happened
45:10on the inside.
45:13Whoa.
45:14Are you kidding me?
45:18A slender,
45:20black thing
45:20slowly slips
45:22out of the mantis's
45:23abdomen.
45:24And at first,
45:25it's not clear
45:26what's happening.
45:28But while the mantis
45:29struggles to get out,
45:30it's no use.
45:32There's no way
45:33to escape this invader,
45:35a deadly parasite
45:36known as the horsehair worm.
45:40The horsehair worm
45:42needs water to reproduce,
45:43so it has to lay its eggs
45:44back in water again.
45:45It releases chemical signals
45:47to the host's brain
45:48that make the host,
45:50the praying mantis,
45:51seek out water
45:52because water is where
45:53the horsehair worm
45:54wants to go.
45:57With each centimeter
45:58of worm that comes out,
46:00it's hard to imagine
46:01what could be left
46:02inside this mantis's body.
46:05And yet it still moves,
46:07fighting to free itself.
46:09You've never seen anything
46:10so gross in your life.
46:12And as the last bits
46:13of worm wriggle
46:14out of his body,
46:15it's not just one,
46:18but three in total.
46:21Hey, come here.
46:22Come here,
46:23we want to save you.
46:25With each passing moment,
46:26the giant insect
46:28gets weaker
46:28and weaker.
46:30Because horsehair worms
46:31take up so much nutrients
46:32from the host
46:33as they're growing
46:34inside of it,
46:35the host almost always dies,
46:37but not 100% of the time.
46:40It might be too late
46:41for this guy.
46:42Unfortunately,
46:43this time,
46:44the praying mantis
46:45doesn't survive
46:46the grotesque invasion.
46:50Within weeks,
46:52the adult worm
46:53will lay more eggs
46:54that will one day
46:55infect a new host,
46:57ensuring that this circle
46:59of painfully disturbing life
47:01continues.
47:03Whoa.
47:04Are you kidding me?
47:07They're frightening,
47:08fierce,
47:09and always alarming.
47:11Help him.
47:12Insane, deadly duels
47:13that show
47:14in wild nature,
47:15there are no boundaries,
47:17and there's always
47:19more to come
47:19on weird,
47:21true,
47:21and freaky.
47:23God,
47:24you're a big time.
47:26There you are.
47:32You
